DESCRIPTIONS OF NEW SPECIES OF PHYTOPHAGOUS COLEOPTERA RECEIVED BY MR. J. H. LEECH, FROM CHANG-YANG, CHINA.

BY MARTIN JACOBY, F.E.S.

(Continued from p. 89.)

DIORYCTUS VARIABILIS, n. sp.

Black; the head, antennæ, thorax and the legs fulvous; elytra black, extremely finely punctate-striate.

Var. Head and thorax nearly black. Length 1—14 line.

Head with a few extremely fine punctures, visible only under a strong lens; eyes slightly but broadly emarginate, the emargination rounded; antennæ entirely fulvous, short, the terminal joints lightly and gradually thickened; thorax of the same shape as in the preceding species, and similarly coloured, entirely impunctate; scutellum invisible; elytra with the basal lobe scarcely produced, black, the punctured striæ scarcely perceptible; legs fulvous; prosternum much broader than long, its surface flat without anterior projection.

This small species is similarly coloured as the preceding, but differs totally from it in the nearly impunctate head and elytra, their shape, and the structure of the prosternum; the variety does not seem to differ, except in its almost entirely black colour.

AORIA CHINENSIS, n. sp.

Fulvous, pubescent; the antennæ (the basal joints excepted), the apex of the femora and the tibiæ, black; thorax coarsely punctured; elytra depressed below the base, punctate-striate, the interstices more or less costate.

9. Elytra more strongly costate.

Var. Head or thorax black; legs entirely fulvous. Length, 2-3 lines. A. chinensis, although closely allied to A. nigripes, Baly, and A. bowringii, is quite distinct; the head, which is either fulvous or black, is closely punctured; the antennæ are black with the exception of the lower four joints, which are fulvous, they extend nearly to the end of the body; the thorax is less globose than in the allied species, more transverse in shape and has an obsolete transverse depression at each side, the surface is coarsely punctured and clothed with fulvous pubescence; the elytra are

similarly pubescent, and have a distinct oblique depression at the base, which is absent in A. nigripes and A. bowringii; the punctures are transverse in shape and frequently arranged in double rows, the interstices are slightly convex, in most specimens the legs are black, with the base of the femora fulvous; in others the head, antennæ and legs are entirely black.

Several specimens.

TALMONUS, Fairm.

This genus, recently described by M. Fairmaire, seems to me to be identical with Lypesthes, Baly, and his species, T. farinosus, with L. ater, Motsch. (pulverulentus, Jac.). This is, therefore, the third time that Motschulsky's species has been described under different names.

Many specimens.

NODOSTOMA ORIENTALE, n. sp. (Pl. I. fig. 7).

Greenish-æneous, the base of the antennæ and of the femora, fulvous; head and thorax closely and finely punctured, the sides of the latter subangulate: elytra strongly punctate-striate, the base conxex; femora with a minute tooth.

Elytra less regularly and subgeminate punctate-striate.

9. Elytra very regularly punctured, with a short oblique costa below the shoulders. Length, 2 lines.

3. Of dark greenish-æneous colour, the head rather closely and strongly punctured and subrugose, the epistome not separated from the face; labrum fulvous; antennæ about half the length of the body, the lower four joints fulvous, the first stained with black above; thorax about twice as broad as long, the sides distinctly angulate at the middle, the surface rather closely but somewhat less strongly punctured than the head; elytra with the base distinctly swollen and depressed below the raised portion, the base rather irregularly punctured, the striæ more regular posteriorly but here and there appearing double, the shoulders prominent, forming a slight ridge; the femora with a very minute tooth.

N. orientale seems closely allied to N. puncticolle Weise, also from China, but differs in the punctured clypeus, the angulate sides of the thorax and the swollen base of the elytra; the latter is much more distinctly visible in the female, which may be mistaken for another species, since the elytral punctuation is very strong and regular throughout, a short but strong oblique costa extends from the shoulder to the lateral margin, all other characters agree with that of the male; both sexes were obtained in sufficient numbers.

NODOSTOMA GIBBOSUM, n. sp.

Oblong-ovate, widened behind, dark æneous; the labrum, base of the antennæ and base of the femora and tibiæ fulvous; thorax closely and strongly punctured; elytra convex, strongly widened, finely punctate-striate. Length, 1 line.

Head closely and strongly punctured, the vertex subrugose, the epistome also strongly punctured, separated from the face by an obsolete transverse depression, its anterior edge deeply concave-emarginate; labrum and palpi fulvous; antennæ black, the lower three joints fulvous, the first stained with

piceous above; thorax about one half broader than long, the sides rounded and widened, very obsoletely angulate below the middle, the anterior angles slightly pointed, the surface very strongly and rather closely punctured, a narrow longitudinal central space as well as the extreme anterior margin, smooth; elytra convex, strongly rounded towards the middle and pointed at the apex, the punctures rather finely impressed but distinct to the apex, the base with a shallow transverse depression, only visible in certain lights, the interstices above this depression subtuberculate (male), or subcostate (female), the sides in the female also furnished with a short costa below the shoulder and a longer one further inwards; the four posterior femora minutely toothed.

This species, which has all the characters peculiar to the genus, is much distinguished by its shape and the sculpture of the elytra; the thorax also is longer than is usually the case, and its sides are scarcely angulate.

A few examples.

CLEORINA LEFEVREI, n. sp.

Metallic dark blue or violaceous; antennæ black, the basal two or three joints fulvous; finely and moderately closely punctured; elytra with a transverse depression below the base, finely punctate-striate. Length, 1-1 line.

Of broadly ovate shape, the head rather closely and distinctly punctured, the epistome not separated from the face, the anterior edge of the clypeus deeply concave-emarginate; antennæ less than half the length of the body, black, the third and fourth joints of equal length, the lower three fulvous, the basal joint stained with metallic-blue above; thorax transverse, twice as broad as long, the sides nearly straight, the surface punctured like the head, the punctures subremotely placed; scutellum impunctate, broad, its apex acute; elytra with a deep transverse depression below the base, the shoulders prominent, the punctured striæ fine (except within the depression), nearly indistinct at the apex.

Closely allied to C. janthina, Lefèv., but quite distinct. Numerous specimens were obtained.

CHRYSOMELA SERIEPUNCTATA,? Weise.

The description of this Chrysomela from Siberia, by the author in Wiegmann's Archiv,' 1887, agrees so closely with the specimens from Chang Yang, that I must refer them to that species, the more so as the very numerous and variable species already described, from the East, are for the greater part very difficult to separate. The present insect is entirely metallic dark blue, the thorax is very finely and rather closely punctured on the disc (Weise says not closely), and the sides have a deep row of coarse punctures (deepest near the base), which limit the nearly smooth lateral and slightly raised marginal space; the elytra have numerous rows of strong punctures, which only at the sides can be distinguished as being arranged in pairs, the interstices are nearly as strongly, sometimes more finely, punctured. All this agrees with the author's description.

CHRYSOMELA SIBIRICA, Weise.

Numerous specimens, agreeing entirely with the author's description, were obtained by Mr. Pratt; the upper surface of the

insect is of a violaceous-cupreous colour; the thorax is very finely punctured on the disc, coarsely at the sides, which latter have a deep longitudinal depression at the base; the elytra have four double rows of deep punctures, with numerous finer ones on the interstices.

PHYTODECTA FLAVO-PLAGIATA, n. sp. (Pl. I. fig. 8).

Black; the head, apical joints of the antennæ, and the legs partly, fulvous; thorax finely punctured; elytra more strongly and semi-regularly punctate, black, a transverse spot on the shoulder and another near the apex, flavous. Length, 24-3 lines.

Of subquadrate and moderately convex shape, the head fulvous, finely and rather closely punctured; antennæ not extending beyond the thorax, the lower five joints fulvous, the others black, very broadly dilated; thorax about three times broader than long, the sides rather strongly rounded, the surface finely and rather closely punctured on the disc, the punctures of various size, those at the sides much larger, the lateral margins slightly thickened, smooth and fulvous, the rest of the disc black; scutellum very broad, impunctate; elytra not broader at the base than the thorax, more strongly punctured than the latter, the punctures partly arranged in rows, the shoulders with a transversely-shaped flavous spot, and another one of similar shape placed at the sides and at some distance from the apex; the under side and legs nearly black, the femora and tibiæ more or less fulvous. Easily known from its congeners by the coloration of the elytra; the subapical spot of the latter is generally more or less constricted at its middle. Four specimens.

MELASOMA MACULICOLLIS, n. sp. (Pl. I., fig. 9.)

Metallic violaceous blue; thorax flavous, finely punctured with five spots, placed transversely; elytra semi-regularly punctured, longitudinally impressed below the shoulder; sides of abdomen fulvous, spotted with black. Length, 5-6 lines.

Head finely punctured at the sides; antennæ not extending beyond the thorax, the terminal joints gradually thickened, black, the basal four joints more or less fulvous below; thorax narrowly transverse, the anterior margin concave at the middle, the sides strongly rounded anteriorly, the surface very finely punctured, flavous, with five black spots, a small one at each side, another at the middle of the base, and two large spots at the middle of the disc; scutellum black; elytra broader than the thorax, metallic dark blue, rather closely and finely punctured, the punctures arranged partly in single or double rows; a short distinctly raised costa is seen in front of the shoulder near the base (female), which in the male insect is replaced by a longitudinal smooth space; the shoulders are prominent and swollen; the underside and legs are metallic blackish blue, but the sides of the abdomen are bright flavous, each segment having a black spot at the sides, the last segment with two central spots.

Of this large and handsome species several specimens were obtained; the elytral short costa in the female is very peculiar, and is followed at the sides below the shoulder by a short longitudinal groove, visible in both sexes.

PHYLLODECTA MULTIPUNCTAta, n. sp.

Metallic dark blue; the head and thorax closely punctured, elytra deeply punctate-striate, the striæ rather irregular, the interstices finely

punctured and somewhat rugose; margins of the abdominal segments fulvous; tarsi piceous. Length, 13 line.

Head distinctly and closely punctured; antennæ black, the basal two joints fulvous below, the third joint longer than the fourth and second joint, the terminal ones strongly thickened; thorax transverse, twice as broad as long, the sides nearly straight, the surface finely but rather closely punctured with an obscure central smooth narrow ridge; scutellum black, impunctate; elytra with deeply punctured striæ, which are occasionally doubled and distinct to the apex, the interstices very slightly raised, finely punctured, and at the sides slightly rugose; under side of a more dark greenish-æneous colour, with the extreme margins of the abdominal segments fulvous; tarsi piceous. This species, although closely allied to several others, described by Motschulsky, seems to differ in the close punctuation of the thorax, the sculpture of the elytra, and the colour of the under side.

PAROPSIDES MACULICOLLIS, n. sp. (Pl. I., fig. 10.)

Fulvous; head black in front; thorax very closely punctured, the base, lateral margins, and a central stripe, black; scutellum black; elytra semiregularly punctured, the lateral and sutural margins, a transverse band near the middle, another below the latter, and a longitudinal stripe at the shoulder, black. Length, 3-4 lines.

Head very finely and closely punctured, black, the base with a fulvous spot; antennæ fulvous, not extending beyond the thorax; thorax three times broader than long, very finely and closely punctured, the sides with a small fovea, the disc fulvous, the sides broadly, and a narrow central longitudinal stripe black, the base with another black, medially widened transverse band; elytra with numerous rows of strong punctures, the interstices nearly as strongly punctured, the disc fulvous, the sutural and lateral margins narrowly black, a similarly coloured transverse band is placed near the middle, extending across the suture, where it is greatly widened; this band is joined by a longitudinal black stripe, extending from the shoulder downwards; another transverse narrow band, triangularly widened at its middle, extends across the disc below the middle; prosternum raised and truncate in front; breast and legs sometimes fulvous.

This species closely resembles P. 12-maculata, Gebl., but is, I think, quite distinct, since the differences are constant in more than the fifty specimens which are contained in this collection; the colour of the thorax is different from that of the allied species, the pattern of the elytra partly resembles it, but the third transverse apical stripe in P. 12-maculata is absent in the present insect, the punctuation of the elytra is distinctly stronger, and the larger punctures are more regularly placed in rows.

PAROPSIDES (PHYTODECTA) NIGRO-SPARSUS, Fairm.

The description given by M. Fairmaire of this species surely proves that it cannot belong to the genus Paropsides; the triangularly dilated tibiæ and shape of the prosternum doubtless belong to Phytodecta, and Fairmaire's species seems to be identical with Phytodecta 13-maculata, Jac., described in the Proc. Zool. Soc., 1888, also from China; the only difference I can see is the absence of the lateral spots of the thorax in Fairmaire's species, and its somewhat larger size.
