Genus PLATHYPENA Grote

Only one species of the genus is known to occur within our territory.

(1) Plathypena scabra Fabricius, Plate XLII, Fig. 14, 8. Syn. erectalis Guenée; palpalis Haworth; crassatus Haworth; obesalis Stephens.

Universally distributed through the United States and Canada east of the Rocky Mountains.

Genus HYPENA Schrank

The genus is found in all parts of the globe. Three species are known to be found in our territory. Of these we figure the one which is commonest.

(1) Hypena humuli Harris, Plate XLII, Fig. 12, 8; Fig. 13,

, var.

Syn. evanidalis Robinson; germanalis Walker.

This insect, the larva of

which does considerable damage to the hop, is widely distributed over the whole of the United States and Canada. It is somewhat variable in the shade of the wings and the amount of maculation upon them. For an account of the habits of the insect and the best manner to guard against the ravages which the larva commits the reader is referred to the excellent article by Dr. L. O. Howard of the Department of Agriculture in Washington upon insects injurious to the hop-vine, which was published as the Seventh Bulletin of the New Series of Bulletins issued by the Division of Entomology of the Department.

FAMILY NYCTEOLIDÆ

"An vnredy reue thi residue shal spene,

That menye moththe was maister ynne, in a mynte-while."
PIERS PLOWMAN (C) xiii, 216.

THE Nycteolidae are related to the Noctuidæ, many of the genera, especially in the Old World, containing moths which are green in color and frequent trees. The apex of the fore wing is more or less produced to a point. The larvæ have eight pairs of legs, and are fleshy, with the anal somite tapering to a point. They are either naked or slightly pubescent. But two genera are found in the United States.

Genus NYCTEOLA Hübner

The genus is represented in both the Old World and the New. Two species are found in the United States.

(1) Nycteola revayana Scopoli, form lintnerana Speyer, Plate XLII, Fig. 15, 3.

A large number of synonyms and subspecific forms have been erected by authors who have dealt with this species. The form which we figure is the one which is most commonly encountered in our territory.

Genus HYBLEA Fabricius

This genus is extensively developed in the warmer portions of the Eastern Hemisphere, but is represented by only one species in our region.

(1) Hyblæa puera Cramer, Plate XXX, Fig. 8, 9.

Syn. saga Fabricius; mirificum Strecker.

The insect, which is common in the tropics of the two hemispheres, occurs occasionally in Florida. The specimen figured on our plate is contained in the collection of the United States National Museum.

FAMILY PERICOPIDÆ

(HYPSIDE Auctorum)

"Loose to the wind their airy garments flew,
Thin glittering textures of the filmy dew,
Dipt in the richest tincture of the skies,
Where light disports in ever-mingling dyes,

While every beam new transient colours flings,

Colours that change whene'er they wave their wings."
POPE.-Rape of the Lock.

The following characterization of the family is taken from Hampson's "Moths of India," Vol. I, p. 495: "Proboscis present. Palpi smoothly scaled; the third joint long and naked. Legs smooth; mid tibiae with one pair of spurs, hind tibiae with two pairs. Frenulum present. Fore wing with vein 1a separate from 1b; ic absent; 5 from near lower angle of cell. Hind wing with veins 1a and 1b present, ic absent; 5 from near lower angle of cell; 8 free from the base and connected by a bar with 7 at middle of cell.

"Larva with all the legs present, sparsely covered with long

hairs.

"Cocoon slight.”

Genus DARITIS Walker

A small genus of rather showy moths, which is represented in our fauna by two species.

(1) Daritis thetis Klug, Plate XXXVIII, Fig. 5, 9.

The insect occurs in southern Arizona.

Genus COMPOSIA Hübner

(1) Composia fidelissima Herrich-Schæffer, Plate XXXVIII,

Fig. 4, .

Syn. olympia Butler.

This very beautiful moth is found throughout the Antilles and in southern Florida. It is the only representative of its genus which occurs within our territory.

Genus GNOPHÆLA Walker

Three species of this genus are found within the limits of the United States. Others occur in Mexico and Central America. (1) Gnophæla latipennis Boisduval, Plate XXXVIII, Fig. 2, 3.

Syn. hopfferi Grote & Robinson; discreta Stretch; arizona French; morrisoni Druce.

The habitat of this species is the southwestern portion of our territory and northern Mexico.

(2) Gnophæla vermiculata Grote & Robinson, Plate XXXVIII, Fig. 3, 3.

Syn. continua Henry Edwards.

The moth is found from southern Colorado westward and south-westward.

(3) Gnophæla clappiana Holland, Plate XXXVIII, Fig. 1, 8. The figure on our plate represents the type of the species, which was taken at Colorado Springs. It occurs from central
