Genus PTERÆTHOLIX Grote

(1) Pterætholix bullula Grote, Plate XXIX, Fig. 8, 8. The habitat of this little moth is the Gulf States.

Genus Alabama Grote

(1) Alabama argillacea Hübner, Plate XXIX, Fig. 11, 8. (The Cotton-worm Moth).

Syn. xylina Say; grandipuncta Guenée; bipunctina Guenée.

The Cotton-worm Moth is one of a number of insects which annually inflict a vast amount of damage upon the crops in the southern por

tion of our country. In Prof. Com stock's "Report upon the insects which are injurious to cotton," published in 1879, and in the "Fourth Report of the United States Entomological Commission," there is given

larva; c. lateral view of mature larva; d. dorsal view of mature larva; e. leaf in which pupation takes place; f. pupa. (After Riley.)

a great deal of valuable and interesting information in regard to this species. Much may also be learned about it from the study of the "Missouri Reports" published by the late Prof. C. V. Riley. The range of the insect is very broad. It sometimes, though very rarely, occurs as far north as Canada. From this northernmost location it has been found ranging southward as far as Argentina. It sometimes appears to migrate in swarms. A number of years ago, during a heavy snowstorm in November, myriads of the moths suddenly appeared in the city of Pittsburgh, and they came flying in the evening to the electric lights. From one store the proprietor said that he had swept them out by the

quart. I have a few of the insects which thus appeared, and the figure on the plate is taken from one of these specimens.

Genus ANOMIS Hübner

The species belonging to this genus are mainly southern. There is considerable uncertainty as to the identification of some of the species, which were named by the older authors. Of the four reputed to be found within our limits we figure the one which is commonest.

(1) Anomis erosa Hübner, Plate XXIX, Fig. 12, Occasionally found as far north as New England. thence southward into the South American continent.

Genus SCOLECOCAMPA Guenée

.

Ranging

The only species of the genus so far known to occur in the United States was named liburna by Geyer. Guenée subsequently called it ligni. The larva feeds in decaying wood, particularly that of oaks, chestnuts, and hickories. It tunnels its way through the softer parts, and after reaching maturity makes a loose cocoon composed of a few strands of silk mixed with chips and the frass left in the burrow, from which it emerges in due season as the moth, which is represented on Plate XXIX, Fig. 16, by a male specimen.

Genus EUCALYPTERA Morrison

A small genus, the species of which are confined to the southern States and to Mexico and Central America.

(1) Eucalyptera strigata Smith, Plate XXIX, Fig. 9, 3. The habitat of this species is Texas.

Genus CILLA Grote

(1) Cilla distema Grote, Plate XXIX, Fig. 10, ♂ .

This obscure little moth, the only representative of the genus in our territory, has hitherto only been reported from Texas.

Genus AMOLITA Grote

(1) Amolita fessa Grote, Plate XXIX, Fig. 13, 8.

The moth occurs from Massachusetts to Florida and westward

to Texas and Colorado.

Genus RIVULA Guenée

(1) Rivula propinqualis Guenée, Plate XXIX, Fig. 14, 9. The range of this insect is from Nova Scotia to Texas, and across the continent as far as the Rocky Mountains.

Genus PSEUDORGYIA Harvey

(1) Pseudorgyia versuta Harvey, Plate XXIX, Fig. 17, 3. This insect is thus far only known to us from Texas.

Genus DORYODES Guenée

(1) Doryodes bistriaris Geyer, Plate XXIX, Fig. 15, 8. Syn. acutaria Herrich-Schæffer; divisa Walker; promptella Walker. There are three species of the genus found in our territory, one of them, so far as is known to the writer, as yet unnamed. The insect we are considering ranges from Maine to Florida and westward to Colorado.

Genus PHIPROSOPUS Grote

(1) Phiprosopus callitrichoides Grote, Plate XXIX, Fig 18, 9.

Syn. nasutaria Zeller; acutalis Walker.

The species ranges from New York to Texas.

Genus ANEPISCHETOS Smith

The only species thus far referred to this genus, which was erected by Smith in 1900 for its reception, received at the hands of that author the specific name bipartita. A figure of the type, which is contained in the collection of the United States National Museum, is Anepischetos bipargiven in the accompanying cut.

Genus DIALLAGMA Smith

พ.ร.

FIG. 152.

tita, . .

This genus was erected at the same time as the preceding by the same author for the reception of the insect of which we give a representation in Fig. 153. Its habitat, as FIG. 153. Diallag- also that of the last mentioned species, is

ma lutea, . 1.

Florida.

Genus PLEONECTYPTERA Grote

This is a genus of moderate size, which by some writers has heretofore been placed among the Pyralidæ, though it is undoubtedly correctly located among the Noctuida. Eight species are credited to our fauna in the latest catalogue.

(1) Pleonectyptera pyralis Hübner, Plate XXIX, Fig. 19, f. Syn. irrecta Walker; floccalis Zeller.

The insect ranges through the southern Atlantic States to Central and South America.

Genus ANNAPHILA Grote

A genus of moderate extent, embracing over a dozen species, which are found within the United States.

(1) Annaphila diva Grote, Plate XXIX, Fig. 20, 3.

The habitat of this pretty little moth is California.

(2) Annaphila lithosina Henry Edwards, Plate XXIX, Fig. f.

21, .

The specimen figured in the plate came from southern California.

Genus INCITA Grote

Only a single species, the type of the genus, is known. The figure we give in the annexed cut is drawn from the type in the

possession of the American Museum of Natural History in New York.

Genus TRICHOTARACHE Grote

The sole representative of this genus in our fauna is the insect the type of which is given in the accompanying figure, drawn for this work by Mr. Horace Knight, of London.

FIG. 155.-Trichotarache assimilis Grote, f. 4.

The habitat of the moth is California.

Genus EUSTROTIA Hübner

This is quite an extensive genus, of which eighteen species are included in our fauna. Of this number we give illustrations of seven.

(1) Eustrotia albidula Guenée, Plate XXIX, Fig 22, 9.

Syn. intractabilis Walker.

This little moth ranges from the Atlantic to the Mississippi, and further west.

(2) Eustrotia concinnimacula Guenée, Plate XXIX, Fig. 23, 9.

Not an uncommon species in the Atlantic subregion.

(3) Eustrotia synochitis Grote & Robinson, Plate XXIX, Fig. 24, ô.

The distribution of this species is the same as that of the last. It occurs from Canada to Texas.

(4) Eustrotia musta Grote & Robinson, Plate XXIX, Fig. 25, 8.

Found from the Atlantic to the Rocky Mountains.

(5) Eustrotia muscosula Guenée, Plate XXIX, Fig. 26, . The moth has the same ranges as the last mentioned species. It is very common in Indiana.

A very common species, having the same range as its prede

cessor.

(7) Eustrotia carneola Guenée, Plate XXIX, Fig. 28, . Syn. biplaga Walker.

What has been said of the last species applies also to this, except that it is, if anything, even more common.
