Genus PLUSIA Hübner

Three of the four species attributed to the genus as found in America are represented upon our plate.

(1) Plusia ærea Hübner, Plate XXVIII, Fig. 16, 8.

The moth ranges from Nova Scotia to Florida and westward to Texas and the region of the Rocky Mountains.

(2) Plusia æroides Grote, Plate XXVIII, Fig. 17, 3.

The distribution of this species is almost identical with that of Plusia area. The larva feeds on various species of Spiræa. (3) Plusia balluca Geyer, Plate XXVIII, Fig. 22, 9. The species is not uncommon in the northern Atlantic States.

Genus EUCHALCIA Hübner

(1) Euchalcia contexta Grote, Plate XXVIII, Fig. 23, 8. The species is found from Maine to Wisconsin, and occasionally as far south as the mountains of central Pennsylvania.

(2) Euchalcia putnami Grote, Plate XXVIII, Fig. 15, 3. Dr. Dyar with questionable correctness treats this species as a form of the European festuca Linnæus. There is no doubt of the distinctness of the two.

(3) Euchalcia venusta Walker, Plate XXVIII, Fig. 21, 9. Syn. striatella Grote.

The range of this species is from Nova Scotia and Canada southward to the mountains of West Virginia.

Genus EOSPHOROPTERYX Dyar

(1) Eosphoropteryx thyatiroides Guenée, Plate XXVIII, Fig. 18, .

This lovely moth is still very rare in collections. It ranges from New England and Canada to the mountains of Virginia and westward into the Valley of the Mississippi.

(1) Autographa bimaculata Stephens, Plate XXVIII, Fig. 19, 6.

Syn. u-brevis Guenée.

This is a common species in the northern Atlantic States.

(2) Autographa biloba Stephens, Plate XXVIII, Fig. 24, 3. The species is distributed widely from the Atlantic to the Pacific.

(3) Autographa verruca Fabricius, Plate XXVIII, Fig. 20, ¿. Syn, omega Hübner; oo Cramer; omicron Hübner; questionis Treitschke; rutila Walker.

The moth is scarce in the northern Atlantic States, but has been recorded as occurring in Massachusetts. It ranges from New England to Texas and southward through Central and South America.

(4) Autographa rogationis Guenée, Plate XXVIII, Fig. 25, 8. Syn. hamifera Walker; dyaus Grote; includens Walker; culta Lintner. The range of this species is the same as that of the preceding.

(5) Autographa precationis Guenée, Plate XXVIII, Fig. 28, 8.

The insect is found in Canada and the United States east of the Rocky Mountains.

(6) Autographa egena Guenée, Plate XXVIII, Fig. 29, 8. This is a southern species, occurring in Florida and the Gulf States, and ranging southward into South America.

(7) Autographa flagellum Walker, Plate XXVIII, Fig. 27, 8. Syn. monodon Grote; insolita Smith.

The species ranges from Quebec to Alberta.

(8) Autographa pseudogamma Grote, Plate XXVIII, Fig. 35, 8.

The insect is indigenous in Quebec and Nova Scotia.

(9) Autographa ou Guenée, Plate XXVIII, Fig. 33, 8.

Syn. fratetta Grote.

This species is almost universally distributed through the United States and southern Canada.

(10) Autographa brassica Riley, Plate XXVIII, Fig. 36, 5. Syn. echinocystis Behr.

This insect, which preys upon the Cruciferæ in its larval state, has been well described and its habits fully set forth by Prof. C. V. Riley in the Missouri Reports. It is from his paper upon the species that we have been permitted to extract the figure which is herewith annexed of the insect in its various. stages. The moth appears to be very

(11) Autographa oxygramma Geyer, Plate XXVIII, Fig. 30, 8.

Syn. indigna Walker.

The moth is found in the southern States, and thence southward to South America.

(12) Autographa rectangula Kirby, Plate XXVIII, Fig. 32, 9. Syn. mortuorum Guenée.

This lovely species is northern in its range. abundant one summer at Saratoga, New York.

(13) Autographa vaccinii Henry Edwards, Plate XXVIII, Fig. 34, .

This species may easily be distinguished by the strongly checkered fringes of the primaries.

(14) Autographa selecta Walker, Plate XXVIII, Fig. 39, 8. Syn. viridisignata Grote.

This is a somewhat large species, not very attractively colored. It is northern in its range.

(15) Autographa angulidens Smith, Plate XXVIII, Fig. 38, .

The species is found in Colorado, and probably has a wide range in the Rocky Mountains.

(16) Autographa ampla Walker, Plate XXVIII, Fig. 31, 9. This fine species is northern in its range, but extends its habitat southward along the ranges of the great mountains of the west.

(17) Autographa basigera Walker, Plate XXVIII, Fig. 26, ♂ . Syn. laticlavia Morrison.

The insect occurs in the Appalachian subregion.

(18) Autographa simplex Guenée, Plate XXVIII, Fig. 37, 8. This is one of the very commonest species of the genus, which is apparently universally distributed throughout our country.

Genus SYNGRAPHA Hübner

This genus is composed of species which are subpolar in their habitat. Of the four species which are reckoned as belonging to the fauna of North America, we illustrate two.

(1) Syngrapha hochenwarthi Hochenwarth, Plate XXVIII, Fig. 41, .

Syn. divergens Fabricius.

Found everywhere in Arctic America. The specimen figured was taken in Labrador.

(2) Syngrapha devergens Hübner, Plate XXVIII, Fig. 40, 9. Syn. alticola Walker.

The species is found in Labrador, and has been reported from the high mountains of Colorado. It will probably be found to have a wide range.

Genus ABROSTOLA Ochsenheimer

We give representations of both the species which occur in

our fauna.

(1) Abrostola urentis Guenée, Plate XXVIII, Fig 42, 8. The insect, which is by no means common, is found in the Appalachian subregion.

(2) Abrostola ovalis Guenée, Plate XXVIII, Fig. 43, 3. The range of this insect is the same as that of the last mentioned.
