REVISION OF SPIX'IES OF THE GENUS AGROTIS. 'A\ 



The type of hrHnneipennis is an extreiiic form, and Mi'. (Irote'sde- 

 sciii)tion may tlioivf'ore be re|)ro(ln(;e(l: 



"Allied to cupidd but snniller ; fore-tibia' unarmed; thorax and fore- 

 wiufjs of a glossy chestnut brown, somewhat reddish ; none of the usual 

 markings are noticeable. Tiie sub-terminal space is stained with black- 

 ish. Following the s. t. line is a series of faint, pale, interspaceal Heck- 

 iugs; ordinary lines indicated on costal region. Hind wings blackish 

 fuscous; abdomen beneath stained with reddish brown, as is the costal 

 region of primaries, else the bhickish wings benrath show only a com- 

 mon black transverse line, which fades out toward the internal mar- 

 gins." 



Lintner, in the Ent. Cont., IV, 124, rather doubts the iilentity of the 

 forms referred by Mr. Orote to this species, and describes the larval 

 habits of the species without describing the larva itself. According 

 to him it is sometimes quite injurious to grape, feeding on the buds. 



The si)ecies is the most common eastern rei)resentative of its group. 



Mr. Butler's reference of Graphiphora vclata Wlk. as a synonym of 

 this species, is accepted as an easy way of getting rid of Walker's name, 

 and because the reference is probably correct.

"Fuscous gray. Fore wings smooth, dark fuscous. Basal and sub- 

 terminal spaces blackish and darkest; median space a little lighter, 

 slightly brownish; terminal space gray, contrasting. Lines even, per- 

 pendicular, i)ale. Transverse anterior line with a slight subcostal notch, 

 slightly oblique; median si)acewide; stigmata diOicult to make out, 

 pale ringed, concolorous; median shade noticeable, obscuring the reni- 

 form. Transverse posterior line with a straight, outward costal ex- 

 tension beyond the point of origination, thence somewhat squarely 

 exserted opposite the ceil, and running nearly straight downwards with- 

 out submedian sinus. Subterminal line indicated by the great difter- 

 ence in color between the two terminal spaces; fringes dark. Hind 

 wings concolorous, rather dark fuscous, with i)aler, interlined fringes. 

 Beneath, fuscous, with a slight puri>ly shade, irrorate, witii an external 

 common band inconqilete; a sliglit discal mark on hind wings. Ternii- 

 nal abdominal hairs somewhat oclierous." 



The above description is from Mr. Grote, to show the type form of the 

 species, it was from a specimen taken by i\Ir. Hill in Lewis County, 

 New York, July 26. 



In Can. Ent., x, 235, IMr. Grote, commenting on four specimens from 

 Nevada, says: "One has the fore wings shaded with brown, median 

 and terminal space both paler, markings (piite distinct. Another is 

 almost unicolorous blackish, with the shadings and markings jwwdery.
