REVISION OF SPKCIES OF THE GENUS AGROTIS 59 



To the courtesy of Mr. Moescliler I owe an o[)[K)itiiiiity of comparing 

 his type of wockei with the type of scropuUina, received from Mr. 

 Tepper. They are unquestionably specifically identical, though the 

 types are apparently the extremes of the species. Other specimens 

 fronrNew Hampshire fdl the gap completely. Mr. Grote was entirely 

 in error in referring scropulaiia to carnea, and seems never to have beoii 

 able to realize the distinction between them,thongh he himself pointed 

 out one of the strong characters offered by the course of the basal 

 line. The antennal differences in the male are obvious, and should not 

 have escaped notice. Mr. INIocschler's species seems to have escaped 

 recognition heretofore, and it is due to a liberal scientific spirit on the 

 part of that author iu sending me the specimens that I have beeu able 

 to study his species. 



Genus SETAGROTIS Smith. 



All the tibife spiuose, anterior not very heavily armed, and scarcely 

 abbreviated. Front smooth, not protuberant. Antenmewith the joints 

 marked, laterally furnished with tufts of bristly hair, resembling those 

 of Carncades, but scarcely so well developed. The vestiture consists 

 of flattened hair and scales, forming on the thorax an indefinite, ante- 

 rior divided crest. The palpi are short, the second joint very broad at 

 tip, terminal joiut minute, resembling very much the structure In 

 cu2)i(1a. 



In antennal structure this genus tends to the Carncades series, and 

 furnishes another of the links connecting the extremes like Carncades 

 and Rhynchagrotis. It resembles the latter much less than does Aha- 

 grotis, adding to the characters of the latter, spiuose fore tibiie and a dif- 

 ferent wing form. 



Twospecies, ^>/a/i//VoM.v and conr/rua, are referable here, agreeing in 

 general type of maculation, yet easily distinguishable by a large series 

 of characters, the most obvious of which are the black tipped collar 

 and black basal dash in plani/rons, while iu congrua the collar is red- 

 dish tipped, and there is no basal dash. 



Setagrotis planifrons Smith. 

 18'JO. Smitli, Trans. Am, Ent. Soc, xvxi, Al, Agrotis. 



General color a bluish ash-gray; sides of palpi blackish; collar 

 black tipped ; thorax immaculate. Primaries with a distinct vinous 

 red shade through the lower half of the wing, less marked in the basal 

 and terminal spaces. Basal line single, black, strongly dentate, run- 

 mng to the basal dash. T. a. line single, broader on costa and internal 

 margin, strongly dentate between veins, slightly oblique outwardly. 

 T. p. line broad, distinct, crenulate, outwardly curved over reniform, 

 and inwardly sinuate below, the curves very even and not strong. A 

 broad, diffuse median shade crosses the reniform, then runs parallel
