whitish witli a double outward dusky shade, aud a dusky discal spot. 

 Beueath whitish, powdery, each wiu^ witli a faint discal spot aud in- 

 complete common line. Head and thorax concolorous. Thoracic vesti- 

 ture, hairy. 



Expands 29-37""'>; 1.15-1.50 inches. 



Haeitat. — East of Eocky Mountains. 



A very variable species in the shade with which the gray ground 

 color is sufl'used. A remarkably large and handsome specimen from 

 Utah is shaded with a rich carmine. Eastern specimens are, as a rule, 

 smaller and more yellow in color than western examples. Mr. Grote 

 has made very persistent efforts to get this species into the synonomy 

 somewhere, but without any remarkable amount of success heretofore. 



The early stages have been described by Professor Riley. 



Carneades choris Harv. 



1876. Harv., Can. Eut., viii, 37, Agroiis. 



Grayish fuscous; rather evenly sprinkled with dark scales, the tint 

 very even and smooth in appearance ; veins marked. Transverse lines 

 rather broad, distinct, geminate, the included space i^aler. T. a. line 

 outwardly oblique, very slightly wavy ; t. p. line parallel with outer 

 margin, rather even ; s. t. line, narrow, i)ale, interrupted, its course 

 sinuate. Claviform outlined. Ordinary spots distinct; orbicular 

 round, moderate ; reniform well sized, inferiorly somewhat enlarged. 

 Secondaries whitish with dusky external line. Beneath w^hitish, pow- 

 dered with gray, a distinct discal lunule ; primaries with a dusky trans- 

 verse line. 



Expands 35-37"'"' ; 1.40( 9 )-1.50( $ ) inches. 



Habitat. — Colorado, Nevada. 



There is considerable difference between the sexes of this species ; 

 the $ is paler, the transverse lines unusually approximate ; s. t. line 

 subobsolete ; ordinary spots paler ; the 9 is darker, the transverse lines 

 normally separated; s. t. line distinct, ordinary spots annulate with 

 pale, else concolorous. This is a perfectly distinct and well-marked 

 si)ecies, entirely unlike any other described form. 



The specimens before me do not quite agree with what Dr. Harvey 

 says of the species. His type is a 5 , and, compared with the example 

 before me, the latter has the t. p. line more evidently marked and the 

 orbicular is hardly elongate, nor the reniform narrow. Still I do not 

 think I have a distinct species.
