REVISION OF SPECIES OF THE GENUS AGKOTIS. 197 



iforin. (Jell black, <lefni in jj the ordinary spots ; orbicuhir variable in 

 size and shape, usually round, coucolorous, powdered with gray, or 

 entirely pale ; rarely iuconiplete; reuiform always distinct, complete, 

 larjje, outlined by a black line annulate with yellowish, ceutrally 

 clouded with dusky. Transverse lines oiten obsolete; when present, 

 t. a. upright, sinuate, not crossing pale <;ostal space; geminate; t. p. 

 illy marked, soniewdiat extended on the veins, parallel with outer mar- 

 gin. iS. t. line pale, marked on costa and below vein (> by a [)receding 

 dusky shade. Secondaries dull fuscous. Beneath variable, powdery, 

 with distinct discal spots. Read and thorax coucolorous, collar with a 

 dark line; thorax with low anterior and posterior divided tufts. 



Expands 37-40""" ; l.o-l.O inches. 



IIabitat.— Canada, Northern and Eastern States, Michigan, Mis- 

 souri, Colorado. 



A very distinctly marked and easily recognized species. The syn- 

 onomy was caused in i)art by some confusion of identification between 

 Mr. Grote an«l Mr. Morrison. Mr. Morrison's type is a very pale form 

 in which the ordinary spots are gray. He did not recognize the type 

 form of tiirrifi as being the same species, and hence, apparently, Mr. 

 Grote's error. (See Can. Ent., 7, 220.) 



I have no doubt of the correctness of this identification of Guenee's 

 species. 



Carneades idahoensis Grt. 



1878. Grt., Bull. Gcol. Siirv., iv, 171, Agrotis. 



Fuscous red brown, the costa broadly gray, as are also the ordinary 

 spots. A distinct basal dash black; cell black; clavi form narrowly 

 outlined in black. Transverse lines obsolete, very faintly traceable. 

 S. t. line pale, irregularly dentate, often barely visible. Orbicular 

 oblicpie, oblong, open superiorly; renilbrm modemte, kidney-shaped. 

 Secondaries pale fuscous. Beneath powdery, pale ; an exterior com- 

 nu)n line and discal lunule, darker. Head and thorax coucolorous; 

 collar with a black line. 



Expands 32-3ii""" ; 1.30-1.45 inches. 



flAUiTAT. — Idaho, Colorado, Nevada. 



A very easily recognizable species; very distinct from anything else 

 in the group, except, i)erhaps, wcstennani and fiirtivus, from each of 

 which it has been already sullicienrly distinguished. It bears a more 

 than casual resemblance to some of the forms referred to the quad- 

 ridentata group of the genus. 



Carneades furtivus Smith. 



1890. Siiiifh. Trans. Am. Ent. Soc. xvii, 50, Agrotis. 

 Ground color varying from fust^ous gray to bright red brown. Head 

 and thorax evenly coucolorous, collar with a central black, transverse 

 line. Primaries with costal space to t. p. line pale, discolorous, in the
