neath vein one making a louger outward reach, greatly contracting the 

 median space. T. p. line strongly dentate, its course nearly parallel to 

 the outer margin. S. t. line obsolete; claviforni wanting; orbicular 

 obsolete, or very faintly defined; reniform dusky, indefinite, lunate. 

 Secondaries smoky fuscous, somewhat paler at base. A distinct discal 

 lunule. Beneath dusky, secondaries paler, powdery ; a distinct com-

Expands 34-36""" ; 1.35-1.45 inches. 



Habitat. — Canada, New York, Massachusetts, Maine, District of Co- 

 lumbia, Northern, Middle, and Eastern States. 



Very distinct by the dark ash-gray color and the blackish single very 

 irregular transverse lines. The species is found not commonly through- 

 out the Middle and Eastern States, westward to the Mississi])pi. 



The. reference of per mund a Morr. to this species is made on the faith 

 of a specimen so named in the Meske collection, and there is nothing 

 in the description which does not perfectly accord with this referenqe. 



Caineades perfusca Grt. 

 1883. Grt., Papilio, iii, 77, Agrotis. 



Uniformly dark fuscous, all the markings obsolete. Ordinary spots 

 concolorous, moderate; orbicular round, reniform wide; both marked 

 by whitisli scales. Secondaries yellowish fuscous. Beneath paler; sec- 

 ondaries with two shade bands and discal mark. Head and thorax con- 

 colorous. 



Expands 33""" ; 1.30 inches. 



Habitat — California, Colorado, Arizona. 



An obscurely marked species, comi)ared to messoria, but none of the 

 markings are evident. It is somewhat variable in color, the Colorado 

 specimen being rather more grayish. It has been sufiQciently dis- 

 tinguished from sponsa to which it is i)erhai)S most nearly allied. This 

 is sometimes a confusing species. The lines are occasionally somewhat 

 evident and the mcsnoria resemblance may become marked enough to 

 create doubt. 



Carneades pastoralis (lit.

 verse lines geminate; t. a. upright, but little curved between veins; 

 most distinctly so beneath vein 1; t. p. line very evenly curved, par- 

 allel with outer margin, slightly lunulate. S. t. line j)ale powdery, very 

 indistinct; sometimes marked by indistinctly darker sagittate marks. 

 Ordinary spots always defined, somewhat variable in size and shape; 

 narrowly outlined in black, then annulate with yellow ; the annuli vari- 

 ably distinct and sometimes consisting only of scattered scales; the 

 center is concolorous ; usually the spots are normal in size and shape,
