Secondaries pale, outwardly dusky. Beneath pale; discal Innules 

 dusky, rather indefinite. Head and thorax concolorous ; collar with a 

 black baud. 



Expands 37'"'"; 1.5 inches. 



Habitat. — Maine. 



Easily distinguished by its incomplete markings. The type which is 

 before me is not fresh, and seems somewhat faded as well as a little 

 rubbed ; the lines are faintly traceable and are single ; fresh specimens 

 I thiok will have them fairly distinct.

Ash gray with faint lilac tinge ; median space more or less evidently 

 suffused with fuscous, forming an evident transverse shade line parallel 

 with and close to t. p. line; cell very distinctly black, relieving the 

 large concolorous ordinary si)ots. Transverse lines distinct, single; 

 t. a. line upright and nearly straight to vein 1, then widely bent out- 

 wardly to inner margin ; t. p. line evenly creuulate, parallel to outer 

 margin. S. t. line tolerably even, jireceded by a distinct dark shade. 

 Claviform outlined, sometimes sending a spur almost across the median 

 space. Reniform with a more or less evident dusky internal line. 

 Ordinary spots seldom completely outlined. Secondaries yellowish 

 fuscous. Beneath pale; a very distinct broad common line and kmate 

 discal spot. Head and thorax concolorous. 



Expands 34-37"""; 1.35-1.50 inches. 



Habitat. — Colorado, Nevada. 



This species, by the presence of a distinct transverse shade across 

 median space, conflicts somewhat with tlie diagnosis of the group ; 

 but the whole habitus and the distinct dark cell so evidently places it 

 here that we had rather make it exceptional than associate it with 

 species with which it otherwise bears no very close relationship. 



The type of sublatis, a S , is before me. Mr. Grote in his description 

 falls into the singular error of describing the antenna as simple. They 

 are very distinctly serrate — brush-like,- as Mr. Grote terms this struct- 

 ure. There is no doubt of the specific identity of the two forms.
