female, is somewhat contrasting. Beneath whitish, powdery, disk of 

 primaries smoky, dai'ker iu the female; no outer line; but a discal spot 

 on all wings. 



Expanse, 40 mm. (male) to 42 mm. (female) = 1.60 to 1.68 inches. 



Habitat. — Colorado (Bruce) ; Hall Valley, August (Barnes). 



One male (Bruce) has been in my collection for years; the female has 

 been recently received from Dr. Barnes. The species is much more 

 obscure througliout than messoria, and the hairy vestiture throws it 

 rather to the bostoniensis series, where it does not conflict with any 

 described species. 



A third specimen, also from Colorado, near Denver, I refer doubtfully 

 to this species. It expands only 35 mm., is more sharply marked 

 throughout, and the sub terminal space is uniformly darker, relieving a 

 subterminal line which is distinctly toothed on veins 3 and 4. The sec- 

 ondaries are also more whitish and the smoky outer border is better 

 defined. 



23. CARNEADES RELAXUS, new species. 



Ground color pale, smoky fuscous, with a slightly reddish tint. 

 Head and thorax concolorous. Palpi tij)ped with yellowish, dusky at 

 the sides. Collar with an incomplete brown line near the tip. Tho- 

 racic vestiture of flattened hair, patagia hardly relieved, tuftings just 

 indicated. Primaries without contrasts, the lines smoky rather than 

 blackish. Basal line geminate, indicated on the costa and submedian 

 interspace only. Transverse anterior line geminate, inner line marked 

 on costa only, outer a little oblique and feebly outcurved in the inter- 

 spaces. Transverse posterior line geminate, outer line lost below the 

 cell, inner crenulated, as a whole outcurved over cell, and then almost 

 parallel with the outer margin. Subterminal line pale, irregular, with 

 small teeth on veins 3 and 4, relieved by a continuous, dusky, preced- 

 ing shade, the terminal space being also more or less dusky. A series 

 of brown, terminal lunules. Median shade vague, diffuse, barely 

 traceable. Olaviform absent in the specimens before me, but I should 

 expect to find indications of it in the species. Orbicular round or oval, 

 outlined by black or smoky scales, concolorous, center with or without 

 dusky powderings. Reniform large, kidney- shaped, extending a little 

 below the cell, outlined by black scales, center more or less dusky 

 inferiorly. Secondaries very pale yellowish, becoming smoky out- 

 wardly; fringes whitish, discal lunule present. Beneath whitish, 

 powdery, a more or less obvious common outer line, and all wings with 

 discal spots. 



Expanse, 38 mm. (male) to 39 mm. (female)^ 1.52 to 1.56 inches. 



Habitat. — San Francisco and Sierra Nevada, California. 



One. male and one female, and there is just a little doubt as to their 

 really being sexes of the same species; line for line they are the same, 

 and such little differences as occur are well within the range of varia-
