is also distinct and crossing, the renifonn is somewliat darker at that 

 point. Secondaries $ white, 9 bhick. Beneath pale, powdered with

Easily recognized by the almost uniform dark ash-gray color. The 

 diiference in color of secondaries in the sexes is unusnal, and not par- 

 alleled to the same extent in the genns. The vestiture is woolly, long.

Gra}', suffused with reddish; the ordinary spots concolorous, very illy 

 defined. Transverse lines usually obsolete ; in pale specimens distinct, 

 redbrown, single. T. a. line upright, with an outward curve below

 accompanied by a darker reddish shade. The median lines marked at

Habitat.— Colorado. 



A very pretty and well-marked species : muscosa Grote, of which I 

 have the type, is based on a dark specimen in which only the median 

 shade line is distinct. It is a 9 , and in all the females the maculation 

 tends to become obsolete. 



Carneades medialis Smith. 

 1887. Smith, Proc. U. S. N.at. Mus., x, 459, Agrotis. 



Grayish white to ocher yellow, more or less irrorate with black 

 scales; the transverse lines diffuse, powdery, dark, geminate; s. t. line 

 also rather broad, diffuse; all the lines even ; ordinary spots dusky, not 

 defined, traceable; the usual median dark shade is distinct in most 

 specimens. Secondaries S white, 9 dusky; beneath white, sparsely 

 powdeftd with gray; ituletinite gray discal spots and common line. 



Expands 37-40'""; 1.5-l.G inches. 



Habitat. — Texas. 



Seems not uncommon in Texas and is a very distinct species. It was 

 in the Belfrage collection named muraemda, but is a very different 

 species. The $ specimens seem inclined to pale yellowish, giving the 

 insect a cursory resemblance to citricolor, than which it is much larger.
