may be of some value. Unfortunately our series are too small to 

 allow proper investigation of this feature in the two species. 

 The life history is unknown.

fig. 1. 



Head brown, tawny-white between antennae. Antennae with a row of 

 variably heavy brown dots above. Palpi moderate, slender, whitish. Fore and 

 middle legs white with brown lines, continued onto first joint of tarsi ; tarsi 

 also shaded with brown. Hind legs light brownish, tarsi slightly paler. Spurs 

 rather long. Thorax and abdomen tawny, the latter with some single dorsal 

 brown dots in posterior margins of segments, otherwise immaculate. 



Primaries even ochreous-tawny. Cell with a brown dot near middle and 

 cleft preceded by a heavy but not large brown spot, from which a few scales 

 sometimes extend to embrace the extreme base of the cleft. Costa without a 

 patch over base of cleft, but sometimes with its position indicated by two pale 

 areas. First lobe with two brown dots on costa, one near middle, sometimes 

 absent, and one beyond, a more elongate spot at apex and a heavier one before 

 apex on inner margin. Second lobe sometimes with a few dark scales at tips 

 of veins. There are a few scattered brown scales on the wing, chiefly along 

 tl'.e inner margin near the base. Fringes grayish tawny with a dark brownish 

 gray patch preceding apex of first lobe with a few pale hairs at the marginal 

 dot, and a similar but paler and less conspicuous dark region at apex of second 

 lobe. Secondaries gray-brown, their fringes a little more tawny. Expanse 

 20-22.5 mm. 



Described from five specimens, of wliich we have made four types as 

 follows : 



Holotype 9, Stockton, Utah, July 30 (Spalding) allot\pe and one para- 

 type 9, Provo, Utah, Aug. 12 (Spalding) in coll. Barnes. 



Paratvpe 9, Beulah, N. M., 8000 it.. July (Cockerell) U. S. N. M, No. 

 23479. 



.Ires is closely related to cochisc but is much more evenly colored 

 and has less blackish-brown irroration. The absence of the costal 

 dash over the base of the cleft appears to be constant, and is in itself 

 enough to distinguish the species.
