Oncocnemis euta, sj). nov. 



Ground color of head, thorax and primaries a pale chocolate brown. Head and 

 thorax concolorous, the vestiture scaly and in the specimens disarranged. Primaries 

 with all the maculation obscure, an oblique indelined paler shading through the 

 outer third of the wing relieving it from absolute uniformity. The basal and median 

 lines and the median shade are marked on the costa by spots or darker shades and 

 occasional black scales on the veins ; but no course can be made out. S. t. line 

 vaguely traceable as a zigzag pale line, emphasized here and there by obscure blackish 

 marks. A narrow blackish line at the base of the long fringes, which are cut on the 

 outer edge with darker brown. There is a very narrow, broken line from base, at the 

 end of which a claviform is indicated by black scales. Orbicular small, round, con- 

 colorous, outlined by black scales which incompletely define a slightly paler ring. 

 Reniform small, lunate, outlined and annulate in the same way. Secondaries yellow, 

 with a broad black margin taking up the outer third of the wing. Fringes yellowish 

 or brown. Beneath, both wings yellow with a broad marginal band, brown on the 

 primaries, black on the secondaries. Expands .88-1.00 inch 22-25 "^°^- 



Habitat: Utah." 



Two female specimens in good condition save that the thoracic 

 vestitute is disarranged and partly lost. The resemblance is to mirifi- 

 calis, but this is a smaller species, with lighter primaries on which the 

 maculation is barely traceable. Unfortunately I ha\e no better data 

 as to locality than above given, and none as to date or the collector of 

 the specimens. 

 Oncocnemis chorda Grt. 



This was described as an Homohadena and, when I revised that 

 genus in 1890, I had, apparently, a specimen from the Edwards col- 

 lection before me. Whether that specimen was imperfect or whether 

 I simply accepted the generic reference as correct, I cannot say now ; 

 but in I goo the type in the British Museum seemed familiar, and on 

 examination I recognized it as my Oncocnemis refecta. The type 

 shows the generic characters clearly and my examples came from the 

 type locality ; resembling the original specimen much more nearly 

 than does the Edwards specimen, which is from Sierra Nevada. 

 Oncocnemis rosea, sp. nov.. 



tiround color yellowish-gray. Head and thorax with a rosy red suft'usion which 

 fades out in old specimens and leaves the pale luteous ground with an odd discolora- 

 tion that is recognizable when a fresh specimen comes to hand. Head with a dusky 

 line across the front. Primaries with a rosy tinge in the basal space which changes 

 beyond the t. a. line to a gray which, in the s. t. space becomes blackish or smoky 

 and darkens the outer portion of the wing. Basal line single, blackish-brown, nar- 

 row, well-marked. T. a. line single, broad, a little diffuse, velvety blackish-brown, 

 a little outcurved. T. p. line lunulate, single, blackish on costa, else smoky, slender,
