followed by a narrow pale shading, rather abruptly bent over the cell, then evenly 

 oblique to the inner margin. S. t. line pale, irregular, broken, almost punctiform. 

 Median shade marked by a black spot on the costa, thence oblique between the ordi- 

 nary spots almost to the t. p. line ; then parallel with this line and close to it to the 

 inner margin ; nowhere well-marked except on the costa. The outer margin is 

 .slightly scalloped and emphasized by a narrow, dark, terminal line, followed by a 

 narrow pale line at the base of the fringes. The latter have a dusky interline and 

 are incompletely cut opposite the interspaces. Claviform wanting. Orbicular round, 

 rather large in size, paler than the ground, not defined. Reniform moderate in size, 

 broad, upright, paler than the ground, not outlined and incompletely defined. Sec- 

 ondaries whitish, somewhat translucent, with a broad smoky outer border. A pale 

 yellow, followed by a smoky line at the base of the fringes. Beneath whitish, smoky 

 toward the outer margin, the maculation of the upper side faintly reproduced. Breast 

 and base of legs with a pinkish tinge, the tarsi pale ringed. Expands 1. 20 inches 

 = 30 mm. 



Habitat : Colorado desert, Hy. Edwards ; southern Arizona, April 

 1-15, Poling. 



Two males : one is an old specimen given me many years ago by 

 the late Henry Edwards. I recognized it as distinct from the de- 

 scribed species, but realized also that it must be a discolored example ; 

 so I held it until I received recently from Dr. Barnes a fresh male 

 which belongs obviously to the same species. The rosy flush over the 

 thorax and basal space, and the broad, velvety, somewhat diffuse t. a. 

 line serve to differentiate the species at once. It is allied to refecta 

 in the simplicity of the basal line. 

 Oncocnemis simplicia, sp. nov. 



Primaries dull luteous gray, powdery and obscurely strigate so as to give a sordid 

 confused appearance. Head deep chestnut brown. Basal line single, black, oblique, 

 connected with the t. a. line by a narrow blackish streak. T. a. line single, black, 

 broad, oblique. T. p. line marked by a smoky costal spot over the reniform, then 

 almost lost as it bends over the cell ; reappearing below vein two as a single black 

 line, a little incurved and forming a slight outward dent on vein I. S. t. line a vague, 

 irregular palershading, and thereisa seriesof black venular dots on the slightlyscalloped 

 outer margin. Orbicular concolorous, oval, decumbent, narrowly pale ringed. Reni- 

 form narrow, almost lunate, pale ringed, the annulus edged with somewhat darker 

 scales ; center a little darker than ground. Secondaries translucent, white with a 

 slight yellowish tinge, tending to smoky at the margin. Beneath yellowish-white, 

 powdery along the costa and apically, both wings with a broken outer line ; primaries 

 with a small discal spot. Expands 1.28 inches := 32 mm. 



Habitat : Colorado desert. 



One male in fair condition. This is another of those specimens 

 that has rested, undescribed, in my collection for many years, await- 

 ing a companion of the other sex. I suspected a possible connection
