marginal area scarcely more narrow than the cubital, six radial 
cross-veins, four outer gradates, these close to wing-tip; no inner 
gradates. Cross-veins wholly dark brown, longitudinals pale, un- 
marked except at joinings. Three stigmal cross-veins dark, but 
scarcely bordered; hind wings also with the cross-veins dark, and 
the longitudinal pale, except at joinings. 
A female is similar, but the mark below antennae does not occupy 
the whole area; pronotum as broad as long. Length fore wings, 
male 6.5 mm. ; female 8 mm. 
One male and several females from Stockton Pass, Pinaleno Mts., 
Graham Co., Arizona, 5440 ft. (Nutting and Werner). 
Type: M. C. Z. no. 28357. 
Eremochrysa rufifrons sp. nov. 
Face whitish or pale yellowish, usually the three clypeal dark 
spots and a slender cheek-mark; basal antennal joint with an outer 
black stripe, and one on the inner side, none above, second joint 
of antennae more or less darkened; palpi mostly black, with more 
or less distinct pale bands; vertex more or less rufous in front, 
shining. Legs pale, hind femur with a dark mark near tip. 
Pronotum usually a little longer than broad and tapering slightly 
in front; pale, dull yellowish, no marks on side nor band across, bpt 
in front are two small dark spots, sometimes faint. Meso- and 
metanotum and pleurae also pale yellowish, without marks. Ab- 
domen also pale, unmarked. Hairs on pronotum dark, those on 
abdomen mostly pale, but in females there are some black bristles 
on the dorsum of some segments near tip of abdomen; in the male 
the hair on abdomen is white and very short. 
Fore wings with cross-veins wholly dark, some toward base are 
often more broadly dark; the longitudinal veins are pale, except at 
endings of the cross-veins, no dots. Stigma but little darkened, and 
the three cross-veins not strongly marked. The wings are not 
broadened before tip as much as in E. fraterna, there being but two 
or three branches of radial sector to reach the outer border. 
Twelve or thirteen costals, six or seven radials, two or three inner 
gradates and three or four outer ones. The divisory cell is slender 
and ends well beyond the cross-vein above, six cubital cross-veins 
beyond. In the hind wing the median and cubitus are united for a 
long distance near base; no inner gradates. Length of fore wing, 
8 mm.
