cross-veins and gradates, longitudinal veins pale, without dark dots ; 
in hind wings the dark less distinct; stigma somewhat infuscate, but 
the cross-veins not bordered. Tip of hind wing pointed, that of the 
fore wing more broadly rounded; venation very similar to the other 
species ; the costal area rather narrow near base ; three inner and 
four outer gradates. Hairs on veins about as in allied species. The 
divisory cell is shaped much as in Nodita, with a broad, oblique base. 
The process at tip of abdomen is shorter than in the other species, 
and projects only a little; it is densely long-haired and I see no 
reclinate bristles, but there are raised conical processes tipped with 
a stiff hair (best seen on lower edge). The elliptical pale lobe on 
side of last segment is larger than in the other forms. Length of fore 
wing, 10 mm.; width, 3 mm. 
One male from Grand Canyon, Arizona, 24 July.

Eremochrysa tibialis sp. nov. 
Head, thorax, legs whitish; face with a reddish mark each side, 
divided inwardly ; the upper, narrow part borders the antennal 
socket, the lower and broader reaching nearly to middle of face; 
clypeus with a dark median spot near lower edge, and a larger 
black spot at upper corner of clypeus, and extending a bit onto 
clypeus; cheek with a broad, dark brown (or rich brown) stripe, 
reaching to upper edge of clypeus ; palpi dark, except tips of the 
joints. The basal antennal joint has a short black line or spot 
toward the inner tip; a black line on outer side and one above, and 
the second antennal joint dark (rich brown). The vertex has a dark 
spot each side on the raised area, with a short line extending for- 
ward, and a long dark spot close to the posterior part of eye; the 
collar (below the front of pronotum), has two dark brown marks on 
outer side. 
The pronotum has a dark margin (formed of dark lines), broken 
near middle; there is a dark dot near the middle of front margin, 
another at middle before the cross-groove, and two behind the 
groove. The lateral lobes of meso- and metanotum have dark spots, 
and one on each lateral corner of the mid-lobe of mesonotum. Legs 
pale, all the tibiae have a dark dot near base, and a dark cross-line 
about one-third way down; the hind femur has a small dark spot 
near end. 
The abdomen above is dull yellowish, with narrow dark hind
