Psyche 
[June 
beyond dark at one end ; gradates green. Cheeks with a narrow 
black line, interrupted near middle; palpi with a narrow black line 
above on one or two joints; in the male these lines more prominent, 
and the basal joint of antennae pale, with a reddish mark in front 
toward the tip, the basal joint extends laterally over the eye; the 
upper edge, seen from in front very concave; the second joint is 
much longer than broad, constricted below the middle, the lower part 
bearing minute erect hairs. The third joint is elongate, swollen 
mostly toward the inner base, the outer edge there concave, the 
inner edge has the row of white curved hairs which extends, some- 
what obliquely upward. The interantennal process is much broader 
than long, concave in front (seen from above) each side at tip ex- 
tending somewhat laterally and tipped by some short bristles. On 
the front, just before the anterior slope, is a group of erect hairs, 
pointing toward the process. 
The wings are more slender than in M. emuncta, the tip almost 
in a point. The hairs on the costal fringe are very much shorter 
than in M. emuncta, and those elsewhere on the venation are much 
fewer. In the fore wing about twenty-four costals before stigma, 
the cells, except toward stigma, are plainly higher than broad; the 
costal area (at widest) hardly equal the radial area; the divisory cell 
two and a half times as long as broad, ending beyond cross-vein 
above ; below there are seven cubital cross-veins. The hind mar- 
ginal area is one and one-half times as broad as the cubital, but not 
quite twice as broad as costal area. Seven to nine inner gradates 
and eight to ten outer ones, in parallel rows ; each gradate separated 
about its length from the next. In hind wings eight gradates in 
each row, about parallel. Beyond the end of medius (fore wing) 
there are five or six forks before wing tip. Length of fore wing, 
14.5 mm.; width, 5 mm. 
Male and female from Upper Santa Ana River, San Bernardino 
Co., California, 15 July, 6 Aug., 1948. (G. H. and J. L. Sperry). 
Also an old female from San Bernardino Mts., South Fork, 20 June, 
6000 ft. (Grinnell).

Meleoma cavifrons sp. nov. 
A small, slender-winged species, with few cross-veins, basal joint 
of antennae erect, and, seen from in front, each side convex, the
