106 Psyche [March-June 
probably not an Arachnophila , for nothing is said about hair on 
abdomen and femora and the third submarginal cell is far from 
being triangular. 
Ageniella pallida sp. nov. 
Pale yellowish to pale rufous throughout, the only dark mark 
is the extreme base of the petiole; legs pale yellowish, also basal 
part of antennae (rest broken), body slightly sericeous on coxae 
and pleura. Wings hyaline, veins and stigma pale yellowish. 
Very little hair on body, a few fairly distinct at tip of abdomen. 
Clypeus nearly three times as broad as long, lower edge convex, 
few small hairs; face about as broad as high, not narrowed 
above, no distinct frontal groove; lateral ocelli very much 
closer to each other than to eyes; pronotum about as long above 
as in accepta , arcuate behind; propodeum plainly longer than 
broad, no median groove, seen from side evenly convex; petiole 
moderately long, abdomen much broader than propodeum; legs 
rather slender, hind femora reach tip of abdomen; mid and hind 
tibiae with a few short spines above, mostly in rows, inner spur 
of hind tibiae about one-third of basitarsus. 
In fore-wings the marginal cell is about its length from tip, 
upper and lower sides parallel for some distance, tip rather 
blunt, a little broader than second submarginal cell, latter small 
and little longer below than broad, narrowed nearly one-half 
above, receiving the first recurrent vein scarcely more than 
one-fourth from base; third submarginal cell almost twice as 
long below and fully twice as long above as the second cell, 
outer side scarcely oblique, but a little curved above, apex of 
cell only a trifle broader than base, receiving second recurrent 
vein just before middle; basal vein ends plainly before trans- 
verse; in hind wings the anal vein ends much before forking of 
cubitus, outer cross-vein much nearer base of radial sector than 
to tip. 
Length of fore-wing 5 mm., of body 7.5 mm. 
One female from Austin, Texas (Graenicher coll.). 
Type M. C. Z. No. 26738. 
Its generally pale color, the parallel-sided marginal cell, and 
the shape of third submarginal cell all separate it from our other 
species of the genus.
