1933] New Psammocharidae from the United States 7 
Psammochares catalinae sp. nov. 
$ Black throughout, head and thorax, pleura, propodeum 
with front coxse hairy ; not quite as much so as in P. sceles- 
tus, the femora not hairy, or with a few fine hairs, the mid 
and hind femora on apical part with distinct short spines 
rising from pits (these not in scelestus.) Face narrower 
than in P. scelestus , plainly narrowed above ; the ocelli in a 
more nearly equilateral triangle, the posteriors only a little 
nearer to each other than to eyes; third joint of antennse 
one and a third as long as the fourth; pronotum strongly 
angulate behind as in P. scelestus ; propodeum sloping as in 
P. scelestus , not quite as much arched, a distinct median line 
on basal part; abdomen with a few hairs on base of first 
segment, and on tip and along venter. Legs of moderate 
length, with only a few extremely fine short hairs; front 
basitarsus with but three comb-spines, no shorter spine be- 
fore them; inner spur of the hind tibia a little more than 
one-half of basitarsus. Wings with venation about same as 
in P. scelestus, second and third submarginal usually a little 
shorter in proportion and subequal in length. The male is 
very similar, but much more slender ; the ventral plate has 
a very prominent median carina on the basal part, no hair- 
tufts ; tip of abdomen is somewhat silvery in certain lights. 
Length 9-10 mm., fore wing 8 mm., male 8 mm.

only three comb-spines on front basitarsus, less hairy body, 
and by the minute spines above on mid and hind femora.
