Psyche 
[March 
pronotum moderately long, angulate behind, not hairy; 
pleura and propodeum also without hair, propodeum rather 
short, at first nearly horizontal, then suddenly bending 
down, basal part smooth, but apical part very plainly finely 
striate, the striae strongest near tip. Abdomen with a few 
hairs near tip and on apical half of the venter. Legs of 
moderate length, spined about as in C. terminatus , inner 
spur of hind tibia short as in that species, some long hairs 
on front of front coxae. Wings also similar to C. terminatus, 
the marginal cell a little more pointed at tip, first recurrent 
ends beyond middle of second submarginal, second recur- 
rent at middle of third submarginal. 
A male is similar, with very long, slender antennae, the 
clypeus not excavate in front, the propodeum distinctly 
finely striate, and more toward base than in the female. The 
ventral plate is broad, with a median carina which on the 
basal part widens to a triangular area, not margined by : 
carinae, very similar to the plate of C. birkmanni. 
Length $ 13 mm., fore wing 10 mm. ; $ 10 mm. 
From Tempe, Arizona, 1 August (J. Bequaert). 
Readily separated from C. terminatus by the striate pos- 
terior part of propodeum. Type M.C.Z. 17035. 
Cryptocheilus attenuatus sp. nov. 
S Body and legs black, clothed with fine appressed pubes- 
cence, antennae beyond the second joint yellow, wings yel- 
lowish, tips broadly black. Face rather narrow, clypeus 
broad, truncate in front, vertex rounded from eye to eye, 
ocelli subequal, posteriors much nearer to each other than to 
eyes, vertex with a few erect hairs, thorax without long 
hairs; pronotum rather long, arcuate behind; propodeum 
rather long, evenly arched, sides parallel; abdomen elon- 
gate, slender, hairs only on the last segment, pygidium mar- 
gined on each side by a row of curved upturned hairs, and 
a median row of smaller hairs; ventral plate much longer 
than broad, tapering toward tip, with a faint median car- 
ina. Wings rather slender, marginal cell broadly rounded 
at tip, where it scarcely surpasses end of the third submar- 
ginal, being much more than its length from the tip of wing;
