fourth and fifth segments with large triangular elevated areas, 
which are rather sparsely punctured; fifth segment with a small 
tooth on each side; sixth with dense white hair at base, at each side 
a long sharp tooth, the apical lobes far apart, each with two teeth, 
the upper short, little more than a salient angle, the lower long, 
flattened, rounded at end, divergent; fourth ventral segment not 
emarginate. 
Habitat: Claremont, California (Baker; Pomona coll. 195). 
I wondered whether this could be the undescribed male of C. coquil- 
letti Crawf., but it is larger than the male of that species would 
probably be, there are no hair bands bounding mesothorax or scutel- 
lum posteriorly, the vertex is not entirely rugose, and the abdomen 
is without red. From C. novomexicana it is easily known by the 
hair on eyes being more than twice as long. By the long hair on 
the eyes it resembles C. ribis kincaidii Ckll., which has black legs, 
and the apical teeth of abdomen closer together and almost parallel. 
Coelioxys angulifera sp. n. 
@ Length about 11.5 mm.; black, strongly punctured, with 
white hair; lower margin of clypeus angularly produced and sloping 
a little outward; knees, tibiae and tarsi dark red, the tibia with a 
strong blackish suffusion. Very close to C. banksi Crawf. (from 
Virginia), differing thus: teeth at sides of scutellum long; no band 
of white hair in scutello-mesothoracic suture; mesopleure with 
long hair (not very dense) all over; last ventral segment not so 
much extended beyond last dorsal. Except for the clypeus, it much 
resembles C. moesta Cress., differing in the much longer teeth at 
sides of scutellum, and much larger punctures at base of penultimate 
ventral segment. 
dé Length about 8 mm.; face and front densely covered with 
white hair; anterior coxe with well-developed spines; legs darker, 
the tibia mainly blackish; fifth abdominal segment with a short 
spine on each side; sixth with a long spine on each side, and the apical 
lobes each with two spines, the upper much shorter than the lower; 
no median spine; fourth ventral segment entire. In my table of 
male Coelioxys (Canad. Entom., 1912, p. 170) this runs to C. 
angelica Ckll., the female of which is very different from C. anguli- 
fera.
