NEW AND LITTLE-KNOWN BEES. 157 
of metathorax granular, poorly defined; tegule piceous, minutely 
roughened; wings dusky, the apex broadly fuliginous; stigma well 
developed, bright orange-fulvous; nervures fuscous; second s.m. 
broad, receiving first r.n. beyond beginning of last third; legs black, 
with pale hair, that on inner side of tarsi black or very dark fuscous ; 
hind tibial scopa sparingly plumose, the hairs straight; middle and 
hind basitarsi broad; surface of abdomen black, minutely roughened, 
without evident punctures; hair in the regions between the pale 
bands wholly pale. 
Hab.— Boulder, Colorado, October 4th, 1915 (Cockerell). 
Visits Composite, as shown by the abundant bright yellow 
pollen carried. Related to A. asteris, Rob., but easily separated 
by the dark apices of wings and broad, dense, abdominal bands. 
There is a strong superficial resemblance to A. colletina, Ckll. 
Chelostoma rubifloris edwardstt, subsp. n. 
@. Length about 6 mm.; mandibles long, strongly bidentate at 
apex; second recurrent nervure joining second submarginal cell a 
considerable distance (about equal to length of vertical portion of 
outer transverso-cubital nervure) from apex. 
Hab.—Amador County, California (H. Edwards). British 
Museum. Readily known from C. rubifloris (Ckll.) by its small 
size, but in other respects so similar that it can hardly rank as a 
distinct species. 
Coelioxys genalis, sp. n. 
3. Length about 75 mm.; black, coarsely punctured; head 
broad; eyes with abundant yellowish hair; face densely covered 
with pale tan-coloured hair, and on sides of front it is even paler ; 
vertex dull, with very large, irregular punctures, the region on each 
side of ocelli nearly impunctate, except that it is crossed by a line of 
large punctures; upper part of cheeks with an elongate-subquadrate 
patch of pale tan hair, but below this and separated from it is a 
broad, bevelled or grooved band along posterior orbits, densely filled 
with felt-like hair, which appears pure white at one angle and pale 
tan-colour at another; mesothorax with very large punctures, more 
or less in rows, the disc between the punctures moderately shining ; 
scutellum with larger punctures than those of mesothorax, the 
posterior margin broadly rounded (faintly subangulate), the basal 
margin with two small spots of white hair; axillar spines short ; 
tegulee piceous with a dark rufous spot; wings with the apical half 
deep fuliginous, the basal hyaline; legs black, inner side of tarsi 
with fulvous hair; abdomen shining, polished, with large punctures, 
on fourth segment smaller basally; hind margins of segments with 
narrow white hair-bands, linear and weak in middle; fifth segment 
with a dentiform tubercle on each side; sixth with six sharp spines, 
the lateral nearly as long as the upper apical, lower apical longest ; 
anterior coxee with rather short spines. 
Hab.—Mt. Makiling, Luzon, Philippine Is. (Baker, 5242).
