dull, without distinct punctures; area of metathorax dull, defined 
by absence of hair; hair at sides of metathorax very long and 
curled; legs with pale hair, largely chocolate on outer side of middle 
and hind tibia, pale orange on inner side of basitarsi; spurs pallid; 
tegule black; wings slightly dusky, stigma ferruginous, nervures 
fuscous; b. n. meeting t. m.; first r. n. joining second s. m. about 
middle; abdomen broad, with a completely dull impunctate sur- 
face; first segment with long fulvous hair at base, and a patch on 
each side on hind margin; segments 3 to 5 with conspicuous entire 
fulvous hair-bands; apex with pale soot-colored hair, a sort of 
reddish-gray; second segment depressed about a third, but the de- 
pression obscure. 
Habitat: Claremont, California (Baker; Pomona coll. 197). 
Resembles 4. auricoma, but very distinct by the opaque abdomen. 
Andrena chlorura sp. n. 
@ Length nearly 8 mm.; olive green, the metathorax, legs and 
antenne black; pubescence fulvous, bright fox-red on thorax above 
and tubercles; some thin black hair on front and vertex; process of 
labrum very broad and rounded; clypeus with sparse weak punct- 
ures; facial fovee black, rather narrow, ending below at level of 
antenne; third antennal joint longer than next two together, but 
not so long as next three; mesothorax dull, impunctate; area of 
metathorax dull; tegule piceous; wings dusky; stigma large, dark 
reddish; nervures fuscous; abdomen shining, impunctate, with thin 
narrow fulvous hair-bands on segments 2 to 4, but none on first; 
hair at apex black; second segment depressed about a third in 
middle, but very narrowly at sides. 
Habitat: Mountains near Claremont, California (Baker; 
Pomona coll. 197). A pretty species, known among the green 
Andrene by its red hair and small size. In Viereck’s tables of 
Andrena of the N. W. States it runs near to 4. chlorinella Vier., 
from which it is quite distinct. According to Viereck (litt. 1907) 
A. xanthostigma Vier. is identical with chlorinella. 
Diandrena beatula sp. n.
