gins; stigma narrowly lanceolate, very slender, ferruginous with 
dark margin; b. n. meeting t. m.; first r. n. joining second s. m. much 
before middle; second abdominal segment depressed less than a 
third; venter purplish. 
Habitat: Claremont, California, at flowers of Cryptanthe 
(Baker; Pomona coll. 198). Easily known among the species with 
green abdomen by its large size, abundant long pale hair, and very 
slender stigma. 
In the mountains near Claremont Baker took 4. mimetica falli 
Ckll., and at Claremont 4. prunorum gillettei Ckll. 
Andrena prunorum var. mariformis v. n. 
?  Clypeus pale yellow with two black spots, exactly like that 
of a male. The hair on head and thorax above is fine fox-red; the 
abdominal hair-bands are pale fulvous. Scape partly red, especially 
at apex; flagellum wholly dark. Second abdominal segment with a 
large black discal patch. 
Habitat: Claremont, California (Baker; Pomona coll. 207). 
This is not stylopized. Can it be a partial gynandromorph? All 
the characters, including the antenna, are those of a female, except 
the clypeus. 
Andrena peratra sp. n. 
? Length about 10.5 mm.; entirely black, with black hair, ex- 
cept perhaps partly on mesothorax, which is denuded in type; head 
very broad, facial quadrangle very much broader than long; malar 
space very short; process of labrum obtusely pointed; clypeus deli- 
cately roughened, with rather close weak punctures, no smooth 
line; front minutely striate; facial fovee dark seal brown, occupying 
more than half the distance between antenne and eye, ending below, 
far below level of antenne; third antennal joint considerably lon- 
ger than next two combined; flagellum obscure reddish beneath ex- 
cept at base; mesothorax dull, granular, with no distinct punctures; 
area of metathorax granular; pleura with long reddish-black hair; 
small joints of tarsi reddish; tegule piceous, largely ferruginous 
posteriorly; wings translucent reddish, not dark; stigma ferruginous, 
narrowly lanceolate, extremely slender; nervures fuscous; abdomen 
granular, without evident punctures, but moderately shining; second
