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 Cryptauthc 

 {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 A. mimetica falli 

 CklL, and at Claremont A. pniuorum gillettei Ckll. 



Andrcua priinonim var. niariformis v. n. 



9 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 ciiscal patch. 



Habitat: Claremont, California {Baker; Pomona coll. 207). 

 This is not stylopized. Can it be a partial gynandromorph? All 

 the characters, including the antennae, are those of a female, except 

 the clypeus. 



Audrena pcratra sp. n. 

 2 Tength about 10.5 mm.; entirely black, with black hair, ex- 

 cept perhaps partly on mesothorax, which is denucied in type; heaci 

 very broad, facial quadrangle very much broader than long; malar 

 space very short; process of labrum obtusely pointed; clypeus cieli- 

 cately roughened, with rather close weak punctures, no smooth 

 line; front minutely striate; facial foves dark seal brown, occupying 

 more than half the distance between antenuce and eye, ending below, 

 far below level of antennas; third antennal joint considerably lon- 

 ger than next two combineci; flagellum obscure redciish beneath ex- 

 cept at base; mesothorax dull, granular, with no ciistinct punctures; 

 area of metathorax granular; pleura with long reddish-black hair; 

 small joints of tarsi reddish; tegula? 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
