legs pubescent, that on edge of anterior tarsi and' apical 

 portion of tibiae shiny golden brown ; wings dusky hyaline, 

 clouded beyond nervures, nervures and stigma piceous ; tegulse 

 piceous, very shiny ; abdomen bare save for scettered hairs 

 laterally and fringe on last two segments ; closely and finely 

 punctured from apical half of first segment to apex, basal 

 half of first segment very smooth and shiny. Length about

Hah. MesiUa, N. M., April 13, 1895, on lilac [Casad, 195).

In its general build and the black pubescence this closely 

 resembles A. prima. The first joint of the flagellum is 

 longer than the two following together ; it is not so long as 

 this in prima. The metathorax is minutely granular, with 

 shallow punctures except on the enclosure, which is not 

 bounded by a salient rim. In prima the enclosure is quite 

 different, being strongly wrinkled. The wings are not so 

 dark as in prima. 



h. Pubescence grey, white, or fulvous. 

 a. Stigma ferruginous and apex of wings dusky. 



Andrena fracta, Casad & Ckll., sp. n. 



^ . " Black, head as wide as thorax, densely pubescent ; 

 clypeus yellow, circular, but thinly pubescent, with a black 

 dot on each side halfway between upper and lower edges ; a 

 heavy fringe below clypeus, across lower edge of face ; pubes- 

 cence below antenna, and on cheeks pale, that above antennae 

 and on occiput ochraceous ; thorax above clothed with 

 ochraceous hairs, those on scutellura and postscutellum 

 densest, those on metathorax and pleura pale. Legs black, 

 femora and coxae with pale hairs, those on tibiae, tarsi, and 

 apices of femora ochraceous ; wings smoky hyaline, darkest 

 beyond marginal cell and in second and third submarginals, 

 in places stained with yellow ; abdomen closely punctured, 

 clothed with very fine short appressed hairs, which become 

 ochraceous on fourth segment, and are sufficiently heavy on 

 apical margins of segments 4 and 5 to form bands ; apex 

 quite heavily fringed with ochraceous. Length about 

 11 millim." [Jessie E. Casad.) 



Small examples are only about 8^ millim. long. The 

 antennae are quite long, wholly black.
