no. 2064. BEES OF GENUS AND REN A— VIE RECK AND COCKERELL. 19 



A. paenenigra might be sought here, but is described below, as the 

 abdomen is hardly metallic; so also A. antonitonis, which has three 

 clear white hair bands. 



Type.— Cat. No. 18135, U.S.N.M.

ANDRENA VESTALI DOLICHOCERA, new variety. 



Sioux County, Nebraska. May. 



Male. — Length, 10 mm. Black, the small joints of tarsi dark 

 reddish. Clypeus, except lower margin and two spots, creamy white, 

 shining, with sparse feeble punctures. Pubescence very pale ochre- 

 ous white on vertex and mesothorax, but distinctly ocherous on 

 pleura, cheeks, face, and metathorax. Head broad; process of 

 labrum broad and low, truncate; sides of front dull and granular; 

 cheeks normal, rather shining; antennae rather short for a male, 

 flageUum obscure reddish brown beneath. Third antennal joint fully 

 twice as long as fourth; fourth broader than long, fifth about as broad 

 as long. Mesothorax dullish, well punctured; metathorax granular, 

 the area defined by an impressed line. Tegulae dark in front, red 

 behind. Wings hyaline, faintly brownish; stigma and nervures dark 

 reddish. Basal nervure meeting transverse median; first recurrent 

 nervure joining second submarginal beyond the beginning of its last 

 third; third submarginal cell long, spurs dark. Abdomen shining, 

 with only piliferous punctures, hoary with short pale hair, but no 

 bands; hind margins of segments broadly reddish; second segment 

 in middle depressed about one-third. Apical plate inversely heart 

 shaped, strongly emarginate. (This is clearly a variety of A. vestali 

 Cockerell, with pale hair and smoother abdomen.) 



o 20 . Clypeus yellow ; basal nervure going a little basad of transverse median ; flagellum 



red beneath. 

 a 21 . Flagellum short like that of a female. 



ANDRENA BERKELEYI, new species. 



Berkeley, Colorado. (Baker, 5833.) 



Male. — Length, 9 mm. Black, small joints of tarsi dull ferrugi- 

 nous. Clypeus reddish white, doubtless very pale yellow in life, with 

 two triangular black marks, each sending a linear process upward. 

 Pubescence dull white, long on thorax above, scanty on abdomen, 

 not forming bands. Head very broad; process of labrum broadly 

 truncate, with a depression in middle above; malar space short; 

 lower margin of clypeus arched, with projecting lateral angles, and 

 dark colored, the light areas not extending either to the margin or to 

 the sides below; clypeus distinctly, not very densely punctured, no
