short of transverse median. Second submarginal rather narrow, 

 receiving first recurrent nervure almost at its end. Third submar- 

 ginal very broad above. Femora with pale hair, tibiae and tarsi 

 with grayish brown; the creamy white shining hair of the hind 

 femora contrasts abruptly with the dark brown hair of their tibiae, 

 but the tuft on the knees is dark gray brown. Abdomen dullish, 

 not punctured, with scattered rather long pale hair, not forming 

 bands. Hair at apex sooty. Second segment in middle depressed 

 nearly one-half. 



(Comparison with the type of A. topazana shows that this is strictly 

 identical.) 



(The following is also, in my opinion, true A. topazana, although 

 there are some small differences, as the descriptions indicate.)

All have the abdomen quite distinctly banded except lincolnella. 

 a 64 . Abdomen very distinctly punctured; margins before depression red; stigma

ANDRENA ASHMEADI, new species. 



Colorado. (C. F. Baker, No. 1591.) 



Female. — Length, about 10 mm. Black, with the depressed por-
