Hab. — Milwaukee, Wisconsin, May 26. (Dr. S. Graenicher.) This 

 is very similar to A. Forbesii, but that species has a transverse ridge on 

 the metathorax, and the punctures of the abdomen (especially the second 

 segment) closer. Still, they are very closely allied.

Hab. — Milwaukee, Wisconsin, June 2. (Dr. S. Graenicher.) 

 Belongs to the group of A. ri/gosa, and is allied to A. Forbesii and A. 

 grandior. 



Andrena radiatula, n. sp. 



$. — Length about 10 mm.; black; pubescence rather dense, 

 reddish-brown dorsally, paler elsewhere ; abdomen not banded ; fimbria

 hair of thorax strongly reddish ; basal area of metathorax more regularly 

 plicate and better defined ; third submarginal cell less narrowed above.
