Extract

In my neighbourhood I find the typical Andrena Cressonii, Rob., and the form described below as A. dubia, the latter more rare. To compare this with the form described as A. Bridwellii,Ckill., I have obtained from Mr. Bridwell for examination thiry-three specimens taken by ghim at Baldwin, Kansas, and labelled A. Cressonii, A. Kansensis, and A. Bridwellii.

A. Kattsensis is the same as A.Cressonii, the colour of the pubescence being characteristic of unfaded specimetrs. Local specimens sometimes have the hind tibiæ and tarsi ferruginons in both sexes.
