Genus PSEUDOPANDRGUS Cockerell. 

 i. Pseudopanurgus fuscipennis (Crawford). 



The only records of this bee are the two cotypes collected 

 by Mr. J. C. Crawford, at West Point, Nebraska, September 

 18 and 20, 1903, on Bidcns chrysanthemoidcs. It is suggested 

 that this species is likely to prove the same as P. aethiops Cres- 

 son, but we have not been able to make a direct comparison, 

 so leave it as distinct. Protaiidrenopsis Crawford, however, 

 is the same as Pseudopanurgus Ckll. 



Genus PROTANDRENA Cockerell. 

 i. Protandrena asclepiadis Cockerell. 



Entire State except in Transition zone of Sioux County; 

 West Point, Weeping Water, Cams and Dundy County, Ne- 

 braska, flying during July on Pctalostcnnni violaccus, Solatium 

 rostratum, Mclilotus alba, Symphoricarpos occidcutalis and 

 Medicago sativa. P. bancrafti Dunning, described from Colo- 

 rado, is the female of P. asclepiadis Ckll., and the species should 

 be known by the older name, as above.
