llab. Battle Creek, Mich. One male. 



Somewhat like P. eucera Lw. but antennae only thirteen seg- 

 mented, last segment shorter and the middle segments not so 

 deeply excised. The second posterior cell in eucera is subject 

 to considerable variation, in some of the specimens before me 

 this cell is broadly joined to the discal cell, in others it has a 

 short petiole, in a few the petiole is as long as or longer than 

 the anterior cross vein.
