 date were taken from iicncatli l)ark of oak stmnps and loo's. 



Group E. 



All the niemhers of this group are more or less hairy and have 

 the antennte 10-jointed, the elub of male shorter than in the pre- 

 ceding groups; elypeus emarginate; inner spur of hind tibite of 

 male fixed and rather long; claws armed with a strong median tooth. 

 Three of the four known species have ham tnken in Indiana, while 

 the other probably occurs.
