Type, a female collected at Child's Point, Nebraska, July 14, 

 1915, (E. M. Partridge). 



In Banks' table this runs out at zelica but differs from that 

 species in the yellow markings of the head, thorax and abdomen, 

 in its smaller size and in the different pygidial area. It is like 

 insolita in having the second abdominal tergite immaculate but 

 differs from that species in having the clypeus produced and 

 different markings of the thorax.
