 % . — What appears to be the male of this species differs in having the entire 

 face, scape beneath, small triangular spots on lateral margins of mesonotum and 

 four anterior coxse and trochanters yellow : in having the rough and uneven 

 sculpturing on metathorax and abdomen more pronounced except the metatho- 

 racic cariuse. which are less prominent, and in having the transverse median
