? . Coarse!}' puncturetl, more finely on the abdomen than 

 ou the thorax ; median segment very coarsely rugose, longi- 

 tudinally striatetl at the base, abruptly truncate posteriorly, 

 with a blunt tubercle on each side of the truncation near the 

 middle, the siiles ot" the segment striated at the base. Abdo- 

 men broad at the base, Hrst ventral segment with a tubercle 

 beneath, second strongly angular at the base and sub- 

 tuberculate. Third cubital cell very slightly longer on the 

 radius than on the cubitus.

The flageilum is missing in the type. This is nearer to 

 punctuosus than to any ot" the other S[)eeies, but differs in the 

 shape of the third cubital cell, in the tubercles on the sides of 

 the median seounent, and in the ano;ular and subtuberculate 

 base of the second ventral segment. 1 do not think that 

 these distinctions are merely sexual.
