The male is coloured like the female, including the antennae ; 

 the penultimate ventral segment is laterally, broadly, roundly 

 incised. It wants the round spot on the pleurae behind the 

 tubercles. The eyes in both sexes strongly converge below ; the 

 antennae clavate, short. In the female the eyes near the face are 

 separated by distinctly more than the length of the antennal 

 scape : in the male by very little more than its length. The wings 

 in both sexes are clear hyaline ; the costa is testaceous.
