5 . Radial cell rounded at the apex ; second abscissa of the 

 radius twice as long as the first, but distinctly shorter than the 

 third ; first recurrent nervure received close to the middle of 

 the second cubital cell, second at about one-fifth from the base 

 of the third cubital cell. Tarsal ungues bifid ; lobe beneath the 

 apical third of the hind femora scarcely rounded, basal joint of 

 hind tarsi with a thinly-set row of very short spines beneath. 

 Finely and rather closely punctured, median segment finely 

 rugulose ; abdomen shining, very finely and sparsely punctured. 

 Basal joint of fore tarsi not strongly produced at the outer apical 

 angle. 



Black, with long black pubescence ; calcaria black ; flagellum 

 bright orange. Wings fusco- violaceous. 



cJ . Third abscissa of the radius twice as long as the second in 

 some specimens, shorter than the second in others ; first recurrent 

 nervure received by the second cubital cell at a distance from the 

 base slightly less than the length of the first transverse cubital 

 nervure, second either interstitial with the second transverse 

 cubital nervure or received a little before the apex of the second 

 cubital cell. Apical joint of antennae no longer than the 

 penultimate. Basal abdominal segment nearly twice as broad 

 at the apex as long. Very finely and closely punctured, minutely 

 on the abdomen. 



Colours as in the female.
