truncate at the apex. Hind tibise spinose ; hind femora without 

 a rounded lobe at the apex beneath. Second abscissa of the 

 radius equal to the first, the two combined shorter than the third ; 

 first transverse cubital nervure oblique, sharply bent close to the 

 cubitus ; first recurrent nervure received close to the middle of 

 the second cubital cell, second just before one-third from the 

 apex of the third cubital cell. Cubitus of the hind wing 

 separated from the transverse median nervure by a distance equal 

 to one-third of the length of that nervure. 



Black ; the inner margin of the eyes narrowly whitish ; calcaria 

 whitish ; wings hyaline, tinged with fuscous, nervures fuscous.

(S • A minute tubercle in the middle of the clypeus ; pronotum 

 not much narrowed anteriorly, not more than half as long as the 

 scutellum ; first dorsal segment a little narrower at the apex than 

 long, a little longer than the second segment. Hind tibiae very 

 distinctly spinose ; hind femora with a very distinct rounded lobe 

 at the apex beneath. Second abscissa of the radius longer than 

 the first, the two combined about equal to the third ; first 

 recurrent nervure received at the middle of the second cubital 

 cell, second beyond one-third from the base of the third cubital 

 cell. Cubitus of the hind wing originating just before the 

 transverse median nervure. 



Black ; mandibles at the base, clypeus, posterior margin of 

 pronotum, tegulse, a spot on the mesonotum, postscutellum, a 

 spot on each side at the apex of the median segment, a small 

 lateral spot on each side of dorsal segments 1-5, a large spot on 

 each side of the seventh segment, the base of the tibiee and 

 the base of the tarsi whitish yellow ; the apex of the seventh 

 dorsal segment testaceous. Wings hyaline, tinged with fuscous ; 

 nervures fuscous.

S . Clypeus truncate at the apex ; pronotum much shorter 

 than the scutelkim, very slightly narrowed anteriorly. First 

 dorsal segment no longer than the apical breadth ; seventh dorsal 

 segment broadly rounded at the apex. Hind tibiae very feebly 

 serrate; hind femora without a lobe at the apex beneath.
