 the apex of the third rufous ; the four posterior tarsi yellowish ; 

 the basal joints black, except at the apex. Wings fulvous, 

 with a violaceous tinge ; the stigma rufo-testaceous ; the 

 second cubital cellule at the top is as long as the space 

 bounded by the first transverse cubital and the first recurrent 

 nervures ; the second and third transverse cubital nervures are 

 parallel and roundly curved outwardly from shortly above the 

 middle. Abdomen dark rufous. The base of the petiole

The male has the face, clypeus, and mandibles paler, of a

 impunctate ; the apex is bluntly rounded, the lateral angles 

 above are more rounded ; the antennal tubercle is narrowly 

 furrowed in the middle above ; the mesopleuras rufous, with 

 three irregular marks above and in the middle behind, the 

 latter being the larger and narrowed in the middle ; the four 

 anterior coxas are only black at the apices, the posterior are 

 irregularly marked with yellow behind ; the black on the

 of the last joint of the antennas from the base of the mandibles. 

 Clypeus roundly convex, strongly but not very closely punc- 

 tured. The base of the mandibles with scattered punctures, 

 their three apical teeth are of equal size. Thorax black, 

 except the prothorax and the sides of the scutellum, which are
