 rounded posteriorly, the tibise and tarsi of the legs less spinose, and 

 the abdomen more cylindrical in form. Black ; the wings light

" Black, the wings fusco-violaceous. Eyes almost parallel. 

 OcelU separated from the eyes by a distinctly greater distance than 

 they are from each other. Clypeus with the sides rounded, the 

 middle slightly waved and margined. Head moderately well- 

 developed behind the eyes ; the occiput a little concave. Pro- 

 notum hardly so long as the head ; the sides rounded. Median 

 segments (segment?) a little longer than the prothorax, having a 

 gradually rounded slope to the apex ; the middle with a wide 

 shallow furrow ; alutaceous, covered with a fulvons down. Abdo- 

 men shining; the petiole becoming gradually wider towards the 

 apex, so that it is then more than twice the width of the base. 

 Apical segment rugose, thickly covered with stiff hairs. The 

 second cubital cellule at the top more than twice the length of the 

 third, at the bottom equal in length to it; the third at the top 

 about one-third the length of the bottom ; third transverse 

 cubital nervure with a gradual curve to the top ; the first recurrent 

 nervure is received near the apex, the second a little beyond the 

 middle. Legs pruinose; the spines sparse; the long joint (sic) of 

 the hind tibiae short, not reaching the middle of the metatarsus.
