Antennse nearly as long as the thorax and abdomen, moderately 

 stout, tapering very slightly towards the apex, the third joint a very 

 little longer than the fourth ; the two basal joints black, the rest dull 

 brownish -red, darker on the upper surface. Head black, a little 

 narrower than the mesothorax, covered with scattered pubescence ; 

 the vertex punctured, half-shining, the front wide, projecting, pentagonal 

 area not denned ; the antennal fovea well marked, clypeus truncated, 

 labrum pale brown, palpi pale white. Thorax black, shining, covered 

 with dark down; tegulae pale, varying to black; cenchri small, clear 

 white. Legs white, with a slight yellowish tinge, coxae at base, the 

 basal fourth of the anterior, half of intermediate and nearly the whole 

 of the posterior femora, the apex of posterior tibiae and the apical joints 

 of the posterior tarsi, black ; calcaria nearly as long as the half of the 

 metatarsus ; second joint of tarsus as long as the fifth. Wings hyaline, 

 with an obscure cloud in the middle, the costa pale white, stigma fus- 

 cous, darker at the base. The first transverse cubital nervure is absent, 

 in the second cellule is a horny point ; third cellule small, nearly square ; 

 the second recurrent nervure is received about the length of the third 

 cellule in front of the second transverse cubital. Abdomen longer 

 than the head and thorax, broad, inflated in the middle; the cerci 

 small. 



The $ has the antennae short, thick, compressed, red, the two basal 

 joints black, the wings short, with the third cubital cellule small.

 basal having only the extreme tip black, but a not
