 pleurae finely longitudinally striated. Scutellum carinate along the 

 sides. Metanotum with one transverse keel near the base ; the base 

 behind it finely rugose ; the rest of the surface finely rugose and bear- 

 ing arcuate keels. Metapleurae finely rugose. Petiole shining, glab- 

 rous, slightly hollowed in the center above at the base ; postpetiole 

 clearly separated from and distinctly thicker than the petiole, densely 

 covered with a white pubescence ; the petiole itself is narrowed at the 

 apex; together they are nearly as long as the second segment, which 

 is dilated at the apex. The transverse radial nervure is curved up- 

 wards in the middle on the basal division, the apical portion having a 

 gradual curve from the base to the apex, the extreme apex curved up- 

 wards ; the angle formed at the apex of the first cubital cellule shorter 

 on the upper than on the lower side."
