Vertex, somewhat declivent, the sides sharp and meeting in front 

 almost at a right angle; the median carina wanting; lateral foveolae 

 rectangular or four sided, about twice as long as broad, very distinct. 

 Face moderately oblique. Antennae filiform, longer than head and 

 pronotum together. Pronotum with the median carina distinct, cut 

 once behind the middle by the principal sulcus; the lateral carinas 

 indistinct; strongly sinuate or curved inward; the hind margin of 

 disk broadly rounded. J lateral lobes of pronotum higher than long, 

 their front and hind margins nearly straight and vertical, the lower 

 margin with its front half inclined strongly upward. Tegmina and 

 wings well developed, equaling the abdomen in the female, usually 

 slightly surpassing its tip in the male. Iliud femora rather stout, 

 surpassing the tip of abdomen in the male, equaling it in the female. 

 Hind tibiae with the spurs on the inner side at apex, much elongated 

 and very unequal. Valves of ovipositor but little exserted, the tip 

 only being visible. Two species are known from the United States, 

 one of which has been taken in Indiana.
