 ture proceeds a black hair. Head between globose and triangular, very hairy with a naked spot 

 behind the eyes ; cheek terminating in a tooth or point as in the other species of the genus ; vertex 

 blue-green : antenna; black, shorter than the thorax ; palpi piceous : trunk subglobose, with the cen- 

 tral part of the thorax, and the part between the four anterior legs tinted with green : legs rufous 

 with the coxae and trochanters black : wings hyaline with piceous nervures : abdomen naked, ter- 

 minated by a subtriangular acuminated mucro or horn ; ovipositor piceous.
