 next the eye, one-half wider than long, rather acutely pointed. Pronotum 

 about one-half longer than vertex, scarcely wider than head, less than

External genitalia : Female, last ventral segment half longer than pre- 

 ceding, narrowed posteriorly, posterior margin with a large median lobe; 

 pygofers narrow, slightly exceeded by the black-tipped ovipositor, with 

 a few apical spines. Male, valve nearly as broad and fully as long as 

 last ventral segment, posterior margin very slightly emarginate; plates 

 over twice as long as the valve, lateral margins slightly concave medially, 

 with a few bristles in the concavity, apices subacute, exceeding the short
