 closest together just below antennae; frons with close distinct 

 punctures; vertex with widely scattered punctures; ocelli in an 

 obtuse triangle; postocellar line subequal with ocellocular; an- 

 tennae short, stout, distinctly thickening apically, third joint

 riorly, the lateral angles rounded ; scutum shining, very sparsely 

 punctured; notauli indicated on anterior half of scutum; suture 

 in front of scutellum feebly foveolate ; scutellum shining with a

 nearly smooth; mesepisternum polished, the suture strongly 

 foveolate ; petiole strongly curved, cylindrical, subequal in length

 gaster polished; first recurrent received near base of second 

 cubital cell ; second recurrent sinuate, joining third cubital cell a 

 distance equal to about half the length of second intercubitus 

 from base of cell ; second cubital cell about three times as long 

 on cubitus as on radius. Black; scape, basal joints of antennae, 

 and flagellum beneath ruf opiceous ; tubercules and tegulae testa-

 an incomplete transverse ridge, which medianly joins frontal 

 carina; eyes closest together opposite antennas, the area be- 

 tween eyes narrow; frons and vertex polished; lateral ocelli 

 in pits ; ocelli in an obtuse triangle ; postocellar line shorter than 

 ocellocular line; antennas extending a little beyond hind margin 

 of tegulae, thickening apically, third joint longer than fourth; 

 anterior margin of pronotum sharp, the lateral angles sharp;

 for about three-fourths the length of scutum ; suture in front of 

 scutellum not foveolate ; scutellum shining, with sparse setigerous
