Female. — About 5.5-6 mm. long; head and thorax olive green; 

 abdomen black; pubescence white. Facial quadrangle longer than 

 broad; orbits converging below; face covered with rather abundant 

 white hairs; front with close but shallow punctures, the punctures 

 more scattered on the sides of the face; supraclypeal area and upper 

 half of clypeus with a few deep punctures; lower half of cljpeus black, 

 with very few coarse punctures, fringed with yellowish hairs ; antennae 

 dark brown, the flagellum dark ferruginous beneath. Mesothorax 

 brassy green, shining, quite closely punctured; scutellum shining, the 

 disk entirely covered with delicate punctures; disk of propodeum 

 without an inclosing rim, the median portion with irregularly anasto- 

 mosing rugae, the sides of the disk plicate: mesopleurae with coarse 

 shallow punctures; truncation well defined laterally; tegulae very pale 

 testaceous, impunctate. Abdomen obovate, impunctate; apical mar- 

 gins of segments testaceous; segments 1-2 sparsely pubescent; seg- 

 ments 3-5, with more abundant white hairs. Wings clear; anterior 

 wing 4.25 mm. long; stigma and nervures pale testaceous; second 

 submarginal cell broader at the base than it is high, but contracted 

 above, receiving the first recurrent nervure very near the apex; third 

 submarginal gently contracted above, about one and one-half times as

 hairs; mesothorax opaque, microscopically tessellate with rather close,
