Black, polished, the mandibles and all the legs ferruginous, the tarsi, at least the 

 hind and middle ones, more or less infuscate above, the pedicel of the antennae 

 obscurely red or pitchy. 



Antennae moderately long, rather longer than the head and thorax together, 

 13-jointed, the pedicel hardly longer than wide, the first funiclar joint elongate, more 

 than twice as long as wide, distinctly, though not greatly, longer than the second, and 

 about equal to the third ; the first and second distinctly more slender than the latter, 

 the latter more so than the fourth, this and all the following being subequal and 

 moniliform, each longer than wide, and all fluted. Mesonotum very smooth and 

 shining, with sparse pale hairs ; scutellar cup narrowly ovate, pointed anteriorly, twice 

 as long as its greatest width, with a large fovea posteriorly, and with some distinct 

 piligerous punctures on each side in front of the fovea ; sides of scutellum beneath the 

 disc distinctly rugose and posteriorly pilose. Meso- and metapleura smooth. Wings 

 hyaline, ciliated, neuration dark and strong, the marginal cell open above for about half 

 its length, the cubitus much fainter than the rest of the neuration. Propodeum carinate 

 on each side of the middle, the surface dull and thinly pubescent. Abdomen about 

 equal in length to the head and thorax together, with a rather sparse and inconspicuous 

 hairy girdle at the base, the hypopygium strongly exserted. Length 2 mm. $.
