Female : Head a little wider than long, rather thick, the cheeks con- 

 vergent towards the truncate mouth, the face reflexed, the frons rather 

 narrow and not prominent ; eyes rather small, very broadly oval ; f ronto- 

 vertex two and a half times as long as wide at the middle, being widened 

 both anteriorly and posteriorly ; ocelli arranged in an acute-angled tri- 

 angle, the anterior one at the center of the frontovertex, the posterior 

 pair almost touching the eye-margins and remote from the occipital 

 margin ; face and cheeks as long as the eyes, the scrobes in the form of 

 a triangular impression divided below by a median, moderately elevated 

 ridge between the antennae. Antennae inserted close to the clypeal 

 margin and formed much as in Apliycus; the scape compressed, but not 

 expanded beneath; the pedicel about as long as the first three funicle 

 joints combined; funicle joints all a little wider than long, increasing 

 distinctly in width and more slightly in length distad ; the club large, 

 oval, wider than the funicle and as long as the five preceding joints com- 

 bined. Mandibles with an acute ventral tooth, and a broad dorsal one.

 short, narrowly transverse and scarcely arcuate ; mesoscutum nearly 

 twice as wide as long, the posterior margin slightly sinuate on either 

 side of the middle which is slightly produced caudad ; axillae much wider 

 than long and nearly meeting at the middle; scutellum very large, some- 

 what longer than wide, the sides slightly rounded in outline and strongly 

 declivous, the apex rounded; propodcum very sliort at tlie middle and 

 not greatly enlarged laterally. Abdomen very small, scarcely one-half as 

 long as the thorax, depressed, triangular with the basal corners rounded 

 and the apex rather acute ; the vibrissal plates situated a little before 

 tlie middle just within the lateral margin on the ventral side; fifth 

 ventrite reaching half way between the middle and apex ; ovipositor 

 internally reaching nearly to the base of the abdomen, apically free 

 beyond the fifth ventrite and slightly protruded. 



Legs stout, moderately long, the middle tibiae much enlarged at apex 

 and the middle tarsi strongly incrassate. Discal ciliation of wings dense 

 and' uniform, the speculum widened below, marginal fringe short and 

 dense ; submarginal vein broken where it joins the thickened apical part, 

 the basal portion with six long bristles wliicli gradually shorten on
