 scape subcompressed, wider towards the apex or clavate in outline 

 as seen from the side, and rather short or barely reaching to the plane 

 of the frontovertex; pedicel about one-half longer than thick, much 

 thicker at the apex than the following joint and a hitle longer than 

 the first three funicle joints combined; flagellum short, distinctly Init 

 not greatly clavate: first four funicle joints all sliort, transverse and 

 about equal in length, the last two funicle joints twice as long as the 

 preceding joints, the fifth about as long as its apical width, the sixth 

 a little wider than long; club narrowly ovate, rounded at apex, consid- 

 erably wider and a little longer than the funicle, its basal joint some- 

 what the longest. Mandibles with a sharp spine on the ventral margin, 

 the apex broad, with two strong acute, ventral teeth and a broad 

 inner truncate margin. Maxillary palpi .slender, moderately long, 

 the basal joint a little longer than the second or third wliich are about 

 equal, the fourtli joint as long as the first two combined; labial palpi 

 short and stout, the apical joint sliglitly longer than the basal and 

 rounded at apex. 



Thorax depressed, its depth hardly greater tlian one half the width, 

 and about one half longer again than wide ; pronotum deeply arcuate and 

 narrow ; mesoscutum very flat, about one half wider again than long, 

 its posterior margin slightly angulate at the middle ; axillae short, 

 considerably over twice as wide as long, and meetin;4 at their tips; 

 -scutellum a little wider than long, about rectangular at apex, the disk- 

 nearly flat, not greatly elevated and abruptly sloping downward along 

 tlie lateral margins ; propodeum very short medially but triangularly 

 enlarging towards the sides, the metapleura small and narrow Imt 

 reaching to the hind coxae. Dorsum of alidomen moderately sunken in. 

 the venter depressed with the fifth ventrite reaching aiiout to tlie mid- 

 dle and leaving the ovipositor free : protruded part of tlie o\ipositor 

 sheaths terete; vibrissal plates situated on the lateral margins of the 

 dorsum half way between the base and the middle, the vibrissae falling 

 considerably short of the apex. 



Legs normal, the tarsi slender and not tliickened at base, tlie first 

 joint of the middle pair as long as the four fallowing joints combined 

 and a little longer than the slender tit)ial spur. W'ings narrow, 

 reaching considerably lieynnd tlie apex of the alulomen ; venation reach-

 slightly l)roken at a point one third of its length from the distal 

 end, marginal vein stout and about four times longer than thick, stigmal 

 vein about one half as long, narrow at basQ and triangularly enlarged 

 at apex, the postmarginal sliort and spurlike ; speculum narrow and of 

 equal width throughout, falling somewhat short of the .stigmal vein but 

 extending to the bare area along the posterior margin of the wing, 

 and interrupted near its lower end by two stout bristles: marginal cilia 

 rather long, the discal cilia extremely various and helping to form the 

 fuscous rays and band, those on the l)ase of the disk before the specu-
