 Described from a single specimen. 



Subfamily 1 V.— C EKAPlIRONIN.li:. 



Head transverse, when viewed from in front oval, rounded, or oblong. 

 Ocelli 3 in a triangle, rarely wanting. Mandibles oblong, bidentate at 

 tips. Antenna' elbowed, inserted at basc^ of the <'lypeus; in males 11- 

 jointed (in a single case lO-Jointed), tiliforin, dentate or subramose; in 

 females 0-, 10-, or 11-jointed, tiliform or clavate. Maxillary palpi -1- 

 or 5- jointed; lal)ial palpi 2- or 3 jointed. Pronotum short, visible from 

 above only as a transverse line; mesonotuni large, transverse, rarely 

 without grooved lines, usually with 1, 2, or 3 grooved lines; scutelluni 

 large, convex or subconvex, the axilhe .listinct; nietathorax very short, 

 rounded bel'ind, the angles slightly prominent. Front wings with a 

 large stigmated, (u- linear, marginal vein, a radial uervure, a more or 

 less distinct basal cell, and always without a postmarginal nervure; 

 hind wings simple, rather broad at base, and entirely veinless. Ai^terous 

 forms frequent. Abdomen subsessile, ovare, composed of 8 segments, 

 the second occiiiying about half its surface, striated at base. Legs 

 moderate, the posterior femora the stoutest, the tibial spurs 1, 1, 1, 

 the anterior spur large, divided into two prongs, the middle and 

 posterior spurs w'nik, short; tarsi 5-jointed, the claws small, simple. 



A somewhat extensive and widely distributed group, more closely 

 allied to the three iireceding subfamilies than to those that follow, 

 excei)t jiossibly the tribe Telenomini, in the Scelioniiue, but with quite

 with a wholly different venation, while the structure of the thorax and
