June, 1903.] ASHMEAD : CLASSIFICATION OF THE PkOCTOTRVPOIDF.A. 87 



Abdomen broadly oval or long oval, the third segment much the longest; post- 

 marginal vein never developed. 

 Marginal vein very short, punctiform or thickened, not or hardly as long as the 

 stigmal vein ; stigmal vein short, thickened at base and ending in a rounded 

 stigma; antenna in 9 7-jointed, the club being unjointed, in $ l2-jointed, 

 filiform-moniliform ; lateral ocelli usually close to the eye margin ; females 



usually apterous Subfamily II. B.EIN^t. 



Marginal vein very long, usually 5 or 6 times as long as the exceedingly short 

 stigmal vein ; stigmal vein not thickened at base ; antenn;^ in 9 12-jointed, 

 clavate, the club 5- or 6-jointed, in $ 12-jointed but filiform, the funicle 

 joints long ; lateral ocelli not close to the eye margin ; females rarely 



apterous Subfamily III. TELEASIN.E. 



2- Marginal vein seldom twice as long as the stigma vein ; stigmal vein not especially 

 short, oblique, rarely entirely absent ; if the post-marginal vein is wanting, the 

 submarginal vein ends in a stigma; antennce in 9 i2-jointed, clavate, in J 

 12-jointed, usually filiform, in a single genus lo-jointed. 



Subfamily IV. SCELIONIN/E. 



Subfamily I. TELENOMIN^. 



This is a most interesting group first recognized by C. G. Thom- 

 son, the eminent Swedish entomologist. Many species have been 

 described, the majority living parasitically in the eggs of Lepidoptera 

 and Hemiptera. 



Hcmisiiis \\'est\vood, may be an older name for Telcnoiius Haliday. 



Aleria Marshall, described in 1874, also belongs here, I think, but 

 it is too insulificiently characterized to be incorporated in my table.
