ASHMEAD : CLASSIFICATION OF THE CHALCID FLIES 281 



3. Body of abdomen strongly compressed, sword-shaped, ending in a long ovipositor, the basal sheaths very 



broad ; all legs slender, the hind pair very long, their coxse long, cylindrical ; front wings with the 

 marginal and postmarginal veins very long, the latter extending to tip of wing, the stigmal vein very 

 small, subsessile ; antennae 11-jointed, inserted close to the mouth. .Subfamily III. Pelecinellin^. 



4. Abdomen subsessile, compressed, conically produced toward apex ; front wings with the postmarginal 



and stigmal veins very short, the knob of the latter nearly sessile, rounded ; posterior tibise comjiressed, 

 ~^ the hind margin denticulate Subfamily IV. Colotrechnin^. 



Subfamily I. CnALCEDECTiNiE. 

 1889. Polychromminse, Subfamily, Ashmead, Proc. Ent. Soc. Washington, I., p. 226. 

 1895. Chalcedectinse, Subfamily, Ashmead, Proc. Ent. Soc. Washington, III., p. 230. 



1898. Chalcodectinse, Subfamily, Dalla Torre, Cat. Hym., V., p. 186. 



1899. Chalcedectinse, Subfamily I., Ashmead, Proc. Ent. Soc. Washington, IV., p. 201. 

 The sessile abdomen and the greatly swollen and usually dentate or serrate hind 



femora, as in the Chalcididx, distinguish the family. It is not represented in 

 Europe and has reached its greatest development in South America and Australia, 

 where the species are evidently numerous. I have also seen an undescribed species 

 from Africa, where it should be well represented.
