ASHMEAD : CLASSirrCATION OF THE CHALCIU FLTES 343 



Flagellum short, stout, subclavate, the fuuicle 3-jointed, joints 2 and 3 not longer than 

 thick, the chib stouter, ovate Mestocharis Forster. 



23. Scutellutn never smooth, always punctate, scaly-punctate or reticulate ; metanotum more or less sha- 



greened or punctate 24 



Scutellum always smooth, impunctate ; metanotum smooth, not sculptured. 



Flagellum subflliform, much stouter than the small pedicel, the funicle 3-jointed, the joints 

 loosely joined or briefly pedicellate, postmarginal vein short Asecodes Forster. 



24. Flagellum filiform, the funicle 3-jointed. 



Metanotum with a transverse carina at apex ; postmarginal vein short. Entedoii Dalman. 



Metanotum with a tranverse carina a little before the apex ; postmarginal vein long. 



Derostenus Westwood. 



25. Antennse short, strongly clavate, pubescent. 



Pedicel not large, narrower than the first joint of the funicle Rhopalotus Forster. 



Pedicel very large, stouter than the first joint of the funicle Chrysoatomus Ashmead. 



Tribe IV. Pediobiini. 



In this tribe are found some of the smallest members of the subfamily. It is 

 distinguished from the other tribes by having the mesonotal furrows incomplete or 

 wholly wanting, at the most indicated by a slight depression posteriorly, but not by 

 grooved lines. In the other tribes the mesonotal or parapsidal furrows are usually 

 complete and always sharply defined, the raesonotum being distinctly trilobed. 



All of the species falling in this group, or tribe, are, I think, hyperparasites and 

 attack other members of the Entedoninse, as well as members of other groups, and 

 more particularly species in the Eulophinse. ; they are the cannibals of the Eulophidse, 

 since they attack and devour almost any member of the family, the species of the 

 genus Eulophus particularly being most frequently devoured by them.
