ASHMEAD : CLASSIFICATION OV TITK CIIALCII) KI.IKS 343 



Flagellum short, stout, subclavate, the fmiicle li-Jointed, Joints 2 and :? not lonjfor than 

 thick, the chib stouter, ovate Mestocharis Kinster. 



23. Scutelhiin never smooth, always jMuictate, scaly-punctate or reticulate; metanotum more or less t^lia- 



greened or punctate 24 



Scutellum always smooth, inipunctate ; metanotum smooth, not sculi)lure(l. 



Flagellum subfiliform, much stouter than the small pedicel, tlie f'unicle 3-jointed, the joints 

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



24. Flagellum filiform, the funicle 3-jointed. 



Metanotum with a transverse carina at apex ; postmarginal vein short Entedon Dalman, 



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



Derostenus West wood. 



25. Antenna; short, strongly elavate, 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. Pediohind. 



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

 distinguished fi'om the other tribes by having the mesonotal furrows ineoiiii)lete or 

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

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

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



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

 attack other members of the Entedon'mac, as well as members of other groups, and 

 more particularly species in the Eidoj^hiniv ; they are the cannibals of the Enhplwhv, 

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

 genus Eulophus particularly being most frequently devoured by them.
