ASHMEAD : CLASSIFICATION OF THE CHALCID FLIES 359 



In habits the group agrees with the Mi/mar'uhe, all the species falhng in it he- 

 ing egg-parasites. 



Two subfaniihes have been recognized : 



TABLE OF SUBFAMILIES. 



Wings without regular rows of hairs Subfamily I. OLiGOSiTiNiE. 



Wings ivith regular rows of hairs Subfamily II. Trichogrammin^. 



SUHFAMILY I. OlIGOSITIN.E. 



In the arrangement of the pubescence of the wings this group resembles most 

 closely the Eulophime, and many of the species, but for the 3-jo'mtcd Uirsi, could be 

 easily mistaken for species in that family. 



Only five genera have been described, but it is prol)able that \-ery many more 

 exist and will be discovered when more attention is given to rearing the egg-para- 

 sites of the different orders of insects.
