ASHMEAD : CLASSIFICATION OF THE CHALCID PLIES 359 



In habits the group agrees with the Mymaridse, all the species falling in it be- 

 ing egg-parasites. 



Two subfamilies have been recognized : 



TABLE OF SUBFAMILIES. 



Wings without regular rows of hairs Subfamily I. Oligositin^. 



Wings with regular rows of hairs Subfamily II. Teichogeammin^. 



Subfamily I. OLioosiTiNiE. 



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

 closely the Eulophinse, and many of the species, but for the 3-jointed tarsi, could be 

 easily mistaken for species in that family. 



Only five genera have been described, but it is probable that very many more 

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

 sites of the different orders of insects.
