356 MEMOIRS OF THE CARNEGIE MUSEUM 



The species are jjarasites of the Micro-lepidoptera, and particularly the leaf- 

 miners, although other groups are also attacked by them. Some are also said to be 

 hyperparasites of other Chalcidoids. 



Most of the species are very small, of brilliant metallic colors, and the antennae 

 in many males are ramose or branched. 



Two triljes have been recognized : 



TABLE OF TRIBES. 



Hind tibiffi with 2 apical spurs Tribe I. Eulophiiii. 



Hind tibiw with one apical spur Tribe II. Hemiptarseuini. 



Tribe I. EuJophiiu. 

 In having two apical spurs to the hind tibite this tril^e agrees with the Eupkc- 

 trini and the OpheUnini, in the subfamily Elachertinx, but it cannot possibly be 

 confused with these tribes, if attention is given to the difference pointed out in the 

 mesonotum, the mesonotal furrows iDcing incomplete.
