356 MEMOIRS OF THE CARNEGIE MUSEUM 



The species are parasites 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 tribes have been recognized : 



TABLE OF TRIBES. 



Hind tibise with 2 apical spurs Tribe I. Eulophini. 



Hind tibise with one apical spur Tiibe II. Hemiptarsenini. 



Tribe I. Eulophini. 

 In having two apical spurs to the hind tibise this tribe agrees with the Euplec- 

 trini and the Ophelinini, in the subfamily Elachertinse, but it cannot possibly be 

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

 mesonotum, the mesonotal furrows being incomplete.

 length of the marginal vein ; pronotum semicircular, not short, narrower than the mesono- 

 tum ; abdomen ovate, depressed above, hardly as long as the thorax ; antennae 9-jointed, the 



flagellum subclavate, the funicle /owr-jointed Diaulomorpha Ashmead, g. nov.

head wide, as wide as the tborax, seen from in front a little wider than long ; antennae 10-jointed, 

 with one ring-joint, inserted a little below the middle of the face, the funicle 4-joiDted, the joints 

 long, the first much the longest, twice as long as the third, the fourth hardly longer than thick ; 

 wings with a discoidal cloud beneath the stigmal vein, the marginal vein very long, moi'e than thrice
