630 FAUNA HAWAIIENSIS 



dull, hairy and pubescent, the rest of the abdomen smooth and polished. Length about 

 I '5 mm. ^. 



Possibly this species should be referred to Ashmead's genus Ceratopria. 



Hab. Oahu, Honolulu ; no doubt introduced. 



CHALCIDOIDEA. 



The endemic Chalcids are chiefly, if not solely, represented by the Families 

 Miscogasteridae, Encyrtidae, Eulophidae, and possibly a few species of Pteromalidae 

 of the subf. Spalangiinae. In these families only a few genera are represented by 

 native species, but there are a good many unquestionably introduced ones, represented 

 each by only one or a few species. New forms are constantly appearing in Honolulu, 

 having been accidentally introduced with plants from other countries, or in some cases 

 purposely for economic reasons. 



Two or three species of Chalcididae have been recently introduced and one has 

 now become a very common insect and will soon, no doubt, be ubiquitous. 



Fam. EURYTOMIDAE. 



EURYTOMA 111. 



(i) Euryionia sp. ? 



Hab. Oahu, Hawaii and probably all the islands. A recent introduction now 

 common, parasitic on various Braconids. 



IsosoMA Walker. 



Isosoma spp. ? 



Two species of this genus occur in foreign grasses and are now widely distributed 

 in the islands. 



Fam. ENCYRTIDAE. 

 Subfam. EUPELMINAE. 

 In addition to the species described below I know two or three other species of 

 Eupelmines, all introduced and not yet determined. 



EuPELMUS Dalman. 



The species of this genus are numerous in the islands and I suspect that Ashmead 

 included many species under the two names E. vtUgaris Ashm. and E. Jlavipes Cam. 

 To these two species he assigned the whole of my numerous specimens, excepting nine 

 individuals, of which five were named E. konae, the other four each representing a
