1916] Girault — New Encyrtidae from North America . 43 



Types: Catalogue No. 19211, U. S. N. M., four females on two 

 tags plus a slide bearing appendages. 



Nebaocharis gen. nov. (Ectromini) 



Female: In Ashmead's table runs to Anvsia Foerster but 

 differs in having the antenna! club solid, the ovipositor exserted 

 for three fourths the length of the abdomen, wings are present in 

 the shape of large scales and the head is not so long, not so nar- 

 rowed beneath the eyes, the cheeks short. Also the pronotum is 

 less conical, shorter than the scutum or scutellum. Abdomen 

 slender, depressed, its segments very indistinct. Head subquad- 

 rate but somewhat narrower toward the mouth (cephalic aspect), 

 the face lenticular but the short, rather shallow scrobes forming a 

 short semi-circle. Axillae apparently rather widely separated. 

 Hind tibial spur single. Type: N. hemipterus, sp. nov. 



Nebaocharis hemipterus sp. nov. 



Length, 1.00 mm. Dark brown, the abdomen, antennae, ex- 

 truded valves of the ovipositor and the hind legs, purplish black; 

 scutellum nearly black. Legs, including the caudal tibia just 

 below knee and the caudal tarsus, yellow. Body glabrous or 

 nearly but the head coarsely scaly. Pedicel not flattened, slightly 

 longer than wide, slightly longer than funicle 3 which is slightly 

 the longest, 6 subequal to 2, 1 cupshaped and smallest, all wider 

 than long and compressed ; club conical, no wider than the funicle 

 and about half its length. Scape greatly dilated. Flagellum 

 clothed with very short hairs. 



Described from one female in the U. S. N. M. collections, labelled 

 "Colorado, 2019. C. F. Baker." Type: Catalogue No. 19312, 

 v.. S. N. M., the specimen on a tag, the head and a hind leg on a 

 slide. 



Xanthoencyrtus Ashmead { = Scelioencyrtus Girault.). 



The original description of Xanthoencyrtus disagrees with my 

 own of Scelioencyrtus, which is correct. The club is 2-jointed, 

 and the genus must at present be regarded as an Ectromine. Xan- 

 thoencyrtus nigroclavatus Ashmead appears to be common in the 

 United States; through the Bureau of Entomology I have seen a 

 series of both sexes labelled "Webster No. 11811, Elkpoint, S. D.
