the abdomen. There is a foveolate groove along each side of the 

 median carina of the propodeum and a boomerang shaped carina over 

 the spiracle. The propodeum and hind coxae are more coarsely sculp- 

 tured. Occipital margin of the vertex finely scaly, more finely so 

 than the occiput. Hind tibial spur thick and of tolerable length. 

 Types compared. 



Described from one female labeled ' ' Entedon higeloviae Ashmead. 

 Type, Dalles, Oregon"; three labeled "Los Angeles, California. 

 April. Coquillett"; and three labeled "Wasatch, Utah, June 27." 



Type. — Cat. No. 19626, U.S.N.M., two females on tags, and a slide 

 bearing a hind leg and an antenna (Los Angeles). 



In this species the cheeks at the ventral ends of the eyes have a 

 broad path, which is differentiated by being scaly, not punctate (nar- 

 rower and less distinct in higeloviae) . 



EPRHOPALOTUS, new genus. 



Female. — Belongs to the Entedonini. Head large, the antennae 

 9-jointed with two large ring-joints, the club 3-jointed and with a 

 long terminal spine. Marginal vein nearly twice the length of the 

 submarginal, the stigmal long but somewhat shorter than the sub- 

 elongate postmarginal vein. Segment 2 of the abdomen a little 

 longer than 3, occupying about a fifth of the surface. Pronotum not 

 visible from above. Parapsidal furrows as in Secodella. Abdomen 

 sessile. Axillae advanced half way cephalad of the scutellum, the 

 latter large, larger than the scutum. Propodeum short at the meson, 

 there with three oarinae with sulci between them, all of the three 

 forked at base in a small way; also a larger, very delicate, shadowy 

 carina somewhat laterad of these; no true lateral carina but a 

 spiracular sulcus which is complete, running disto-laterad. Hind 

 tibial spur not especially large. 



Genotype. — Eprhopalotus purpureithorax, new species. 



EPRHOPALOTUS PURPUREITHORAX, new species. 



Female. — Length, 1.75 mm. 



Metallic purple, the propodeum, abdomen and legs blue-green. 

 Wings hyaline. Scape, tibiae and tarsi white. Venation yellow. 

 Middle tibiae concolorous for proximal half. Eaiees white. Vertex 

 scaly, also the thorax, the scutum and parapsides more coarsely 

 than the axillae and scutellum, on the scutum the lines partly raised. 

 Propodeum glabrous, scaly toward the spiracle and laterad. Abdo- 

 men scaly, glabrous at immediate base. Scape dusky above and at 

 distal half, long and slender. Pedicel a half longer than wide at 

 apex, longer than either funicle joint; 2 of the funicle a little longer 

 than 1, a little longer than wide. Terminal spine of club as long as
