beyond the anal cell, auxiliary vein straight, vanishing at the 

 middle of the wing, remaining veins attaining the wing margin, 

 the two basal cells equal in length, the anterior branch of the 

 third vein sinuous, rather long, the second submarginal cell 

 but slightly longer than the first along the costa. 

 Type : Empis neomexicana Melander. 



ANTHEPISCOPUS Becker.* 

 Becker has described two European species of Anthepisco- 

 pus, caclebs and ribesii, and there is one from New South 

 Wales (antipodalis Bezzi). We have a species collected at 

 Seattle, Washington, which agrees with the description and 

 figure of ribesii, but in the absence of typical specimens for 

 comparison I hesitate before deciding as to its specific identity. 



HESPEREMPIS gen. nov. 

 Male. — Eyes separated, broadly above and narrowly below 

 the antennae, the facets uniform in size. Antennae inserted 

 high, the triangular front therefore short, three-jointed, the 

 first two joints together as long as the third, the third joint 

 conical, compressed, with a short two-jointed style. The first 

 joint of the style is thick, the second very slender. Proboscis 

 very short, sharp and incurved, as in Hormopeza, etc. Palpi 

 broad, slightly longer than the proboscis, and recumbent upon 

 it, the upper surface with a few fine hairs. Ocellar triangle 

 without bristles, occiput with a few fine short hairs, face bare. 

 Thorax entirely without bristles, scu- 

 tellum with six fine marginal hairs, meta- 

 pleura bare. Abdomen slender, provided 

 with few fine marginal hairs only; a 

 transverse series of minute pits present 

 at the base of the second abdominal seg-
