times the antennal length. Thorax cf nearly bare, narrowly tomentose 

 before the scutelkim and around the root of the wing and conspicuously 

 so below the humeri ; pleura shining ; one strong humeral, four supraalar, 

 one intraalar almost posthumeral in position, two prescutellar, four 

 scutellar, the lateral ones short; in the 9 the notal hairs are long, fine, 

 abundant and whitish, the lateral bristles are shorter and the sub- 

 humeral region is provided with white hairs instead of tomentum. 

 Abdomen shining, nearly bare, in the cf the hairs are blackish and 

 stronger, along the sides of the middle segment slightly flattened, 

 hypopygium short, rather small, its appendages open above. Legs 

 sometimes more or less reddish near the end of the hind tibiae, the 

 hind metatarsi not setulose, apical spines of the anterior tibiae long. 

 Halteres white, calypteres with about eight dusky cilia. Wings yellowish 

 hyaline, veins pale brown, first posterior cell rather broad, its veins 

 parallel outwardly, the second, third and fourth sections of the costa 

 proportioned 1.3 : 1.3 : 1, anterior cross-vein at three-fourths the length 

 of the second basal cell, outer two sections of the fourth vein propor- 

 tioned 1 : 7, of the fifth vein equal, marginal cilia uniformly short. 



Numerous specimens from Washington, Idaho, Massa- 

 chusetts and Maine. One specimen from Olga, Washington, 

 has three extensor bristles on the hind tibiae. 



Eudrapetis discalis, sp. nov. 

 cf . Length 1.4 mm. Shining black, closely pubescent, legs yellow, 

 posterior cross-vein at the middle of the wing. Occiput with short, 

 brownish hairs and bristles; front V-shaped, at the bottom one-half as 

 wide as the second antennal joint, face and cheeks linear; palpi blackish 

 with a few brown hairs, proboscis short, black; antennje ascending, the 

 second joint with a seta, the third joint short-ovate, the subterminal 

 arista slender, bare, over three times the antennal length. Hairs of the 

 thorax short, dense, pale, no humeral, three supraalar, four scutellar 

 bristles. Sides of the abdomen subopaque, with white pubescence, disk 

 shining, hypopygium elongate, outwardly with white hairs. Legs 

 slender, the hind femora with short preapical bristles, no tibial bristles 

 or spur. Halteres blackish. Wings hyaline, veins narrow, brownish, 

 third and fourth veins subparallel, the third lightly sinuose, so that the 

 first posterior cell is widest before its apex, second, third and fourth 

 sections of the costa proportioned 1.4 : 1.8 : 1, anterior cross-vein at 

 two-fifths the length of the second basal cell, the outer two sections of 

 the fourth vein proportioned 1 : 1.8, of the fifth vein, 2:1, marginal 

 cilia uniformly very short. 



Two specimens: Wawawai, Washington, and Palo Alto, 

 California. 



Eudrapetis diversipes, sp. nov. 



c^. Length 1.9 mm. Black, shining, legs yellowish, the hind femora 

 and metatarsi blackish, hairs of the thorax rather sparse, fine and pale, 

 hypopygium very large. Vertex, front and face grayish black, vertical
