$. Long. Corp. 6 mm. ; al. 5 mm. Dark metallic green. Vertex metallic green, 

 front and face covered with white tomentum, proboscis and palpi black. Antennae entirely 

 black, cilia of posterior orbit black. Thorax and scutellum dark metallic green, without 

 stripes, the latter with two long bristles and two minute fine hairs, one on each side near 

 the base, halteres pale yellow. Abdomen dark metallic green, unicolorous, first segment 

 fringed on its posterior margin with long black hairs, succeeding segments also fringed, 

 but with shorter hairs, hypopygium blackish, with the exterior appendages yellowish, 

 rather short, sub-claviform, and tipped with long black hairs. Legs entirely black and 

 shining, all the femora with a slight greenish tinge and a few small bristles near the tip 

 beneath, fore tibiae with two, and intermediate with three bristles on their outer surfaces, 

 hind tibiae with four or five bristles on the outer surface and three small ones on the 

 inner surface. Wings tinged with brownish, which is deeper in their apical half, without 

 spots, veins blackish, ist longitudinal vein terminating at about one-fourth of the length 

 of the costa, 3rd and 4th veins slightly converging in their apical third, posterior cross- 

 vein slightly curved, about half its length from the posterior margin of the wing. 



%. Long. Corp. 6 — 7 mm. ; al. 6\ — 8 mm. Very similar to, but larger than the 

 male, with the wings much darker tinged. 



Hab. Hawaii, one male, Olaa, December 1896. — Molokai Mts., 4 — 500 ft., one 

 female, August 1893. — Kauai, one female, Waimea Mts., 4000 ft., 1894. 



? Gen. nov. ct sp. A male Dolichopodid from Waimea Mts., Kauai, obtained in 1894 

 at a height of 4000 ft., may form the type of a new genus. As the specimen is in bad 

 condition, however, I prefer to leave it undescribed. It appears to be related to Hvdro- 

 phorns and Medctcrus, but the thorax has a concave depression behind, the scutellum 

 has six bristles, the abdomen six segments, the last very short, the hypopygium not 

 imbedded and the middle tibiae with long spines.
