black and white flat scales and brown border-bristles; metanotum black; prothoracic lobes with flat white scales; pleure deep brown with patches of flat white scales.

Abdomen deep brownish black, the fifth to seventh segments with large, silvery white, basal patches, and a small one on the eighth segment; border-bristles dark; each segment with basal, white, lateral patches, large on basal segments, becoming linear on the apical ones, venter dark with broad, basal, white bands.

Legs dark with basal banding; the fore and mid metatarsi and first tarsal segments with basal creamy bands; the fore femora with traces of white scales. near the apex forming a spot, very prominent on mid femora, apex white especially in the mid legs, paler scales below at the base; hind femora white below at the base and apex; metatarsi and first two tarsi with basal white bands, nearly all the third tarsals white, apical one black; ungues of fore and mid legs equal and uniserrate, hind equal and simple.

Wings with the first submarginal cell longer and narrower than the second posterior cell, its base nearer the base of the wing, its stem about one-third the length of the cell, stem of the second posterior rather more than half the length of the cell; posterior cross-vein about three times its own length distant from the mid.

Halteres with base of stems ferruginous, apex fuscous and also knob. Length: 4 mm.

Time of capture: 7, viii., '07, and 9, ix., '07.

Habitat: Obuasi and Kumasi.

Observations: Two 9's both taken in bush, one at 5 p.m. at Kumasi. Dr. Graham says specimens taken in bush paths outside Obuasi and outside Kumasi in August and October, from 2 to 5 p.m. Described from a perfect ?. The marked thoracic ornamentation and the leg banding combined will at once separate it from all other African Stegomyia.
