Dolichopodidae. 363 



tarsi black except the base. The legs have short, black hairs, coxæ 

 pale-haired ; front coxæ with a single or a pair of black, bristly hairs 

 at the apex, posterior coxæ each with a black bristle, small or very 

 small on the middle coxæ; front femora slightly thickened at the base, 

 but, for the rest, together with tibiæ simple and without bristles; 

 middle femora slightly dilated below, and slightly and evenly excised 

 before the apex ; they have fine hairs below at the base and 

 two rows of bristles on the apical half, the postero-ventral row 

 strongest and its first bristle long; the middle tibiæ are thin at the 

 base, then suddenly somewhat thicker, and again a little thinner at 

 the apex; they have an antero-ventral row of short bristles, very 

 short on the thin basal part, and a postero-ventral row of long, distant 

 bristles with the apex truncate, not pointed (as is also the case with 

 the bristles on the femora); on the elevated part before the apical 

 thinning there are short, strong and dense hairs and some bristles on 

 the dorsal and anterior side, and finally a dorsal bristle about in the 

 middle; the middle metatarsus is short and thick, three or four times 

 shorter than the long second joint and ending with some spines and 

 hairs; hind femora with a ventral row of alternating long and short 

 bristles, and with a preapical bristle; hind tibiæ with a few dorsal 

 brisles, and about two ventral; hind metatarsus somewhat shorter 

 than the second joint. Wings brown tinged; veins black, the con- 

 vexity on the last part of the discai vein with a generally very slight 

 darkening; the posterior cross-vein most often a little behind the 

 middle, the part of the discai vein from the small to the posterior 

 cross-vein about as long as or slightly shorter than the second part. 

 Squamulæ yellow or reddish yellow, with a blackish fringe. Halteres 

 yellow or dark yellow. 



Female. Epistoma slightly broader than in the male, white above, 

 brownish yellow below ; frons a little greyish pruinose, especially below.

Antennæ with the third joint shorter than in the male, but relatively 

 longer than in the female of scamhus. Legs simple, front tibiæ with 

 a dorsal and a posterior bristle; middle tibiæ with three antero-dorsal 

 and one postero-dorsal bristle, and with two ventral bristles. 

 Length 2,3 — 2,7 mm.
