 Gen.ch. — ^Evcs bare or pubescent, approximatc^d in tlie males, and 

 widely separated in the females ; fronto-orbital bristles extending to 

 about the apex of the second joint of the antenna? ; facial seta^ few ; 

 antenna? with the second joint somewhat elongated, and the third from 

 two to four times as long as the second ; arista bare, cheeks nude; 

 vibrisscTe placed at some distance above the upper margin of the mouth 

 (epistomc) ; abdomen conical, mostly spotted, and having both discal 

 and marginal seta^ ; wings with the fourth longitudinal vein bent at 

 an obtuse angle, and the outer cross vein placed rather nearer to the 

 angle than to the inner cross vein.

Forehead and face prominent ; frontal stripe black ; antennse grey, with the 

 third joint three or four times the length of the second ; palpi black in the male, 

 sometimes pale in the female ; thorax of the male black, with three stripes, the 

 middle one broad and sometimes trifid ; the female thorax is cinereous, and marked 

 with four narrow stripes; three outer dorso-central bristles behind the transverse 

 groove ; abdomen grey, with two distinct, large, round spots on the second segment, 

 in the male with a central dorsal black line, anal segments black and shining ; in 

 tlie female the abdomen is gi'eyish- white, with the spots very indistinct, and placed 

 more on tiie sides ; scutellura black in male, cinereous iia female ; legs black. Not 

 common ; I captured both sexes near Maidstone, in Kent, in 1891.

 This little species (from 3 to 4 mm. in size) resembles the former in its general 

 colour and markings on the thorax, but the design upon the abdomen is different, 

 there being three spots instead of two on the second segment, and also upon the 

 third ; they often coalesce, and the middle spots seem formed by a dilatation of p^rt 

 of the central stripe opposite the middle of the segments, the spot so formed being 

 sometimes on a higher level than the others ; the third joint of the antennse is 

 rather shorter in proportion than in 3I.bi!!ig)iata,B,wA. the abdominal spots are much 

 more distinct in the female. Rare ; I captured a single male near York in 1889.

 Gen. cli. — Eyes nude, widely separated in both sexes, but rather 

 nearer together in the male than female; fronto-oibit-il bristles 

 extending about as low as the root of the arista ; facial setae mostly 

 few in number ; antennse with the second joint usually short, and with 

 the third three or four times as long ; vibrissa? with the large bristles 

 placed near to the epistomc ; abdomen often wide and ovoid, as in the-
