more or less broadly blackish, the colour confined to the middle of 

 the disc on the basal ones, but extending to nearly or quite the 

 full width in the others. Venter and genitalia in both sexes 

 black, with some soft hairs. Lccjsm <S all black ; in 5 yellowish; 

 hind pair and anterior tarsi blackish ; all legs devoid of pubescence, 

 except for a few short hairs below tip of posterior femora. Winr/s 

 brownish in cj' , very pale grey in $ , almost clear : subcostal cell 

 yellowish for some distance from tip ; halteres yellowish, knobs 

 blackish ; tlioracic squamse very large, yello\vish, with a fringe of 

 pale hairs.

Subfamily TOXOPHOKINJ^.. 



Head moderately transverse, rounded behind eyes, as wide as 

 or a little wider than thorax, generally considerably depressed. 

 Eyes in S contiguous or subcontiguous, the front facets some- 

 times enlarged, no indentation in middle of hind margin ; in $ 

 widely separated. Face usually produced over the long narrow 

 moutli-opening; proboscis generally long, slender, or short and 

 thick ill some (non-Oriental) genera (Ci/llenia); palpi long and thin 

 in Toxophora, short in some genera. Anteniite closely approximate 

 at base, porrect, as long as or longer than iiead. Vertex with a pair 

 of strong bristles in To.vophora. ThorcLc very hum]ied,with scaly 

 pubescence in some genera and strong side bristles in Toxophora ; 

 scutellum rather large and with strong marginal bristles in 

 Toxophora, Abdomen tubular and elongate, much curved down- 

 wards, so that the whole bodj' seen in pi'otile forms nearly half a 

 circle. Lcqs with strong bristles behind hind femora in most 

 genera, but on apical half only in Toxophora ; there are some 

 exceptions. Tibias generally with conspicuous bristles or spicules 

 on hind pair. Wings with the 2nd longittidinal vein looped or 

 not near its end; two or tliree submarginal and three or four 

 posterior cells ; anal cell closed at some distance from the border 

 in Toxophora, open in some genera. Alulas and hind angle of 

 wing well developed in Toxojjhora, weak or absent in some genera; 

 squam.'c generally with only a slight fringe, but 'Toxophora has a 

 long rigid one. 



The principal characters of this subfamily are the structure of 

 the antennffi, the usually humped thorax, the long narrow abdomen, 

 and three posterior cells. The limits of the group are not well 

 defined, and the species all appear to be uncommon.
