scutellum has many pale scales, the lateral lobes having them very 

 dense, black at the base, yellow at the apex. Antennae plumose, 

 with flaxen brown plume-hairs, palest at their base, proboscis 

 rather short, but not so thick as in the female ; palpi thin, acu- 

 minate, of four segments, the last two nearly equal, dark brown 

 with a basal pale band to the segments ; on hair-tufts, one or two 

 large chsetse. 



lyCgs as in the female, the narrow basal banding rather more 

 distinct, fore ungues very unequal, the larger with a large tooth, 

 the smaller thin and apparently simple, mid ungues equal and 

 uniserrate, hind absent.

^- •' v *Genus Radioculex, gen. nov. -' '■■"■ • '^ 



Head clothed with small flat scales and a group of upright 

 forked ones behind. Palpi of female thin, longer than in Culex, of 

 the male long, longer than the proboscis, composed of two segments, 

 the apical one short and clavate, with thorn-like chaetse ; proboscis 

 curved and swollen apically, shorter than the body ; antennae of 

 female pilose, of male densely plumose. 



Thorax and scutellum with narrow-curved scales, metanotum 

 nude ; blunt curved chsetae project over the head. 



Male genitalia with normal narrow claspers. Fork-cells small ; 

 the marginal cell of peculiar form in both sexes, swollen out in 

 the middle, contracted near apex of wing and widening again at 

 the apex ; scales large, median vein-scales single, small and 

 spatulate. 



A very distinct genus with shiny integument, especially on the 

 thorax, and easily told by the curious marginal cell and male 

 palpi.
