downwards, the second long vein is curved downwards and then 

 upwards, so that the cell is large in the middle, contracted at 

 each end ; scales broad. 



Two $ 's so far are known in this genus, which is very 

 distinct, the squamose characters are very marked and the palpi 

 quite different to any others.*

"d. Head light, heavily covered with light yellow, almost white 

 iridescent flat scales, a few brown forked scales on the occiput extending 

 well around to the sides ; two large bristles projecting forward between 

 the eyes, four or five around the eyes; antennae brown, very plumose, 

 light banded, basal segment bare, dark, verticels brown, but giving light 

 (tow-coloured) reflections with a suggestion of orange ; proboscis orange, 

 tip black ; palpi longer than the proboscis, mostly yellow scaled ventrally, 

 but partly brown scaled dorsally, a dark band at the apex of the 

 penultimate segment, ultimate segment clubbed (suggesting something 

 of the Anopheles) and quite dark at the tip ; clypeus yellow ; eyes brown 

 and silver. 



Thorax : dorsum dark brown, heavily covered with dark brown slender 

 curved hairs, laterally light, covered with light golden curved scales, 

 forming a large spot over and around the wing joint and running in 

 a line cephalad on the edge of the mesonotum, light bristles over wing 

 joint ; pleurae and prothoracic lobes almost white ; scutellum dark brown, 

 median lobe, and light lateral lobes, both covered with dark brown slender 

 curved scales, six large and a few small bristles on the mid lobe, four 

 bristles on the lateral lobes; metanotum dark brown. Abdomen light, 

 thickly covered with dark brown flat scales, having deep blue iridescence ; 

 very large basal lateral light spots forming an almost continuous lateral 

 yellowish stripe, also continuous with the venter, which is very light 

 yellow, almost white. All segments heavily haired. 



Legs: coxae and trochanters all light. In fore legs the femora are 

 brown dorsally and ventrally light yellow, growing darker towards the 

 apex, tibiae brown (giving red-bronze and purple lights), first tarsal brown, 

 with tiny light apical bands, tarsal segments brown, second and third also 

 with light apical bands. Ungues unequal, very large, one bi-serrate, the 

 smaller almost straight. Mid legs much as in fore legs ; there are tiny 

 light bands on the first, second and third tarsal segments, and in some 

 lights the whole first tarsal looks light. Ungues as in the fore legs. 

 Hind legs have femora brown, with red reflections, tibiae brown with
