282 A Monograph of Culicidae. 



base nearer the apex of the wing, its stem as long as the cell ; 

 stem of the second posterior nearly as long as the cell ; super- 

 numerary cross-vein a little in front of the mid, which is shorter 

 than either the posterior or supernumerary, the posterior also a 

 little in front of the mid, much longer than either of the others ; 

 halteres with ochreous stem, and fuscous knob with a line of 

 paler scales at the apex. 



Length. — 6 to 7 mm. ; length of hind legs 16 mm. 



Habitat. — Kuching, Sarawak (Dr. Barker, P.M.O.). 



Time of capture. — November. 



Observations. — This large handsome mosquito cannot be 

 confused with any other species. It varies to some extent in 

 regard to the amount of golden scales on the abdomen and the 

 spotting on the legs. 



Genus MEGACULEX. nov. gen. 



Head clothed with narrow-curved scales in the middle, the 

 flat lateral ones extending far on to the occiput, and numerous 

 upright forked scales ; palpi of $ rather long, more than one- 

 fourth the length of the proboscis ; antennae pilose in J about 

 as long as the proboscis ; plumose in the $ , scaly on the basal 

 lobe; male palpi long, with one short, rather swollen apical 

 segment; apparently only two-jointed. Thorax and scutellum 

 with narrow-curved scales. Wings with short fork-cells ; the 

 scales on the apical area of the veins large, pear-shaped, the 

 majority of the veins with a single median row of small spatulate 

 vein scales only ; stems of both fork-cells very much longer than 

 the cells. 



This genus is markedly distinct from any other. The short 

 fork- cells, wing scales, head scale ornamentation, longish female 

 palpi, long antennae, and peculiar male palpi at once separate it 

 from Culex. 



A single species so far only known, which was described from 

 a $ , and placed provisionally in Culex as C. albit arsis.
