second, its base much nearer the wing base; posterior cross-vein shorter 
than median about one-and-half times its length distant from that vein. 
Coxae light or dark brown according to age of mosquito. A patch of creamy 
scales on the anterior face of the fore coxae and a few scales near the base 
of mid coxa ; femora covered above with dark brown scales ; beneath they 
are silvery-brown, this being least marked on the fore legs most marked on 
the hind legs; at the apex of each is a ring of creamy scales especially 
well-marked on the hind femora. Tibiae dark brown scaled with rows of 
pale golden spines. Metatarsi and tarsi scaled dark brown but under a 
2/3 power the scaling towards the ends of the tarsi looks paler and more 
of a coppery-bronze. Fore and mid ungues very clumsy equal and 
uni-serrate. Hind equal and simple. 
Abdomen .—In the living specimen curved upwards especially at the 
apex. Clad with metallic-purple-bronze scales above. At the base of 
each segment is a large patch of pearly-white scales. Ventrally each 
segment is basally banded with pearly-white scales though owing to 
retraction this is only imperfectly seen in a dry specimen. The penul¬ 
timate segment is much expanded apically like a bell the genitalia 
corresponding to the clapper. 
Occurrence .—Described from a series of females some hatched from 
larvae found in a small jungle pool some caught as adults. 
Remarks .—The scaling of head thorax and scutellum resembles that of 
other species of this genus but the wings are more heavily scaled and the 
lateral scales are broader than in any other species. The larva certainly 
resembles that larva of A. Varietas, but the discovery of a male may prove 
it a member of the sub-family Culicinae. It is sylvan and a vicious day 
biter. 
Genus 5. — Acalleomyia. —nov. gen. 
Head clothed with flat scales over most of its surface with narrow- 
curved ones behind. Scutellum with flat scales and six border bristles j 
mesothorax with curved hair-like and narrow-curved scales ; metanotum 
nude. Fork cells moderately long ; first sub-marginal cell longer than the 
second posterior cell; many of the lateral vein scales long and broad. 
Acalleomyia Obscurus. n. sp. 
A mosquito of medium size with pale colourless pleura with black 
scaled legs and abdomen; dark slate spatulate scales on the head with a 
few narrow-curved ones behind and numerous upright scales. Scutellum 
with spatulate scales. Prothoracic lobes and pleura without scales. 
Female Head. —Slate-grey, covered with dark slate spatulate scales with 
rounded ends over the whole of its surface except for a margin of light-grey 
scales along the eyes which is ill-marked at the vertex but becomes broader 
and more distinct laterally; on the nape scattered amongst the broad scales 
are some dark grey narrow-curved scales covering a patch roughly trian¬ 
gular ; several rows of dark grey almost black upright forked scales are 
present and a few extend as far forward as the vertex. The head scales 
shew purple and blue tints in certain lights. Basal joint of antenna dark 
slate, hairy, but without scales, remaining joints dark slate except for a 
small colourless band at the insertion of each verticil. There is a fairly
