316 GNATS OR MOSQUITOES — CHAPTER XII 



on the terga of the abdominal segments and the fact that the antennal 

 joints are densely clothed with white scales almost to the end of the 

 appendage, may possibly prove to be of generic importance. In such 

 case the new genus, which might perhaps be named Leptocornis, would 

 include, in addition to the present species. An. ocellatus, and A71. 

 jjharosnsiti with its new variety, An. albofiinbriatas. Length. — 3 mm. 



Habitat. — Taipang, Perak, Straits Settlements (L. Wray, November 

 22nd and December 21st, 1899). 



" Observations. — A very distinct and beautiful pale species, easily 

 told by the two clear, dark, eye-like spots on the thorax, the dark area 

 of the scutellum, and the much banded legs and tarsal markings. 

 Described from two $ 's only." 



28. ANOPHELES GIGAS, sp. n. 



Plate X, lig. 2a, Wing of $ ; 2b, Wing of S • 



Wing with the costa black, interrupted by a comparatively 

 small, fulvous spot opposite the basal half of the anterior fork- 

 stem, in addition to which there is a large apical spot, and the 

 base of the wing is generally pale, except the actual base of the 

 costa, which has here a black length cut in two by a minute 

 white dot, so that the general appearance is that of two large 

 black, triangular ai-eas, with their bases on the costa, the inner 

 part of the wing being mainly pale, with but few black vein- 

 spots; the internal fringe is pale at the apex and generally 

 towards the base, and the intervening dark portion shows pale 

 patches at the longitudinal junctions. In the <? , the whole wing 

 is much lighter, there is an additional light spot near the apex, 

 and the entire fringe is yellow. Thorax of a deep chocolate- 

 brown ground colour, the dorsum covered with a velvety, greyish 

 bloom, so arranged as to leave bare a median and a pair of 

 lateral darker lines. Abdomen dark brown, with some lighter 

 hairs, and showing on the terga some lighter tomentum, like 

 that on the thorax. 



2 . — General coloration, deep chocolate throughout, the head with 

 the vertex and frontal tuft yellowish ; autennie two-thirds the length of 

 the proboscis, wliich is distinctly longer than the quite unhanded palpi. 

 Halteres with pale stems and dark knobs. 



J . — Altogetlier hgliter, the palpi golden-brown, with dense terminal 

 tufts of hairs to the joints, about equalling the proboscis in length. Most 

 of the upper tarsal joints show (juite distinct lighter yellow apical bands, 

 though they are quite imperceptible in tiie $ . His fore ungues, besides 

 the usual accessory tooth, have a strong additional one close to the base, 

 representing probably the other claw, which appears wanting ; those of 

 the mid and hind legs are simple and symmetrical. Length. — 9 to 10 

 nun.
