latter towards the inner margin ; internal fringe dark, with the 

 apex yellow, and pale interruptions of the same tint at all but 

 the sixth longitudinal junction. Tarsi golden-brown, with mixed 

 golden and umber-brown scales, so arranged as to give faint indi- 

 cations of pale articular banding. Thorax (denuded) yellowish- 

 brown. Abdomen dusky, with some powdery whitish tomentum, 

 and numerous pale brown hairs.

 angular patch of broad, yellowish-white curved scales on the. vertex ; 

 nape with black curved, and erect forked scales ; palpi dusky at the base, 

 but for a narrow whitish ring on the second articulation ; the last two 

 joints impure white, rather darker on the articulation between them, and 

 just at the tip ; about as long as the proboscis ; antenniB black, with 

 scanty dark verticils and much white lanugo. Pleurae marbled with dark 

 and lighter brown. Halteres with pale stem and darker knob. Length

Habitat. — The Dowars, India. 



LIMATUS DURHAMII, Theob. gen. et. sp. nov. 

 (Monog. II, p. 349). 



This genus is allied to Trichoprosopon, the metanotum being 

 provided with bristles and scales, and is separated from its 

 neighbours by all parts being clothed with uniformly flat scales, 

 mostly rounded at their free ends. The proboscis is not very 

 long, but is much swollen at the tip, the ? antennas very small, 

 and with the usual single verticils. The venation of the wing is 

 much as in typical Culex. 



In the one known species the wings are unspotted, the 

 veins densely clothed with nearly black, round-ended scales, 

 some of those near the ends of the inner long veins being rather 

 elongated. Tarsi and legs generally, nearly black. Thorax 

 densely clothed with flat, round-ended scales of two sizes, mostly 

 of a lustrous violet-black, but with a marking of rich golden 

 scales in front, arranged so as to form a "broad arrow"; the 

 very large prothoracic lobes uniformly golden-scaled. Abdomen 

 metalhc-violet, with triangular basal lateral patches especially 

 well marked on the hinder segments ; the first segment mainly 

 ochreous. 



2 . — Head with dark bronzy and golden flat scales, white at the 

 sides; cephalic appendages, uniformly nearly black; the palpi appa- 

 rently three-jointed and very small, barely extending beyond the clypeus. 

 Scutellum densely covered with flat, purple scales and golden marginal 

 bristles ; pleural mainly silvery white. Metanotum golden brown-
