A NEW GENUS OF CULICID^E. 55 



$ . Head black, clothed with small flat black scales, and a border 

 of similar white ones around the eyes, which show pale-blue reflec- 

 tions in certain lights under the frd power, in front between the eyes 

 projects a tuft of very long white scales, 

 there are also scattered small upright 

 black forked scales and a small basal 

 medial blue patch ; antennae deep brown, 

 basal segment black, base of second seg- 

 ment reddish-brown ; palpi very small 

 black-scaled; proboscis black, a large 

 silvery-white patch towards the base, 

 and a smaller one on the dorsum nearer Fore ungues of AnisocheUomyia 

 the apex. Thorax deep brown, with alboannulata, n. sp. 



narrow-curved bronzy scales, a narrow 



white border around the front and sides of the mesonotum composed 

 of broad curved scales, which appear pale-blue in certain lights, ending 

 about the roots of the wings ; scutellum deep brown, clothed with 

 small flat deep brown scales, very distinctly trilobed, the mid-lobe 

 large with four border-bristles ; chsetre of mesothorax and scutellum 

 black ; metanotum black ; pleurae brown, with a narrow wavy white- 

 scaled line running along it from the base of the abdomen to the head, 

 and a few white puncta near the base of the legs. Abdomen black 

 and silvery-white, the first segment mostly white-scaled, the second 

 and third with a white median patch, the fourth all white, the fifth 

 black with a few apical white scales, the sixth all white, the apical one 

 black and white. Fore legs deep brown with a white spot at the apex 

 of the femora and a trace at the apex of the tibire ; mid legs with two 

 white femoral spots and silvery-white venter to femora ; hind legs 

 with femoral spots more pronounced ; tibiae with broad white median 

 and apical bauds ; metatarsi and tarsi with broad white apical bands 

 except the last two tarsi, which are all white ; ungues unequal, one 

 on each fore and mid leg very broad and curved, a thin web-like 

 membrane between the curved outer portion ; hind not examined, 

 wings ornamented with black and white scales much as in the former 

 species, but there are two dusky areas across the surface. The stem 

 of the second long vein close to the first, almost fused with it ; stem 

 of the first posterior cell nearly three times as long as the cell ; stem 

 of the second not quite twice as long ; scales on the stem of the fourth 

 rather long and broad, longer than in the former species ; posterior 

 cross-vein longer than the mid, about one and a half times its own 

 length distant from it. Black scales on the stem of the first fork-cell, on 

 the basal half of the third, some on the base of the stem of the second 

 fork-cell, on the greater part of the upper branch of the fifth, a few at 

 the apex of the lower branch, and a batch near the base, also some 

 near the base of the fourth. Halteres with testaceous stem and fuscous 

 knob. Length 2-5 mm. 



Habitat. India (Capt. James, I.M.S.). 



Observations. — Described from a single specimen. The species 

 is a very beautiful and marked one, and cannot be confused with 

 any other mosquito. The structure of the ungues is very
