very long and sub-equal, the last two also sub-equal, but very short ; 

 entirely black except the last joint, which is snowy. Antennae quite as long 

 as the proboscis, the hairs of its verticils exceptionally long and dense. 

 The knee spots are barely perceptible, but each femur shows a distinct 

 broad white garter UtpiffKeKis) about a quarter from its tip. Pleurse 

 with snowy spots ; halteres entirely pale. Scutellum with pale brown

Plate xvi, fig. la, Venation of (J wing ; lb, The same, more amplified to 

 show distribution of dark and light scales. 



Wings densely clothed with, for the most part, black scales, but 

 on the costa and along the bases of tlie long veins, are scattered 

 snowy scales. Tarsal joints moderately broadly basally banded 

 with snowy white, on all of the hind, the upper three of the 

 mid, and the upper two of the joints of the fore leg. Thorax, 

 black-grounded, clothed with narrow curved, mouse-coloured 

 scales, with some whitish ones laterally which form indistinct 

 curved markings. Abdomen sooty, with snowy lateral spots on 

 the bases of the segments, which in the $ , especially on the 

 anterior segments, may be connected to form narrow bands. 

 Proboscis banded in the 3 , but not distinctly so in the ? . 



Head, with black forked scales, and mouse-coloured long narrow ones. 

 AntenniE fuscous, those of the <? about equalling the proboscis in length. 

 Palpi of ? black, with whitish tips ; of the male, very little longer than 

 the proboscis, first joint minute, second and third sub-equal, and together 

 near as long as the proboscis, with an indistinct band on the articulation 

 between them, placed a good deal inside the band on the proboscis ; last 

 two joints short and sub-equal, a band between them and the third, and 

 all the end joint, whitisli. Proboscis black at the base, testaceous at the 

 tip, with a broad band of white, well beyond the middle, in the <? , but 

 barely perceptible in the ? . Legs with a patch of white scales just above 

 the tips of tlie femora, in the 3 . but not in the ? . The wings, legs and 

 all other appendages are most curiously brindled with a mixture of snowy 

 and black scales, the latter greatly preponderating, so that the insect 

 looks peppered and salted. No otiier mosquito at all likely to be 

 mistaken for this species , has this mixtvu-e of white with black scales on 

 the wings. Leiuith.- About 3 mm. 



Ha/^i/a/. —Jhansi, Gonda, N.W. Provinces, India.
