SIX NKW SPECIKS OF OULICID.F. FROM INDIA. 195 



proboscis in the male, black with black verticils ; in the female the 

 internodes are covered with whitish down ; on the upper surface of the 

 basal joint is a patch of whitish scales ; second joint short. Proboscis 

 sooty black throughout. Palpi of male but four-fifths the length of 

 the proboscis, tapered, their terminal joints much the smallest in all 

 dimensions ; black, saving a few scattered yellowish hairs on the 

 second joint, and a very minute yellow ring at the base of the second ; 

 in the female they are very minute, and have also a few scattered 

 yellow hairs on the apex and base of the penultimate joint. Thorax 

 covered with golden tomentum, through which the bare black ground 

 shows to form black lines. On the anterior two-thirds is a large 

 triangular golden area, divided into lateral halves by a delicate median 

 black line ; behind and external to this is a fairly broad V-shaped 

 black mark, the limbs of whicli taper off in front, and at the back of 

 the thorax laterally is yet another pair of somewhat reniform bare 

 black marks ; the golden scales are narrow and hair-like throughout, 

 and behind develop into bristles, which project backward from the 

 border of the metanotum in three strong tufts. The pleurae and coxfe 

 show a few patches of silvery scales, and there is a strong tuft of 

 yellow hairs at the root of the wings. Wings dusky, the veins densely 

 clothed with linear sooty-black scales. Axillary vein joining the 

 costa midway between the supernumerary cross-vein and the base of 

 the anterior fork-cell ; supernumerary and middle cross-veins joining 

 at a very open angle, placed a little outside the tip of the sixth longi- 

 tudinal, and almost twice the length of the distinctly longer hinder 

 cross-vein external to it ; anterior fork-cell longer and somewhat 

 narrower than the posterior ; their stems about equal, the stem of the 

 anterior being just half the length of its cell. Halteres with white 

 stems and black knobs. Legs sooty black throughout, save for the 

 golden lower surfaces of the femora ; a distinct knee spot and a few 

 stray bristles of the same colour on the other joints. In the male the 

 anterior and middle legs have strong symmetrical tarsal claws, each 

 with two accessory spines ; those of the hind legs are small, sym- 

 metrical, and simple. Abdominal segments black, with narrow snowy 

 basal bands, consisting of a pair of crescentic spots narrowly connected 

 across the middle line, the hinder and lateral borders of the segments 

 showing some golden hairs. Ventrally the abdomen is elaborately 

 adorned, each of the five middle segments showing behind a large 

 lunate golden area, bounded in front by a narrow sooty line which 

 touches the segment in front of it in the middle line, and so separates 

 a pair of triangular snowy patches at the sides of their bases ; the 

 anterior and hinder segments are almost purely white. Length of 

 proboscis 3 mm. ; of male palpi 2-6 mm. ; of antennas 2 mm. ; of 

 wing (female) 5 mm. 



Hah. Naini Tal. Is essentially a sylvan species, though I 

 have taken a specimen in the verandah. The larvfe are found in 

 pools in the course of the (perfectly clean) fresh water surface 

 drainage system, through which in heavy rain a perfect torrent 

 of water flows. They are darkly tinted, about 8 mm. long when 

 mature, and have a short spiracle, no longer than the last two 

 abdominal segments, and but little longer than the anal papillae.
