16. iv. 1909 (1000 ft.); South Coorg, S. India, 15-26. v. 1914 

 (FletcJier) ; Trincomali, 15. ix. 1890 ; and Mahaganj, Ceylon, 

 8.ii.l891 (Col. Yerhury). 



A conspicuoias species, resembling a llypendonia oE ray fourth 

 group (Kec. Ind. Mus. ii, p. 413). 



A single <S was taken by Dr. Annandale in company with 

 iiiveiventris $ , of which species I conclude it to be the S . The 

 Irons is barely appreciably narrower, therefore the narrowness of 

 the back of the head above, the difference in shape of the genital 

 organs, and the nearly clear wings are the onlj- points in which it 

 materially differs from the previously described species. 



Head ahnost exactly as in niveiventris, except that the tirst joint 

 of the antennte is pale, and the back part of the head is less puffed 

 out behind the eyes, where it is covered closely with very small 

 creamy-orange scales; mouth-border whitish, bare. Thorax dusky 

 olive-brown, with two faint but distinct, narrow, widely separated, 

 blackish lines ; anterior part and sides with pubescence as in 

 niveiventris, except that it is whitish below the posterior calli ; 

 scutellum as in niveiventris. Abdomen as in niveiventris. The 

 genital organ is concealed within the body, but is covered with 

 whitish shimmer and fine black bristles, its tip apparently con- 

 sisting of a pair of rather complex orange-coloured claspers, the 

 upper side of the tip being covered with thick, black, bristly 

 spines. Lecfs with the underside of the fore femora pale and the 

 spines below the hind tarsi less conspicuous. Winijs wholly very 

 pale gi'ey, including costal cell; the veins in the middle at the 

 base of the wings are pale orange, as are also the subcostal, third 

 and fifth longitudinals ; halteres cream-coloured. 



Length, 16 mm.

6 . Head : frons above antennae nearly one-third the width of the 

 head, lessening to one-third of that width at tl;e vertex, shining 

 black, with short black ])ubescence atid pale whitish-yellow scales 

 above the antennas and over the shining black face also ; these 

 scales show prismatic colours in certain lights ; antennas dark 

 brownish yellow, 3rd joint ending in a fine point; oral opening 

 whitish yellow, bare, or with a few very short pale yellow hairs ; 

 proboscis rather long, blackish ; palpi black, curved, very slender, 

 with short hairs ; occiput and underside of head black, a few 

 scales closely pressed to the surface, behind the eyes. Thorax 

 shining black, with milk-white bristly hairs on the sides, anterior 

 border of dorsum, and around the wings. vScutellum dull coffee- 

 brown, some small white scales below its hind margin, closely 

 applied. ^icZo>??<?H black, moderately shining, almost bare ; small 

 milk-white scales at the bases of the segments towards the sides ; 

 venter black, with the basal part of most of the segments covered 

 with small snow-white scales. Legs wholly black, except for a
