Legs. — Coxse rather pale brown, with some moderately long 

 and thick greyish hair. Femora concolorous with scattered grey- 

 ish hairs. Tibiae pale yellowish brown, with short black spines 

 and a circlet of them at the tip, which is slightly darker. Tarsi 

 blackish, with some short black spines and microscopic black 

 pubescence ; base of metatarsi pale. 



Wing. — Quite clear, iridescent ; veins pale yellow ; tegul^ 

 pale yellow with short hairs. Halteres rather large and promi- 

 nent, egg-shaped, pale lemon-yellow, nearly white. 



Described from one cf (type of the species) in the Indian Mus- 

 eum, taken by Dr. Annandale at Lahore, 9-V08; also one d* and 

 several 2 $ in the Pusa collection from Bombay and Pusa at which 

 latter place it was bred (24-iv-o5) from caterpillars found under 

 the bark of the shisham tree {DMeygia sissoo, Roxb.). 



N.B. — This must be something like Macquart's australis, but 

 in that species, according to the plate, there is a wide, well-defined 

 grey border running round the front and sides of the thorax. 



Systropus nigricaudus, mihi, sp. nov. 



{Id. id., Bigot, nom. nui.) 



cf $ . W. Himalayas (Mussoorie). Long. 16 mm. 



Head. — Vertex reduced almost to a point. Kyes black, bare ; 

 contiguous for rather more than half the distance from the vertex 

 to the antennae, gradually diverging until at the mouth-border 

 they occupy nearly one-third the width of the head : facets small, 

 of uniform size, the frons and face combined appear as an isosceles 

 triangle, the inner portion being very deeply retracted, leaving a 

 broad white margin on the three sides. Above this the antennae 

 are placed on a slight yellowish white (almost quite white) promi- 

 nence, and from the cavity below protrudes the long black pro- 

 boscis, 3^ mm. long., which is brown at the base below. Antennae : 

 first joint white at the extreme base, becoming immediately pale 

 yellow, graduating into orange, which form.s the centre part, and 

 deepening into black for about the apical third ; the whole joint 

 with scattered short black spines ; second joint half the length of 

 the first, wholly black, closely covered with black spines ; third 

 joint all black, quite bare, slightly shorter than the first. Back of 

 head silvery white, with some short white hairs. 



Thorax. — Dorsum black, finely punctate, with very sparsely 

 scattered very short golden yellow hairs. Two rather narrow 

 central grey stripes close together run from the anterior margin 

 to the middle where they coalesce, and continue, united to the 

 posterior margin. These stripes are only visible when viewed from 

 behind. On the shoulders are placed three calli, the upper and 

 largest one being almost bisected, the intermediate one very small 

 and triangular, the lower one as large as the upper and also trian- 

 gular. The upper one is contiguous to a more or less oblong spot 

 on the dorsum, directed inwards and backwards ; the remaining
