22 STRATIOMIIPJE. 



yellow. Thorax and abdomen shining black, with short, sparse, 

 silvery grey hair, which is a little thicker and mixed with gold 

 hairs on dorsutn of thorax ; abdomen uniformly black. Leys pale 

 yellowish white, tips of tarsi faintly blackish. Wings quite clear ; 

 veins on anterior part and the stigma pale yellowish ; halteres 

 white. 



Length, 2-2 1 mm. 



Described from four 2 9 in the Indian Museum from Calcutta. 



My original description was insufficient, and my not noting the 

 unforked 3rd vein probably prevented de Meijere from recognising 

 my species in his infurcata, described from Java. The white tomen- 

 tose stripe on the side of the thorax mentioned by de Meijere is 

 present, though liable to be not readily distinguished from the 

 general whitish pubescence of the pleurae. 



3. Zabrachia annulifemur, sp. nov. 



J $ . Head shining black, bare ; frons at level of antennae about 

 one-fifth of the head in d 1 , in $ one-fourth width of head, sides 

 parallel except near vertex and towards antennae ; visible only 

 from above, a pair of moderate-sized oval silvery-white spots 

 placed lengthwise, nearly contiguous, one above each antenna ; 

 face with broad white-dusted band contiguous to lower inner eye- 

 margins. Antennas brownish orange, upper side of 3rd joint 

 blackish at tip. Thorax, scutellum, and inetanotum shining black, 

 all with very short whitish pubescence ; scutellum produced 

 upwards into a short blunt cone. Abdomen shininsr black ; dorsum 

 and venter with similar pubescence to that of thorax, but less 

 obvious ; genitalia brownish orange, with a few stiff hairs. Legs 

 yellowish, front coxae more brownish at base ; all femora with a 

 broad blackish ring leaving base broadly, and tips narrowly, pale. 

 Wings colourless, veins and stigma pale yellow ; halteres yellowish, 

 clubs shining milk-white. 

 Length, barely 3 mm. 



Described from three tf rf in the Pusa collection (including 

 type sent to British Museum) from Annandale, Simla District, 

 "on leaves," x. 1911 ; and one $ in the Indian Museum from 

 Simla, 7000 ft., 9. v.09 (Annandale}. 



This species must be near the femorata variety of de Meijere's 

 P. infurcata, but should be distinct. In P. albipes the <S frons is 

 one-sixth the width of the head, with practically parallel sides, 

 including the face also, there being only the very slightest widen- 

 ing towards the vertex and towards the mouth-opening. In the 

 $ the frons and face form one-third of the head, being distinctly 

 but slightly broader towards vertex and mouth. In P. annuli- 

 femur, $ , the frons is one-fifth the width of the head with less 

 parallel sides, and in the $ one-fourth. * These differences should 

 effectually separate the species and prevent the latter from being 

 confused with the femorata variety of infurcata, Meij.
