566 APPENDIX. 



Genitalia in both sexes small, reddish yellow. Legs pale brownish 

 yellow, femora a little lighter, the tips a little irregularly obscured. 

 Wings nearly clear, with a ground- work of very small and ex- 

 tremely pale grey spots, mainly circular or roughly quadrate, and 

 more or less arranged in longitudinal rows ; a few darker spots 

 along the costa, a rather larger blackish darkening over the 

 marginal cross-vein, contiguous to a small ill-defined stigma, and 

 weak, but obvious, slight infuscations over the forks of the veins, 

 the " cross" veins (speaking broadly), and the tips of most of 

 the veins in the distal part of the wing. Halteres small, pale 

 yellow. 



Length 5 1 millim. 



Described from a unique pair from Pattipola, Ceylon, 6000 ft., 

 14. x. 11 (Annandale). 



Types in the Indian Museum. 



This species is distinguished from D. marmoripennis, Brun., by 

 the entirely dark sides of the thorax, instead of the conspicuous 

 whitish grey sides with a broad dark lateral stripe, as in that 

 species. 



Dicranomyia bicinctipes, sp. nov. 



tf. Head brownish yellow, antennae and palpi dark brown. 

 Thorax rather more arched than usual, brownish yellow, with a 

 pale median line from about the middle of the dorsum, carried 

 continuously across the scutellum to the rear of the meta- 

 notum. Sides and underside of thorax pale whitish yellow, a 

 brown stripe between and across the anterior coxae. Abdomen 

 dark brown, the posterior part of many of the segments paler. 

 Belly wholly whitish yellow ; genitalia brown, apparently of 

 normal structure. Legs pale brownish yellow, tips of femora and 

 two narrow rings on the tibiae, black ; these rings situated just 

 before the first and second thirds respectively ; tarsi snow-white ; 

 tibiae becoming white towards and at their tips. Wings cuneiform, 

 pale grey, iridescent. Auxiliary vein endingabout half-way between 

 the origins of the 2nd and 3rd longitudinal veins ; stigma large, 

 oval, black, well defined ; discal cell absent ; upper branch of 4th 

 longitudinal vein forked at one-third of its length, the veinlets 

 parallel ; posterior cross-vein in a line with the base of the 3rd 

 posterior cell ; the endings of the 2nd, 3rd, and 4th longitudinal 

 veins approximately parallel. Halteres dirty yellow, tips darker. 



Length 5 millim. 



Described from three males in the Indian Museum from 

 " Thingannyinaung to Sukli," Dawna Hills, 900-2100 ft., 

 23-27. xi. 11 (Gravely). 



This species belongs to what may be termed the saltans group ; 

 those with cuneiform wings and snow-white tarsi, the Thrypti- 

 comyia of Skuse.
