5 , Head : eyes almost contiguous ; occiput aucl frons grey, 

 antennae also; palpi more or less blackish. Thorax brownisli 

 grey, apparently variable in shade ; a wide median stripe from 

 anterior margin, of varying intensity ; two shorter adjacent but 

 not contiguous side stripes, of less distinctness, and a large more 

 or less dark oval spot on each side behind the transverse suture ; 

 the depressions in the dorsum pale yellowish. Abdomen blackish 

 or dark brown, ovipositor reddish yellow. Legs brownish yellow ; 

 femora and tibiae barely darkened towards the tips, knees pale, 

 tips of tarsi darker. Wings very pale grey ; subcostal cell a little 

 yellowish ; the 1st longitudinal vein yellowish, with four very 

 narrow but distinct black marks, placed approximately equi- 

 distantly : the first over the humeral cross-vein, the fourth over the 

 origin of the 2nd vein ; there is a fifth, at the tip of the auxiliary 

 vein, the base of the 3rd vein also being just perceptibly iufus- 

 cated. Venation normal ; halteres brownish yellow. 



Length 5| millim. 



Described from three females from Peradeniya, Ceylon, 

 22. vii. 10 {tiipe), 7. ii. 10 and 3. x. 10 {E. E. Green). 



Type in the Indian Museum. 



This species is closely allied to D. suhfascipcnnis, Brun., and 

 imnctidata, Meij. 



Dicranomyia approximata, sp. nov. 



$ . Head: dark grey, antennae brownish yellow, palpi blackish. 

 Thorax: dorsum rather bright shining yellowish, bare; scutellum 

 and metanotum concolorous ; sides pale yellowish. Abdomen 

 moderately dark brown, practically bare, emarginations of 

 segments a little darker ; belly pale yellowish. Ovipositor large, 

 basal part pale yellowish, upper pair of valves brown, lower pair 

 black at base, tips reddisli yellow. Legs long ; femora brownish 

 yellow, with blackish tips ; tibiae and tarsi darker brown. Wings 

 pale yellovvish grey, vitreous ; stigma distinctly brownish, of 

 moderate size, but not sharply defined. Auxiliary vein ending a 

 little beyond origin of 2nd longitudinal vein. Venation normal ; 

 halteres small and slender, black. 



Length 5 millim. 



Described from a single male in the Indian Museum from 

 Ghumti, Darjiling district, 4000 ft., vii. 1011 (F. H. Gravely). 



This species comes near D. cinerascens, Brun., being dis- 

 tinguished by the entirely yellow (not grey) thorax ; by the more 

 jellowish femora; and by the auxiliary vein ending distinctly 

 some little distance beyond the origin of the 2nd longitudinal 

 vein, whilst in cinerascens it ends exactly opposite the origin of the 

 2nd vein. There is also no suspicion of the slightest infuscation 

 over any of the veins, whereas in cinerascens there is often a 

 tendency to this.
