 Ovipositor of female small, simple, brown. Legs : coxje and femora 

 pale yellow, latter with a small black spot below at base ; tibiae and 

 tarsi brownish, the latter darker. Winc/s pale grey, iridescent ; 

 1st longitudinal vein ending much before fork of 4th and distinctly 

 before middle of \\ ing ; petiole of 4th about equal to branches, 

 which gently diverge ; 2nd posterior cell a little over three times 

 as long as broad. Halteres yellow. 



Length l|-2i millim. 



Described from a type male, Darjiling, 2. x. 08 (Brunetti), and a 

 type female, Darjiling, 6. viii. 09 (Paiva), and a second female, 

 Kurseong, 3. ix. 09 (Annandak) ; all in the Indian Museum. 



112. Sciara evanescens, sp. nov. 



(3* 5 . Head black, palpi yellowish. Thorax black, shoulders a 

 little yellowish. Dorso-central and lateral bristles moderately 

 large. Scutellum black, -with two long bristles. Abdomen blackisla 

 brown, hind margins of segments a little blacker. Genitalia in both

 Legs pale yelloAvish ; tibiae a very little darker ; tarsi dark browm. 

 Wings nearly clear ; in certain lights with brilliant violet irides- 

 cence ; 1st longitudinal vein ending distinctly before fork of 4th, 

 barely reaching middle of wing ; petiole a little shorter than the 

 branches of 4th, the latter gently diverging; 2nd posterior cell 

 three times as long as broad. Halteres yellow. 



Length 2 millim. 



Described from six males and three females in the Indian 

 Museum ; the type male from Simla, 9. v. 09 {Annandale) ; the type 

 female from Calcutta, 25. ii. 09 (Annandale) ; other specimens from 

 Darjiling, 6. viii. 09 (Paiva), and Peradeniya, Ceylon, 14. vii. 10, 

 7. viii. 10. 



Under the present species are grouped a number of specimens 

 which show considerable similarity, but which, on further study of 

 a larger amount of material, may prove to comprise more than one 

 species. But for the much shorter 1st longitudinal vein, these 

 insects might almost be united with S. orientalis, and in any case 

 their natural affinities appear to be certainly with that species. 



113. Sciara parallela, sp. nov. 



S 5 . ffead black, except the yellow palpi and the basal part 

 of the first flagellar joint of the antennae. Thorax black, 

 shoulders yellowish ; with traces of dorso-central and some lateral 

 stiff hairs. Scutellum brown, yellowish below, with four long 

 apical bristles and some shorter ones ; metanotum blackish ; sides 

 of thorax blackish. Abdomen hlackish brown or dark brown, hind 

 margins of segments more or less pale, and on the belly also. 

 Ovipositor concolorous, of considerable size, the basal joint being 

 nearly as large as in the males of many species ; the second joint
