SCIARA. 129 



at Kui-seong, Novembei- 1910, has a nearly black tliorax, but the 

 genital organs are reddish yellow as in normal specimens. 



Tifpe. The locatioii is unknown to me. 



The briglit yelhjwish thorax, the large yellowish genitalia of the 

 male, and the black body and wings, make this species easily recog- 

 nisable. The female is rather larger than the male. Van der Wulp's- 

 coloured plate is excellent, and de Meijere gives additional notes.. 



The fact seems to have escaped notice that the 1st longitudinal 

 vein is much longer in the female than in the male. 



80. Sciara rufoabdominalis, sp. nov. 



$ . Head black ; mouth-parts and scape dark reddish brown ; 

 (flagellum missing). Thorax, scutellum and metanotum shining 

 black; (scutellum crushed by pin). Abdomen and belly orange- 

 red ; base of 1st segment above, and whole of last segment, black. 

 Ovipositor small, black. Legs black, tibial spines pale. Wings 

 pale blackish ; 1st longitudinal vein ending much beyond fork of 

 4th, the branches of the latter subequai to the petiole in length, 

 parallel, rather curved ; the 2nd posterior cell four times as long 

 as wide. Halteres black. 



Length 5| millim. 



Described from one female in the Indian Museum from Ukhrul, 

 Manipur, 6400 ft. (Pettigrew). 



81. Sciara Inteiventris, sp. nov. 



2 . This species closely resembles the preceding one, but owing- 

 to its being only half the size, I do not like to consider it 

 identical. The first two dorsal abdominal segments are wholly 

 blackish, the 3rd and the apical two (mainly) also blackish, the 

 remainder yellowish or red. The abdomen seems more hairy. A 

 distinct difference in the wing is that the 1st longitudinal vein 

 only reaches the fork of the 4th, and the branches of the 4th,. 

 Avhich are slightly longer than the petiole, are nearly straight and 

 almost parallel, only diverging a little at the tips. The 2nd 

 posterior cell is four and a half times as long as broad. Halteres 

 black. 



Length 2^ millim. 



One female in the Indian Museum from below Phagu, 7000 ft.,. 

 Simla district, 12. v. 09 {AnnandaJe). 



82. Sciara flammiventris, sp. nov. 



9 . Head black ; scape bare of bristles, but flagellum normally 

 pubescent. Eye-facets whitish. Thorax dark blackish grey, 

 nearly bare, shoulders A^ery narrowly reddish ; with a black narrow 

 median line, on each side of which is a large velvet-black oval 

 outline, incomplete posteriorly ; anterior margin of dorsum also 

 blackish. Scutellum (broken by pin) and metanotum black. 

 Abdomen dull black, broad, the segments very distinct. Belly
