SCIAKA. 141 



the front margin, is a little longer than the other two stripes. 

 The 5th vein forks at a very distinctly greater distance from its 

 base than in flavicollis, in which species the anterior branch is 

 apparently disconnected at the fork. 



Leiujih 3^ millim. 



Described from two males in the Indian Museum from Darjiling, 

 1 . x. 08 (type) and 2. x. 08, also a male in my collection from the 

 same locality, 10-16. x. 05 ; all three specimens taken by me. 



In all other respects, except that the antennal scape is yellow, 

 this species is identical with flavicollis. Although the resem- 

 blance is so close I feel sure that the forms are distinct, and 

 tend to indicate that too much reliance must not be placed 

 on the precise mathematical point reached by the 1st longitudinal 

 vein. 



101. Sciara segmenticornis, sp. nov. 



cJ . Head blackish. Palpi, scape and 1st flagellar joint pale 

 yellow, 2nd joint brownish yellow, remainder dark brown, with 

 grey pubescence, each joint with a short transparent bare part at 

 the base, which gives the appearance of the joints being detached 

 from one another. Thorax moderately shining light brown. 

 Abdomen dark brown ; belly a little lighter. Genitalia concolorous, 

 normal, moderately large. Legs pale yellowish, tibiae and tarsi 

 only slightly darker. Wings very pale yellowish grey, iridescent ; 

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

 at about the middle of the wing ; petiole of 4th vein longer than 

 the branches of its fork, which are slightly convergent in the 

 middle. Halteres black, stem yellow. 



Length 2 millim. 



Type cf in the Indian Museum, from Bindukhera, Nairn Tal 

 district, in the plains, 13. iv. 09. 



A second male in the same collection from Darjiling, 29. v. 10, 

 taken by me, is probably the same species, but has the whole 

 flagellum black. It is slightly larger in size. 



102. Sciara compacta, sp. nov. 



$ . Body mainly light brownish yellow. Head with the vertex 

 blackish ; flagellum blackish, except the two or three basal joints. 

 Thorax with the shoulders and scutellum paler yellow. Abdomen 

 more brownish, the tip black ; ovipositor concealed. Legs : tibiae 

 dirty yellow, tarsi black. Wings with "the 1st longitudinal vein 

 ending distinctly before fork of 4th and exactly at middle of wing ; 

 branches of 4th nearly as long as petiole, parallel, a little curved. 

 Halteres blackish brown, stem yellow. 



Length 2| millim. 



One example (type), from Gangtok, Sikkim, 6150 ft., 8.ix. 09 ; 

 and a second from Butal, Nepal, 12.ii.08, this latter being a little 

 more brownish in colour. Both in the Indian Museum.
