Described from a single perfect female in my own collection 

 taken by me at Mussoori, 18. vi. 05. 



223. Tipula nigrotibialis, sp. riov. 



<$ . Head : eyes considerably approximate, leaving a narrow 

 frons, which, with the vertex, is dark grey, both with a narrow 

 pale border. Proboscis dark yellowish brown, palpi darker, both 

 moderately pubescent. Antennae with the scape all yellowish ; 

 flagellum brownish yellow, verticillate, base of joints narrowly 

 black. Thorax : prothorax rather conspicuous (though normal in 

 size) owing to its detachment at the margin from the mesonotum ; 

 neck yellowish. Dorsuui of thorax grey ; a pair of median, 

 rather well separated stripes, reaching the anterior margin, and 

 the usual outer short stripes, all brownish grey ; the usual large 

 spots behind the suture present, but not very pronounced. Scu- 

 telluni and dorsum of metanotum dark brown ; sides of thorax 

 rather bright yellowish, sides of metanotum dark grey. Abdomen: 

 dorsum pale yellowish ; an elongated dark grey spot with parallel 

 sides on each segment (forming a dorsal stripe), widened on the 

 posterior margin, the extreme edge of which is pale ; a distinct 

 black lateral stripe ; the last two or three segments almost wholly 

 blackish. Genital organs of moderate size but very complex ; a 

 rather large dorsal blackish oblong plate, with black hairs on the 

 surface and edges, produced posteriorly into a narrow, elongate 

 yellowish piece, ending in two palp-like appendages ; basal joint 

 of claspers very large, dark brown, blackish at base, bearing three 

 pairs of appendages (1) a whitish, obtusely conical 2nd joint; 

 (2) a jointed obtuse piece ending in a long hard shining pointed 

 portion, black at the base, the remainder reddish brown ; and (3) 

 a ridge-like projection of the underside of the basal joint itself, 

 bearing dense yellow hairs ; a ventral plate, very conspicuously 

 keeled, enclosing yet another pair of clasper-like organs, thickly 

 pubescent at the tips. The 8th sternite itself is distinctly V- 

 shaped, bearing on each side of the angle of the V, near the hind 

 margin of the segment, an elongate patch of thick yellow hairs. 

 Legs : coxae and the major part of the femora yellowish ; femora 

 towards the tips becoming dark brown or blackish ; remainder of 

 legs dark brown, nearly black on the tibiae, tarsi a little lighter. 

 Wings : ground-colour moderately dark grey ; costal cell yellowish, 

 the colour extending to the stigma, which is sharply delineated 

 proximally by the " obliterative streak." The wing is much paler 

 (though in no part is it quite clear) on the basal half of, and 

 narrowly at the tip of, the 2nd basal cell ; at the tip of the 1st 

 basal cell and on a part of the marginal cell immediately above ; 

 also on the basal half (or thereabouts) of the discal cell. There is 

 a crescent- shaped pale spot at the base of the 2nd, 3rd, and 5th 

 posterior cells, and an elongate pale streak on the basal half of 

 the anal cell, with a smaller one just beyond the middle. Discal
