TIPULA. 325 



cell rather distinctly rectangular ; petiole of 2nd posterior cell 

 barely one-third as long as the cell. Halteres dark. 



Length (entire) 18 milliin. 



Described from two males taken by me at Darjiling, 28. v. 10. 



Type in the Indian Museum. 



The second example, though undoubtedly belonging to the same 

 species, has the thorax darker, and the blackish colour on the 

 abdominal segments spreads over more than the apical half, whilst 

 the legs are generally darker, especially the femora. In the wing 

 the apical half of the posterior cell is pale, and the parts of the 

 wing beyond the obliterative streak, towards the tip of the 2nd 

 basal cell, and a spot in the middle of the anal cell, are distinctly 

 darker brown. In the type these darker parts are clearly visible, 

 but to a less extent. 



This species is very near my T. quasimarmoratipennis, and they 

 might at first sight be regarded as male and female of the same 

 species. The differences, though not conspicuous, are quite con- 

 stant in all the specimens before me, and have every appearance 

 of being tolerably fixed characters. 



In T. nigrotibialis there is no trace of a dark grey spot over the 

 origin of the 2nd longitudinal vein, which is always present in 

 the other species. On the other hand, all the ground-colour of 

 the wing immediately beyond the obliterative streak, down to the 

 discal cell, is distinctly darker than the general ground-colour of 

 the wing ; whereas in T. quasimarmoratipennis there is a distinct, 

 nearly clear space immediately contiguous to the stigma. In the 

 latter species the posterior cells are wholly grey, without any 

 clear spots at the base, except where the obliterative streak some- 

 times encroaches on the base of the 1st or 5th cells. 



224. Tipula striatipennis, sp. nov. (PI. Y, fig. 16.) 



2 . Head rather dark ash-grey, shortly pubescent, with a median 

 fuscous narrow stripe on the frons, continued to the back of the 

 head. Antennal scape reddish yellow ; 1st joint of flagellum long 

 and black, next few joints reddish, remainder darker. Proboscis 

 and palpi dark brown, hairy. Thorax mainly (with the sides) ash- 

 grey, with short pale yellow hairs ; dorsum darker, with the median 

 dark stripe continued to the anterior margin ; the two side spots 

 smaller, narrow and well separated from the median stripe ; the 

 two post-sutural spots small. Scutellum and metanotum con- 

 colorous, with a narrow somewhat indistinct median dark line. 

 Abdomen light brown, shining, with pale yellow pubescence and 

 darker posterior margins to the segments ; 1st, 2nd, and part of 

 3rd segments lighter brown. Ovipositor bright reddish brown, 

 shining; the terminal points very narrow. Legs wholly dark 

 brown. Wings pale grey, with three obvious, but not sharply 

 defined pale brown bands and an apical darkening which is not 

 quite so distinct ; the 1st band is basal, and reaches to the oth
