150 THE CANADIAN ENTOMOLOGIST 



of the median area; scutellum and postnotum obscure brown; a slightly darker 

 brown spot on the lateral sclerites of the postnotum above the base of the halteres 

 Pleura indistinctly marked with pale brown and whitish. Halteres light brown, 

 the base of the stem and the knobs conspicuously light yellow. Legs with the 

 coxa^ and trochanters yellow, the outer face of the middle coxa infuscated ; femora 

 yellow, a little brightened immediately before the broad, black tips; tibiae 

 obscure yellow, the tips narrowly and indistinctly darkened; tarsi light brown, 

 passing into darker brown at the tips. Wings grayish subhyaline, sparsely 

 marked with brown and variegated with hyaline; costal cell slightly more yel- 

 lowish, the subcostal cell brownish yellow; stigma brown; conspicuous brown 

 seams at the origin of Rs; along the cord in the bases of cells R3 and R^; com- 

 pletely surrounding cell 1st M2 and at the fork of ikfi+2; deflection of Cui broadly 

 seamed with brown; a large brownish area near the arculus in the bases of cells 

 R and AI; a large obliterative streak along the cord, extending from before the 

 stigma, across cell 1st M2 into the base of cell Mi; smaller hyaline areas beyond 

 the stigma, in the bases of cells Mi and 2nd M'>; and two others in the end of 

 cell 1st A, one adjoining vein 1st A, the other nearer the 2nd Anal vein; veins 

 dark brown. Venation: somewhat as in T. jocosa, differing as follows: Rs 

 longer, a little longer than R2+S; base of R2 before r longer, apex of R2 beyond r 

 long and almost straight; cell 1st M2 roughly oval in outline, the basal deflection 

 of Mi+2 being shorter than the deflection of M3+4; M1+2 between r-m and m long, 

 evenly and gently arcuated; petiole of cell Mi shorter than m; m-cii short but 

 evident. 



Abdomen broken beyond the base, the first tergite brown, narrowly margined 

 caudally with yellow; base of the abdomen filled with large eggs. 



Habitat. — British East Africa. 



Holotype. — ^cf, Southeastern slopes of Mt. Kenya, altitude 6,000-7,000 

 feet, February 3-12, 1911, (S. A. Neave). B. M. No. 1912-70. 



Type in the collection of the British Museum (Natural History). 



Tipula masai is told from the related T. jocosa and T. silinda by the dif- 

 ferent pattern of the posterior sclerites of the mesonotum. From jocosa it is 

 also readily told by the yellow antennee and very distinct venation. The 

 coloration of the mesonotal postnotum is sufficient to distinguish T. silinda 

 from T. masai. The three species here mentioned form a group of rather closely- 

 related forms that are readily told by their peculiar thoracic pattern and yellow- 

 knobbed halteres. 



Tipula bartletti, sp. n. 



General coloration reddish brown, the procscutal stripes nearly concolorous, 

 narrowly margined with dark brown; scutellum and postnotum largely brown; 

 a small, brown spot on the sides of the prsescutum and on the lateral sclerites 

 of the postnotum; wings brownish yellow, the costal region darker; fusion of 

 Mz and Cih punctiform. 



.Sf-x-^— Wing about 25 mm. Hind leg, femur 1(5. 1 mm.; tibia 16.5 mm. 



Head destroyed by pests. 



Pronotum yellow, indistinctly infuscated on the sides. 



Mesonotal pra^scutum reddish brown with four almost concolorous stripes 

 that are narrowly margined with dark brown; median stripe narrowly split by
