THE CANADIAN ENTOMOLOGIST i59 



black hairs; mouth-parts and palpi dark brown. Antennic with the scape orange; 

 flagellum dark brownish black; flagellar segments slender, elongate-cylindrical, 

 with long verticils. Head orange; vertex between the eyes more brownish. 



Pronotal scutum dark brownish black; scutellum paler. Mesonotum deep 

 velvety black, the pra'scutum narrowly margined anteriorly with pale yellow; 

 lateral wings of the scutellum whitish. Mesonotum covered with an abundant, 

 short, subappressed pubescence. Pleura deep black, the dorso-pleural mem- 

 brane buffy-yellow; a large, circular, pale yellow area surrounding the base of 

 the halteres. Halteres dark brown, the base of the stem narrowly pale. Legs 

 with the outer faces of the coxae blackened; trochanters yellowish testaceous; 

 femora dark brownish black, paler basally; tibiae brown, the tips darker; tarsi 

 brownish black. Wings subhyaline, the costal and subcostal cells scarcely 

 brighter; stigma elongate, brown; veins dark brownish black, slender but clearly 

 defined; an obliterative area before the stigma, continued across the basal 

 deflection of 3/i+2 and the outer deflection of Mz. \'enation: Rs moderately 

 long, slightly arcuated at origin, a little shorter than i?2+3; deflection of R.^^^ 

 and r-m in alignment; m-cit obliterated by the very short fusion of Mi and Cn\. 



Abdomen broken, only the terminal six segments preserved, the fourth 

 to seventh deep velvety-black, the eighth and ninth reddish horn colour. Ovi- 

 positor with the tergal valves slender, curved slightly ventrad; sternal valves 

 much shorter, the apices obtuseh- rounded. 



Habitat. — Uganda. 



Holotype. — 9 , Ankole-Toro Border, east of Lake George, altitude 4,500 

 feet, October 20-21, 1911, (S. A. Neave). 



Presented by the Imperial Bureau of Entomology, 1915-57. 



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



The opaque black mesonotum without markings and clothed with an 

 abundant, nearly appressed pubescence, gives this handsome fly a very character- 

 istic appearance. 



Tipula ruwenzori, sp. n. 



General coloration black; head orange-red; mesonotal pnescutum shiny 

 yellow with three very broad, black stripes; postnotum light yellow; abdomen 

 brownish black. 



Female. — Length 18 mm.; wing 16.8 mm. Fore leg, femur 9.8 mm.; tibia 

 11.4 mm. Hind leg, femur 11. 1 mm.; tibia 12.8 mm. 



Somewhat similar to J", neavei but readily distinguished as follows: Antennae 

 shorter. Mesonotal praescutum shiny yellow with three broad. shin\- black 

 stripes, only the narrow interspaces and the humeral and lateral margins being 

 of the ground colour; scutum and scutellum entirely black; postnotum with 

 the median .sclerite conspicuously light yellow, the extreme caudal margin 

 narrowly darkened. Pleura entirely dark brown, the mesepimeron with an 

 indistinct yellowish cast. Wings slightly more brownish, especially the costal 

 and subcostal cells; veins with short but conspicuous macrotrichia>. \'enation: 

 section of vein .M\^i between r-m and m strongly arcuated; petiole of cell Mi 

 about equal to m; fusion of Ms and Cu\ very slight, less than one-half r-m. 



Abdomen dark brownish black, without definite marks of paler, the genital 

 segment and ovipositor reddish horn-colour.
