set with microscopic black spinulae. Outer dististyle broad, the apex obliquely truncated to 
feebly concave. Inner dististyle with the lower apical angle produced into a slender curved rod, 
the tip blackened and acute. 
Hab. Burtetan Coneo (Kivu). 
Holotype, aleoholic #, Kabara Camp, on southwest slope of Mt. Mikeno, 
altitude 10,500 feet, in subalpine zone (Hagenia formation), March 16, 1927 
(J. Bequaert). Paratopotypes, 4 33. 
Tipula speiseriana is named in honor of Dr. P. Speiser, distinguished stu- 
dent of the Diptera of Africa. The species seems intermediate in its charac- 
ters between 7. soror Wiedemann and 7’. frater Alexander, with short yellow 
antennae, and 7’. ewmecacera Speiser and 7’. capnioneura Speiser, in which the 
antennae in the male sex extend to beyond the base of the fifth abdominal 
segment. It is very possible that the present species will be found to have 
subapterous females as is the case with several species of Tipula from the high 
mountains of equatorial Africa. 
Tipula (Acutipula), species 
Females of two distinct species, from Moala, thirty miles from the coast, 
north of Monrovia, Liberia, and from Paiata, on the St. Paul’s River, eighty- 
five miles from the coast, northeast of Monrovia, Liberia, October 10, 1926 
(J. Bequaert).

The type, a female, was from Mt. Ruwenzori, collected at 3,000 meters, 
April 15, 1914, by Dr. Bequaert. Numerous additional specimens were later 
recorded from Uganda and Kenya Colony, at altitudes of between 3,500 and 
8,000 feet. In the present collection, a male, from Kabale, Uganda, was taken 
in the cultivated lower mountain zone, at 6,500 feet, by Dr. Bequaert. This 
specimen agrees well with the type except that the bases of abdominal seg- 
ments two to four are orange-yellow. The prothorax and mesothorax are 
blue-black, entirely without pale colors other than a vague reddish suffusion 
on the postnotal mediotergite. 
Nephrotoma chalybea Alexander, variety 
1921. Nephrotoma chalybea Alexander; Ann. Mag. Nat. Hist., (9) 7: 101-103. 
A male from Kisenyi, on the northern shore of Lake Kivu, 1° 35’ 8., 29° 15’ E., 
in lower mountain forest at 4,400 feet. This agrees well with the type except 
that the blue-black coloration of the thorax and abdomen is unusually devel- 
oped. 
Nephrotoma fuscipennis triflava Alexander 
1921. Nephrotoma fuscipennis triflava Alexander; Ann. Mag. Nat. Hist., (9) 7: 107. 
A male from Kisenyi, north shore of Lake Kivu, February 10, 1927 (J. 
Bequaert).
