1004 REPORT OF THE HARVARD AFRICAN EXPEDITION 
THE CRANE-FLIES 
(Famity Trpunmpar, ORDER DrpTERA) 
By Cuartes P, ALEXANDER, AMHERST, MASSACHUSETTS ! 
The crane-flies that were taken on the expedition of the Harvard Medical 
School to tropical Africa in 1926-1927 have been sent to me for determination 
by the collector of the material, Dr. Joseph Bequaert, to whom I extend my 
deepest thanks. Several of the species proved to be new to science, while still 
others added materially to our rather scanty knowledge of distribution of the 
Tipulidae of the Ethiopian Region. The most interesting series were those 
taken in Liberia, especially at Firestone Plantation No. 3, on the right bank 
of the Du River, ten miles east of Monrovia, and the small but highly inter- 
esting series from the volcanic cones of Mikeno and Karisimbi, in the eastern 
Belgian Congo. Through the kind interest of Dr. Bequaert, the types of the 
novelties are preserved in my collection. 
TIPULINAE 
Tipula speiseriana, new species 
Belongs to the oleracea group; general coloration yellow and dark brown; antennae approxi- 
mately as long as the combined head and thorax, the outer segments dark brown; wings broad, 
the whitish subhyaline area in the radial field reaching the wing-margin in cell Rs; vein R3 long; 
male hypopygium yellow. 
Male. — Length about 17-18 mm.; wing 19-20 mm.; antennae about 6 mm. 
Described from alcoholic specimens. 
Frontal prolongation of head brownish yellow; nasus elongate; palpi dark brown, the apices 
of the individual segments somewhat paler. Antennae of moderate length, in the male approxi- 
mately as long as the combined head and thorax; scape obscure yellow; basal flagellar segments 
brownish yellow, the outer segments bicolorous, the basal enlargement being darker brown than 
the remainder of each segment; outer segments uniformly dark brown; longest verticils subequal 
to the segments; terminal segment very reduced. Head grayish, the front and narrow posterior 
orbits paler. 
Mesonotal praescutum obscure brownish yellow, the disk almost covered by three dark brown 
stripes, the median stripe entire; scutal lobes extensively dark brown; a dark median triangle 
behind the suture; scutellum dark, with a capillary darker brown median vitta; parascutella 
pale; postnotal mediotergite grayish brown with a median dark brown vitta, the lateral margins 
pale. Pleura chiefly yellow, the ventral sternopleurite and meron infuscated. Halteres elongate, 
dark brown. Legs with the coxae chiefly yellow, the outer face of the middle coxae infuscated; 
femora and tibiae brownish yellow, their tips darkened; basitarsi yellowish brown, the tips darker; 
remainder of tarsi black; legs long and slender; claws small, simple. Wings broad, tinged with 
brown, variegated with darker brown and whitish subhyaline longitudinal stripes; the white areas 
include an extensive stripe in the radial field, including most of the outer portions of cells R and 
M and all of cell R; to the margin; bases of cells Cu and {st A similarly whitened; costal margin 
yellowish brown; stigma and a broad seam in cell M along Cu, and on m-cu, darker brown. Vena- 
tion: R; unusually elongate, nearly straight, approximately four times Ri +.; cell 2nd A broad. 
Abdominal tergites yellowish brown, with three brownish black stripes; sternites yellowish 
brown, the median line darker, the outer segments more uniformly darkened; hypopygium bright 
yellow. Male hypopygium with the tergite bearing the usual two truncated lobes, these densely
