new or little-known Tipulide. 469 
hypopygium with the armature unusually developed even for 
a member of this genus ; three powerful chitinized appendages 
on either side, the longest and most powerful of which is 
enlarged apically into a two-edged complicated head.

Flolotype, 8, Olama, altitude 2000 feet, July 24, 1919 
(J. A. Reis). 
CERATOLIMNOBIA, gen. nov. 
Vertex behind the antennal bases with a flattened white 
lobe or cornicle. ‘Tibize unspurred. Wings with Se long, 
Sc close to the tip of Se, ; tip of 2, atrophied or nearly so ; 
cell 1sé M/, closed ; basal deflection of Cu, before mid-length 
of cell 1st M,. Male hypopygium small, with two pleural 
appendages, the longest recurved into a U, at the bend of 
which is a cylindrical minutely branched arm. 
Genotype.— Ceratolimnobia munrot, sp. n. (Southern Ethio- 
pian Region). 
By means of all existing keys to the Tipulide this crane- 
fly would run to the genus Gnophomyta, to which it is 
obviously not closely allied. Gnophomyia is gradually 
becoming a receptacle for many diverse Hriopterine elements, 
and it seems advisable to remove the present fly from such 
an incongruous gathering and erect a separate genus for it. 
The presence of a snowy-white corniculus, much as in the 
Kthiopian species of the genus Ceratocheilus, Wesché, offers 
the most ready means for distinguishing this genus from 
similar crane-flies. 
Ceratolimnobia munrot, sp. n. 
Head light grey, with a snowy-white cornicle on the 
vertex ; general coloration dark brown, the mesonotal pre- 
scutum narrowly margined laterally with silvery white ; legs 
dark brown, the tips of the femora and tibie narrowly white, 
the fore tarsi largely white ; wings dusky, the costal region 
more yellowish, with six large dark brown blotches; veins 
beyond the cord broadly seamed with brown. 
Male.—Length about 2°77 mm. ; wing 3°8 mm. 
Rostrum and palpi black. Antenne with the scapal 
segments black ; flagellum broken. Head with a light grey 
pubescence, the middle of the vertex and the postgense more 
blackish ; on the fore part of the vertex immediately behind 
the antennal bases and between the anterior end of the eyes
