XIPHOLIMNOBIA, gen. nov. 
Antenne with 16 segments, those of the flagellum elongate- 
oval with moderately long verticils. Tibiz without spurs ; 
claws small, simple. Wings with numerous macrotrichie 
on the distal two-thirds of the veins, lacking on the veins 
proximad of the basal third of the sector, except a series of 
about 11 that occupy the distal two-thirds of vein 2nd A ; 
Sc. at the tip of Sc,;; tip of vein R, entirely atrophied; cell 
M, lacking ; basal deflection of Cu, at about three-fourths 
the length of cell Ist J;. Ovipositor with the valves 
exceedingly long and slender, nearly as long as the entire 
remainder of the abdomen. 
Genotype.—Xipholimnobia terebrina, sp. n. (Western 
Ethiopian Region). 
The new genus Xipholimnobia is based on a single small 
species, in which the valves of the ovipositor are of a length 
that is unequalled, proportionate to the size of the fly, in 
any other known crane-fly. This condition of the terebra 
probably indicates a highly specialized habit of oviposition, 
but this is at present unknown. ‘The position of Sc, at the 
tip of Sc, is an uncommon character in the tribe Hriopterini. 
Xipholimnobia terebrina, sp. n. 
General coloration brown ; wings light brown, Sc. at the 
tip of Sc,; tip of 2, beyond r atrophied ; basal deflection of 
Cu, at about three-fourths the length of cell lst M,; valves 
of the ovipositor very long and slender, nearly as long as the 
remainder of the abdomen taken together. 
Female.—Length 3°6 mm.; wing 3°6 mm.; ovipositor 
alone ]*4 mm. 
Rostrum and palpi dark brown. Antenne long for this 
sex, if bent backward extending beyond the wing-root, dark 
brown, the first scapal segment paler; flagellum with the 
segments elongate-oval, the terminal segments elongate- 
cylindrical; flagellar segments provided with long con- 
spicuous verticils that are much longer than the segments 
that bear them. Head brownish grey. 
Pronotum dark brown. Mesonotal prescutum shiny 
testaceous brown. Pleura yellowish testaceous. Halteres 
pale brown, the knobs slightly darker. Legs with the coxe 
and trochanters pale testaceous ; remainder of the legs light 
brown. Wings with an almost uniform light brown suffusion ; 
stigma lacking; veins pale brown; macrotrichie confined to 
the veins beyoud the level of the origin of Rs excepting a
