Ninth tergite of male (fig. 5) broad, pointed, rather shining 
apically, tip with a single blunt median tooth. Pleurites _ 
thick, clothed with dense black hair; claspers (fig. 6) almost 
hidden by the projecting pleurites. Ninth tergite of female 
(fig. 7) broadly and deeply emarginate ; anal valves very 
short, fleshy ; valves of ovipositor very short. The abdomen 
in both sexes is short and rather stout, that of the female 
being rather broader but not longer (in proportion) than that 
of the male. Legs blackish, slender, the first tarsal joints 
not much longer than the tibie. Wings slightly and uni- 
formly infuscated ; stigma distinct, yellowish brown. Tip of 
R, present, but uncoloured. Rs short, less than twice as long 
as the stigma, twice as long as Rg, or Ry, and about equal 
in length to R3. R3 and Ry,5 nearly straight, the latter 
ending just above the wing-tip. Basal deflection of R,,; 
very short, shorter than the R-M cross-vein. Cell M, 
almost parallel-sided, nearly three times as long as its petiole. 
A short M—Cu cross-vein present. Cell Ax broad, broadest 
in middle, extended a short distance beyond tne base of the 
basal cells. 
Length of body 11 mm.; abdomen 6 mm.; wing, ¢ 15, 
° 17-5 mm:

This is one of the most strikingly coloured species of 
Tipula I have seen, and it is surprising that it should not 
have been described before. Its only near allies seem to be 
T. melanomera, Walk., from Nepal, 7. cinereifrons, de Meij., 
from the Malayan region, and the new species described 
below. Both the former have an entirely reddish thorax. 
‘These four species form a very distinct group, distinguished 
by the short stout abdomen and the remarkable female hypo- 
pygium, with its short fleshy anal valves and its very short 
ovipositor. (The anal valves in most species of Tipula form 
the ensiform appendages, which are usually spoken of as the 
dorsal valves of the ovipositor.) It might be justifiable to 
remove these species from Tipula; but, as I can see no 
character, apart from those of the genitalia, on which to base 
a generic distinction, I refrain from doing so. 
Tipula rufizona, sp.n. (PI. XII. fig. 8.) 
A single female specimen in the British Museum Collection 
from Chin-Fu-San, W. China (W. A. Maw), represents a 
species which is evidently closely allied to ZT. rufomedia, but 
is certainly quite distinct. It differs from 7. rufomedia as
