new and little-known Tipulide. 255 
minal segment rather narrowly red at the base ; lam. term. 
wf. of hypopygium of different shape and differently toothed. 
Though at first sight this might easily be mistaken for 
Es ctenophorina, it differs considerably in the genitalia and 
also in the shining thorax, the long hair on the hind femora, 
and the narrow white rings on the tibie. 
Pselliophora ctenophorina, Riedel. 
1 $, Kuskus, 25. v. 1908 (I. Nitobe); also 1 g in 
British Museum from Koannania, 8. Formosa, 15, vi. 1906 
(A. H. Wileman). 
The Kuskus specimen agrees very well with Riedel’s 
description (Ent. Mitt. ii. 1913, p 274), except that the last 
Joint of the palpi is white with the tip black. In the Koan- 
nania specimen the palpi are missing, but the wings are 
yellowish brown as described by Riedel for the female of 
Ps. ctenophorina. In both these specimens the thorax and 
the tip of the abdomen are dull black, a point of some im- 
portance not mentioned by Riedel. 
Pselliophora semirufa, sp. u. 
Head velvet-black, antenne and palpi black (last joint of 
palpi missing). None of the antennal joints are distinctly 
enlarged on the underside; the third joint is about as long 
as the first, the fourth half as long as the third and a little 
longer than the fifth. Zhorax uniformly velvet-black. 
Abdomen with the first three segments entirely reddish 
orange; middle part of fourth sternite and a rather broad 
narrowly interrupted basal band on the fourth tergite of the 
same colour ; remainder of fourth and the whole of the fifth 
to eighth segments velvet-black ; ninth segment and ovi- 
positor shining black. Legs black; hind femora orange on 
the basal third; front and hind tibiz with a narrow white 
band near the base (middle legs missing). Wings blackish 
brown ; a yellow area across the bases of the basal cells, 
divided by the dark veins which cross it ; two large some- 
what oval yellow spots, almost united, occupying the apical 
third of the basal cells, the upper one extending into the 
inner marginal cell; a small yellow streak below Cu, ; 
whitish patches i in the centres of cells An and Ax. Cell M, 
just sessile; Cu, rather strongly curved downwards at the 
tip, so that at the wing-margin the cell M; is twice as wide 
as the cell Cu,. Halteres black, base of stem brownish. 
Length of body 17 mm.; wing 17 mm.
