new and little-known Tipulidae. 257 
these specimens, and that the least perfect, was seen by 
Osten-Sacken. All three show the following differences 
from Walker’s species :—The wings are broadly yellow near 
the base, the yellow colour extending to about a third of the 
wing-length along the costa, though not so far along the 
hind margin; the extreme wing-base, however, remains 
black ; the tibia are much more brownish, so that the white 
rings are much less clearly defined—in fact, in two of the 
specimens they are practically absent. In the male the 
femora as well as the tibize are for the most part yellowish 
brown, as is the central axis of the antenne. he third 
antennal joint of the female is not distinctly produced below. 
The wing-markings, apart from the basal yellow patch, are 
rather more developed than in the most strongly marked 
specimens of Ps. fumiplena. Halteres light brown (¢) or 
blackish (?). 
Pselliophora sackent, sp. n. 
Two males and a female labelled ‘ China” (Bowring) were 
briefly described by Osten-Sacken (Berl. ent. Zeitschr. xxx. 
p- 171), who somewhat doubtfully regarded them as a 
variety of Ps. fumiplena. 
Head dark brownish, with yellowish-brown hair; antenne 
reddish, except for the appendages of the male flagellum, 
which are blackish. Thorax: prothorax wholly or partly 
brownish orange. Mesonotum brownish orange, with a 
narrow blackish-brown border; scutellum blackish brown. 
Postnotum mainly brownish orange. Pleure blackish brown, 
with one or two brownish-orange spots. Abdomen: first 
segment black ; second to seventh segments each orange with 
a black triangle on the posterior margin, that on the second 
segment rather small, the rest larger, and except that on the 
third segment reaching the anterior margin. Hypopygium 
mainly brownish orange, the tip blackish. Legs: coxa 
partly blackish, especially the front half of the hind pair, 
otherwise brownish orange; femora, tibiew, and first tarsal 
joints entirely orange, except their extreme tips, which are 
blackish ; the bases of the tibiz are somewhat lighter, but 
without distinct pale rings ; remainder of tarsi dark brown. 
Wings as in Ps. flavibasts, but the yellow at the base extends 
halfway along the costa. /a/teres rather light brownish. 
Brunetti’s Ps. bifascipennis, described from a female from 
Shangliai, is evidently related to this species, but has brown 
stripes on the mesonotum.
