new Species of Pselliophora. 375 
coloured much as in P. nigribasis, but the black on the 
middle femora extends to two-thirds and on the hind femora 
to five-sixths of their. length. Wings entirely black, except 
for a small transparent streak in cell An. Rs with a trace 
of a spur; venation otherwise like P. nigribasis. Halteres 
black. 
Length of body 20 mm. ; wing 16°5 x 5°5 mm. 
BuRMAH (Cutter, 1868); 1 2. 
Comparable only with P. nigribasis. 
Pselliophora binghami, sp. n. 
Head dull orange ; last joint of palpi and flagellum of 
antenne entirely black. First flagellar joint as long as first 
scapal ; remaining flagellar joints close-set, convex beneath. 
Thorax uniformly orange, slightly shining. Abdomen orange; 
first segment black except at base and tip ; second, third, and 
sixth with velvet-black apical bands; 7 and 8 velvet-black ; 
9 shining black. Legs black; cox and trochanters orange ; 
basal two-thirds of front femora and underside of middle 
femora brownish orange ; all tibiee with distinct white basal 
rings, those on the hind tibize quite broad. Wings pale 
yellowish, theveins all dark brown; tip from the cord outwards 
dark brown, leaving the base of the discal cell and nearly the 
whole of cell 1; of the yellowish ground-colour ; hind margin 
(except in cell Cu,) slightly darkened. Rs not spurred ; cell 
M, rather broadly sessile ; cell Cu, nearly twice as broad as 
cell Cu, on margin ; m-cu punctiform. Halteres black. 
Length of body 16 mm. ; wing 14x 4 mm. ; 
BurRMAH: no exact data (Col. C. T. Bingham); 1 ?. 
Apparently nearly allied to P. ésshikii (Matsumura), but 
quite distinct. 
Pselliophora ophionea, sp. n. 
Whole body deep dull orange, excepting only the pectina- 
tions of the antenne, tlie tips of the lobes of the ninth tergite, 
the tibiee and tarsi, and the tips of the femora, all of which 
are black. Hind tibise with a very distinct pale ring close to 
base. Wings with membrane and veins orange, of a rather 
lighter shade than the body ; costa blackish except towards 
the base; a rather broad fuscous streak extending from just 
below the orange stigma obliquely to the hind margin at the 
tip of Cu, ; from this point to the base of the wing the hind 
margin is rather broadly fuscous. Pubescence of hind femora 
moderate, uniform. Hypopygium with the ninth tergite
