deeper golden yellow and the wings are practically clear. In all 
other respects it agrees absolutely when placed side by side with a 
European specimen of Meigen’s species. 
Chrysopilus maculipennis, Walk. 
(Redescription.) 
?. Borneo. Long. 6 mm. 
Head.—Blackish grey ; frons + to + the width of the head, 
with a distinct median groove; ocellar triangle concolorous, dis- 
tinct Proboscis blackish grey, labella arge, conspicuous, brown- 
ish yellow, a little pubescent; palpi black, pubescent. Antennae 
blackish grey; Ist joint nearly bare, 2nd with a few stiff black 
hairs, 3rd with soft grey hairs, arista long, black, microscopically 
pubescent. 
Thorax.—Ground colour blackish; originally undoubtedly 
covered with bright golden yellow pubescence (greatly denuded in 
the present specimen). The surface is also clothed with small 
bright emerald green scale-like hairs, which also extend over the 
scutellum. Sides grey, pleurae with a rather bluish grey tinge. 
Scutellum black, brownish yellow on hind margin. 
Abdomen blackish; posterior margins of segments with a 
moderately broad, yellowish brown, well-defined band, apical seg- 
ments yellow, genital organ blackish, elongate. 
Legs.—Fore coxae yellowish, posterior coxae blackish grey ; 
femora brownish yellow, tibiae blackish yellow, tarsi black. 
Wings.—Very pale grey, with blackish grey markings, in a 
general way resembling my C. marmorvatus. Stigma black but not 
distinctly defined from the transverse median band that runs from 
the costa to the hind margin of the wing, gradually diminishing in 
width, embracing the base of the upper branch of the 3rd longi- 
tudinal vein, the distal third of the discal cell, crossing, in 
narrowed width, the 4th posterior cell, widening abruptly behind 
the last branch of the 4th longitudinal vein. A narrower band of 
similar colour and irregular width begins at the base of the 2nd 
longitudinal vein, crossing the anterior cross vein, the basal third 
of the discal cell, the posterior cross-vein, following the 5th longi- 
tudinal vein to the wing margin, and filling nearly the apical half of 
the anal cell. A third band begins on the costa near the wing 
tip, moderately broad, passing over the sub-marginal cell, which 
it fills, with the exception of the extreme base and tip, joining the 
median band proximally. Beyond the lower branch of the 3rd 
vein it abruptly becomes very narrow, and passes over the middle 
of the 2nd and 3rd posterior cells in widened form. The wing 
immediately in front of the stigma is distinctly yellowish. 
Halteres yellowish. 
Redescribed from a single 2 in the Indian Museum, perfect 
except for the denudation of the thorax. It was taken at Mujang, 
Sarawak, by Mr. C. W. Beebe, 12-Vvii-r10.
