438 Mr. F. W. Edwards on 
whole body long, pale yellowish ; wings quite unmarked. 
Eyes rather small, rounded, widely separated. Proboscis 
very short, much shorter than the head. Palpi very long, 
the joints straight and rigid in appearance, fourth joint as 
long as the first three together. Antenize sixteen-jointed, 
scapal joints small and rounded, flagellar joints cylindrical, 
the first about six times as long as broad, second scarcely 
four times, the following joints to the fourteenth (last) very 
slightly shorter; the last joint with a constriction just before 
the tip. Thorax with long pubescence, but less dense than 
in Bruchomyia. Postnotum and pleure bare ; metanotum (or 
metapleuree immediately above the halteres) with rather dense 
Paleosycorax molophilina, sp.n. Wing, x 40. 
tufts of long pubescence. Male hypopygium exserted, con- 
spicuous, but its structure obscured ; there may be one or 
two pairs of claspers (pleural appendages), one is rather elon- 
gate, finger-like, with a short basal projection which is fringed 
with black hairs; the tip is only very slightly hooked, not 
strongly so as shown, in Meunier’s figure of the hypopygium 
of P. tertiarie ; the greater part of the clasper is blackened, 
but the base is pale. Anal cerci of female flattened, fleshy 
and hairy, rounded at the tips and not quite as long as the 
last abdominal segment ; genital valves of ovipositor short, 
bluntly pointed. Coxe moderately elongate (as in Brucho- 
myia) ; femora and tibize moderately hairy, the tibize slender, 
considerably longer than the femora, apparently quite spurless ; 
tarsi missing (except base of metatarsi). Wing-veins clothed 
with long hair except on the cross-veins and the basal part 
of Cu,; microtrichia small but distinct over the whole surface ; 
fringe long, especially on the hind margin towards the base. 
Se reaching only one-third of the wing-length ; Sc; distinetly 
present, vertical. Rs arising beneath the middle of Se, forking 
below tip of Sc; R,,3 a little longer than Re; Ry.; forking 
before middle of R,,3; R; converging slightly towards R, 
at the wing-margin. 7—-m rather more than its own length
