Two new Australian Diptera. 501 
blackish, the flagellum has the few basal joints yellowish 
brown, the remainder dark brown. Thorax entirely shining 
black, except for a narrow grey-pruinose band across the 
lower edge of the pleuize; scattered black hairs but no short 
pubescence on the mesonotum, which has a well-marked 
tubercle in the middle line in front. Abdomen nearly cylin- 
drical, entirely shining black. Legs: front coxe and all the 
trochanters reddish, middle and hind coxze shining black. 
Femora yellow with black tips; front and middle pairs 
entirely unarmed, hind pair with two bristly spines on the 
underside near the tip. Front tibie slightly enlarged before 
the middle, the basal half and the tip black, the remainder 
yellow. Middle and hind tibiz with the basal fourth and 
the tip black, remainder yellow. All the tarsi with the first 
joint yellow; second, third, and fourth brownish; fifth 
whitish, claws black. First tarsal joint of front legs a little 
less, of middle and hind legs rather more, than half as long 
as the tibia; second joint about half as long as the first, 
third about half as long as the second ; the front legs being 
shorter than the others, the third tarsal joint is almost 
globular. Fourth joint on all legs short, cordiform. Fifth 
joint about as long as the third, longer on the front lees, 
without spines beneath. Claws nearly as long as the fitth 
tarsal joint, simple; the front and middle pairs equal, the 
hind pair very unequal. Wengs slightly greyish, unmarked. 
Costa to about nine-tenths of wing-length; second marginal 
cell more than three times as long as first ; cubitus forking 
below base of lower branch of media. (Halteres missing.) 
Length of body, without antenna, 8 mm.; wing 2°5 mm. 
N. AUSTRALIA: Stapleton, 16. 11. 1915; two females (one 
damaged) taken in jungle amongst small herbage (G. F. 
Fill). 
This species is the first to be described from Australia of 
this group of Ceratopogonine ; it is chiefly interesting on 
account of its elongate antennze, with cylindrical flagellar 
joints ; the presence of spinules on the hind femora only is 
also a very unusual character, and, so far as I am aware, is 
found in only one other species—P. currier, Coq., from North 
America,—which, except in antennal characters, must bear a 
close resemblance to P. flagellata, ‘The bristles on the hind 
femora of the new species are hardly stout enough to be 
called spines, and doubt might arise as to whether the species 
should be placed in Palpomyia or Johannsenomyia, but tor 
the presence of a well-marked mesonotal tubercle. This 
tubercle has apparently been overlooked by previous workers
