observations : " Very like and closely related to N. annul ipes, 
but the female can easily be told by the proboscis being paler at 
the tip. It is also smaller in size, and Skuse says that the sub- 
costal transverse vein is placed considerably beyond the middle 
of the auxiliary vein, whilst in N. annulipes it is situated in the 
middle. 1 1 
These characters, however, I find will not hold with the 
Queensland specimens. 
TOXORHYNCHITES. — Theobald (1901). 
Head clothed with flat scales ; thorax with small, flat, 
spindle-shaped scales ; abdomen with flat scales. Palpi short in 
the ? three-jointed, the last joint long and rounded at the end, 
slightly curved at the apex ; long in the $ five- jointed ; proboscis 
long and curved, as in Megarhinus ; wing venation much as in 
Megarhinus, the supernumerary cross- vein nearer the apex of the 
wing than than the mid cross- vein ; ungues of ? equal and simple. 
Abdomen with a caudal tuft. In Megarhinus the palpi are long 
in both sexes 
Toxorhynchites speciosus. — Skuse (1888). 
$ . Antennae brown, a little more than half the length of the 
palpi ; basal joint black, with hoary reflections ; second joint 
more than twice the length of the third, ornamented with some 
beautifully iridescent scales, the whorl of very long hairs situated 
about one- third from the apex. Head covered with brilliant 
margaritaceous scales, chiefly reflecting green ; in a certain light 
appearing brown with a bright pale greenish line round the 
hinder border of the eyes. Proboscis (0.300in.) somewhat longer 
than the palpi (0.285in.), deep metallic blue, with a purplish 
reflection before the bend, brown beyond. Palpi deep metallic 
blue, with purplish reflections, the third joint ringed with golden- 
yellow at the apex (this is much more distinct underneath), and 
the fourth joint with a broader ring of the same beyond the middle. 
Thorax brown, the lateral margins and prothorax densely covered 
with pale greenish scales, the latter with long brown hairs ; hinder 
margin and scutellum richly adorned with brilliantly iridescent 
scales and long brown hairs ; pleurae "with a naked brown stripe 
from the origin of the wings to the scale-like prothoracic pro- 
jection, below this densely covered with silvery scales; metanotum 
brown, naked. Halteres ochre-yellow. Abdomen about twice 
the length of, but narrower than the thorax, flat, deep metallic 
blue, except the first segment, the latter green with a yellow patch 
on each side ; fifth segment showing some golden-yellow laterally, 
sixth and eighth segments ornamented with a strong tuft of 
golden hair laterally, the seventh with black tufts ; all the seg- 
ments slightly bordered with golden hairs laterally ; the first to 
third and fifth to seventh segments golden-yellow beneath with
