metallic blue, and the terminal one brilliant pale green. Coxae 
clothed with silvery scales. Femora and tibiae metallic voilet, 
the form.er golden-yellow beneath. In the intermediate and 
fore legs the first joint of the tarsi white except at the base, and 
the second also except at the apex ; the rest metallic violet. 
Wings longer than the abdomen, with a pale brownish tint 
anteriorly and along the fifth longitudinal vein, veins pale brown, 
cilia pale and short, weak reflections. Auxiliary vein joining the 
costa almost opposite but somewhat beyond the posterior branch 
of the fifth longitudinal ; sub-costal cross-vein distinct, situated 
about mid-way between the origin of the anterior branch of the 
fifth longitudinal vein and the origin of the second longitudinal ; 
fork of the latter very small, the tips of the branches slightly 
bent anteriorly ; supernumerary cross-vein equal in length to 
the middle cross-vein : posterior cross-vein more than twice the 
length of the latter, rather sinuose, tip of the anterior branch of 
the fifth longitudinal vein joining the margin opposite the middle 
of the second posterior cell, a very prominent wing-fold running 
close to the posterior side ot the fifth longitudinal for the whole of 
its length, and another on the anterior side in the anal cell. 
Skuse's description was made from damaged specimens.

This magnificent insect has a wide range, having beeu 
taken originally by Masters at Port Denison ; at Thursday Island 
by Mrs. Eyre ; at North Percy Island by Mr. Tryon ; and by 
myself in many scrubs from Caboolture to Moreton Bay and 
Enoggera. 
It is not a biting mosquito ; to obtain good specimens it is 
advisable to hatch out the larvae, which may be found in scrubs 
in crevices in trees holding a pint or so of water ; the larvae are
