Observations : Described from two perfect specimens ; 
Dr, Bancroft states that they live in company with Uranotsenia 
pygmsea ; although very distinct they cannot be told from 
that species until boxed. An extremely rare mosquito found 
just before leaving Deception Bay in 1904, in a cask half-ful of 
water resting just above the water line;.

Mr. Theobald in the Vol. IV. Monograph of Culicida?, re-

it necessary to add a figure showing the different parts, that are

important to notice. Roughly, the external genitals^ consist 
of two " claspers," each of which has a large basal lobe [(bes,) 
and a variously shaped terminal clasp segment (tes), which 
folds over like the blade of a knife. At the apex of this is found 
a more or less developed spine (this may be absent in some species, 
double in others), which is thought by Professor Felt to be the 
rudiment of a ventral second segment analogous to the claspette 
(c) of the basal segment. The term claspette designates certain 
peculiar organs occurring on the ventral surface of the basal 
lobe, it may be represented by one or more spined tubercles
