Genus Stegomyia. 
by American observers is Wiedemann’s taeniatus, so Professor 
Howard writes me ; and as there is only one species of this 
kind found in the West Indies, I feel sure that taeniatus , Wiede¬ 
mann, must sink as a synonym of G. fasciatus, Fabricius. 
Wiedemann’s 0. taeniatus was described also from evidently 
rubbed specimens (A. Z. I. p. 10). His description of the thorax 
is as follows : “ The denuded thorax of the males brown, of the 
undenuded 9 >s brownish, with three brown stripes, the middle 
one linear and smaller, the suture snow-white on either side.” 
In all other respects the description agrees with the cos¬ 
mopolitan species received at the Museum, the ornamentation 
of the thorax, as in numbers of specimens I have seen, being 
very easily destroyed. Wiedemann himself suggested that his 
taeniatus might be no more than a variety of Fabricius’ species. 
Wiedemann’s specimens came from Savannah. 
Variation of the species .—There is much variation in this 
species, both in size and colour of the thoracic scales. In this 
way no doubt some confusion has arisen, but after examining some 
hundreds of specimens I can detect no structural difference in 
those from various parts of the world. Dr. Bancroft sends 
some from Queensland under the name C. Bancroftii, which have 
certain peculiarities in some specimens, such as the thoracic 
scales being golden-brown and the abdomen with apical yellow 
bands, all stages existing from one or two yellow apical scales to 
distinct bands; this is described as a distinct variety ( Queens - 
landensis). 
Others occur, such as mosquito , Luciensis, &c., referred to in 
the following pages. Such numbers of this species have been 
received that I may have overlooked a few that are separate.

var. mosquito. R. Desvoidy. 
(Fig. 50, PI. XIII.) 
There is little doubt in my mind, after examining a large 
number of specimens, that Desvoidy’s Culex mosquito is only 
a variety of C. fasciatus. From St. Lucia, Calcutta, &c., 
numbers of specimens in excellent condition have been received 
which answered to Desvoidy’s description of C. mosquito ; 
but variation of the thoracic markings in all degrees could 
be found, hence I take the species that answer to the
