description of mosquito to be merely varieties of the cosmopolitan 
S. fasciata. 
Mosquito differs from the type fasciata in that the thorax is 
only marked by the semilunar, silvery, lateral stripes, and the 
scales of the mesonotum are rather more rusty-red (Fig. 50, 
PI. XIII.). 
In some specimens examined by a lens no traces of any other 
ornamentation could be found on the mesonotum, but on 
examining with a microscope, light scales might be seen indicat¬ 
ing the two thin parallel median lines of fasciata , in fact 
between the type and variety mosquito all stages could be found. 
Habitat .—This variety I have noted from St. Lucia, Jamaica, 
and Calcutta. 
Time of capture of “ mosquito .”—Jamaica and St. Lucia, July 
and August (2 p.m.). 
Observations.—C. mosquito has been rightly placed as a 
synonym of C. fasciatus. Desvoidy described it from Cuba, 
where it is very troublesome in the rainy season, and named 
“ mosquito ” by the natives. 
It is, like S. fasciata , an indoor species, being often found in 
bedrooms. Lewis refers to C. mosquito in India, in his paper on 
Filariasis in the Proceedings of the Asiatic Society of Bengal, 
1871, pp. 89-93. Giles thinks he referred to Skuse’s C. albo- 
pictus, which, as I have pointed out, is C. scutellaris, Walker. 
As this variety of fasciata occurs in India it is most probable 
that Lewis was quite right in his identity. 
The C. mosquito of Desvoidy is figured by Guerin and 
PercheroiTs “ Genera des Insectes,” Dipteres, pi. 2, and is a £ , 
but it shows all the legs banded with white, as is also stated to 
be the case in the subsequent description; possibly this figure is 
partly imaginative, for Desvoidy (Essai, p. 407), in his descrip¬ 
tion of the species, says, “ feet black, joints of fore tarsi with 
silvery bands,” evidently referring to some of the joints only if 
the feet are black, and this is what we find in fasciata and its 
varieties. 
It must not be confused with the Culex mosquito of Arri- 
balzaga, which is a typical Stegomyia fasciata.
