Genus Culex. 
47 
Observations .—A very distinct species, dull coloured in certain 
lights, with a broad band of light scales in the middle of the 
thorax and clear silvery-white spots at the sides, and similarly 
coloured beneath. Found at New Amsterdam on freshly-drained 
land and in houses (Rowland). 
One 9 from Rio de Janeiro differs from the rest in having 
the posterior cross-vein distant about its own length from the 
mid cross-vein. What remained of the legs also seemed paler, 
especially the femora, which had many white scales, except at the 
apex. The thorax had whitish scales in front, the back part 
being denuded, and the abdomen had a broad pale central mass 
of scales. It was taken by Senhor Moreira in November with 
the rest, and is probably only a colour variety.
