and troublesome in Klang Jungle, and swarms in mangrove 
swamps. Three females only sent, no males. 
I cannot find any description that will at all apply to this 
small black mosquito, which is evidently very abundant in the 
jungles of Selangor. Its intense blackness, with the white 
lateral spots (that do not show on the dorsum), the narrow 
triangular second posterior cell, should at once make its identity 
easy. 
There is some slight variation, one species has the scutellum 
testaceous, in others the head ornamentation is more distinct, 
there appearing three clear pale lines, the lateral ones being 
oblique. Judging from the scale ornamentation, it is undoubtedly 
an Aedes.

the latter equal to about two-thirds the length of the cell;
