differs; unfortunately this was not examined in the English 
specimens. The pleurae of this species readily reflect any colour 
near them, those sent in pink-lined pill boxes had decided pink 
pleurae when pinned in the boxes. 
CULEX CYLINDRICUS. nN. sp. 
(Plates IX. and XII.) 
Thorax clothed with pale dull golden narrow-curved scales, 
unadorned. Abdomen black, narrow cylindrical, with six basal 
white bands, apex truncated. Legs blackish-brown, unbanded. 
9. Head brown, clothed in the middle with narrow-curved 
dull yellow scales, black at the sides and with a few flat white 
scales laterally, numerous narrow upright forked scales of a pale 
brown hue; palpi densely scaled with dark brown scales, with 
some long brown hairs; antennae brown; proboscis black, 
expanded apically. 
Thorax dark brown, when denuded, clothed with silky dull 
golden narrow-curved scales, and with two lateral rows of black 
bristles, numerous black bristles over the roots of the wings ; 
scutellum pale brown (almost testaceous when denuded) with 
narrow-curved pale scales and dark brown border-bristles, six 
large ones to the mid lobe and a posterior row of several very 
fine hairs ; pleurae slaty-grey and brown or bright brown with a

Abdomen narrow, cylindrical, slightly expanded apically and 
truncated, black, covered with black scales, the second to seventh 
segments with basal white bands, the scales rather more numerous 
in the middle of the segments, thus giving the bands a curved 
outline ; first segment testaceous with two median patches of 
dusky scales and numerous long brown hairs, apical segment black, 
bristly ; the antepenultimate segment rather expanded apically. 
Legs with pale brown coxae and trochanters almost grey in 
some specimens, testaceous in others ; remainder of legs deep 
brown, almost black, with bristles on the tibiae and metatarsi ; 
hind metatarsi about the same length as the hind tibiae ;. ungues 
very small, equal and simple. 
Wings with typical Culex scales; scales brown; fork-cells 
rather short; the first sub-marginal cell longer and slightly 
narrower than the second posterior cell, its base just a little 
nearer the base of the wing than that of the second posterior 
cell or level with it ;. its: stem about half the length of the ‘cell;
