Genus Culex . 
159 
Fou Chow, Bengal, &c., black and white ; and some sent from 
Gibraltar, Hong Kong, &c., have now black and now pale 
scales. 
Ungues, genitalia and palpi I find constant. But in 
regard to coloration and thoracic ornamentation there is some 
marked variation, and I have been able to separate several sub¬ 
species in this respect, for which I propose the following names, 
retaining those previously given for species now sunk under 
sub-species of C. fatigans :— 
A. Type. —Abdomen dusky black, with basal pure-white 
bands and basal white lateral spots; pleurae 
and metanotum chestnut-brown; thorax with 
two dark parallel lines. 
•• 
B. Sub-species luteoannulatus. n. s. sp. 
Abdomen dusky black or brown, with basal flaxen 
curved bands and pure-white lateral spots; 
pleurae and metanotum chestnut-brown ; thorax 
with traces of two parallel bare median lines. 
C. Sub-species Macleayi. Skuse. 
Abdomen brown, with basal pale flaxen to almost 
white bands and white lateral spots ; thorax 
with two very clear median parallel bare lines 
in front, widening out towards the fore end. 
D. Sub-species Skusii. Giles. 
Abdomen with pale flaxen bands and white spots ; 
the thorax with traces of four parallel bare 
lines. 
E. Sub-species trilineatus. n. s. sp. 
In which the median line of dark thoracic bristles 
shows as a third median line on the thorax. 
Each of these sub-species can again be divided into varieties 
according to the colour of the spots on the first abdominal segment 
as follows :—• 
variety 1—with scales pale yellow. 
„ 2—with scales dusky black. 
„ 3—with scales pale yellow and black.
