specimen 1 therefore prefer to treat them as one species calling attention 
to the variations. This is a very large mosquito and resembles Culex 
Concolor in many points especially in having a large carnivorous larva 
which is often found in the same pools with the larva of C. Concolor but is 
quite distinct from it. It also resembles C. Halifaxii a species taken in 
“ The Dindings.” From this it differs in the marked spotting on the femora 
and tibiae and the position of the cross veins and the colour of the cephalic 
upright scales which in most specimens-are bright golden-brown and not 
creamy-grey. 
Culex Fatigans. 
Head deep brown, with pale golden crescentic scales centrally white 
scales along the orbital margins, on either side a patch of spatulate scales 
white near the orbital margin dark brown behind and numerous dark brown 
upright scales all over. Thorax brown with tawny scales. Abdomen 
dark°brown with well-marked creamy basal bands. Legs dark brown with 
creamy-yellow knee and ancle spots. 1 arsi unbanded. 
Female Head.—D ark brown, along the orbital margins is a narrow 
band of white crescentic scales broadening on either side into a small patch 
of spatulate scales behind which is a patch of dark brown spatulate scales 
the whole upper surface is covered with scattered golden crescentic an 
numerous dark brown upright scales. Basal joint of antennae ochraceous 
unsealed, second joint ochraceous at the base, remaining joints dark brown 
with dark brown verticils. Palpi and proboscis entirely covered with dar 
brown scales. 
Thorax .—Prothoracic lobes dark brown with silvery ciescentic scales. 
Mesonotum lHht yellowish-brown with two dark brown lines thinly covered 
with tawny or pale golden scales. Scutellum yellowish with a few pale 
scales. Number of bristles very variable. Pleurae translucent and tawny- 
yellow Wings with dark brown scales and long fork cells, first fork cell 
longer than the second its base a trifle nearer the wing base its stem about 
one-third the length of the cell; posterior cross vein about one-and-ha f 
times its own length distant from the median. Legs entirely clad with dark 
brown scales except on the under and lateral surfaces of the hind femora 
and at the apices of femora and tibiae where there are pale rings. 
Abdomen .—Dorsally clad with dark brown scales and white basal bands. 
The venter is entirely scaled with pale yellowish scales. 
Male .—Antennae with silky-brown plumes. Proboscis clad with deep 
brown scales. Palpi longer than the proboscis by the ultimate and half the 
penultimate joints clad with brown scales and shewing one narrow white 
band at the antepenultimate joint at the junction ot its basal and mice 
thirds. Last two joints with long hairs. Abdominal bands broader than 
those in the female those on the last segments having concave free edges. 
First fork cell in wing much narrower than the second; posterior cross \ ein 
about twice its own length from median. In all other respects the ma e 
resembles the female. 
Occurrence .-Found in houses all over the Malay Peninsula. The 
larvae bred in tins or pots in the neighbourhood of houses or in any little 
stagnant pool or drain but always in close proximity to houses.
