Breeding -places: — Larvae and pupae, allowed to develope in the 
laboratory, were taken from among the grass at the edges of rivers, 
from swamps, from the foul water of stagnant puddles, from collections 
of rain-water in old tins, and from the foul-smelling pools used for 
steeping manioc. 
This is evidently a variable species. None of the females agree 
with the typical form in the specific coloration of the head and thoracic 
scales. In the majority of the females, which agree best with 
Theobald’s* description, the narrow-curved head scales are creamy 
white in colour with, in some lights, a trace of pale yellow, 
especially in the frontal and large median ones; and the thoracic 
scales are smoky-brown with metallic reflections, almost golden in 
some lights, with the distribution of the yellow spots and lines as in 
the type. In addition to these variations, five of the females also 
possess a distinct median band to the proboscis and other distinctive 
characteristics. These forms are described below as a distinct variety 
Culcx tigripes, var. consimilis, n. var. (Newstead) 
FEMALE. — Head with the narrow-curved scales creamy-white, in 
some lights with a faint trace of yellow; upright forked scales black 
with smoky-grey tips; median hairs golden yellow. I horacic scales 
chiefly of a greyish colour, with dark brown ones intermixed 
Proboscis brownish-black with a broad and well-defined median band 
of pale ochreous scales; labella pale ochreous-brown. Palpi black 
or brownish-black with a patch of pale bright ochreous scales at the 
articulation of the first long segment ; apex with dusky white scales 
Abdomen dark brownish-black with scattered pale brown scales and 
narrow basal bands; basal segment with two median black apical 
spots ; sixth and seventh segments with two lateral apical pale spots 
Legs as in the typical forms. 
Length 67 mm. 
Localities: — Tshumbiri (July); Kasongo (Feb., April, May), 
Yambinga (Sept); M iamb we ; Leopoldville. The example from 
Leopoldville was bred from a larva procured in a grass swamp near 
the terminus of the railway. It is important to note that three female^ 
and four males of the more typical forms were bred from larvae 
obtained at the same time.
