The larvae in life are of a light green colour. 



The head is large, being nearly as wide as the thorax. The antennae have the distal 

 third darkened and are covered with spicules, the tufts being placed at two-thirds of 

 the length of the antennae and formed of plumose hairs. The brushes are large, and 

 the mid-frontal hairs are double and plumose. The comb consists of about 50 scales 

 arranged in a triangular patch. The hairs of the subsiphonal and siphonal plumes are 

 plumose, the hairs of the anal plume simple. The siphon is long and narrow, 

 14 times the length of its diameter at the base and about three-quarters of the 

 length of the abdomen. The pecten is formed of about 12 paired and barbed spines, 

 the last two being more widely separated ; beyond these true pecten spines, which 

 extend to about one-third of the length of the siphon, are three or four widely 

 separated spines on the mid-ventral line, and in addition to these there is a group of 

 five or six simple spines lying just below the apex and more closely appressed to the 

 siphon. There are minute hair-tufts of simple hairs inserted between the more widely 

 separated distal spines. The pointed anal papillae are not quite twice as long as the 

 anal segment. 



This larva may be distinguished from the other Culex larvae in Edwards' key 

 (Bull. Ent. Res. iii, pp. 380-381) which have the " Combs of the eighth segment with 

 about 40 teeth in a triangular patch " by the formation of the pecten and by the length 

 of the siphon, 14 X 1. 



Pupa. — The pupa does not appear to have distinctive features. 



Breeding place. — ^The larvae were found in deep pools of clear water in the thick 

 forest. 



Culex consimilis, Newst. 



The larva in life is of a brilliant green colour. 



The head is large and the abdomen well developed. The hair-tuft is formed of 

 simple hairs and is inserted at or just before the middle of the antenna. The thorax 

 and abdomen have the usual plumes. The comb is formed of six teeth arranged in an 

 irregular line, there being a simple hair at either end of this line of spines. The hairs 

 of the subsiphonal plume are plumose, those of the siphonal pubescent. The length 

 of the siphon is ten times the diameter of its base and is less than half the length of 

 the abdomen (147 units to 356, average of six measurements). The pecten consists 

 of six feebly developed spines, which increase in size distally, the last being detached 

 from the others. 



Apparently there is little if any difference between this larva and that of C. annulioris 

 in Edwards' Key (Bull. Ent. Res. iii, p, 381). 



Pupa. — The respiratory tubes have large apertures which are directed anteriorly, 

 the tubes being placed nearly parallel one with the other. 



Breeding place. — The larvae were found in masses of filmy algae in clear water. 



Eumelanomyia inconspicuosa, Theo. (hg. 10). 



The larva in life is very dark in colour. 



The head is dark and large being nearly as wide as the thorax. The antennae are 

 well developed, with a tuft of subplumose hairs situated at about the middle (described 

 from a single specimen). The midfrontal hairs are single and subplumose at their
