NEW CULICINE LARVAE FROM THE GOLD COAST. 



11 



simple hairs. The siphon is long and narrow, eight or nine times the length of its basal 

 diameter, the pecten extending to a quarter of the length of the siphon, and beyond 

 it are four or five ventral tufts composed of simple hairs. There are 12-15 teeth in 

 the pecten. The anal segment is a little less than twice as long as it is broad, the 

 papillae being sharply pointed, and slightly shorter than the segment. Two of the 

 hairs on the dorsal end of this segment appear to be longer than the siphon. 



This larva apparently comes near those of C. invidiosus and C. decens in Edwards' 

 key (Bidl. Ent. Res. iii, pp. 380-381) " Comb of eighth segment with about 40 teeth 

 in a triangidar patch. . . . Pecten with 12-15 teeth, antennal tuft at about three- 

 quarters ; siphon 8 X 1." It may be distinguished by its dark antennae and by the 

 dark hairs on the anal segment. In life its colour should help in the difEerentiation, 

 as the larvae of C. invidiosus and C. decens are usually green in colour. 



Pu/pa. — The pupa seemingly has no distinguishing characteristic. 



Breeding place.- — The larvae were found in holes excavated by the native children 

 in search of crabs ; the water contained in the holes held much matter in suspension.
