Genus COELODIAZESIS, new.

 ment, and the absence of short teeth on the comb of the eighth 

 segment. Type, C. barberi Coq.

Anopheles barberi Coquillett, Can. ent., xxxv, 310, 1903. 

 Anopheles barberi Dyar, Journ. N. Y. ent. soc, xii., 243, 1904. 



The larvae live in the water in hollow trees. This habit is unique 

 among the Anophelinae, which are in general surface feeders in open 

 water. As a compensation for the restricted surface offered in their 

 habitat, the larvae have acquired a predaceous habit and devour the 

 unfortunate larvae of Aides triseriatus and Mansonia signifer with 

 which they live.
