home those from the shack. They proved to be a pure culture 

 of C. varipalpus. 



The larva most nearly resembles that of C. atropalpus, being 

 furnished with long anal appendages and a short breathing tube, 

 while they wriggle slowly at the bottom of their dish, not coining 

 to the surface for a long time. They differ from C. atropalpus 

 in that the ventral brush of the last segment is a sessile tuft of 

 hairs like the dorsal one, without barred area. The general 

 habitus of the larva suggests Wyeomyia smithii. 



Culex territans Walker. 



The larvas were found in permanent pools by the edge of a 

 small lake, showing the normal appearance and habits. The 

 adults made no attempt to bite. Mr. Currie went down to the 

 edge of the lake and secured several by sweeping, but otherwise 

 all those secured were bred. 



Culex dyari Coquillett. 



This is a very early species and by no means common. On 

 May 29, immediately after my arrival at Kaslo, I found one 

 larva in a slow, cold stream in the woods. It pupated at once ; 

 so that even at that date the species had practically ceased breed 

 ing. No more larvae were found and no adults seen. 



Culex tarsalis Coquillett 



Two examples only occurred at Kaslo, one having entered my 

 room at the hotel, the other being taken at night while out sugaring 

 for moths. Larvae were found in a pool of permanent fresh 

 water near the sea at Victoria, B. C. They were mixed with 

 C. incidens. The larva belongs to the long-tubed group, with 

 the antennal tuft at the outer third of the joint, the antennas 

 broadly white banded, it falls in the synoptic table with C. 

 nigritulus,* but the air tube is not so long. The eggs were not 

 observed and may prove to be something unusual. 



Culex perturbans Walker. 



A single example was taken by Mr. Currie near the little lake. 

 The species was too rare for us to learn anything of its life 

 history. 



Culex curriei Coquillett. 



Likewise a single example, taken by Mrs. Dyar near Kaslo 

 Creek. This species also was too rare for us to obtain eggs or 

 learn anything of the larva. 



*Not the European nigritulus. Mr. Coquillett has proposed a new 

 name for the American species, culex salinarius, Ent. News, xv, p. 73, 

 1904.
