In tlie pot-hole area, tlioiigli many of the holes held water, no 

 breeding was in progress, but adults were present in great num- 

 bers. Camimis or abfitcMi were most abundant in the ratio of ten 

 to one cantatov, and all were vicious in the attack. A few sylves- 

 tris were also seen, but these were timid and more frequently 

 alighted on the clothing than on exposed poa*tions of the body. In 

 all eases they were very slow in l)iting, in marked contrast to the 

 canians. 



June 25th, ]\[r. lirehme again collected over this area finding 

 no more breeding, and nine worn C. caniaior, five fresh C sollici- 

 tcms from the third Elizabeth brood and one worn C. cantans. 



On the same day, out of fifteen examples caught in Mr. Ren- 

 Avick's garden, fourteen were cantans or abfifcJu'i and one was can- 

 tator. 



June 26th, Mr. Brehme and Mr. Grossbeck made another col- 

 lection and examination of the pot holes. For over a week there 

 had been frequent rains and enough time had elapsed since the 

 first to bring out any mosquito larvse that may have been ready 

 to develop. But though many pools were found with water, abso- 

 lutely no larva} were present. Adults were still numerous and 

 fierce and all save 3 to 4 per cent, of cantator were ahfitchii or 

 canians. The latter were much worn, however, and survivors of 

 the early May brood. "It was interesting to see how this species 

 keeps to the woods. Ten feet from the woods not a specimen was 

 to be seen, but upon entering a few feet into it one would be: at once 

 surrounded by a humming swarm. They alight without hesita- 

 tion and bite directly. About 100 specimens were taken in less 

 than ten minutes." 



What Mr. Grossbeck says above shows that it is quite possible 

 for two persons to collect over the same area and make quite a dif- 

 ferent showing at the end of the day. The one keeping in the open 

 would get C. cantator almost exclusively, the one keeping to the 

 woods would ha-\-e a strong predominance of C. cantans. 



June oOth, amtthcr trip by Mr. Brehme showed neither larvte 

 nor adults at Springfield. At Millburn no larva^ were found, but 

 there wore plenty of C. cantaior and a very few C. cantans. In the 

 woods tlio number of mosquitoes was materially reduced and larva? 

 Avere yet absent. On the South mountain there was no In-eeding, 

 iir.d of twentv-seven adults, twentv-one were ('. cantator, very much
