LIFE-KISTORY OF AEDES SMITHII COQ. 

 Bv John B. Siniith, Sc.D. 



As Dr. Harrison G. Dyar has described and figured the larva of 

 this species in the last nimiber of this Journal (Vol. IX, p. 178), 1 

 will not again rehearse the characters given by him. 



My first acquaintance with the insect began in late November, 

 1900, when Mr. J. Turner Brakeley called my attention to the fact 

 that, in the pitcher plants in the swamps surrounding his cranberry 

 bogs at Lahaway, there were what he thought mos([uito larvse. The 

 matter did not interest me very strongly at the time. I verified the 

 fact that they were mos(iuito larvae and, because that s]jecies was com- 

 mon about there, I assumed that it was piiiigens. Dr. Howard's 

 pamphlet on mos(iuitoes had been not long since published, and the 

 larvge in the leaves of the plant fitted to his pictures and description 

 sufficiently well. As Ciilex puiigcns breeds everywhere, it did not 

 strike me as especially odd that the larva should be in the leaf pitchers, 

 and I assumed that they were, probably, present in the bog holes and 

 ditches as well. 



In reply to the question, what will Ijecome of these larvcTe, I in- 

 formed Mr. Brakeley that Culex /^i/ngcns hibernated as an adult ; that 

 the larvae are dependent upon atmospheric air and that these specimens
