The larva is described by Dr Dyar in the Journal of the New 
York Entomological Society for 1902, page 197. This larva 
differs from that of A.smithii in having four long narrowly taper- 
pointed blood gills instead of but two. The antenna has a tuft 
of hair a little before the middle; the breathing tube is about 
three times as long as wide; its spines are single toothed. The 
ninth segment has tufts before the barred area; the lateral 
combs of the eighth segment consist of a single irregular row of 
rather course spines. 
“The pupa is normal, its air tube cylindrical, slightly bent 
but not widened into funnel shape.” 
Aedes smithii Coquillett 
Plate 47, fig. 1-6 
The adult is described by Coquillett in the Canadian Ento- 
mologist, 1901. Of the life history Prof. J. B. Smith has discoy- 
ered the following:! 
“The female Aedes lay their eggs in the newest leaves of 
the pitcher plants (Sarracenia), and do not always wait for 
| water to collect in them. Of the specimens of larvae which he 
had taken during the winter the last one changed to the pupal 
| state about Sep. 9; thus being in a larval state since the preced- 
| ing October. He thought that there were about three broods, 
| and that the different specimens vary in their time of appearing, 
which seems to give one continuous season.” 
The larva has already been well described by Dr Dyar, in 
| New York Entomological Society Journal, December 1901, page 
| 178, plate 10, figure 1. It greatly resembles the larva of 
| Culex, this species differing from the known members of that
