Doings of Societies. 
At the meeting of the Feldman Collecting Social, held on 
November 20th, 1907, at the residence of Mr. H. W. Wenzel, 
1523 S. Thirteenth Street, Philadelphia, there were ten mem- 
bers present, and Mr. John A. Grossbeck, visitor. 
Professor Smith spoke about Culex perturbans and its 
habits. This is a species which for three or four years last 
past has been hunted by all those interested in mosquito work; 
but not until this year were the habits of the larva ascertained. 
The first stages of the larva had become known from eggs 
obtained from gravid females; but what became of them after 
they got out of the eggs nobody knew. 
Briefly stated, the eggs are laid in a raft on the surface of 
the water in densely overgrown swamps, illustrations of which 
were shown. The young larve hatching from these eggs at 
once make their way through the water to the mud surface 
and through the mud surface among the root mass below. 
Among these roots, anywhere from 2 to 4 inches below the 
bottom, the larve attach themselves by their anal tube and 
remain concealed from all ordinary natural enemies and in 
territory where no other mosquito larve can breed. The air 
supply seems to be obtained chiefly through the vascular system 
of the plants which is very loose and open. 
Mr. Grossbeck, in supplement, explained how he had found 
the breeding places by hunting egg boats, of which he finally 
found large numbers, at Lahaway, in Ocean County, and at 
Trenton, in Mercer County. He further described the par- 
ticular character of the plants among which the larvze are found 
and told how he collected them by forcing the net below the 
grass tussocks and, by disturbing the larve attached to the 
roots, got them into the free water, where he could get them 
with the net. 
Mr. Kaeber exhibited several species of ‘Coleoptera and 
Lepidoptera, which he collected in Arizona in the past sum- 
mer, which showed remarkable mimicry, and stated that the 
beetles and moths were taken at the same places and time, and 
in some cases were beaten from the same trees.
