Doings of Societies. 



At the meeting of the Feldman Collecting Social, held on 

 November 2Oth, 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 Cule.v pcrturbans 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 larvae 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 larvae attach themselves by their anal tube and 

 remain concealed from all ordinary natural enemies and in 

 territory where no other mosquito larvae 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 larvae are found 

 and told how he collected them by forcing the net below the 

 grass tussocks and, by disturbing the larvae 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.
