REPORT OX MOSQUITOES. 341 



New York Entomological Society, which agrees in substance 

 with my observations and which it will be convenient to quote: 

 "The eggs fonn a boat-shaped mass floating on the surface of 

 the water, much as in Cidex pungcns^ but the mass is smaller, 

 containing a less number of eggs and is less regularly elliptical, 

 more angular. It floats less on the surface, the middle eggs be- 

 ing nearly half submerged. The sculpture and color of the in- 

 dividual eggs are also different. The newly— hatched larva at 

 •once takes up the usual feeding position. This is essentially as 

 in Cnlex, but the body is held more flatly, more parallel to the 

 surface, yet below the surface film. Consequently, though feed- 

 ing as Cidex, the larvae resemble Anopheles at a casual glance 

 and were several times at first mistaken for them. The larvse 

 are fond of resting below the leaves of the Levmia, where they 

 remain with the air tube penetrating the surface and feed, often 

 Avith a rotary motion of the body on the air tube as an axis. 

 Occasionally they bend up to feed at the surface. They are not 

 timid and often a considerable commotion of the water is neces- 

 sai-y to send them to the bottom. The head may be partly ro- 

 tated on the neck, but the habit is not so completely developed 

 nor so frequent as in AnopJieles, which regularly feeds with the 

 head inverted. It has an elongate, dark brown head with a con- 

 trasting pale body, the hairs of the anterior abdominal seg- 

 ments markedly longer than those of the succeeding ones. Of 

 the local species (at Bellport), it most suggests the species of 

 Anopheles, as above noted. The long anterior hairs assist in 

 the deceptive appearance. There seem to be four larval stages, 

 the last three being essentially alike, except for the successively 

 larger size. This is shown best by the head as in Lepidopterous 

 larvae. The head gradually becomes paler, being black in the 

 young larva and brown in the large ones. The pupa resembles 

 that of Cnlex, but is very small and has unusually long air tubes. 

 The species seem tO' breed continuously all summer, preferring 

 warm, stagnant pools of some size, containing Spirogyra." 



At Lahaway I found the egg boats near the shallow edge of a 

 large fish pond and the larvse among the vegetation along the 

 shallow edge of a lily pond in late June. Mr. Grossbeck found 

 larv^se in Cadwalader Park, Trenton, August 5th ; Mr. Brehme 

 found it at Metedeconk, September 23d, and at Irvington, Sep- 

 tember 15th. Mr. Brakeley has found single specimens at dif- 

 ferent periods during the summer. It is what he calls a local 

 breeder, being found in about the same places each year and 

 always in permanent bodies of water.
