Notes on Some Mosquito Larvae Found in 



New Jersey. 

 BY JOHN B. SMITH 



(With Plates IX, X, XI, XII.) 



Culex trivittatus Coq. 



This is a grayish-black mosquito, with two white longitudi- 

 nal stripes on the dorsum of the thorax. The legs and the 

 beak are not banded, while the segments of the abdomen are 

 white marked laterally and often across the dorsum. 



Larvse were first taken by the Messrs. H. H. and E. Brehme, 

 who were exploring the woodland pools on the hills back of 

 South Orange. Each turned in a bottle of larvae and pupae 

 that were determined to be a mixture of Conchyliastus miisiciis 

 and Culex sylvestris. From the E. Brehme bottle, C. musicns 

 and C. sylvestris adults emerged July 2d, and in addition sev- 

 eral examples of what was recognized as a species new to us. 

 The remaining larvae were closely examined, but could not be 

 differentiated from sylvestris. Meanwhile a large number of 

 pupae had developed and from these and from the collected 

 stock C. trivittalus , C. sylvcslris, C. canadensis, C. tcrritans and 

 C. musicus emerged. No larvae of trrritUtti<x were obtained 

 from this series.
