Gnlex trivittatns 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. 



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

 who were exploring the w'oodland 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 musicus 

 and Cidex sylvestris. From the E. Brehme bottle, C. musicus 

 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 larv£e 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. sylvestris, C. canadensis, C. territans and 

 C. musicus emerged. No larvae of trivittatus were obtained 

 from this series.
