360 THE CANADIAN ENTOMOLOGIST. 



also brownish ; claws all uniserrated ; wings hyaline with slender 

 brown scales and broad whitish ones, petiole of first sub-marginal cell 

 about half the length of this cell. Length 4.5-5 mm. 



Types, 2 females in the New Jersey Experiment Station collection. 

 This species is at once recognizable by its silvery lustre and cream- 

 coloured legs. 



A single specimen of this species hatched May 5ih out of a lot of 

 larvae and pupas sent in by Mr. Brehme, who collected them as Culex 

 Canadensis from the Orange Mountains. The remaining larvae were 

 immediately put into alcohol and the pupse left to develop; but all 

 Canadensis emerged from the pupse and no larvae distinguishable from 

 that species could be found. Another collection in the same locality was 

 made several days after the first and from this lot another female hatched 

 May 26th. Of the numerous other larvae with which they were associated 

 all were Canadensis and one Corethra cinctipes. Wc had evidently 

 gotten hold of the tail end of the brood ; no larvse remaining. 



Ctdex saxatilis, sp. nov. $ • — Head brown, occiput covered with 

 yellowish white scales and some dark brown ones ; antennae and proboscis 

 dark brown, the former with scattered whitish scales; palpi brown, 

 apparently three jointed, the fourth being minute, pointed and wholly re- 

 tracted within the third joint. Mesonotum' clothed with rich brown scales 

 and pale yellowish ones at the margins ; two naked lines extend down the 

 anterior part and two pale yellowish spots are on the centre of the dorsum 

 which become more or less diffused posteriorly : scutellum brown with 

 yellowish scales and long black bristles on the posterior margin ; metano- 

 tum grayish brown ; pleura light brown with small patches of dirty white 

 scales ; halteres yellowish. Abdomen dark brown, all segments with 

 apical white bands which become broad laterally, till, beneath, it is white 

 with dark brown basal corners. Legs black, coxae, base and under side 

 of femora and a small spot at the knee creamy ; claws simple ; wings 

 hyaline, the scales brown, petiole of first sub-marginal cell about one-third 

 the length of this cell. Length 4.7-5 mm. 



Types, six females in the New Jersey Experiment Station collection. 

 Distinguished from Culex territans, its nearest American ally, by its large 

 size, dark colour, broadly banded abdomen and spotted thorax. 



Pupae of Culex saxaiilis were found August 31st on Garret Mountain 

 (Paterson), in a rock-bottomed pool, associated with larvte and pupae of 

 C. pipiens. In the afternoon of the same day two females emerged to- 

 gether with %tv&x?i\ pipiens. Sept. ist, 5 others, all females, hatched with 

 moxQ pipiens. Later emergences were all pipiens. As in the preceding 

 species the last of the brood was collected in the pupal stage ; no larvae 

 remaining.
