OTHER GENERA OF MOSQUITOES 155 



Stegomyia, Toxorliyncliites, Uranoteiiia and 

 Ooncliyliastes. 



As will be iDoiuted out and fully explained in Chapter 

 X., these four generic names are here used for certain 

 American mosquitoes for the first time. I am able to use 

 them in this book through the great courtesy of Mr. F. V. 

 Theobald, of Wye, England, who has sent me proof sheets 

 of his monograph of the mosquitoes of the world, now 

 being published by the British Museum. Stegomyia 

 includes, as has already been shown, the yellow-fever 

 mosquito, S. fasciata, and it also includes the species 

 mentioned in my previous writings as Culex signifer Co- 

 quillett, and which has been captured in the District of 

 Columbia and Virginia by Messrs. Coquillett, Barber, and 

 Pratt. Toxorhynchites includes the species previously 

 referred to as MegarJduus rutllus and which must now be 

 known as Toxorhynchites rutilus. Uranot?enia includes the 

 North American species previously known as Aedes sap- 

 pirhinus. Conchyliastes includes two species formerly 

 placed in the genus Culex and which must now be known 

 as Conchyliastes imisicns Say and Conchylicistes post i rat if s 

 Wied. The former species has l)een taken in Pennsylva- 

 nia, Virginia, District of Colund)ia, and Texas by Messrs. 

 Johnson, Pratt, Thayer, and Barl^er.
