CHAPTER IV 



Culicidae (continued) : The Anopheles Mosquitoes 



The Anopheles mosquitoes can be distinguished by the 

 simple curve of the free edge of the scutellum and the straight 

 proboscis ; in the female the maxillary palps are equal to the 

 proboscis in length. 



We shall treat them here as forming a section of the 

 CulicincB, as follows : — 



Subfamily CULICIN^. 



Section I. — Epialurgi ( = Anophelin(B of Theobald) ; 

 (Gr. ^irlaXos = ague fever ; epyov = work). 



This section includes the single genus Anopheles, with 

 probably about lOO known species distributed in all the 

 great zoogeographical regions, but most abundant in the 

 tropics. 



Theobald, using characters exhibited by the scales, has segregated the 

 species oi Anopheles in more than twenty "genera" ; but as this course 

 seems to me to override natural affinities I have not followed it in all 

 its ramifications. It must be admitted, however, that the form and the 

 arrangement of the scales, when considered along with other characters, 

 do give help in splitting the genus into groups ; but as all these groups 

 can be linked together by annectant forms, it seems to me to be much 

 more natural (as well as more suited to the convenience of the medical 

 officer) to regard them as a series of intergraduating subgenera. 



The subgenera here recognised are Anopheles (sensu restricto), 

 Myzorhynchus, Arribalzagia, Christya, Myzotnyia, Nyssorhynchus, and 

 Chagasia. Under Nyssorhynchus, again, three series may for convenience 

 be admitted, namely, Nyssorhynchus (restricted), Ncocellia, and Celliaj 

 and under Myzomyia two series are suggested, namely, Afvzovtyia 

 (restricted) and Pyretophorus.
