and especially between the larvae, is so great ; but on the other 

 hand there are other genera among the true Culicidae, such as 

 Culex and Anopheles, of which the imagines, at any rate in one 

 sex ' are so like as to lead to confusion while the larvae are 

 exceedingly different. * * * " 



Abnormal characters. — Genera founded on legitimate varia- 

 tion of bodily structure are very few, Dactylomyia, Lophocera- 

 tomyia, Rachionotomyia , Deinocerites, Dinomimetes and Runcho- 

 myia, all dealt with further on, are, apparently, all that can be 

 found in Culicidae.

SUBFAMILIES AND SECTIONS IN CULICIDAE. 



Having compared the principal characters in Culicidae with 

 the same characters in other families of diptera we can proceed to 

 examine the genera proposed of late years and estimate their 

 validity. 



The Culicidae form only two subfamilies* Culicinae and 

 Coreihrinae and the former should be divided into four sections 

 only.^ 



Table of sections in Culicinae. 



Scutellum simple, never trilobed ; palpi long 

 in cf and 9 ; larva without respiratory 

 siphon .. .. .. / Anophelini. 



Scutellum trilobed; palpi variable, generally 

 shorter in 2 than cf ; larva with res- 

 piratory siphon. 



Metanotum nude. 



Proboscis strongly recurved . . // Megarhini. 

 Proboscis normally straight ; 

 never recurved as in the Me- 

 garhini . . . . Ill Culicini. 



Metanotum with scales, chaetae or 



both .. .. ..IV Sabethini. 



Section I. ANOPHELINI. 



The genus Anopheles in the original sense is a very well 

 defined and natural one, characterized by the non-trilobed scutel- 

 lum in conjunction with the long palpi in both sexes. A secondary 

 character is the larva being without a respiratory siphon, whilst 

 the generally maculated nature of the wings in the adult, formed 



1 Meinert adds in a footnote " Thus with regard to Culex nemorosus see Zett. 

 (Dipt. Scand. 3458, note) : — '■ caveas ne hunc cum Anophele bifasciato confundas." 



2 Mr. Edwards desires to add the Dixinae as a third subfamily, but though 

 this view has the support of as sound an authority as Prof Wilhston, I think Dixa 

 is best separated from the family. 



? Mr Edwards uses practically the same names, though I had personally 

 decided on them months before his paper was seen by me
