CHAPTER V 



Culicidse (continued) : Culicales, Megalorrhini, and 

 Metanototricha 



The true Mosquitoes outside the genus Anopheles are here 

 treated in three sections as follows : — 



Subfamily CULICIN^,. 



Section II. — Culicales. 



Including Culicina, Heptaphlebomyince, Dinoceratina, ^dince, and 

 Uranotceniina of Theobald's Monograph. 



Mosquitoes of the Culex section, or Culicales, are dis- 

 tinguished from Epialurgi by having the posterior edge of the 

 scutellum trilobed, from Megalorrhini by not having the 

 proboscis bent like a pot-hook, and from Metanototricha by 

 not having scales or bristles on the metanotum. 



The scaly covering of the head shows much diversity, but 

 the scales on the side of the head at least are flat squames. 

 The scutum, scutellum, and abdomen are always thickly 

 covered with scales of some kind. 



The relative length of the palps is very variable ; all 

 gradations can be found, in both sexes, between palps which 

 are " long " and palps which are " short." For instance, in 

 Culex the palps are longer than the proboscis in the male and 

 about one-sixth the length of the proboscis in the female ; in 

 Leicesteria and Brevirhynchus they are longer than the 

 proboscis in the male, and from half to two-thirds that length 

 in the female ; in some species of Mucidus the female palps 

 are about three-quarters the length of the proboscis ; in 

 Orthopodomyia the palps in both sexes are about two-thirds
