NOTES ON THE MOSQUITOS OF MADAGASCAR. 137 



basal arms of the tenth sternites. Perhaps the single specimen of C. annulioris 

 recorded by d'Emmerez de Charmoy (Ann. Trop. Med. ii, p. 260) may have been 

 G. giganteus. 



Culex (Culex) sitiens, Wied. 



Culex ronaldi, d'Emmerez de Charmoy, Ann. Trop. Med. ii, p. 259 (1908). 

 Recorded from Mauritius, but not from Madagascar, where however it is very 

 likely to occur, since it has a wide distribution from East Africa to Australia. 



Culex (Culex) univittatus, Theobald. 



Heptaphlebomyia montforti, VentriUon, Arch. Parasit. ix, p. 448 (1905). 



My previous statement as to the identity of C. univittatus and H. montforti is 

 confirmed by an examination of the male hypopygium of one of Ventrillon's 

 specimens. 



Culex (Culex) pgpiens, L. 



Tananarive (Neiret, 1904 ; Ve7itrilIon, 1905). 



This record forms a further notable extension of the known range of this species, 

 which until recently was thought to be confined to the temperate regions of the 

 northern hemisphere. It is now known also from South and East Africa and from 

 the Argentine. 



Culex (Culex) ? laurenti, Newstead. 



Some female specimens from Tananarive {Neiret, 1904) are perhaps this species, 

 though it is possible that they may belong to the variety of C. pipiens with an 

 unhanded abdomen, which is known from East Africa and from the Mediterranean 

 region. 



Culex (Culex) fatigans, Wied. 



Culex cartroni, Ventrillon, Bull. Mus. Paris, xi, p. 429 (1905). 



Culex anxifer, Bigot, Ann. Soc. Ent. France, (3) vii, p. 117 (1859). 



The hypopygium of Ventrillon's type male was mounted and proved it to be 

 this species. Other specimens from Eeunion {Surcouf). The commonest mosquito 

 in Mauritius {d'Emmerez de Charmoy). 



Bigot's description of C. anxifer is unrecognisable, and he had no type, but 

 Blanchard has referred his name to the synonymy of C. fatigans, and there seems 

 no sufficient reason to dispute this. 



Culex (Culex) argenteopunctatus, Ventrillon. 



Heptaphlebomyia argenteo punctata, Ventrillon, Arch. Parasit. ix, p. 446 (1905). 



Heptaphlebomyia kingi, Theobald, Ann. Trop. Med. vii, p. 601 (1913). 



A number of females, all in poor condition, some barely recognisable, from 

 Tananarive {Ventrillon, Bouet, Guerin Meneville, Waterlot). 



A male in the British Museum named by Ventrillon lacks the abdomen, but 

 fortunately there is another, in perfect condition, from the Gold Coast {Dr. A. 

 Ingram). I have mounted the hypopygium of this and find that it is a true Culex 

 bearing a rather considerable resemblance to C. decens, Theo. The two silvery spots 

 on the thorax are remarkable and absolutely diagnostic, being comparable only 

 with certain species of Aedes, e.g., punctothoracis, Theo.
