G Antennae in & fancifully orna- 

 mented .. .. Lophoceratomyia, Theoh. 

 GG Antennae in both sexes without 

 such fanciful ornamentation.

3 — 4-jointed . . Culex, Iv. 



HHH Palpi in cf and $ a-jointed . . Ludlowia, Theob. 

 BB Scutellum produced into a 



blunt spine ( 0^ unknown) . . Rachionotoniyia , Theob. 

 AA The 2nd antennal joint many- 

 times longer than usual . . Deinocerites , Theob. 



N.B. — The above table is offered with some diffidence since 

 several of the more striking genera are unknown to me and the 

 remainder rest on the trustworthiness of the characters set up 

 by their promoters. 



Generic notes on the Culex group. 



Psorophora, R. Desv. 



Janthinosoma, Arrib. 



Mucidus, Theob. 



These three genera are sufficiently clearly characterized, provid- 

 ing alwa3^s that the position of the posterior cross vein beyond the 

 anterior cross vein holds constant in all the species. This is by 

 no means certain in M. alternans, Westw. and M. sudanensis, 

 Theob., for instance. 



As regards the palpi, Theobald says Psorophora has them 4- 

 jointed, admitting that Robineau Desvoidy and Arribalzaga 

 claimed 5 joints for them, but in Mucidus although he describes 

 six species in his monograph he does not mention any number 

 in the $ palpi.' In his " genera of the Mucidus type," Col. Alcock 

 includes M ansonia , Mansonioides, " Etorilepidomyia" {?=Eiorlep- 

 tiomyia), Orthopodomyia, Aedimyia and F inlay a. 



Ekrinomyia, Leices. This genus is apparently sound, the 

 po.sterior cross vein being bej^ond the anterior one, but the 

 prominent outstanding scales on the legs being absent prevent it 

 being confused with the first three genera. 



Stegomyia, Theob. 



Quasistegomyia, Theob. 



Kingia, Theob. 



Blanchardiomyia, Brun. {Desvoidy a, Blanch.). 



Scutomyia, Theob. 



1 The continual recurrence of omissions like this render it almost impossible 

 for a systematist to arrive at just conclusions.
