Skusea simplex, Theo.

Aedes simplex, Edw., Bull. Ent. Res. iv, p. 238 (1913). 



The simple claws of the female and the long processes of the male genitalia would 

 seem to justify the association of this species with pemhaensis, although the claspers 

 are much reduced, and, as in Aedes, have no distinct spine. I have shown the structure 

 of the genitalia as well as I could make it out in the single specimen (fig. 9 b and c). 



Skusea longirostris, Leic. (fig. 9 d). 



Ficalbia lonyiroslris, Leic, Cul. of Malaya, p. 228 (1908). 



Although not at all closely related to the species mentioned above, this species would 

 seem to be better placed here than in Aedes, owing to the simple female claws. As in 

 most species of Aedes, the male genital clasper seems to be without any trace of an 

 articulated spine. 



Genus Taeniorhynchus, Arr. 



Taeniorhynchus nigrosignatus, nom. nov. 



Taeniorhynchus conopas, Theo., Mon. Cul. i, p. 202 (1901) (nee Culex conopas, 

 Frauenf.). 



? Pseudotaeniorhynchus conopas var. giblini, Taylor, Trans. Ent. Soc, 1914, p. 198. 



It is quite obvious from Frauenfeld's description of C. conopas that the insect he 

 had was not one of the yellow species of Taeniorhynchus with black-ringed legs ; 

 what it was is impossible to say without seeing the type, since the description is quite 

 inadequate, but it may possibly have been Mansonioides imiformis. 



So far as can be judged from Taylor's description of T. giblini, this form shows 

 sufficient differences to be distinguished specifically from Oriental specimens, and as 

 there is no other name available for these latter the above new designation is proposed. 



Genus Culex, L. 

 Since the different groups of Aedes are now regarded as only subgenera, it is desirable 

 that the name Culex should also be employed in a rather wider sense than that in 

 which I have used it. The structural differences between Culex, Culiciomyia, 

 Lophocer atomy ia and Micraedes are of much less moment than those between the 

 various groups of Aedes, and it is doubtful whether some of the former names should 

 be retained even in a subgeneric sense. Culiciomyia and Lophoceratomyia are fairly 

 distinct, and so are the large carnivorous forms Lutzia and Jamesia, but Cyathomyia 

 might well be regarded as merely somewhat aberrant species of Culex. An undes- 

 cribed species from Japan affords a good connecting link between Cy. brevipalpis, 

 Giles, and typical Culex, and among the American species there are apparently some 

 with male palpi intermediate in length between those of Cy. brevipalpis and Micraedes 

 inconspicuosus. 



Subgenus Culex, L. 



Culex tritaeniorhynchus, Giles. 



This species has so far only been recorded from the Oriental and Eastern Palaearctic 

 regions, but by a strange coincidence T recently received for examination on the same 

 day a male from Zanzibar {Dr. W. M. Aders) and a number of females from Accra,
