228 F. W. EDWARDS — NEW SYNONYMY 



17. Ochlerotatus imprimens (Walk.). 



Culex imprimens, Walk., Proc. Linn. Soc. v, p. 144 (1861). 



(?) Culex auratus, Leic, Cul. of Malaya, p. 153 (1908). 



Culicada suknaensis, Theo., Rec. Ind. Mus. iv, p. 21 (1910). 

 Walker's type, though damaged, is not by any means past recognition. 

 Leicester's C. auratus is probably the same species, but as I have seen no 

 specimen I only include it here provisionally. In any case Leicester's name is 

 preoccupied by Aedcs {Ochlerotatus) auratus, Grabham (1906). 



18. Ochlerotatus stenoetrus (Theo.). 



Culex stenoetrus, Theo., Mon. Cul. iv, p. 395 (1907). 



Culicada minuta, Theo., Mon. Cul. iv, p. 338 (1907). 



Culicada ei*uthrosops, Theo., Mon. Cul. v, p. 299 (1910). 



Culex pseudostenoetrus, Theo., Mon. Cul. v, p. 343 (1910). 

 There are some very slight differences between the above-mentioned forms, 

 notably in the colour of the thoracic scaling, but nothing sufficient to distinguish 

 them specifically. C. pseudostenoetrus is said by Theobald to differ from 

 C. stenoetrus in having no pale apex to the palpi, and in the venation, but this is 

 not true ; even the type of C. pseudostenoetrus has a pale apex to the palpi, and 

 the venation is quite similar to that of C. stenoetrus. C. minuta has a somewhat 

 distinct appearance and a noticeably paler thorax, but can, I think, be included 

 here with safety ; otherwise it will require renaming, as the African O. minutvs 

 (Theo.) was described earlier. 



19. Ochlerotatus pulchriventer (Giles). 



Culex pulchriventer, Giles, J. Bomb. Nat. Hist. Soc. xiii, p. 608 (1901). 

 Howardina himalayana, Giles, J. Trop. Med. vii, p. 384 (1904). 

 Both types are in the British Museum, and are evidently conspecific. 



20. Ochlerotatus pallidostriatus (Theo.). 



Culex pallidostriatus, Theo., Mon. Cul. iv, p. 410 (1907). 



Culex par ascelos, Theo., Rec. Ind. Mus. iv, p. 18 (1910). 



Ochlerotatus ochraceus, Edw. (part), Bull. Ent. Res. ii, p. 250 (1911). 

 This species can be distinguished by the male genital characters from 

 O. ochraceus, which appears to be confined to the Ethiopian region, as this is to 

 the Oriental. 



21. Ochlerotatus mediolineatus (Theo.). 



Culex mediolineatus, Theo., Mon. Cul. ii, p. 113 (1901). 

 Culex trilineatus, Theo., Mon, Cul. ii, p. 105 (1901). 

 Types compared, leaving no room for doubt as to the synonymy. 



22. Ochlerotatus ostentatio (Leic). 



Aioretomyia ostentatio, Leic, Cul. of Malaya, p. 193 (1908). 

 Pseudoliowardina chrysoscuta, Theo., Mon. Cul. v, p. 228 (1910). 

 The male of this species being unknown, its location in Ochlerotatus rather than 

 in Andes is purely a matter of conjecture.
