Stegomyia vittata, Bigot. 



Culex vittatus, Bigot, Ann. 8oc. Ent. France, (4) i, p. 227 (1861). 



Slegomijia sugens, Theobald, Mon. Cul. i. p. 300 (1901), et auct. {nee Wied.). 



Steyotmjia bnimpli, Neveu-Lemaire, lUiU. Soc. Zool., France, xxx, p. 8 (1905). 



Reedomyia albopundala, Theobald, Mon. Cul. iv, p. 262 (1907). 



There is unfortunately little or no doubt that Theobald wrongly identified Wiede- 

 mann's C. suge)ts, since that author does not mention the white rings on the femora 

 and tibiae, which he certainly would have done if they had been present. It is 

 impossible to say from the description what Wiedemann's C. sugens really was, but 

 if the type covdd be found it might perhaps prove to be a rubbed S.fasciata. 



Stegomyia fraseri, Edw. (fig. 5 c). 



This species was described by me (Bull. Ent. Res. iii, p. 11, May 1912) from a 

 single female from Uganda. Since then a good series including both sexes has been 

 received bv the Imperial Bureau of Entomology from Southern Nigeria ; unfor- 

 tunately the names of the locality and collector have been lost. These specimens 

 agree perfectly with the t\'pe female. The male genitalia (shown in fig. 5c) resemble 

 those of S. apicoargentea, except in having two instead of four bristles at the tips of 

 the harpagones. A single female has also been taken by Mr. A. Bacot at Freetown, 

 Sierra Leone. 



Stegomyia tliomsoni, Theo. (fig. 5 d). 



A series of specimens bred from larvae taken in a hollow tree have been received 

 from Pusa, Bengal {F. M. Howleft). The palpi are alike in both sexes, though rather 

 longer and more distinctly jointed than in Aedes. In view of the type of ornamenta- 

 tion of this species and also of the structure of the male genitalia (fig. 5 d), it seems 

 best placed in Stegoniijia. in spite of the short male palpi.

I have also seen a male of S. annidirostris, Theo., taken by Major S. P. James in 

 Ceylon; this species, which is evidently nearly allied to S. thomsoni, also has the 

 palpi alike in the two sexes.
