232 F. W. EDWARDS — NEW SYNONYMY 



the subsequent use of the name for any other species of true Culex. This is a 

 very striking species, and I have no doubt whatever concerning the synonymy. 

 I have examined the Indian Museum type of T. lutcoabdominalis, and find that 

 Theobald's description is not quite correct. The legs of the type are somewhat 

 rubbed, but do show traces of pale rings on the tarsi, such as are conspicuous in 

 perfect specimens. The species is a true Culex* and is evidently related to 

 C. sinensis and C. bitaeniorhynchus.

Culex albus, Leic, Cul. of Malaya, p. 148 (1908). 

 The types of T. whitmorei and L. plegepennis are in good condition in the 

 British Museum, which possesses a fairly good series of the species. Miss Ludlow 

 has kindly presented some named specimens of T. aryenteus to the Museum. 

 Although I have not seen the type of C. albus, the species is so very 

 distinct from all others that I have not the least hesitation in quoting the 

 synonymy as above.

 I have devoted considerable study to the small banded-proboscis species of 

 Culex, and have come to the conclusion, after examining large series, that there 

 are only three common Oriental species of this group, apart from such well- 

 marked forms as those already referred to in this paper. Of these three 

 species, C. sitiens may be recognised as follows : it is much blacker than the 

 other two, and also somewmat larger ; the scaling of the mesonotum is dark, but 

 not uniform ; the femora and tibiae have light and dark scales more or less 

 intermixed ; the first fork-cell in both sexes has its base slightly nearer the 

 apex of the wing than that of the second ; the long joint of the male palpi 

 has a regular row of stiff translucent hairs projecting downwards and inwards. 

 I have adopted the name C. sitiens for this species because Wiedemann's de- 

 scription fits it better than any other, while it certainly does not apply to the 

 species which Theobald interprets as C. sitiens ; Wiedemann gives the general 

 colour as black, which would only apply to this species ; moreover the size he 

 gives would apply better to this than to either of the two following. Walker's 

 type is of course in very bad condition and hardly recognisable, but I have 

 included his C. impellens here because, contrary to Theobald's implication, the
