Culex ingrami, sp. n. (figs. 2, 3). 



Differs from C. invidiosus, Theo., only in characters of the male genitalia. The 

 side-pieces and their appendages rather closely resemble those of C. invidiosiis, but 

 the clasper is more evenly narrowed towards the tip. The unci are rounded at the 

 tip, the harpagones divided into two portions which have a very peculiar form ; 

 neither of them is toothed or subdivided. The harpes have the usual crown of spines, 

 but instead of a finger-like basal projection they have a large blunt prominence.

Although in general characters this species exactly resembles C. invidiosus, its 

 genitalia are much more like those of C. pruina, Theo. ; there are however good 

 specific differences. Dr. Ingram has obtained and distinguished larvae of all three 

 forms at Sunyani, and we have here therefore another interesting case of the correlation 

 between larval and male genital characters. 



Culex pacificus, sp. n. (fig. 4). 



(J. Head. Integument blackish, clothed with scales of the usual form : flat whitish 

 scales at the sides, narrow dark brown ones above ; upright forked scales light brown 

 in front, dark brown behind. Proboscis not quite as long as the abdomen, black- 

 scaled for the most part, but with a narrow and ill-defined pale ring just beyond the 

 median suture, most distinct on the under side. Palpi longer than the proboscis by 

 the length of their last joint ; long hairs on the last two joints few in number ; scales- 

 mostly black, but small patches of whitish ones at the bases of the last two joints on 

 the under side, sometimes just passing round to the upper side. Thorax : integument 

 blackish ; scales of scutum mostly dark brown, but there are a pair of roundish patches 

 of black ones towards the front ; and a suggestion of a pair of paler lines on the 

 posterior half ; scales of scutellum lighter. Pleurae with some inconspicuous flat 

 whitish scales. Abdomen black, the segments with white basal bands of even width ; 

 ventrally the segments have broad black apical bands. Genitalia : the side-pieces 

 are straighter than in most species of Culex, with long dark hairs above, and a patch
