I have studied the genitalia of male specimens from Ceylon and the Malay 

 States, and find them identical with those of African specimens.

Mansonioides africanus (Theo.). 



Panoplites africanus, Theo., Mon. Cul. ii, p. 187 (1901). 



Mansonia major, Theo., Mon. Cul. iii, p. 270 (1903). 



Mansonia nigerrima, Theo., Mon. Cul. v, p. 450 (1910). 

 The pale stripes of the thorax are twice interrupted, but more distinctly so in 

 some specimens than in others ; the thoracic integument is usually darker than 

 in M. uniformis, and the palpi ol the female have a much more distinct white 

 tip. The structure of the male genitalia is shown in the figure (fig. 2). As in 

 the case of Culex pipiens and C. fatigans, the genitalia of the two African 

 species of Mansonioides differ mainly or only in their basal parts (harpes and 

 harpagones). M. major was described from a flattened, but typical female 

 specimen. 



M. nigerrima may perhaps rank as a good variety ; it is much darker than the 

 type : the thorax is darker, with hardly a trace of pale markings ; the dark 

 scales of the wings are much more numerous than the light, and the white rings
