86 ENTOMOLOGY FOR MEDICAL OFFICERS 



As a "subgenus" Nyssorhynchus cannot be sharply 

 differentiated from Neocellia and Cellia, and but for my 

 inveterate reluctance to meddle with names that have become 

 generally current I should unite the three " subgenera." 



I. African Species. 



Anopheles {Nyssorhynchus') maculipalpis, Giles. Mauritius 

 West Africa, and South Africa. Palpi black, with a few 

 white spots, a narrow white band, and two broad white 

 bands, one of which is terminal. Legs black, with abundant 

 and regular white bars ; in the hind legs the 3rd, 4th, and 5th 

 tarsal segments, and the terminal half of the 2nd are white. 

 Wings dark, with white spots, four or five of which, of very 

 small size, are on the costa. Abdominal scales confined to 

 the terminal segment and genital lobes. 



Anopheles {Nyssorhynchus) pretoriensis, Theobald. Trans- 

 vaal and Natal, is perhaps only a variety of maculipalpis, 

 from which it differs in the following not very constant 

 points: — (i) the palps, though banded in the same way, 

 are not spotted ; (2) the ist tarsal segment of the hind leg 

 has a broad white terminal band, and the first of the three 

 white segments has a black basal band. 



Anopheles {Nyssorhynchus) aureosquamiger, Theobald 

 { = Pyretophorus aureosquamiger, Theobald). Transvaal. 

 Palpi with three white bands and white tip. Legs deep 

 brown, profusely spotted with yellowish-white; in the hind 

 legs there is a white spot at the tip of the ist tarsal segment, 

 a broad white band at the distal end of the 2nd, and the 

 greater part of the 3rd and all of the 4th and 5th are white. 

 Wings dark ; costa black, with three small white spots, not 

 including a minute spot on the tip. In the only perfect 

 specimen at the British Museum there are no abdominal 

 scales at all ; but the scales of the scutum and scutellum are 

 short broad elliptical scales, and the species is undoubtedly as 

 closely as possible related to maculipalpis and pretoriensis. 



Anopheles {Nyssorhynchus) brunnipes, Theobald. Angola. 

 Palpi with two narrow white bands and broadly white tip. 

 Legs dark brown, not speckled. Costa black, with two very 

 small yellowish-white spots followed by three larger ones. 

 No abdominal scales at all.
