252 MEDICAL ENTOMOLOGY 



Thorax brown with silvery scales. Abdomen black with golden hairs. 

 Legs black with apices of all segments, except the last in the fore and mid 

 legs, with narrow white bands. Costa with three white spots, the apical 

 one large, the second smaller, and the third very small. From Angola. 



Anopheles (Pyretophorus) distinct us, Newstead and Carter. Palpi 

 with four white bands, the apices white. Thorax slate grey with a 

 dark median longitudinal line. Abdomen dark brown, with pale 

 golden brown hairs. Legs brown, lighter below ; fore legs with narrow 

 white apical bands on the metatarsus and first tarsal segments ; 

 middle and hind legs with pale areas at the articulations. Costa 

 mostly black with two pale spots ; these characters distinguish it from 

 any other anopheline. From the Luapala river, North-East Rhodesia. 

 A variety melanocosta is also recorded from the same locality, which 

 differs from the type in having the whole of the costa black, with 

 the exception of a small pale apical spot. 



Anopheles (Myzorhynchus) muritianus, Grandpre. Palpi with four 

 pale bands, the terminal one including the apex. Thorax dark brown 

 with dark longitudinal lines. Abdomen black, clothed with brown 

 hairs. Fore and mid tarsi with white bands at their apices, hind 

 tarsi banded with white apically and basally ; apex of first, most of 

 the second, and both the last tarsi of the hind leg banded or entirely 

 white. Costa black with two white spots, one near the apex. 

 This species is widely distributed in Africa and is said to be the 

 commonest anopheline at Nairobi. 



Anopheles (Myzorhynchus) umbrosiis, Theobald. Palpi black, without 

 any bands. Thorax black with traces of lines and with golden scales. 

 Abdomen grey with brown hairs. Legs brown, all joints with pale 

 bands. Costa black with a yellow spot at the apex. Found in 

 Southern Nigeria, Congo, Cameroon, and the Malay States. Edwards 

 states that A. (Myzorhynchus) obscurus, Griinberg, and A. (Myzorhyn- 

 chus) strachani, Theobald, are synonyms. 



Anopheles (sensu restricto) smithi, Theobald. Palpi black with three 

 narrow pale lands, apices black. Thorax grey with a dark median line. 

 Abdomen black with brown hairs. Legs brown and unbanded. Costa 

 black. From Sierra Leone. 



Anopheles (sensu restricto) niaculipennis, Meigen. This species is 

 chiefly European and is described on page 241. It is said to occur in 

 Tunis. 



Anopheles (sensu restricto) algeriensis, Theobald. This species is 

 probably identical with the European bifurcatus, (see page 241).
