250 MEDICAL ENTOMOLOGY 



Costa with three small white spots, and a yellow spot at apex. This 

 species is found in Southern Rhodesia, and in the Transvaal. Ed- 

 wards states that it is often confused with Anopheles funestus. 



Anopheles (Myzomyia) culici fades, Giles. Edwards states that, 

 after examining a large series of typical culicifacies from India, he 

 regards A. ( Pyretophorus J sergenti, Theobald, as a synonym. For a 

 description of culicifacies, see page 229. It is found in parts of Algeria. 

 Anopheles (Myzomyia} funestus, Giles. (Plate XXXIX, fig. 2.) Palpi 

 with two white bands and white apices. Thorax dark brown at sides 

 and grey in middle. Abdomen blackish brown with light hairs. Legs 

 dark brown, metatarsi and tarsi with narrow apical bands, which are often 

 absent. Costa with four small yellowish spots, and sometimes two smaller 

 ones. Several varieties have been described; A. hebes, Donitz, is 

 probably only a variety, and Edwards states that it only differs from 

 the type funestus in having narrower wings, and pale scales on half 

 of the third vein. The variety subumbrosa, Theobald, has no pale 

 spots on the costa near the base, but has some pale scales in the middle 

 of the third vein ; the fringe spots are usually distinct. According to 

 Edwards, the species A. (Myzomyia) leptomeres, Theobald, is this 

 variety. The variety bisignata, Griinberg, has no pale spot near the 

 base of the costa, the third vein and sometimes also the fifth are 

 entirely dark, and the fringe spots are indistinct or absent. 



Anopheles funestus is widely distributed in Africa, being commonest 

 in West Africa ; it is a natural carrier of the parasites of malaria. The 

 larva has branched frontal hairs ; no hair on the shaft of the antenna. 

 The palmate hairs, which are present from the second to the seventh seg- 

 ments, are filamentous. They are nearly always found in clear water, 

 never in marshy or foul pools. 



Anopheles (Myzomyia} impunctus, Donitz. A little known species and 

 of doubtful position ; one specimen was obtained from Egypt. 



Anopheles (Myzomyia} hispaniola, Theobald. Palpi brown with three 

 pale bands, the apical one being very small, the greater part of the api- 

 cal joint black. Thorax slate-grey with brown sides. Abdomen blackish 

 brown, paler below. Legs brown, apices of femora and tibiae pale yel- 

 low, tarsi unhanded. Costa with five black spots, the basal part being 

 black. Edwards states that A. (Pyretophorus) myzomyfacies, Theobald, 

 is a synonym. It is found in Spain, Algeria, and the neighbouring 

 parts. 



Anopheles (Pyretophorus) chaudoyei, Theobald. Palpi with three 

 narrow white bands, the first two nearer one another than the second
