CULICID^: THE ANOPHELES MOSQUITOES 79 



Anopheles {Arribahagid) lutzii, Chagas { = Manguinhosia 

 lutzii, Chagas). Brazil. The last 2 segments of the 

 abdomen and the genital lobes are covered with broad 

 white scales, and a few scales of the same kind are scattered 

 on some of the other segments. Wing-scales lanceolate, 

 brown and white, the former forming spots ; on the front 

 edge of the wing there are two large black blotches and two 

 small black spots, the colour of which is partly contributed 

 by a staining of the wing itself Legs yellowish-brown, the 

 tips of the tibiae and the intertarsal joints pale. Scutum with 

 three well-defined brown spots, the largest of which invades 

 the scutellum. 



Anopheles {Arribalzagid) bolivensis, Theobald {^ = Kerteszia 

 bolivensis, Theobald). Bolivia. The abdomen is "clothed 

 with rather irregular large black scales." Palps black and 

 shaggy, with two narrow yellow bands and yellow tip. The 

 proximal 2 or 3 tarsal segments are banded or spotted. Five 

 yellow spots on the front edge of the wing, one of them being 

 at the tip. The scutum has four brown stripes — two straight 

 down the middle and a somewhat sinuous one on either side. 



Subgenus Myzomyia, Blanchard (Gr. iui.v^eiv = to moan, 

 or to suck ; fivia = fly). 



Including Myzomyia, Feltinella, Neomyzomyia, and Pyrefophorus of 

 Theobald's Monograph, and Nyssomyzomyia, James. 



There are usually some distinct scales on the pronotum 

 and front part of the scutum, but the main vestiture of the 

 scutum consists either of hairs (series Myzomyia) or of narrow 

 curved scales (series Pyretophorus). There may be a few 

 narrow scales on the genital lobes, or even on the terminal 

 segment of the abdomen, but the main vestiture of the 

 abdomen consists of hairs. The wings are almost always 

 profusely mottled or spotted, and the costa is barred or 

 banded with numerous alternate dark and light spots or 

 streaks. The wing-scales are generally narrow. Palpi 

 slender. 



The species are usually small, are numerous, and are most 

 abundant in the Ethiopian and Oriental regions, although 

 they are also represented in the Palaearctic Region and just
