GENUS ANOPHELES 315 



two or three of the anterior longitudinal junctions. Tarsal joints, 

 with the upper two of the fore and mid and the upper four of the 

 hind legs apically white banded. Thorax black with irregular 

 lines of white scales ; the pleurae with three brilliant white, 

 parallel, longitudinal lines. Abdomen black, densely clothed 

 with scales, which are so dense at the sides of the posterior 

 borders of the segments that they project as conspicuous tufts. 



Head black, a few of the anterior forked scales white ; palpi deep 

 brown, densely hirsute, with three indistinct whitish bands. Legs with 

 the femora and tibiae banded and mottled with patches of white scales. 

 The characters of this species are so striking and exceptional, that it can 

 hardly be mistaken for any other except An. Pharoensis, which wants 

 the pleural stripes, or for An. ocellaius, in which the lateral tufts of the 

 abdomen are ventral, and not dorsal in origin, and the thoracic spots are 

 too prominent to be easily overlooked. Length. — 5 to 5"5 mm. 



Habitat — Mashonaland, and British Central Africa.

Plate ix, fig. 5a, Wing of J ; 5b, Dorsum of thorax. 



Wings quite hyaline, with the white costa interrupted with 

 four obvious black spots, the largest just inside the transverse 

 veins, and between it and the next an additional black dot. There 

 are only eight or ten long black dots on the long veins, and the 

 internal fringe is cream-white, interrupted by half-a-dozen patches 

 of white scales. Last hind tarsal and apex of next whitish. 

 In the fore legs the last three joints are all dirty white but 

 for a faint darkening of their bases. All other tarsal joints 

 apically banded whitish. Thorax straw-coloured, with a patch 

 of velvety grey bloom on the dorsum and three black spots, one 

 in front of scutellum and the others lateral. Abdomen greyish- 

 brown, with yellowish hairs and dense tufts of long scales 

 projecting from the sides, even when viewed from above, but 

 springing from the ventral surface. 



Head with fawn ground and strong white frontal tufts, tlie fork-scales 

 of vertex white, but those of the nape bluish, while the lateral patches of 

 flat, imbricating scales are of a rich brown ; palpi fawn at the base and 

 white for their apical halves, the latter portion showing two distinct but 

 narrow black bands and the basal three, but less sharply defined ; pro- 

 boscis deep brown at the base, fading off to rich ferruginous on its apical 

 half, near the tip of which is a tiny black band. Abdomen deep brown, 

 densely clothed with ferruginous hairs and scales. Venter denselj' 

 clothed witli ferruginous hairs ; the posterior borders of the segments 

 clothed with dense tufts of elongated scales, with broad obovate ends, 

 a character which, taken in conjunction with the dense clothing of scales
