Genus Anopheles. 
129 
Wings very much like A. Sinensis ; veins clothed with yellow 
and black scales ; the costa dark, broken by two small yellow 
spots, one near the apex and 
the other about a third of 
the length from the apex, 
the apical spot extending on 
to the first long vein and the 
upper fork of the second long 
T 
vein, the other spot passing 
on to the first long vein only; 
there is a yellow spot further back on the first long vein, which 
does not, however, reach the costa ; fringe just as in A. Sinensis . 
Length. — 5 to 5*5 mm. 
Habitat .—Katmiga and Sierra Leone. 
Date of capture .—January 27. 
Observations .—With the hind legs destroyed this species looks 
like A. Sinensis, but the white hind-tarsi readily distinguish it. 
From A. argyrotarsis it can at once be told by the wings, which 
have the fringe with only one pale spot at the end of the lower 
branch of the fifth long vein, whereas in A. argyrotarsis there are 
several pale areas ; and there are never more than two costal 
spots in this species. 
Dr. S. R. Christophers, who sends this species, says : “ It 
occurs very infrequently, and we have been unable to obtain any 
males.” It occurs widely distributed, but rarely, in the Sierra 
Leone swamps. This species has been shown on two occasions 
to contain sporozates in the salivary glands, though caught about 
a quarter of a mile from any human habitation.
