A number of this species f rom Bathurst, many of them caught in the barracks, prison, and police 
quarters, Government House ; some bred from larvae obtained from a large pool sixteen to eighteen 
leet in diameter. 
The specimens show some variation in regard to the intensity of the costal spots and leg 
ornamentation. One very marked melanic variety occurs, which is described below. The specimens 
were taken in October, November, and December. None were found at Baia or McCarthy Island. 
At Bathurst, Dr. Dutton only obtained A. costalis and a few A. pharoensis. I'heo. This species also 
occurs at Cape St. Mary, seven miles from Bathurst, where there are a few artificial breeding-places. 
Colonel Giles has described as a distinct species a specimen of A. costalis sent me from Gambia by Dr. 
Budgett. 
Ia. Anopheles costalis. Loew 
Variety melas 
Thorax dark brown to almost black, with narrow-curved pale golden scales as in the type ; palpi, 
with four pale bands, very narrow ; the fourth on the apex of the palpi, very seal}' at their base ; the two 
apical bands are close together, but quite distinct. Abdomen deep black, with pale hairs, golden at the 
apex. Legs prominently black, spotted and banded ; forelegs with a trace of pale spots on the femora 
as in the type, pale spots on tibiae, and a narrow band-like spot on the metatarsi, a yellow band involving 
both sides of the joints at the metatarsus and first tarsal, and at the first tarsal and second tarsal ; in the mid- 
legs the tibiae are spotted, but the tarsal banding is not distinct, nor are the tarsi banded in the hind 
legs, and the tibiae and femora spots are not so well defined.
