110 A Monograph of Culicidae. 
Observations.—Dr. Theiler sends a single specimen (a ? ) of 
this species. It differs slightly from the Mashonaland specimens 
in having all the femora with white spots, and in that the white 
costal spots spread more evenly on to the first long vein, and that 
there is an extra white spot on the first long vein under the 
second large black costal spot. The three pale pleural stripes 
cannot be seen, probably owing to the specimen being damaged.

Anopheles argyrotarsis. Robineau-Desvoidy. 
The following note is sent by Dr. Low :—“ It appears to be 
rarer than albipes, breeding-grounds similar. Sometimes all 
bred from larvae turn out to be this example, and sometimes, on 
the other hand, albipes. In other instances mixtures are got. 
In British Guiana, at Rockstone, on the Essequibo River, eight 
examples caught in a mosquito net in the evening were all 
argyrotarsis. One example caught in the Barima River, about 
70 miles up from the coast, was also the same. Its habits are 
similar to albipes. It can act as a host for Filaria nocturna 
(Vincent). It is inefficient for Filaria demarquait.” 
Additional localities.—St. Vincent (Dr. Low) ; Dominica (Dr. 
Low); Para (Dr. Durham); Trinidad (Dr. Hewlett). The 
British Guiana specimens were taken on the Demerara and 
Essequibo Rivers ; the Trinidad specimens partly in houses.

The characters separating this from the former are so 
constant that I think it is probably a distinct species. 
Additional localities Dominica, St. Lucia, St. Vincent, 
Grenada, Carriacore (one of the Grenadine Islands), Trinidad, 
British Guiana (Dr. Low); Para (Dr. Durham).
