Length. —6 * 5 to 7 mm. ; of proboscis 3 mm. 
$. Antennae dark brown, faintly pale banded with dark

Habitat. —Durban, Natal (S. R. Christophers) (2. 13. 1899); 
British Central Africa (Dr. Daniels) (82); Mombasa (McKay) 
(76); Bonny (Annett); Salisbury, Mashonaland (Marshall) (79) ; 
Queensland (Bancroft). 
Time of capture. —January in Durban ; May at Mombasa

Observations. —Described from three 9 ’ s and one $ from 
Natal. It is a large mosquito, readily identified by the row of 
spots on the femora and tibiae and by the apically banded 
abdomen. Those from Natal and British Central Africa are very 
similar, but the 9 sent by Mr. McKay from Mombasa presents 
some minor differences, not of specific value however. This latter 
9 shows the basal white lateral spots on the abdomen very
