Circumstances of capture: — This species is by far the commonest 
mosquito in the Congo. It is seen almost everywhere in the bush, 
and lives equally well in grass country or forest. It always bites 
fiercely and feeds with equal readiness by day or by night. At Bamu 
Island, near Leopoldville, it was actually observed to pierce through 
canvas-seated chairs and even through the soft goat skin leather ol 
Madeira boots. It was noted in the diary of the Expedition as \er> 
unusual that no species of Mansonia were seen in the bush where 
camp was pitched for the night on the banks of the Congo a short 
distance above Lulonga. 
Adults were caught in the houses of Europeans and Africans in 
the day time and at night. They were taken from mosquito nets 
covering the beds of natives and whites and were raptured during 
the day on steamers, in the bush and on sand banks. 
Breeding places: —We were not successful in rearing the imago 
from the numerous larvae we had from time to time in the laboratory
