from these pests to his tent being free from natives and pitched 
away from native huts. Grassi and others have pointed out that 
Anopheles are fewer in the upper stories of houses than lower 
down. It has also been noticed that people living in the upper 
stories of houses are more or less exempt from malaria. My 
experience is, however, that Anopheles maculipennis prefers the 
upper rooms of a house. This year I took ninety-five in the 
bedrooms and bathroom of my home on the first floor, but never 
saw one in any room on the ground floor. Culex pipiens occurred 
above and below. 
The species I place in the genus Panoplites, including the 
Taeniorhynchus taeniorhynchus of Arribalzaga, the Culex titillans, 
Wlk., seems limited to riversides and swamps fed by running 
water (Dr. Lutz); they, rtnlike many mosquitoes, bite during the 
daytime, the bite being very painful. 
Woods and spinneys harbour such species as C. albifasciatus, 
Macq., whilst the genus Sabethes is almost exclusively limited to 
the depths of forests, hence so few are found in collections. Of 
the habits of Psorophora I know little or nothing, but probably 
Dr. Lutz will enlighten us later on on this point. 
Aedes do not generally attack man or animals, as far as 
previous observations go— Aedes, I mean, in the restricted sense. 
They are found especially in marshy spots, the borders of lakes 
and so forth. As, however, one species, Aedes fuscus, Osten- 
Sacken, has been sent in numbers from Canada amongst the 
instalments of mosquitoes received from J. M. Walker, I venture 
to think they may be blood-suckers. The members of the related 
genus Uranotaenia suck blood and live in swampy regions, so 
Dr. Lutz informs me, and so do the members of the new genera 
Wyeomyia and Aedeomyia. The former are almost entirely wood 
mosquitoes. 
Very different are the habits of Corethra and Mochlonyx , 
which feed exclusively on vegetation, the adults being provided 
with only a short proboscis, more like that of the Tipulidae than 
that of the Culicidae. LTnlike most Culicidae they inhabit the 
open country, heath and woods, and do not enter habitations 
at all. They are often to be found in great numbers along river 
banks and under the shade of overhanging trees, where their 
fragile bodies are protected from the wind.
