geograp]iical distiil)ution of each of the species of which examples 

 are shown is explained ))y means of a small map, with the regions 

 in which the insect is found marked in red. 



The following species of mosquitoes are exhihited, all known 

 to convey the parasites of malaria from man to man, and thus to 

 disseminate the disease : — AnoijJieles viacuUpennis Mg. (fig. 3,

Disregarding for the present the mosquitoes that spread yellow 

 fever and filariasis, these being dealt with in this guide-book 

 under subsequent headings, the visitor arrives at a selection of 

 " apparently harmless " mosquitoes — those which do not, or at all 

 events are not known to, disseminate disease, namely : — Anopheles
