Extract

1. The ornamentation of the wings in Anopheles funestus, Giles, is variable.

2. Nine distinct arrangements of the wing scales were observed in a random sample of 1,084 individuals.

3. Nearly nine-tenths of the specimens occurred in one group, in which there were dark and pale forms.

4. Variations in wing markings are not solely related to sex or to habitat.

5. The pale form was more prevalent in the wet season and the dark form in the dry season.

6. It is suggested that further study may reveal whether the dark form is the hibernating variety and whether one form is more important as a carrier of malaria than the other, and that these details of wing ornamentation should be recorded in future.
