In a previous paper (Leeson 1937) it was shown that in East Africa there were variations in the wing markings of the type form of Anopheles funestus. It was further shown that larvae and pupae positively identified as typical A. funestus produced adults having these wing markings. Identification of the adults was confirmed by examination of pharyngeal armatures and male terminalia. The wing forms were then arranged in the following four groups:— Group 1: dark area at base of costa uninterrupted, 3rd vein with a pale interruption. Group 2: dark area at base of costa uninterrupted, 3rd vein entirely dark. Group 3: dark area at base of costa interrupted by one pale spot, 3rd vein with a pale interruption. Group 4: dark area at base of costa interrupted by one pale spot, 3rd vein entirely dark.
