1. One strain occur only inApis mellifica fasciata Latr. which dominates Lower- and Upper-Egypt. This contradicts Rotter's hypothesis (1921) in which he supposed that the Egyptian honey-bee is of different strains and that the honeybee of Upper-Egypt is more primitive than that of Lower-Egypt. 2. Apis mellifica fasciata Latr. obtained from seven different districts are quite similar in the characters investigated; a) biological characters: body weight, lenghth of the life-cycle, longevity and resistance to starvation, b) anatomical character: number of ovarioles of virgin queens, and c) morphological characters: length of the flagellum, length of the tongue, dimensions and cubital index of the fore-wing, number of hooks on the hind wing, length of the third sternum and dimensions of the first wax gland. 3. The tongue length of the workers of the Egyptian honeybee is more or less uniform in Lower- and Upper-Egypt. It does not differ also considerably in a given apiary.
