Summary
Intracellular monophasic action potentials were led off from single photoreceptor cells of the compound eye of the drone bee in response to light of wave lengths varying from 318 to 650 mμ. Measurements of the heights of the peaks of the depolarising potentials showed the presence of two types of receptors with maxima in the sensitivity curves at 340 mμ, and 447 mμ, respectively.
The optimal sensivity at 447 mμ, agrees: with the absorption curve of isolated photopigments of the eye of the bee described by Goldsmith, with that of the maximum color sensitivity of the drone eye in visible light as determined by Goldsmith from the ERG, as well as with the curve of the intensity of radiation of the blue sky.
