Direct proof that the rhabdomeres contain visual pigment has not yet been given. Cells with rhabdomeres are the only kind which have been described in retinulas of insect dorsal ocelli. This is typical for compound eyes of insects as well, except perhaps for the occurrence of rudimentary retinula cells in many Diptera (Dietrich, 1909) and certain other insects (Hesse, 1908). In the compound eye of Limulus, however, retinulas contain an "eccentric cell," which has no rhabdomere, in addition to typical retinula cells (Demoll, 1914; Miller, 1957).
