Since in the honey bee these lobes are, with reference to the poles of the egg, directed caudad and laterad, the optic lobes may be similarly described as derived from the lower and posterior border of the protocerebral lobes, although this is actually their upper (dorsal) and anterior border. As in other insects then development differs from that of the remainder of the brain. At Stages VIII and IX the ectoderm destined to form the optic lobes is not distinguishable from the other neurogenic ectoderm of the brain rudiment. During the succeeding stages the greater part of the latter becomes transformed into neuroblasts and gang- lion cells and the regular palisade-like arrangement of its cells altogether disappears. This does not occur in the region of the.
