 Zusammenfassung: The optic lobes of Diptera have been examined by variants of the Golgi-Colonnier selective staining techniques and by reduced silver procedures. All, bar one, of the elements described by the earlier authors (Vigier 1908; Zawarzin 1913; Cajal & Sanchez 1915) have been seen, in part or in their entirely, in these preparations. M any other forms, hitherto unrecognized, have been found. T heir perpendicular topographical relationships have been reconstructed in the optic lobe regions. Some lateral relationships have also been reconstructed between elements in regions whose columnar arrangement is clearly discernible in Golgi preparations; these include the lamina and the medulla. In the Diptera the projection pattern of the retina mosaic into the lamina neuropil involves complex chiasmata between the two regions (Braitenberg 1967); these have been confirm ed from these species. The retina-lamina mosaic is, essentially, homotopically preserved in the columnar medulla, via long visual fibres and monopolar cells. The medullary mosaic is preserved through its strata by transmedullary cells and the longest small-field amacrine cells. The mosaic is projected to the two regions of the lobula complex by class I cells (see part I). The organization of the tangential cell processes suggests that some of them may interact with large or whole field aggragates of the relayed retinal mosaic. Others, especially in the lobula, m ay interact with small oval or narrow strip-field aggragates. Although there are m any differences of neural form and number of neurons between species, both the Lepidoptera and Diptera have the same fundamental plan of neuroarchitecture.
