RESULTS A. Cytoloyical Studies Since there is in the literature some confusion with respect to the classification of the Coleoptera, based on the structure of the ovariole, the cytological findings are reported in some detail. In Pof'ilhts disjunct us the typical number of ovarioles is two per ovary while in Macrodactylus snbspinosus it is six. The histological structure is essentially similar in both species. Unless otherwise indicated, the following observations are based on studies of Popilius material. Historically speaking, each ovariole may be divided into two major regions— the germarium and the vitellarium. A longitudinal section of an ovariole is de- picted in Figure Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
