In the pr sent study the chromosomes of seven species of the Coccinellidae and three species of the Chrysomelidae were reported upon with special regard to the morphological analysis of the chromosomes from the comparative viewpoint. The species under investigation and their chromosome numbers here established are given in the annexed table (Table 1). The relation between the species and the chromosomal constitution was the main subject to be considered in this study. The occurrence of the multiple X-chromosome was suggested in a species of the Chrysomelidae, Luperus discrepans.
