• Nest structure of two closely allied sympatric Ceratina bees, C. (Ceratinidia) japonica Cockerell and C. (C.) flavipes Smith was described. In Sapporo, both start new nests in middle May. The adults newly emerging in the fall either remain in mother's nest or make wintering nests where they stay to middle May. The nests are made by excavating pithy core of dry twigs or stems mostly standing upright on the ground. The summer nests have entrance constriction and turning chamber at the entrance. The cells are made successively from the bottom of the burrow like as the other congeneric species. The cell partitions are often omitted and there are often empty spaces between cells. Some consideration were given upon these features, being rather rare in solitary bees. Corresponding to the difference in average body size, the cells are slightly larger in C. japonica than in C. flavipes, that is, 9-12mm against 7-9mm in length and 3.5-4.0mm against 3.2-3.7mm in diameter. Otherwise, there is no remarkable difference in nest structure between two species.
