A number of experiments were made during the spring and summer of 1908 in order to test the conclusions reached in a previous study of the origin and early history of the germ-cells in Calligrapha multipunctata and several other chrysomelid beetles. These experiments suggested some interesting hypoth esès which will be verified or disproved as soon as more material can be obtained. The work was begun at thc ZoOlogical Lab oratory of the University of Wisconsin and continued at the Marine Biological Laboratory, Woods Hole, Mass.,2 and at the ZoOlogical Laboratory of the University of Michigan. In a paper soon to be published3 I have shown that there is an intimate connection between the primordial germ-cells and a disc of granules lying near the posterior end of the eggs of Cal I:à §rapha multzbunctata, C. bià §sbyana, C. lunata and Leptinotarsa
