( 606 ) XXV. Pseudacraea eurytus hobleyi, Neave, its forms and its models on Bugalla Island, Lake Victoria, with other members of the same combination. By G. D. Hale Carpentee, D.M., Oxon., Member of the Royal Society's Sleeping-sickness Commission. [Read November 5th, 1913.] Plates XXXIV-XXXVI. The following is a complete account of all the forms of Pseudacraea eurytus hobleyi, their Planema models, and other mimics in the same group, which I caught on Bugalla Island in 1912 and January-February, 1913. I wish, firstly, to express my indebtedness to Prof. Poulton for the great help he has given me in the preparation of this paper, especially in the preparation of the plates, the arrangement of which is entirely due to him. It seemed best to pubhsh the results in tabular form, in spite of the greater bulk of such a paper, because by such means a graphic representation of the numerical differences between models and mimics is brought home to the reader as he sees the long array of blank spaces under the headings of the models. I have taken the opportunity of figuring, on Plate XXXIV, some of the most interesting transitional forms of Ps. eurytus hobleyi from Bugalla Island, and of showing the close relationship of a single female (fig. 11) to a typical West African female of eurytus, L., from the Lagos dis-trict, represented in fig. 12, with its model Planema epaea, Cram., in fig. 13. On Plate XXXV I have figured three of the most interesting of the famihes of Ps. eurytus hobleyi bred from known female parents captured on Bugalla Island. An account of two of the families, B and E (figs. 1-8), together with other synepigonic groups from the same locahty, has already been pubhshed in these Transactions (1912, pp. 706-16). The third family, J (figs. 9-16), is recorded in Proc. Ent. Soc. 1913, pp. ix-xi. These breeding experi-ments conclusively prove that all the forms of eurytus hobleyi tabulated in the present paper form a single interbreeding community. trans, ent. soc. lond. 1913. — part iv.
