Professor Poultois pointed out that the specimens captured 

 .n Dec. 3, 1<>. and 17 confirmed the conclusions derived 

 from a study of Dr. Carpenter's earlier captures in the same 

 island (Proc. Ent. See., 1911, pp. xci-xcv). Although Dr. 

 Carpenter had found that the Planema models were more 

 abundanl in the central forest area of Damba Island, yet oven 

 hero all except Planema paragea were outnumbered in his 

 collection by the respective mimetic forms of Pseuda 

 The proportions of these mimetic forms differed, as they did 

 in the jungle, from those of the mainland only twenty miles 

 aw. iv ; while on the island, in the forest as well as in the 

 jungle, transitional forms were far more numerous and also 

 more truly intermediate than on the mainland. It was 

 also noteworthy that out of four female Ps. hobleyi one 

 should have borne the colouring of the male. The examples 

 of Pi. paragea were all dark forms with the pale markings 

 tly reduced.
