Professor Poulton said that this remarkable experiment 

 perhaps tended to support Col. Manders' suggestion that the 

 species could be influenced in the direction of the inaria form 

 by dry conditions ; but large experiments specially designed to 

 test this hypothesis were required before it could be accepted. 

 The distribution of the inaria form in Africa did not seem to 

 point in this direction. We did not yet know the conditions 

 of moisture or dryness under which these larvae and pupae had 

 been kept by Mr. Eogers. Whatever the interpretation,* the 

 results were extremely interesting, and contrasted in a remark- 

 able manner with those obtained by Mr. G. F. Leigh, F.E.S. 

 (Trans. Ent. Soc. Lond., 1904, pp. 689, 690, Plate XXXII). 

 The relative number of the females and the slightly earlier 

 average emergence of the males were interesting points 

 shown in the above table. 



MiJLLERiAN Mimicry in Euploeinae. — Professor Poulton 

 exhibited sets of Euploeine butterflies from Southern India, 

 the Solomon Islands, New Guinea, and Fiji, showing that the 

 pattern, which differed at each of these localities, was followed 

 by various local species. Two different patterns were shown 

 from New Guinea and two from the Solomons. The exhibition 

 was intended to meet the criticisms contained in a letter by 

 Lt.-Col. Manders, read at a recent meeting and now published 

 in the "Entomologist's Record" for May (pp. 120, 121). The 

 writer of this letter implied that the resemblances figured by 



* Mr. L. Doneaster, F. E. S. , who examined the series at the conclusion 

 of the meeting, suggested that the results may be due to the Mendelian 

 dominance of the inaria over the type form of female, the tendency to 

 inaria having been carried by the male parent. It would be of the 

 highest interest to test this suggestion by breeding from the first filial 

 generation (F. 1).— E. B. P., June 20th, 1909.
