Exhibitions. 



Dr. F. A. Dixey exhibited some butterflies from Natal which 

 had been presented by Mr. G. A. K. Marshall, F.E.S., to the 

 Hope Department at Oxford, and read the following note : — 



" It will be remembered that some few years ago Mr. 

 Marshall conducted certain experiments with a view to 

 ascertain whether the assumption of the wet- or dry-season 

 form of various African butterflies could be controlled by 

 exposure in the pupal state to artiBcial conditions of tempera- 

 ture and moisture. Some of the results of these experiments 

 were recorded and discussed by Mr. Marshall in Ann. Mag. 

 Nat. Hist., 1901, vol. ii, p. 398. Others were dealt with in a 

 paper published in Trans. Ent. Soc. Lond., 1902, p. 189. Most 

 of the material produced in the course of this research was 

 exhibited on the occasion when the last-named paper was read ; 

 the present specimens, however, though duly recorded in that 

 paper, had not then reached the Hope Department. They 

 were therefore not included in the comments added by me to 

 Mr. Marshall's account of his experiments, and they have not 

 previously been seen by the members of this Society. This 

 note and exhibit may accordingly be taken as a kind of 

 appendix to the paper in the 1902 volume of our Transactions. 



" The specimens now shown are as follows : — 



" (1) Four specimens of Crenis boisduvalii, "VVallgrn. 



"These form part of the series recorded by G. A. K. 

 Marshall in Trans. Ent. Soc. Lond., 1902, p. 206. They consist 

 of one £ reared under normal conditions ; tw r o 5 $ exposed 

 in the pupal condition to excessive moisture ; and one $ 

 similarly exposed to dry heat. They accord fairly with the 

 seven specimens of the same series, reared under correspond-
