Exhibitions. 



Mr. G. J. Arrow exhibited a flower-frequenting beetle from 

 the Transvaal, illustrating a remarkable device for the cross- 

 fertilization of flowers, one of the front feet being tightly- 

 clasped by the curiously-formed pollinia of an Asclepias. Mr. 

 Arrow remarked that he had seen no similar instance amongst 

 Coleoptera, although in some insects the phenomenon was no 

 doubt familiar to those who had had opportunities of observ- 

 ation in the countries affected by these plants. Professor E, B. 

 Poulton stated that he had often found such pollinia attached 

 to Hymenoptera. 



Mr. W. J. Kaye showed a remarkable specimen of Agrotis 

 tritici, bearing a close resemblance to A. agathina. It had 

 been taken this year at Oxshott flying over heather in company 

 with agathina, and was a good example of syncryptic resem- 

 blance brought about by the common habit of resting on 

 heather. The specimen agreed with agathina in ground 

 colour; in the pale costa; in the distinct dark wedge-shaped 

 marks near the outer margin ; and in the distribution of the 

 stigmata. These characteristics are simply a strong develop- 

 ment of characters which recur in the species, and it was the 

 simultaneous development of all of them which gave the insect 

 its strong likeness to A. agathina. 



Mr. W. J. Lucas exhibited a specimen of Forfic.ula auricu. 

 laria taken by Mr. R. A. R. Priske at Deal in September 

 1905, having the left cercus normal, while the right was that 

 of va,r.foi'ci])ata. 



Dr. F. A. Dixey exhibited some specimens of African 

 Pierinae, and remarked upon them as follows : — 



"The recent visit paid by Dr. Longstaff and myself to 

 South Africa fell, so far as Natal and Rhodesia are concerned, 

 well within the limits of the dry season. I have brought 

 here for exhibition representative specimens of four species 

 of Teracolus, viz., T. annse, Wallgrn., T. onvphale, Godt.,
