Exhibitions, dc. 
Mr. W. C. Boyd exhibited varieties of Fidonia piniaria and 
Thecla rubi, taken at Bournemouth on May 20th, 1893. 
Mr. C. O. Waterhouse exhibited certain large galls on oak- 
leaves from Mexico, one of which was apparently produced by 
a species of Cynipide. 
Mr. A. Cowper Field exhibited varieties of Smerinthus tilia, 
bred between 1890 and 18938, under varying conditions of 
temperature, those which had been exposed to a lower tem- 
perature being much darker than those which had been 
exposed to a higher. Mr. Merrifield made some observations 
on the subject, and remarked that, as far as his experience 
went, no hard and fast rule could be laid down with regard to 
the production of the lighter or darker colourings, as a high 
temperature sometimes produced dark forms. 
Mr. W. M. Christy exhibited a series of Zygena trifolii, 
including very many yellow forms, all, with one exception, 
taken at one spot during the latter half of May, 1898, and 
belonging to one colony. Some of the specimens were more 
or less incomplete, both in structure and colour. Lord 
Walsingham, Mr. Merrifield, and others took part in the dis- 
cussion which followed. 
Canon Fowler exhibited cocoons and specimens of Coniatus 
suavis var. chrysochlora, Luc., taken by Lord Walsingham in 
great abundance on the flower-shoots of tamarisk in the West 
of Italy. 
Mr. A. J. Chitty exhibited black varieties of the following 
Coleoptera from the slopes of Ben Cruachan, N. B.:—Cara-
