274 THE ZOOLOGIST. 



Mr. W. C. Boyd exhibited varieties of Fidonia piniaria and Thecla rubi, 

 taken at Bournemouth on May 20th, 1893. 



Mr. C. 0. Waterhouse exhibited certain large galls on oak-leaves from 

 Mexico, one of which was apparently produced by a species of Cynipidce. 



Mr. A. Cowper Field exhibited varieties of Smerinthus tilim, bred 

 between 1890 and 1893, under varying conditions of temperature, those 

 which had been exposed to a lower temperature being much darker thau 

 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 Zygoma trifolii, including very 

 many yellow forms, all, with one exception, taken at one spot during the 

 latter half of May, 1893, 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 discussion 

 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. Chitty exhibited black varieties of the following Coleoptera from 

 the slopes of Ben Cruachan, N.B. : — Carabus violaceus and arvensis, 

 Pterostichus versicolor, Phyllopertha horticola, and Telephones jiguratus, 

 and stated that the latter seemed a permanent race, as it occurred both in 

 1892 and 1893. 



The President remarked on the great abundance of Coleophora laricella 

 in Gloucestershire, and stated that they were committing great ravages 

 among young larches. Lord Walsingham stated that he had seen young 

 larches at Carlsbad completely bleached by this moth. 



It was suggested by several Fellows of the Society that care should 

 be taken to observe the occurrence of second broods of insects during 

 the year. 



Mons. Wailly exhibited a collection of Lepidoptera, Coleoptera, and 

 Orthoptera from New Zealand. A discussion followed, in which Lord 

 Walsingham, Dr. Sharp, Mr. McLachlan, Mr. Durrant and others took 

 part. 



Mons. Wailly further exhibited cocoons of various silk-producing 

 Lepidoptera, and stated that the larva of Attacus pernyi, whose food-plant 

 is oak, had been reared in Trinidad on Terminalia latifolia. — W. W. 

 Fowler, Hon. Secretary.
