212 THE ENTOMOLOGIST. 



species be noxious) must show the results of actual experi- 

 ments made for the prevention of their attacks or the destruc- 

 tion of the insects themselves. The Essays must be sent to 

 the Secretary, at No. 12, Bedford Row, with fictitious signa- 

 tures or mottoes, on or before the 31st December, 1865, when 

 they will be referred to a Committee to decide upon their 

 merits ; each must be accompanied by a sealed letter in- 

 dorsed with the fictitious signature or motto adopted by its 

 author, and inclosing the name and address of the writer. 



Mr. Bond exhibited specimens of a gall found on a willow 

 tree near Cambridge ; the tree was fifty feet high, and almost 

 every twig appeared to possess its gall, which took the form 

 of a premature terminal development of leaves in whorls, so 

 as to resemble a flower-head. He had observed the galls 

 only the day before the Meeting ; the leafy excrescences 

 were then dry and withered, and he was unable to state what 

 was their colour when fresh. 



Mr. Saunders remarked upOn the similarity between this 

 and the Swiss gall which he had exhibited at the Meeting of 

 November, 1864 (Zool. 9377), in which, however, the leaf- 

 like processes were not spread out, but were adpressed to the 

 stem. 



Mr. Bond also exhibited vai'ieties of Colias Edusa and Va- 

 nessa Urticae, both captured in Norfolk or Suffolk ; each 

 was remarkable from having the wings, particularly the hind 

 wings, conspicuously blotched or suffused with dark patches. 



Mr. T. W. Wood exhibited a variety of the male of Apa- 

 tura Iris, captured in Kent ; it was remarkable for the ab- 

 sence of the usual white markings on both the upper and 

 under sides of the wings. 



The President read a note on generic names having nearly 

 the same sound, in which he expressed a decided opinion 

 that such names need not be changed. 



Mr. M'Lachlan read " Trichoptera Britannica ; a Mono- 

 graph of the British Species of Caddis-flies." In this paper, 

 the result of five years' study of the group, the author gives 

 detailed descriptions of 124 species, arranged in 43 genera, 

 and full accounts of the habits of the same, so far as they are 

 known to the present time.
