 Noad Clark, a series of slides illustrating minute microscopic 

 structures ; Mr. Lucas, some slides of rare and local plants,

MARCH 22nd, 1906. 



Mr. Dennis exhibited an admirable photograph of birch 

 catkins. 



Mr. Harrison, on behalf of Mr. C. Oldham, exhibited 6* 

 examples of Cosmotrichc potatoria, with female coloration; one 

 specimen had a more or less black-scaled area along the 

 costa from the base of the wing. 



Mr. F. M. B. Carr exhibited several specimens of Asphalia 

 flavicornis from Scotch and S. English localities ; the latter 

 were distinctly lighter in general colour, while the former 

 had more strongly marked bands and were larger insects. 



Mr. H. J. Turner exhibited short series of Ercbia cpipsodea 

 and Phyciodes ismcria, and a specimen of Saiyrus ncphele 

 received from Mr. A. J. Croker, and taken at Redvers, 

 Assiniboia. 



Mr. Newman exhibited short bred series of Lcucania 

 vitcllina, Nyssia lapponaria ; and beautiful melanic forms of 

 Tephvosia consonaria and Boarmia gemmaria. 



Mr. Robert Adkin exhibited a specimen of Valeria 

 oleagina, Fab. He said that a good deal of controversy had 

 surrounded the few specimens of this species that existed in 

 the cabinets of British entomologists. Those who were 

 forming collections a century ago do not appear to have, as 

 a rule, kept very definite records of their captures. The 

 history of many specimens of the utmost interest to workers 

 of the present day is known, therefore, more by tradition 

 than from written records left by the actual captors of the 

 specimens in question, the art of labelling insects being but 

 little practised in those days. It is, therefore, often most 

 difficult to follow the history of many an old specimen with 

 any degree of certainty, and, indeed, the exact conditions 

 under which some of the little known and now extinct 

 species occurred are not always very clearly traceable. With 

 regard to this species, however, we appear to have a fairly 

 clear record of the capture of sundry individuals somewhere 

 about 1800; at any rate, it was figured as new to Britain in
