[November 21, 1907 



of Mylothris agaihina. — W. G. Sheldon : A series of 

 Limcnitis pol'uli and ab. ireinnlac with intermediate forms 

 taken this year near Laon, and a series of Chrysophanus 

 hippotlioe from the same region, the females displaying a 

 wide range of variation for so restricted a locality as that 

 in which they were captured. — G. C. Champion : A fully 

 developed example of Mcsovelia furcata, M. and R., from 

 Slapton, south Devon, and Thaninotrizon ciiierciis from 

 Lynmouth, north Devon. — A. Harrison and Hugh Main : 

 A case of Aplccta iicbiilosa, arranged to show the great 

 range of variation of this species in Delamere Forest, with 

 series from Epping Forest, north Cornwall, and the New 

 Forest for comparison. — R. S. Mitford : (i) Two c? speci- 

 mens of Cryptocephalus hipuiictaliis, taken by him at 

 Niton, in the Isle of Wight, in July, these being two 

 forms of varieties well known on the Continent, but 

 hitherto found in Britain ; (2) Paracymus aeneus, 

 captured on the north Essex coast in June, 1898, thus 

 establishing the claim of P. aeneus to be regarded as a 

 British beetle ; (3) an example of the very rare Lathrobitini 

 rufipenne, taken at Niton, Isle of Wight, in July, 1906, 

 a specimen of the rare Ceuihorrhynchiis viduatus, taken 

 by him at Brading, Isle of Wight, in July, 1907, and a 

 specimen of Cis dentatus, taken at Sandown, Isle of 

 Wight, in July, 1906 ; this species, although well known 

 on the Continent, had never before been recorded in 

 Britain. — Papers. — A large series of Nycteribiidte (parasitic 

 Diptera) from Ceylon : J. E. Collin, — (i) Some butter- 

 flies taken in Jamaica ; (2) some butterflies of Tobago :
