Mr. H. St. J. Donisthorpe exhibited an example of Oxypoda sericea, Hear, taken 

 in Dulwich Wood, June I7th. 1904, a species new to Britain ; also O. nic/rina, Wnt., 

 with a type lent by Mr. E. A. Waterhouse, to demonstrate that it is not synonymous 

 with O. sericea as stated on the Continent ; and O. exigua, which is also there re- 

 garded as synonymous with 0. nigrina. Mr. Hugh Main and Mr. Albert Harrison, a 

 long series of Colias edusa, with var. helice (bred from one $ helice by Dr. T. A. 

 Chapman from the south of France) to show the proportion of type and variety 

 obtained ; they also showed the results of similar experiments with Amphidasys 

 betularia, bred from a cj var. donbledayaria, atid a type ? taken in cop. at Wood- 

 ford, Kssex, in 1903. Mr. R. Priske, a specimen of Relops striatus, with a photo- 

 graph showing an abnormal formation of the right antenna, which was divided into 

 two branches from the fifth joint. Mr. Percy H. Grimshaw, examples of Hydrotsea 

 pilipes, Stein, <? and ? , the latter sex being previously unknown, and specimens of 

 Hydrotasa tubercula, Rond., not hitherto recorded in Britain, captured by Mr. C. 

 W. Dale and Dr. J. H. Wood in various localities. Dr. F. A. Dixey, some cocoons 

 and perfect imagines of hybrid Saturniids, including $ and ? of S. pavonia, L., x 

 •S'. pyri, Schiff., with added specimens of both sexes of the parent forms for com- 

 parison, the cross product resembling a large iS. pavonia, rather than a small S. 

 pyri ; the exhibit further included three <J $ and three ? ? , of which the ? parent 

 was S. pavonia, and the i parent a hybrid between S. pavonia J and -S. spini ^ , 

 viz., the cross product to which Professor Standfuss has given the name of <S. borne- 

 manni. These six individuals had been reared from ova supplied by him, and Dr. 

 Dixey gave an account of their life-history; the remaining four examples of the 

 hybrid = S. schaufussi, disclosed far less strongly marked sexual differences than 

 in IS. pavonia. Prof. E. B. Poulton, groups of Synaposematic Hynienoptera and 

 Diptera captured by Mr. A. H. Hamm ; three broken specimens of Papilio hesperus 

 taken at Entebbe in 1903 by Mr. C. A.Wiggins, showing that the tails of a Papilio, 

 if untouched by enemies, can esulure a great deal of wear ; and Nymphaline butter- 

 flies from Northern China, appai-ently mimetic of the male Hypolimnas misippus, 

 which is not known to occur in that region. The President, a number of examples 

 of Pyrameis atalanta, illustrating the effects of cold season breeding by Mr. Har- 

 wood of Colchester, some of them lent by Mr. R. S. Mitford.
