THE YOUNG NATURALIST.

Dr. Sharp exhibited specimens of Cychramus luteus, and fungicola, auct., and stated 

 that they are the sexes of one species, C. luteus being the male, C. fungicola the female. 

 In working through the Central American Cychramini, he had found that in some 

 genera the males differed greatly from the females in size and sculpture ; but this 

 was not a constant character, for in some species, while certain males scarcely 

 differed from the females in these respects, others were so different that they would 

 scarcely be recognised as belonging to the same species. 



Mr. Edward A. Butler exhibited specimens of Platymetopius nudatus, Deg., from 

 Ewhurst, Surrey. He remarked that the species was recorded as having been once 

 previously taken near Plymouth by the late Mr. John Scott. 



Mr. G. T. Baker read a paper entitled, " On the distribution of the Charlonia 

 group of the genus Anthocharis." Mr. Baker stated that the species, six in number, 

 of this small division of the genus Anthocharis formed a very natural and closely 

 allied group, presenting many points of interest both in their relationship to each 

 other and in their geographical distribution, which extended from the Canaries on 

 the west to the valley of the Indus on the east. The author's theories as to the 

 causes of the present distribution of the group, which were based on geological data, 

 were discussed by Capt. Elwes, Mr. M'Lachlan, Mr. Distant, and Mr. Stainton. 



The Chairman read a paper entitled " On the genus Argynnis," which gave rise 

 to a discussion in which Mr. Distant, Mr. Jenner Weir, and Prof. Riley took part. — 

 H. Goss, Hon. Secretary.
