5i° for fifty to fifty-six days, had lighter red bands, under- 

 side black, and the lighter markings intensified, making 

 a contrast of light and shade. Those subjected to cold 

 spring or autuma temperature of 45° for thirt>'-two to forty- 

 seven days, and subsequently to various temperatures from 

 54° to 90° for six to twenty-four days, showed a suffusion 

 of the white scales across the black, between the red band 

 and largest white apical blotch, and were sprinkled, but in a 

 lesser degree, over the apex ; the red band on the primaries 

 was broken up into four portions and considerably narrowed, 

 especially in one specimen. Another specimen had the bands 

 or primaries blotched with white ; whilst in another the 

 secondary bands were ochreous. 



Mr. Hawes exhibited the two forms of Pieris napi, L., 

 both bred from the same ? parent ; also examples of the same 

 species bred from larvae which had been fed on different food 

 plants. He stated that specimens from larvae reared on hedge 

 garlic and horse-radish were nearly a'.l lighter than those from 

 larvae fed on mignonette and watercress. 



Mr. Elisha exhibited two drawers, one of Coleophora and 

 the other of Nepticiila, showing the larval cases underneath 

 each species and labelled to show the time of appearance, 

 food plant of the larva, and other data. Mr. Elisha stated 

 that he had adopted this system for the whole of his collection 

 of the Tineina. 



Mr. Frohawk exhibited living larvae of Carter ocephalus 

 palcemon, Pall., and stated that the food-plants were generally 

 given as Plantago major and Cynosurus cristatus, but this 

 example was hybernating on Bromus asper, L. 



Mr. R. South exhibited a female specimen of Eriogaster 

 lanestris, L., bred by him, and which on taking off the board 

 he noticed had ova showing between the segments of the 

 abdomen ; it was quite possible that the ova h d been ferti- 

 lised, as there were two males in the cage at tl e time the 

 female emerged. Mr. Barrett expressed an opinion that the 

 ova were sho\ying through a transparent membrane ; but Mr. 

 Weir said the eggs appeared to him to have ruptured the 

 integument. 



Mr. Tutt exhibited, on behalf of Dr. Chapman, examples 

 of several species of the genus Tceniocampa, taken from pupae 

 which had been cut open, so as to show the development of 

 the imago at the time of opening them. Mr. Tutt stated 

 that pupae had been opened in some cases as early as the 

 25th October, and in all cases the moths were found to be 

 fully developed and ready to emerge.
