Mr. E. Saunders exhibited Amblytylus delicatus, Perr., a 
new British bug, taken at Woking. 
Mr. Jacoby mentioned that he had taken the larva of 
Vanessa cardui on a narrow white-leaved plant in his garden. 
Mr. Enock stated that out of a batch of two males 
and six females of the Hessian Fly kept together, all six 
females had laid fertile eggs, so that each male must have 
impregnated more than one female.

Exhibitions, éc. 
Mr. F. P. Pascoe exhibited a number of new species of 
Longicornia from Sumatra, Madagascar, and South Africa. 
Dr. P. B. Mason exhibited, for Mr. Harris, a specimen of 
Cherocampa nerii, recently captured at Burton-on-Trent. 
Mr. S. Stevens exhibited a specimen of Vanessa antiopa, 
which he caught in the Isle of Wight in August last. Mr. 
Stevens asked whether Mr. Poulton or any one else present 
could inform him why, in British specimens of this species, 
the border of the wings was almost invariably a pale straw- 
colour. A discussion ensued, in which Mr. F. D. Godman, 
Mr. M‘Lachlan, Mr. Kirby, and Dr. Mason took part. 
Mr. E. B. Poulton exhibited a living Jarva of Smerinthus 
ocellatus in the last stage, which had been hitherto fed upon | 
nut—an entirely new food-plant. Thirty eggs had been put 
upon the plant, but only two of the larve would eat it; of 
these one died at the beginning of the last stage. Mr. 
Poulton said the result was very interesting, as a further proof 
that the specialization of larve to certain food-plants largely 
grows up in the life of the individual, the young larva being 
comparatively free to choose. Smerinthus vcellatus is a very 
specialized larva, and is never found on more than two or 
three species of food-plant; hence the fact that over 6 per
