every hope of success, as they are now about three weeks 
old, and have grown to a very large size.’ 
‘On the 16th of April larve began to spin, 39 days after 
hatching, and on the 15th of May my correspondent was 
preparing for the second generation. ‘Two live cocoons of 
a beautiful white silk and a skein of silk reeled from one 
cocoon were sent to me as samples of the produce obtained ; 
and here they are. I hope that the same success will attend 
the rearing of the following generations.”

Exhibitions, dc. 
Mr. F. Merrifield exhibited specimens showing the effects 
of temperature in the pupal stage on several species of Lepi- 
doptera. Vanessa polychloros was much darkened, especially 
towards the hinder margin, by a low temperature. Vanessa 
c-album showed effects on both sides, especially in the female; 
they were striking on the under side. Several examples of 
the striking effect produced by temperature on the summer 
emergence (prorsa) of Araschnia levana were exhibited. Some 
Vanessa to showed the gradual disintegration, by exposure to a 
low temperature, of the ocellus on the fore wing, which in the 
extreme specimens ceased to be an ocellus, and was a remark- 
able confirmation of Dr. Dixey’s views of the origin of that 
ocellus, as exemplified in the Plate attached to his paper 
in the Entomological Society’s Transactions for 1890,
