the latter species having been forced so as to cause it to 

 emerge at the same time as A. strataria. Mr. Tutt also 

 exhibited Caradrina ambigua, Fb., from Deal, and typical 

 specimens of C. taraxaci, Hb., C. superstes, Tr., from Sligo 

 and C. superstes, H.-S., from Yarmouth, Isle of Wight, and 

 made some observations upon his exhibit. 



Mr. Hawes exhibited a sketch of Euchloe cardamines, L., 

 at rest on a blade of grass, and pointed out that its position 

 was well adapted for keeping off the rain. 



Mr. South exhibited specimens of Vanessa antiopa, L., 

 from various parts of the palaearctic region, including India, 

 China, Japan, Germany and France, and remarked that the 

 American form was usually considered to present a more 

 dusted appearance on the border, but that in some of the 

 specimens from France now shown it was quite as much 

 powdered as in any American specimens he had seen. 



Mr. T. D. A. Cockerell exhibited Vanessa antiopa, L., van, 

 the margins more irrorated with black, from Wet Mountain 

 Valley, Colorado, The question of white and yellow 

 bordered specimens was discussed, Mr. Cockerell saying that 

 it was thought that the white-bordered specimens were 

 hibernated ones. Mr. Adkin stated he had bred the species 

 from American ova, and the borders were distinctly yellow. 

 Mr. Barrett stated that in what was commonly called the 

 Antiopa year (1872) all the specimens which he saw had white 

 borders. Mr. South said that two Welsh specimens he saw 

 had yellow borders. Mr. Tutt stated that he had seen five 

 specimens (British), three of which were white and two 

 yellow. Mr. Frohawk said that his sister had sent him a 

 specimen from Brooklyn Park, New York, which had a pale 

 border, and further said that on August 22, 1888, he had 

 seen a specimen then recently taken which was quite yellow. 

 Mr. Cockerell said it was a question whether the colours of 

 living insects faded, and he did not know of any decisive 

 evidence on the point. Mr. Barrett said the question was ex- 

 emplified in the instance shown at last meeting of an insect 

 turning from green to orange, viz., Lobophora viretata, Hb. 

 Mr. Frohawk stated that the pigment of some insects was 

 removable. He had had a species of Catagrainnia, which, 

 on being relaxed, left a distinct deposit of colour on the 

 blotting paper on which it was laid. Mr. Barrett pointed 

 out that Procris statices, L., become coppery red under such 

 conditions, but afterwards went back to its normal green 

 colour. 



Mr. R. South exhibited Cidaria suffuntata, Hb., bred from
