well ( Veronica chamcedrys). They generally issue 
from the egg towards the end of the autumn, and 
pass the winter before they undergo their final me- 
tamorphosis. To protect themselves against the ri- 
gour of that season, they assemble in little colonies, 
and form a kind of tent, by drawing together a few 
of the leaves of the plant on which they feed, and 
covering the whole with a web of silk. The butter- 
fly appears in June, but in this country it is by no 
means of frequent occurrence. It has been found, 
however, rather plentifully in the Island of Wight, 
also near Dover, and in a few other places in the 
southern parts of England. It is abundant on the 
Continent.
