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.
