becoming full-fed in the June folloAving." The larva of rtifihis is described 
as green with a paler lateral stripe, and is stated to feed on various species of 
Bumex and on Polygonum bistorta. 
The typical form of this species was at one time common in the fenlands 
of England, but has not been seen in that country since about the year 1848. 
On the continent of Europe, C. dispar is represented by the form rutilus, 
Avhich occurs in France, Germany, and the South-east. This form is also 
found in Asia Minor, Armenia, and the Altai.
