 on the 7th of December, when leaves of Rumex pulcher 

 and R, crispus were substituted, and eaten by the larvae 

 with avidity, and the fact of the fourth moult being 

 their last was soon evident by their quickly attaining 

 the length of one and three-quarter inches when 

 stretched out, being asleep and hiding between the 

 leaves during daylight and coming out to feed only at 

 night; by the 15th they began to mature and were 

 very fat, and the biggest laid up on the 23rd to purge 

 itself of its grossness and fed no more, and becoming 

 reduced in bulk entered the earth on the 27th, the 

 spiracular stripe having faded almost entirely away. 

 The remaining two larvae underwent similar fading and 

 decrease of bulk, feeding however a few days longer, 

 and they entered the earth respectively on the 30th 

 and 31st of December.

In a cocoon one and a quarter inches long by seven-
