lively, remaining as a caterpillar from six to eight weeks, 

 gradually shrinking and losing its colour, until it turned 

 to the pupa. It made a fragile shell of fine earth, oval 

 in form, and buried itself a short distance under the 

 surface. Full-sized caterpillars,^ taken on the 20th of 

 March, ceased feeding and turned to the pupa state 

 from the 1st to the 20th of May, emerging to the moth 

 on the 15th of June. In some specimens the process 

 of turning to the pupa took place on the journey to 

 England in a box, the caterpillars being covered lightly 

 with cotton- wool.
