Mr. Poulton's notes in 1885 upon 



11. A pupa of S. ocellatus was first weighed very soon 

 after pupation; in fact the larval skin was not 

 completely shuffled off its posterior end. The pupa 

 had only slightly browned in the median dorsal 

 region : — 



* The wing-cases are darkened all over thoroughly, though not 

 completely. 



I The incomplete darkening is now chiefly confined to the rings 

 between the abdominal segments.
