Mr. Rayward exhibited a larva of Thecla w-album, just 

 spun up for pupation, on the under side of a leaf of wych- 

 elm, in a similar position to which he had almost invariably 

 found the pupae in nature. He also showed the fully- 

 developed pupa?, and pointed out how closely it resembled 

 a dark brown, crumpled, shrivelled portion of a leaf. He 

 pointed out the girth, which was normally about the centre 

 of the pupa, but in the larva just before the actual shedding 

 of the larval skin it was much farther forward. The larvae 

 were obtained at Chalfont Road.
