on arriving, to find that it had escaped through a hole in the 

 net ! I have obtained specimens of between thirty and forty 

 new species of moths, of which I shall only mention such as 

 are remarkable for beauty: The Coerulean (Ctenucha La- 

 treilliana), a pretty, rather slender Bombyx, has a golden yel-

 Gooseberry (Ribes Cynosbati), I took several spinous cater- 

 pillars, which are light-coloured, with dark transverse spots. 

 One of them has since suspended itself by the tail, and
