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

 treilliana), a pretty, rather slender Bomhyx^ has a golden yel-

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

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