 ftreaks, which defcend along the Shells from the bafe, and unite 

 near the apex. 



Its colours are more or lefs beautiful as the Infe6l is healthy or 

 fickly ; and as it dies, the colours gradually perifh ; the fplendor of 

 gold is no longer vifible than life is retained, it changes to green ; 

 from green to a brown, which fcarcely appears through a faint tinge 

 of blue, and in a few hours it changes altogether to a rufty brown 

 colour. 



This Infeft is admirably protected from external injury by the 

 fmgular form of its Thorax and Shells, which are alfo fo large as to 

 conceal every other part when the Infedl walks.
