The black grouse are infested with an insect called 

 by Linneus, Hippobosca avicularia (the Ornithomyia 

 avicularia of Leach.) 



Mr. Samouelle in his valuable Entomologists Com- 

 pendium, observes, page 142. 



" It is almost an established fact, that every species of 

 bird has its own parasite ; and there is no instance of the 

 same species of louse having been observed on two distinct 

 species of birds ; although some birds, (as the raven, oyster- 

 catcher, &c.) are infested with several species of parasites."
