304 HISTORY OF GLANVILLE'S WOOTTON. 



Dryobius roboris, Linn. Taken by my father off 

 holly at Holnest, July, 1842. 



Before proceeding further I wish to call attention to 

 a very curious black parasite, about the size of a 

 mustard-seed, adhering to the side of various species 

 of the Homoptera, where the elytra joins the thorax. 

 Through the microscope it looks like a little black 

 bag. I think it must belong to the Acari. Not 

 having seen any account of it, I propose to call it 

 Homopterophagus Dorsettensis.
