on its body or wing cafes. I have alfo obferved ir in 

 great plenty on the fcarabaeus ftercorarius Lin ; or 

 common black beetle, as well as on a fmall brown 

 variety of the fcarabgeus fimetarius Lin: which is 

 almoft always to be found in cow-dnng in the months 

 of April and May. 



The manner in which thefe minute infects adhere is 

 very curious ; for each is affixed by a flexible ftalk or 

 pedicle to the wing-fhells and other parts of the infect 

 they infeft ; fo that unlefs their nutriment is abforbed by 

 the ftalk which fupports them, (and which, in this 

 cafe, muft be tubular,) they muft have the power of 

 bending the ftalk in a femicircular direction at parti- 

 cular times, fo as to enable them to adhere occafionally 

 to the infect for the purpofe of feeding. They are 

 fometimes fo numerous as to prevent the beetles on 

 which they grow, from doling their wing-fheaths ; 

 and adhere to their limbs in fuch a manner as greatly 

 to impede their motions. 



The upper furface is fmooth and convex ; the lower 

 furface flat; but the figures annexed will convey a 

 clearer idea of the feveral particulars of their appear- 

 ance than any defcription. The two upper figures 

 reprefent the fore and back view of the infect. The 

 large groupe reprefents fix of them adhering to the 

 elytron or wing-lheath of the brown variety above- 

 mentioned of the fcarabaeus fimetarius. The other 

 figure (hews the lingular appearance of the jaws and 

 other parts at the head of the infect, magnified in a 

 much greater degree.
