a. THE, OAK LEAF, GALL. FLY. 
CYNIPS QUERCUS FOLIL 
“The ANTLERs are hoop’d, and have a thick extremity. 
“The Trunk is bloated, and ftreak’d. 
This Infe& I received from Norway, where the oaks were in a 
- manner covered with it, in‘the months of July, and part of Auguft, 
1768 ; and in our own oak-woods I have feen fuch a Fly frequently ; 
and found it, tho’ differing a little in colour, perfe@tly the fame in all 
its characters. It is a ftrong, coarfe-made, and not very handfome Fly; 
and is flow and heavy in its motions: and is generally found fitting 
on the under part of a leaf, with its wings {pread out flat. 
Its HEAD is of a ruffet brown. 
The Eyes are blue. 
The Antlers are mottled, of black and chefnut colour. 
The Feelers are brown. 
The ‘Yaws are fharp, jage’d, and brown. 
Its TRUNK is of a raven grey, very beautifully ftreaked with white. 
Its Bopy is coal black. 
The Rags dividing the Joints are brown. 
The /ir-holes are dufky. 
Its Lecs are grey, with ftiff black hairs, and black toes; and the 
thigh is black. 
Its WinGs are of a pale brown, with a tinge of olive-colour; the 
Veins on them are deep grey. 
Its Tax is perfectly black. 
The Sting is chefnut brown. 
With us the Trunk and Body of this Fly are quite black ; other- 
wife there is no difference between fome I caught this year in Bufhy 
Park; and thofe I had from Norway.
