flowers of turnips which have been sowed for seed, a great 

 many of the identical fellows will be found skipping about the 

 cloths over which you shake them ; I do not mean the little 

 beetles, which are dark green, about the same size, and fly 

 very easily, but the real turnip-beetle. (I send you specimens 

 of both.) The flying-beetle is very common in all flowers 

 that produce a good deal of pollen ; I have seen fifty or sixty 

 in a dandy-lion.'' The real turnip-beetles do not eat pollen. 

 If you can stick in this note at the end of my turnip-fly 



epistle pray do so. — Lord F 's beetle is a weevil ; he has 



nothing to fear from it ; if it strip the leaves off' his beech- 

 trees one year it will not do so the next. I well recollect, 

 some years ago, seeing the fine beech-woods about Gloucester 

 completely stripped by it in the middle of June ; the next year 

 the woods were as healthy and luxuriant as ever. The weevil 

 appears and disappears without any known cause, like all other 

 insect pests, and these irregular visitors are always diflScult to 

 deal with ; I shall try, notwithstanding, to trace its habits, and 

 shall feel much obliged for any further information his lordship 

 may transmit through you.
