FOR TIIEIR DESTRUCTION. 
IN consequence of no Prize Essays having been received upon 
the subject of the Large Caterpillar which feeds upon the root 
of the Turnip, (being the larva of Agrotis Segetum,) it has been 
determined to continue the same as the subject of the Essays for 
the ensuing year, by the Entomological Society and the Agri- 
cultural Society of Saffron Walden ; by each of which So- 
cieties the sum of Five Guineas has been offered as a Premium 
for the best Essay upon this insect. 
The Essays must be accompanied by testimonials of the suc- 
cess of the remedies proposed by the writers, and must be for- 
warded to the Secretary of the Entomological Society (at 
No. 17, Old Bond Street), with fictitious signatures, on or before 
the Fourth Monday in January, 1840, when they will be referred 
to a Committee to decide upon their respective merits ; after 
which, with the permission of the Writers, both the Prize Essay, 
and any others of value, will be published. 
The Essays must be respectively accompanied by a sealed 
letter, indorsed with the fictitious signature adopted by each 
Author, and inclosing the real name of the Writer.
