F. N. PIERCE, F.E.S. 



Comprising 100 pages and 32 plates ol 350 figures.

 of Noctuidae, occurring in the British Islands 



FIGURED AND DESCRIBED FOR THE FIRST TIME, 

 THROWS A NEW LIGHT ON CLASSIFICATION. 



The WORK IS ENTIRELY NEW, nothing of its kmd having 

 ever been attempted with the British Noctuidae, and the exceeding 

 beauty of the structures will come as a suprise to the many who 

 only know Lepidoptera by their wing markings.

*' The structures are within my experience absolutely 



invariable within Specific limits." 

 " Invaluable in settling questions."
