NOCTUIDiE.— GEOMETRIDtE. 



Having at length, though imperfectly, detailed some of the essential characters 

 of the indigenous genera of Noctuidse and Geometridse, so far as opportunities 

 of investigating the species have been afforded me, I shall endeavour to draw 

 up a brief artificial tabular view thereof from external, chiefly secondary, 

 characters, previously calling attention to the note at the foot of page 5, vol. i., 

 and to the general remarks upon the extreme difficulty (acknowledged by 

 all writers) of discriminating the generaof Noctuidse from the examination of 

 the perfect insects in my observations upon the family, vol. ii. p. 101; and I 

 may add, that as the tabular views of the genera are merely subsidiary, and as 

 in some of the genera the species are rather discordant, such genera are 

 referred to twice in the subsequent tables ; and characters depending upon 

 sexual distinction I have as far as possible avoided.
