The old genus Tortrix, containing at present nearly 350 British 

 species, is now with propriety considered a family, composed of nu- 

 merous groups, which it will be found impossible to understand 

 clearly, unless they be formed into genera : with this object in view 

 I have proposed the genus Peronea (derived from the Greek and 

 signifying a button), and divided it into sections, those with a large 

 elevated tuft of scales in the centre of the upper wings being the 

 typical species. I shall introduce Hlibner's sectional names from 

 his fanciful arrangement; but I may here state that as it is a mere 

 catalogue divided into groups, the markings of the wings being 

 briefly added, without any attempt at scientific definitions, I shall 

 never feel bound to adopt them. Although his section Lopas agrees 

 best with a portion of our division d. he has introduced into it one 

 of the true Peroneal (No. 15) as well as No. 47, at once proving the 

 instability of his characters.
