This richly-coloured and variable insect is not very common, 

 although in some seasons it may be taken in plenty. The 

 varieties are, inter se, tolerably constant, the named ones being 

 L. Bceberana (that described above), L. Pavonana, L. rhombi- 

 fasciana, L. petrana (cuspidana of Haw. and Stephens), and 

 L. stictana. 



L. pavonana differs from the type (Bceberana) in being less strongly 

 marked, and in having the dorsal blotch shorter, rounder on its 

 inner edge, and of a darker colour, approaching plum -colour. 



L. rhombifasciana has an irregular rhombiform, dark-coloured patch 

 at the base of the anterior wings ; the dorsal blotch is ferruginous. 



L. petrana, Hub. (cuspidana of Haw. and Stephens), has also a dark 

 grey streaky patch at the base of rhomboid form, with a similar 

 coloured, but rather paler cloud at the apex, the middle portion 

 of the wing being rich ochreous. 



L. stictana : the ground colour of the anterior wings is of an 

 ochreous red, with the base slightly darker, and a few streaks 

 scattered over the surface. 



The imago appears in July and August throughout the metro- 

 politan district, also in the north and west of England, the 

 different varieties occurring at the same time and places. 



The larvae are to be found in the catkins of Sallows and 

 Poplars.
