anticipated rae in the formation of this Genus, which contains 

 his division Palpance : a doubt is there expressed whether 

 they may not be varieties ; but the numerous specimens which 

 have since that time been collected leave little room for such a 

 conjecture, and the addition of the novelty figured (the only 

 one not described in the valuable work alluded to) renders it 

 still more probable that they are distinct. 



The present Genus, on comparison with Peronea, will show 

 how little attention has been paid to the conformation of the 

 Lepidoptera ; such differences in any of the other orders would 

 have been detected long since ; but I hope by the dissections 

 with which I shall always illustrate the subjects, that I may be 

 able to interest entomologists sufficiently to induce them to at- 

 tend to the structure of this beautiful order. 



The following are the species contained in this Genus : — 

 1 . S. degenerana Hub. 2. dilutana Hub. 3. Afzeliana Gmelin. 

 4. Lathamiana Gmelin. 5. 2JU7ictida7ia Hub. Bicana Fab. 

 6. ramosana Hub. They have been found at different periods 

 of the year at Darent and Birch Woods, Kent, and in the 

 New Forest. The rare and beautiful species, figured from the 

 collection of Mr. Stone, was beat off a tree in July 1823, at 

 Birch Wood, and another was taken off paling there, which 

 induced me to think, that like Peronea they might be attach- 

 ed to Lichens, but we are completely ignorant of their eco- 

 nomy. 



Lichen prunastri (Plum-tree Lichen), growing upon a branch 

 of a tree, is figured in the Plate.
