As " Stephens' Illustrations" had never been heard of when this 

 genus was established, I should have described the species before, 

 had I not been assured that Mr. Haworth would do so in his Ap- 

 pendix to Lep. Brit. : however, this second edition enables me to cha- 

 racterize all the species hitherto published and ten others not noticed 

 in the " Illustrations," and to correct many errors hitherto over- 

 looked. To the liberality of Mr. Bentley I am indebted for the free 

 use of his splendid collection of this beautiful genus as well as for 

 his sensible remarks on some of the groups. 



The Peronese measure from about 9 to 10 lines when the wings 

 are expanded ; most of them conceal themselves in the Lichens that 

 cover the old white-thorns, &c., and they have nearly all been taken 

 at Coomb, Birch, and Darent Woods, in Kent, and in the neigh- 

 bourhood of Brockenhurst in the New Forest.
