ing arrangement of the species may be acceptable to those 

 who have a collection of this beautiful genus, and will enable 

 me to explain the affinities of the neighbouring groups when 

 they come under consideration. I have carefully examined 

 the palpi of every individual, and have to regret that many of 

 the species have only manuscript names, (all of which are 

 printed in italics,) an inconvenience which it is hoped will soon 

 be superseded by the completion of Mr. Haworth's Lepido- 

 ptera Britannica, which it is understood will contain a Supple- 

 ment in which all the new species will be described.

Tortrix favillaceana, asijiana, and tristana, would follow 

 P. Bi/ringerana very well, but the last joint of the palpi is not 

 concealed, otherwise they agree both in the proportion and 

 form of the joints ; and I suspect, if we admit these 3 species, 

 that T. logiana, ScJialleriana, nifana, borana, Asperana and 

 variegana must be admitted also. 



The unique and nondescript species figured (the natural 

 size of which is given with the dissections) was beat from 

 out the white-thovn, at the end of September 1823, in the New 

 Forest, and is now in the cabinet of Mr. Stone, whose un- 

 rivalled collection of this family I have been allowed to ex- 

 amine at my leisure, and through M'hose liberality I am enabled 

 to give dissections of this rare and valuable genus. 



These insects conceal themselves in the Lichen parictinus 

 (figured in the plate) when it grows upon the white-thorn, 

 and have nearly all been taken at Darent and Coombe Woods, 

 and in the New Forest, from the end of September to No- 

 vember, and even during January and February occasionally.
