INTRODUCTION. 
The principal object of the present Catalogue has been to give 
a complete list of all the Tortrices that have been recorded as found 
in Great Britain, indicating at the same lime those species that are 
contained in the Collection. 
This Catalogue has been prepared by Ja mes Francis Stephens, 
Esq., so well known for his works on British Insects, for the extent 
of his cabinet, and the liberality with which he allows it to be 
consulted. 
Mr. Stephens has endeavoured to arrange these insects according 
to their natural affinities, so far as is practicable with a local col¬ 
lection ; and has taken great pains to ascertain every name which 
has been applied to the respective species and their varieties, the 
author of the same, and the date of publication ; the references to 
such names as are unaccompanied by descriptions being included 
in parentheses : all are arranged chronologically, excepting those 
to the illustrations and to the figures, which invariably follow their 
authorities. With these exceptions it has not been attempted 
to give the synonymy, from the impracticability of so doing within 
moderate limits; they may be found quoted at length, up to the 
period of its publication, in Mr. Stephens’s ‘ Systematic Catalogue 
of British Insects,’ 8vo, 1829. 
The species in the British Museum Collection are indicated by 
the letters, B. M., annexed ; while those in the Synoptic List, to
