DiCHELiA GNOMANA, Lin. (Barrett, Ent. Mo. Mag., 

 vol. ix., p. 129). 



Three or more examples of this Tortrix are stated to have 

 been taken some fourteen or fifteen years since by a northern 

 collector, who cannot now remember the locality from which 

 he procured them. They were sent as T. costana to Mr. 

 Hodgkinson, who at the time considered them varieties of 

 the last-named species. Subsequently they duly found their 

 way into the collection of the Rev. H. Burney, who recently 

 forwarded them for examination to Mr. Barrett. 



Mr. Barrett's description of D. gnomana will be found in 

 the Novemlier number of the Magazine, in a truly interest- 

 ing and valuable paper on British Tortrices, the materials 

 for which have been got together with painstaking care and 

 shaped with patient thought. 



Mr. Barrett writes me that in his opinion gnomana^ 

 although placed by Dr. Wocke in the genus Dichelia, bears 

 no resemblance to grotiana, but is more nearly related to 

 semialbana and costana, though easily distinguished from 

 them by its ochreous-yellow colour, its peculiar broken 

 fascia, and the strongly marked spot before the apex. 



Dr. Staudinger considers that the insect which Hiibner 

 and Haworth Called gnomana is but a variety of Peronea 

 ferrugana, and that the gnomana of the Vienna Catalogue 

 is identical with Hlibner's strigana, but that Stephens, in 

 his "Illustrations" (4-162) correctly figured gnomana; he 

 therefore gives England as a locality for the species. It 

 also occurs in France, Germany, west and south-east of 

 Russia, Greece, and Andalusia, so that it seems to be pretty 

 widely distributed over the Continent.
