"The attempt to justify the use of each generic name would not 

 only be out of place in a mere Catalogue, but would occupy too 

 much space ; it is, however, essential to allude to one or two 

 instances of apparent 'love of change,' as it is too frequently 

 termed, when one writer differs from another. Duponchel, in the 

 ' Annales de la Societe Entomologique de France,' vol. 3, p. 433 

 (1834), has a paper on the division of the Tortricidae into genera ; 

 his 13th genus Ephippiphora, p. 446, is therein characterized, and 

 T. dorsana given as the type ; and this generic name is accordingly 

 employed for the genus including dorsana and its congeners in the 

 following pages. Guenee, in his Eur. Mic. Ind. Meth. p. 42, em- 

 ploys Ephippiphora for scutulana and its allies, whereas only two 

 of Guenee's species are included by Duponchel therein, and those 

 placed at the end — one of them, foenella, being subsequently re- 

 moved by him to Paedisca, in which genus he includes nearly the 

 whole of the species enumerated by Guenee, under Ephippiphora. 

 This transposition of the names caused Guenee, as he adopts both 

 genera, to propose a new one for the true Ephippiphorae (Stigmo- 

 nota, G.) ; and as of course Duponchel's original name must be 

 restored to its proper position, the name Halouota is subsequently 

 proposed herein, for Ephippiphora of Guenee." . 



" One other instance only shall be noticed: — Treilschke, in his 7th 

 vol. p. 232, proposes the genus Grapholita, and divides it into two 

 sections A and B. Section B, including Petiverella, is synonymous 

 with Ephippiphora, and section A, as hereafter employed under the 

 name Grapholita, is converted by additions into Catoptria by 

 Guenee, while he employs Grapholita to designate those insects im- 

 properly forced into section A, by Treitschke in his 8lh vol., with
