40 DR. BRACKENRIDGE CLEMENS' LETTERS. 



The other two specimens, for which I propose the name 

 Cosmopteryx Clcmensclla, differ from Gemmiferclla. in the an- 

 terior wings heing darker, the orange fascia is paler, not so 

 reddish ; its margins are pale golden, instead of silvery-violet, and 

 its hind margin is almost straight (this is very different from 

 Gcmmiferella) ; finally, the apical streak is continuous, not inter- 

 rupted, and of a silvery-white throughout. I shall describe this in 

 an early number of the " Intelligencer," in some remarks on the 

 extra-European species of the genus Cosmopteryx.* 



Anorthosia punctipennclla. This seems to be allied to Cleo- 

 dora, and I do not feel confident that it is generically distinct. 



Gelcchia agrimoniella. Allied to G. ligidclla and G. tcenio- 

 lella but quite distinct. 



G. ? roseosvffusella ; a true Gelechia, allied to G. dccurtella 

 (H.-S. Tineides, tab. 72, f. 539). 



G. Rhoifructella. This has considerable resemblance with 

 our Populella ; but the anterior wings are broader and blunter, 

 and the anterior segments of the body are not pale. 



G. ? rubidella. A true Gelechia, somewhat allied to G. erici- 

 nella, but smaller, and the anterior wings narrower. 



G. dctersclla. I am uncertain about this ; it is perhaps allied 

 to our moss-feeding G. affinis. The name detersella must be 

 altered, that name having been used by Zeller for a Sicilian species 

 of the genus (Isis, 1847). 



The genus Gelechia, as at present constituted, is very elastic 

 and includes a variety of slightly different forms. G. subocellea 

 is our most discordant species.

 Entomologica," vol. x., several North 

 American species of But alls. His 

 Basilaris, p. 230, is perhaps identical 

 B. matutclla. 1 with your Flavifrontclla, and his

 Stilbosis tesquclla. This is a very curious insect, resembling 

 in form of wing Asychna ceratella ; the ornamentation is more 

 like that of some of the Laverncc. 



Chrysocorys Erythriclla. This is a true Chrysocorys.
