Mr. J. W. Douglas on the Genus Gelechia. 195 



XXXVII. On the British Species of the Genus Gelechia of 

 Zeller.* By J. W. Douglas, Esq. {Continued from 

 page 179.) 



[Read May 7th, 1849.] 



Sp. 21. Rufescens. 



Re. rufescens, Haw. 

 *G. Isabella, F. v. R. 

 Acomp. tinctella, St., Wood, 1244 (non H.) 



Mr. Allis has Haworth's specimens. 



Sp. 22. * Velocella. 



G. velocella, Tis., F. v. R. pi. 77, fig. 4, Z. 

 Lita velocella, D. 

 L. subsequclla, Tr. (non H.) 

 An. nebulea, St.? Wood, 1191 (non Haw.) 

 (non Ti. populella, H. 21.) 



This is certainly the nebulea of Stephens's Cabinet, but the 

 description in his " Illustrations" does not agree with it. More- 

 over, he says, " found in June in gardens within the metropolitan 

 district," whereas it is never known to be taken but in dry, sandy 

 places far from gardens, such as Jerry's Hill, Putney Heath, the 

 heath field at West Wickham, &c. in April, never in June ; I am, 

 therefore, doubtful if this be the species intended by Mr. Stephens. 

 Again, he gives as a synonym " Ti. populella, H.," which is a 

 widely different insect, not agreeing with his description at all, 

 and not found in Britain hitherto as far as I am aware; so the 

 name " nebulea, St.," adopted on the continent for Hiibner's moth, 

 because " populella" was already used by Linne, cannot remain 

 for it, and Treitschke's name " pinguinella" must be resumed. 

 Zeller says that velocella appears twice a year, in April and July; 

 I never saw the second brood. 



* Those species marked * are in the collection received from Herr Mann of 

 Vienna.
