ber of larvae which were ascending a trunk of elm to undergo pupation, 

 and describes one of them as w^ell as the cocoon, ascribing them to his 

 N&pli. undulatclla, but he did not succec^d in rearing them to the 

 perfect state. 



Hypochalcia ahenella, S.Y. — The larva is still unknown. As Dr. 

 Eossler states that it forms tubular galleries on the lower leaves of 

 HeliantJiemum vulgare, according to Anton 8ohmid, I wrote to the 

 latter, who informed me that the larva mentioned above as feeding on 

 Helianiliemum was that of Hreplda compositeUa, and not that of 

 alienella, with which he was unacquainted. 



The species is indicated in the Vienna Catalogue simply by the 

 words : — " 32. Grlanzeuder schwarzgrauer Schabe. T. ahenelJa,'' which 

 diagnosis might suit many other Phycitidce, and, unfortunately, when 

 Zincken wrote his monograph of the genus Phycis, no specimens 

 existed in the collection of Schiffermiiller and Denis. Fischer v. 

 Roslerstamm, it is true, stated that he had seen under the name of 

 (Bneella in the Vienna collection a good male specimen of alienella ; 

 von Charpentier and Treitschke did not find it when they examined 

 the collection, so that the species stands not so much on the original 

 description as on those of all subsequent authors who have seen in 

 what we now call alienella the true alienella, S.V. 



Hlibner's fig. 41 is not very bad, but his fig. 58 seems to repre- 

 sent a large melanella. It appears that ohscuratus, Hw., and tetrix, 

 Hw., are referable to alienella, and so are histriyella, Dup., and/w72- 

 ginella, Dup., the latter being r«r. h. of Zeller. 



Gymnancycla canella,'^^ . — Simply described in the Vienna Cata- 

 logue, p. 135, as: — "31. Graurothlicher Schabe ohne Einge. T. 

 caiiella."" Fischer v. Eoslerstamm saw a type in the Vienna collection. 

 Zincken was not acquainted with canella, which he describes from 

 Hiibner's fig. 289 under the name of depositella. 



The larva has been described by von Hornig and others feeding 



on Salsola Kali, Atriplex hortensis, and Salicornia lierhacea. Miliiere, 



in his Iconographie, vol. iii, page 158, describes canella as Ancylosis 



cinnamomella, Dup., but on plate 115, fig. 15 to 19, he has JEpisclinia 



(?) cinerella, Dup., and he corrects these mistakes, page 171, saying 



tliat the description applies to Gymnancijcla cinerella, Dup., quoting 



cinerella, Dup., because it is given as a synonym by Wocke ; but 



cinerella, Dup., is quite a different insect belonging to the genus 



Bradyrrlioa, of Zeller.
