Cryptollahes histriga, Hw. — The larva of this species has been 

 described by J. von Hornig and Anton Gartner as feeding on Alnus 

 glutinosa, but Buckler described it as feeding on oak. 



M. Milliere has re-described histrif/a under the name of Epliestia 

 Jugdunella. 



Nyctegretis achatinella, Hb. — The larva was discovered by Herr 

 Sorhagen, who describes it in the Berliner ent. Zeitung, vol. xxvi, 

 p. 156. It feeds on Sedum sexangulare, forming a thick white gallery 

 which extends from the lower part of the flowering stems to the roots ; 

 is full-fed towards the middle of June. 



Myelois crihrmn, S.V. — This common species has borne several 

 names, and that of crihrum is wrongly applied, for in the Catalogue of 

 Schiffermiiller and Denis the insect bearing that name is placed among 

 the '' Noctuce,'' between Setina roscida and Deiopeia pidcheUa, proving 

 that the authors had only in mind Emydia crihrum, Lin., and not a 

 Phycid (or Tinea, according to the early writers). Thus we find in 

 the Vienna Catalogue, page 68 : — " 8. Weisse schwarzpunktirte Eule, 

 N. crihrum, Linn. ;" the quotation of the Linnsean name and the place 

 assigned to the insect showing that the authors intended the well- 

 known Bomhycc, and not a new species, so that even if in the collection 

 there were specimens of the Phycid the name could not stand. The 

 species was afterwards figured and described by Hiibner, in his 

 Beytrage, vol. i (pi. 3, fig. ss. 24), under the name of Tinea crihrumella, 

 but as this is evidently the same as crihrum, with the ending of " ella, 

 I consider it must be put aside for the same reason. 



The insect was next published and described as Tmea crihrella by 

 Hiibner, fig. 67, page 36, and this name should be retained; sub- 

 sequently, in his Catalogue, Hiibner changed the name to medullalis, 

 in order to avoid confusion with Emydia crihrum, but this alteration 

 was not needed. The larva feeds in the heads of thistles, and hiber- 

 nates in the dried stems, but sometimes (in the south of Prance), it 

 changes to a pupa in July, and the moth appears towards the end of 

 the same month and beginning of August. Treitschke originated the 

 error in the life-history of the insect that the ova are deposited on 

 the stems, and that the larv« feed only in the interior of the latter. 



Myelois suavella, Zk.— The larva is well-known, feeding on sloe 

 and hawthorn. 



Myelois adveneUa, Zk.— The larva, feeding on hawthorn and Sor- 

 hus aucuparia, has been described several times.
