GENERAL OBSERVATIONS ON THE GENUS SWAM.MEKDAMIA. 



l)y themselves, antl establishes on 

 linn characters the genus Sivammer- 

 damia, describing live British spe- 

 cies. Frey confu-ms the ncAv genus 

 in his "Tineen und Pterophoreu dcr 

 Schweiz," Avherc he has four Swiss 

 species. Herrich-Hchiiffer enumer- 

 ates nine species in the fifth volume 

 of his " Schmetterliuge von Europa," 

 but the first of these, Simplicclla, is 

 the nnicolorous variety of Prajjs 

 Curtisclliis, already spoken of in 

 this volume, and the eighth species, 

 EgrcgicUa, appears, after a careful 

 study of the insect in all its stages, 

 better located in the genus Hypono- 

 meuta. The insect which he con- 

 sidered to be the female i)i Alpicella 

 is, as I have already pointed out 

 (Trans. Ent. Soc. Loudon, 1868, 

 p. 137), generically distinct, being 

 Zelleria Saxifragce. 



Tengstrom had described tw^o 

 Finland species in his " Bidrag till 

 Finlands Fjiiril Fauna," in section D. 

 of his genus Tinea. One of these, 

 Nubecdlclla, is still far from being 

 satisfactorily made out ; but the 

 other, Conspersella, has been reared 

 from the larvae by my friend Baron 

 von Nolcken, who kindly gave me a 

 notice of its habits, which appeared 

 in the " Entomologist's Annual" for 

 1868, p. 155. 



sectes par eux-mOmcs, ct constituc 

 sur dcs caracteres fixes le genre 

 Sicammcrdamia, dont il decrit cinq 

 especes Britauniques. Frey dans 

 ses " Tineen und Pterophoreu der 

 Schweiz" a coufirme ce nouveau 

 genre, et decrit quatre especes 

 Suisses. Herrich-Schilffer rapporte 

 neuf especes a ce genre, dans le 

 cinquieme volume de ses " Schmet- 

 terliuge von Europa," mais la pre- 

 miere, la Simplicella, est la variete 

 uuicolore du Prajjs Curtisellus, dont 

 nous avons dujii parle dans ce volume, 

 et la liuitieme espece, VEgregicUa, 

 parait, lorsqu'on I'etudie avec soin 

 dans tons ses etats, se rapporter 

 mieux au genre Ilyponomcuta. 

 L'insecte qu'il a rapporte comme 

 femelle a la Sicammerdamia alpi- 

 cella est generiquement distincte, 

 comme je I'ai deja indique (Trans. 

 Ent. Soc. Loud. 1868, p. 137), c'est 

 la Zelleria Saxifragce. 



Tengstrom a decrit deux especes 

 de Finlande dans son " Bidrag till 

 Finlands Fjiiril Fauna," dans la 

 section D. de son genre Tinea. 

 Une de ces especes, la Nuhecidclla, 

 n'est pas bien connue meme a ce 

 jour ; mais I'autre, la Conspersella, a 

 etc elevee de la chenille par mon ami 

 Baron von Nolcken, qui a eu la com- 

 plaisance de me donner une petite 

 note sur ses mocurs, que j'ai publico 

 dans r " Entomologist's Annual" pour 

 1868, a p. 155.
