GENERAL OBSERVATIONS ON THE GENUS TISCHERIA. 



defined Dodoncea, which are yet 

 known). 



In 1854, Stainton, in his vohime 

 of the " Insecta Britannica," de- 

 scribed the genus and the two species 

 Coniplanella and Marginea, mention- 

 incp the habit of the larva of the 

 latter. 



In 1855, Herrich-Schaffer, in the 

 fifth volume of his " Schmetterlinge 

 von Europa," repeated the four spe- 

 cies given by Zeller in 1848, but no 

 new ones were added. 



The following year Frey, in his 

 " Tineen und Pterophoren der 

 Schweiz," introduces the three Swiss 

 species of the genus, and describes 

 the larva of Angusticollella. 



The only species added to the 

 genus since 1848 is Tischeria Do- 

 doncea, which was naturally easily 

 overlooked as a small Complanella, 

 and it was not till attention was 

 given to the mine of the larva that 

 its specific distinctness was ascer- 

 tained. I am indebted to my very 

 kind friend Senator von -Hey den for 

 calling my attention to it. 



reste encore a definir, toutes celles 

 que nous connaissons aujourd'hui). 



En 1854 Stainton dans son volume 

 de r*' Insecta Britannica" precisa 

 le genre et les deux especes Coni- 

 planella et Marginea, et donna les 

 moeurs de la chenille de la derniere. 



En 1855 Herrich-SchafFer dans le 

 5eme volume de ses " Schmetterlinge 

 von Europa" repeta les quatre es- 

 peces donnees par Zeller en 1848, 

 sans ajouter aucune espece nouvelle. 



L'annee suiyante Frey dans ses 

 '' Tineen und Pterophoren der 

 Schweiz" exposa les trois especes 

 Suisses de ce genre, et decrivit la 

 chenille de V Angusticollella. 



La seule espece nouvelle depuis 

 1848, est la Tischeria Dodoncea, qui, 

 etant facile a meconnaitre, a ete prise 

 pour une petite Complanella, jusqu'a 

 ce qu'on ait fait attention a la mine 

 de la chenille, chose necessaire pour 

 etablir la distinction specifique. Mon 

 obligeant ami le Senateur Von Hey- 

 den a eu la bonte de fixer mon at- 

 tention sur cette espece.
