GENERAL OBSERVATIONS ON THE GENUS TISCHERIA. 



pennella is only Haworth's translated, 

 and that of Fulvescens is very un- 

 satisfactory. 



In 1838, Zeller, in the " Isis," 

 showed the identity of Reaumur's 

 oak-leaf miner with Hiibner's Co7n- 

 planella, and gave a brief notice of 

 its habits, noticing also the peculiar 

 structure of the antennas. 



In the same year Duponchel figured 

 Complanella and Emyella (Marginca), 

 placing them both in his genus Ela- 

 chhta, but at some distance from 

 each other, not observing their inti- 

 mate relationship. 



In the *' Isis" of 1839, Zeller 

 formed of Complanella the genus 

 Tischeria, remarking that he had 

 seen another species of that genus, 

 and that a third occurred at Vienna. 



In 1840, Ratzeburg, in his " Forst- 

 Insekten," gave the history and 

 figured the mine of Compianella. 



In 1844,Eversmann, in his "Fauna 

 Lepidopterologica Volgo-Uralensis," 

 again described Complanella, but 

 mixed it with other discordant spe- 

 cies in his genus Elachista. 



In 1848, Zeller, in the third volume 

 of the " Linnsea Entomologica," 

 firmly constituted the genus, and 

 described four species (all, indeed, 

 with the exception of the still to be 



notre Complanella^ mais sa descrip- 

 tion de la Rifjipennella n'est qu'une 

 traduction de celle de Haworth, et 

 celle de la Fulvescens est tres-medi- 



ocre. 



En 1838 Zeller dans r"Isis" 

 montra I'identite de la mineuse des 

 feuilles de chene de Reaumur avec 

 \di Coniplanella de Hiihner, donna una 

 courte notice de ces moeurs, et en 

 meme temps tira I'attention a la 

 structure singuliere des antennes. 



La m^me annee Duponchel figura 

 la Complanella, et Y Emyella {Mar- 

 ginea)j les rapportant a son genre 

 Elachista, mais a quelque distance 

 I'une de I'autre, sans remarquer 

 I'affinite intime qui existe entr'elles. 



Dans r^'Isis" de 1839 Zeller 

 forma de la Complayiella le genre 

 Tischeria, remarquant qu'il avait vu 

 une autre espece de ce genre, et 

 qu'une troisieme se trouvait pres de 

 Vienne. 



En 1840 Ratzeburg dans ses 

 '' Forst-Insekten" donna I'histoire et 

 figura la mine de la Complanella. 



En 1844 Eversmann dans sa 

 " Fauna Lepidopterologica Volgo- 

 Uralensis" decrit encore la Coin- 

 planella, mais il la confond avec des 

 especes heterog^nes dans son genre 

 Elachista. 



En 1848 Zeller dans le Seme 

 volume de la *' Linnasa Entomo- 

 logica" constitua solidement le genre 

 Tischeria et decrivit quatre especes 

 (c'est-a-dire, sauf la Dodoncea qui
