ELACHISTA GLEICHENELLA. [PlATeVI. FiG. 2. 



All descriptions are liable, in the 

 lapse of time, to labour under the 

 difficulty of not sufficiently distin- 

 guishing a species from others which 

 were unknown at the time ; but 

 surely it is wiser to make allowances 

 for the imperfections of the times 

 than ruthlessly to throw down all the 

 names of the fathers of Entomology, 

 simply because their descriptions are 

 not such as would satisfy us now; 

 how do we know that the descrip- 

 tions we are writing will be any more 

 satisfactory a hundred years hence ? 



vent quelque temps pecher par de- 

 faut de precision, et etre incompletes 

 quant a la distinction de quelques 

 autres especes qui n'etaient pas 

 connues encore, mais assurement il 

 serait plus sage d'avoir egard aux 

 imperfections des temps, que de re- 

 jeter impitoyablement tous les noms 

 sanciionnes par les peres de I'Ento- 

 mologie, seulement a cause qu'actu- 

 ellement elles ne semblent pas assez 

 precisees. Mais comment savons 

 nous, si nos descriptions paraitront 

 plus satisfaisantes apres cent ans?
