GENERAL OBSERVATIONS ON THE GENUS ELACHISTA. 



looking Fuscochreella and Muhligiella, 

 being new. One feels strongly 

 tempted to doubt vvhetber these two 

 last really belong to the genus, but 

 they are not more discordant than 

 Quadre/la, and the neuration of the 

 wings of Muhligitlla, investigated by 

 Fre}', and o^ Quadrtlla, examined by 

 myself, confirms their position in the 

 genus Elachhla. 



Schrank, Curtis, Zetterstedt and 

 Eversmann make no allusion to any 

 one of the genus, unless indeed the 

 latter author's Bifascidla be meant 

 for one, which appears very proble- 

 matical. 



Thus, prior to 1817, not more than 

 fifteen species seem to have been 

 firmly established ; the subsequent 

 ten years have added fifty-seven to 

 those fifteen. It is to be hoped that 

 this volume will not be without influ- 

 ence on the further investigation of 

 the genus, though we are not so san- 

 guine as to expect another increase 

 of nearly 400 per cent, in the next 

 ten years. 



et les bizarres Fuscochreella et Aliih- 

 ligklla, sont nouvelles. On est bien 

 tente de douter, si ces deux der- 

 ni^res appartiennent reellement a ce 

 genre, mais elles ne sont ccpendant 

 plus singulieres que la Quadrellat et 

 la nervulation des ailes de Muhligiella 

 etudiee par Frey, et de la Quadrclla 

 etudiee par moi-meme, tend a con- 

 firmer la position de ces especes dans 

 le genre ElachUta. 



Schrank, Curtis, Zetterstedt et 

 Eversmann ne font aucune allusion 

 aux especes de ce genre, a moins que 

 la Bifascidla de Eversmann n'en 

 soit une, ce qui parait etre peu pro- 

 bable. 



Ainsi avant I'annee 1847 on ne 

 parait pas avoir bien connu plus de 

 quinze especes; les dix dernieres 

 annees y ont ajoute 57 d'autres. On 

 doit esperer que le present volume 

 aidera a avancer la connaissance de 

 ce genre d'insectes ; il serait cepen- 

 dant temeraire de penser que la pro- 

 chaine disaine d'annees quadruplera 

 encore le norabre actuel des especes 

 connues.
