GENERAL OBSERVATIOXS OX THE GENUS LAVERNA. 



and Langiella in his genus Ela- 

 chista. He has also one other i.ot 

 known to Iliibner, Sturnipctuwlla, 

 iu his genus Ornix, which is iden- 

 tical withllaworth's SubbistrigeUa ; 

 in his supplementary volume he de- 

 scribes an (Ecophora epilobiclla, 

 identical with the Fnlvcscois of 

 Haworth and the Epilobiella of 

 Schrank, Ijut not of Komer. 



Stephens in his Illustrations has 

 four species o? Laverna, all of which 

 he placed in his genus Anacnmpsis : 

 Lacteella, p. 210, Decorella and 

 Atra, p. 21 3, and Fulvescens, p. 215; 

 the two first of these were then new, 

 and the last-named he described a 

 a second time under the name of 

 Clcodora nebulcUa, p. 221. 



Duponchel iu the 11th volume of 

 his " Lepidopteres de France" has 

 only one good figure we can refer to 

 this genus, that o{ Alttcifa Ilellcr- 

 clla, pi. 293, f. 11, which is iden- 

 tical with var. y. of the Atra of 

 Haworth. 



The year 1839 was an eventful 

 year in the history of the study of 

 tliis genus ; in that year Curtis 

 published his definition of the genus 

 Lavcnia, pointing out that it differed 

 essentially from Anacampsis in the 

 very narrow and lanceolate posterior 

 wings, and gave a most exquisite 

 figure of Lavcrna ochraceclla. 

 Curtis referred, however, only four 

 species to the genus, and of these 

 only two are veritable Larernce: 

 Ochraceclla and Atra; his Sarci- 

 tella is what we now know as 

 Endrosis fcncstrclla, and his Mar- 



vella dans cclui Ol (Ecophora, et 

 la LatigicUa dans celui d'Ela- 

 chista. II a de plus decrit ime 

 espc'ce que Hiibner n'avait pas con- 

 nue, la Sturnipennclla, dans son 

 genre Ornix, espece qui est la meme 

 quo la SubbistrigeUa de Haworth ; 

 dans son volume supplementaire 

 Treitschke decrit une Q^cophora 

 epilobiclla, identique avcc la Ful- 

 vescens de Haworth et V Epilobiella 

 de Schrank, mais qui u'est pas 

 VEpilobiella de Rijmer. 



Stephens dans ses "Illustrations" 

 a quatre especes de Lavcrna, toutes 

 placees dans son genre Anacampsis: 

 la Lacteella, p. 210, \a, Decorella et 

 VAtra, p. 213, et la Fulvescens, p. 

 215; dont les deux premieres etaient 

 alors nouvelles. II decrit la deruiere 

 espece une seconde fois sous le nom 

 de Clcodora ncbnlella, p. 221. 



Duponchel dans le onzieme volume 

 de ses "Lepidopteres de France" 

 n'a qu'uue seule bonne figure que 

 nous ^missions rapporter a ce genre, 

 celle de VAlucita Hellerella, pi. 293, 

 f. ] 1, qui est la meme que la variete 

 y. de VAtra de Haworth. 



L'annee 1839 fut feconde en evene- 

 ments dans I'histoire de I'etude de 

 ce genre — ce fut alors que Curtis 

 publia la definition du genre, indi- 

 quant comment il differait csscn- 

 tiellement du gcure Anacampsis dans 

 la coupe des ailes poterieures, si 

 etroites et si lanceolees, et il figura 

 a merveille la Lavcrna ochraceclla. 

 Mais cependant Curtis n'a rapporte 

 que quatre especes a ce genre, dont 

 il n'y a que deux qui sont des veri- 

 tables Lavcrna: V Ochraceclla et 

 VAtra ; sa Sarcitclla est I'espece 

 que iious appelons anjourd'hui En-
