GENERAL OBSERVATIONS ON THE GENUS LAVERNA. 



means satisfactorily settled," and I 

 still feel this most painfully. Pro- 

 fessor Frcy had included in hir 

 Monograj)!! of the genus Laverna, 

 in the 14th volume of the " Linncea 

 Entomologica," the delicately pretty 

 Stngmatnphora Dohrnii, Z. I can- 

 not follow him iu this; for though I 

 i-eadily admit it may be difficult to 

 point out any satisfactory character 

 whereby to distinguish rigorously 

 Stagmatojjhora from Laverna, if 

 we remove one species from the 

 former to the latter genus we must 

 necessarily bring others with it, and 

 the tendency in the species of Stag- 

 matophora for the anterior wings to 

 shoAv three pale fascia?, more or less 

 spotted with gold, is a good subsi- 

 diary character possessed by none of 

 the LaverncB. 



Looking only at the head or an- 

 terior wings of a Laverna, we might 

 feel disposed to refer it to the genus 

 Gelechia ; but the very different 

 shape of the posterior wings, the 

 character on which Curtis founded 

 the genus thirty years ago, enal)les 

 us at once to pronounce it no Gele- 

 chia. 



The LarvcB have sixteen legs, and 

 are sometimes rather plump. 



The Pitpa reposes in a rather 

 thin but toujrii cocoon. 



etablies d'une manieresatisfaisante," 

 et mi'me a ce jour j'en snis penible- 

 ment sensilde. Professcur Frey rap- 

 porte ici dans son Monographe du 

 genre I^avcrna dans le quatorzierae 

 volume de la " Linnaea Entomolo- 

 gica," la trcs-jolie Stagmatnphnra 

 Dohrnii, Z. En cela je ue suis pas 

 d'accord avec mon ami; car bien que 

 j'avonc qu'il est assez difficile d'in- 

 diqncr des caracteres par Icsqucls on 

 distingue rigoureusement Stagma- 

 tophora de Leaver na, si nous trans- 

 portons line espece de I'un genre a 

 Tautre, il faut que nous y transpor- 

 tious d'autres, mais la tendance que 

 chez le genre Stagmatophora mon- 

 trent les ailes anterieures de porter 

 trois bandes pales, plus on moins 

 tachees d'or, est un bon caractere 

 snl)sidiaire qui ne se trouve chez 

 aucuue du genre Laverna. 



En regardant seulement la tete et 

 les ailes anterieures de Laverna on 

 pcut etre teiitc de la rapporter au 

 genre Gelechia; mais la coupe si 

 diftcrente des ailes posterieures, 

 caractere sur lequel Curtis a fonde 

 le genre il y a trente ans, nous pcrmet 

 de prononccr de suite qu'elle u'est 

 point line Gelechia. 



Les Che7iilles ont seize pattes ; 

 quclques-unes sont assez dodues. 



La Chrysalide repose dans un 

 cocon ferme, mais assez mince.
