We pollefs two fpecles of the Green Silver Line; one'Phalaena 

 Prafinana, of Linnaeus j the fecond unknown to that author; but fince 

 defcribed in the Species Infeaorum of Fabricius. Thofe two fpecies 

 nearly refemble each other, are both taken from the Oak, and are 

 diftinguiflied only in fome few particulars, the Scarce Silver Line has 

 its Superior Wings of a plain pea-green, with tv/o ftripeS of feint 

 yellow, the Body and inferior Wings are of an immaculate white. 

 But the Common Silver Line is more variegated in its colour, having 

 a dafh of a paler hue between each Silver Line, and an orange or 

 crimfon border. The Scarce Silver Line is taken in July, in woods. 



Note, Fabricius appears to have changed the name of this Infeil: in 

 his Spec Inf. for in the Syjiem Entom. he calls the common Silver 

 Line Prafmana, the fame as Linnaeus does, which in the Spec he has 

 altered to Fagana.
