 PHAUSNA DIMIDIANA, 



BROWN AND ORANGE WING TORTRIX-MOTH. 



SPECIFIC CHARACTER, 



ToitTRix dimidiana: anterior half of the firft wings fufcous, 

 pofterior teftaceous-orange, with four ihort iilvery lines on the exterior 

 margin, 



This little moth, which we are inclined to confider as an uil'dc- 

 fcribed fpecies, is little more than one third the \izc of the preceding 

 infeci. The fufcous, and rich teftaceous-orange of the anterior 

 wings, appear perfectly diitinct arid independent of each other at the 

 bafe and apex of the wing, but unite and blend together about the 

 middle, or a little inclining towards the pofterior end: the whole 

 furface has a nightly gilded, or metallic glofs, 



fig.
