Phalena arcuaiia is an infeB of uncommon beauty. The general 

 colour of the anterior Mings is yellowiih brown, or teftaceous, varied 

 with darker towards the exterior margin, and tranfverfely ftriped with 

 filvery: there are alio at the bafe two remarkable arched, or m- 

 curvated filvery lines. In the diik, a little inclining towards the inner 

 margin, is a broad fpace, of a pale yellow colour, in the center 

 of which is a black fpot, enriched with three filvery dots. The lower 

 wings are obfeure. 



This infecl is found on the nut tree in its perfect ftate : its trans- 

 formations are not clearly known.

 PHAUENA DIMIDIANA, 



BROWN AND ORANGE WING TORTRIX-MOTH, 



SPECIFIC CHARACTER, 



Tortrix dimidiana: anterior half of the firii wings fufcous, 

 pofterior teftaceous-orange, with four fhort filvery lines on the exterior 



margin. 



This little moth, which we are inclined to confider as an unde- 

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

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

 wings, appear perfectly diftinci and 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 

 Surface has a ilightly gilded, or metallic glofs.
