<} u |il P. Liriodendronella. Fore-wings silvery-white, the pos-

 golden streak along the middle of the Aving above the fold, 

 arising at its base. About the middle of the costa is a pale 

 golden, oblique costal streak black-margined on both sides, 

 which coalesces with the posterior end of the median streak. 

 The costal cilia silvery, containing three diverging black 

 streaks. The apical spot black, with a silvery scale or two 

 before and behind it, and at the extreme apex, tAvo black 

 lines in the cilia, diverging from the apical spot. In the 

 cilia of the hinder margin is a black, curved line, and at the 

 beginning of the cilia of the hinder margin is a dorsal silvery 

 spot. Hind-Avings silvery -gray ; cilia the same. 



Antennas, head, labial palpi silvery-white. 



The larva mines the small terminal leaves of the branches
