THE GrREEN- STRIPED PHYCID WORM. 
(. Meroptera pravella Gr.) 
This a common insect on the Willow, occurring at Brunswick, Me., 
August 20, and through the month. It spins a web on the under side 
of the leaf, and pupates from the 15th to 20th of September, the moth 
in confinement appearing (in the breeding cage at Providence) the end 
of May (the25th-31st). The caterpillar, which is longitudinally striped 
with light and dark green with black slashes on each side of the head, 
varies somewhat; in some there are only four slashes on the head, with 
no other markings. The moth differs from Phycis rubrifasciella on the 
Hickory in having no cross-band of raised scales, while the insect is 
much darker, and the palpi are twice as broad.

crosses the basal fourth of the wing ; on the outer fourth of the wings is a similar
