•THE GREEN-STRIPED PHYCID WORM. 



[Meroptera pravella Gr.) 



This a common insect on the Willow, occurring at Brunswick, Me., 

 August 90, and through the mouth. It spins a web on the under side 

 of the leaf, and pupates from the loth 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 Phyeis 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. 



Descriptive. — Larva. — Body of the usual form, tapering from near the head to the 

 end. Head of the usual size, not quite so broad as the prothoracic segment : green, 

 slashed vertically and mottled with large and small brown or jet-black spots. Pro- 

 thoracic segment a little swollen ; the shield not striped like the rest of the body. 

 Body with narrow alternating light and dark green stripes; brown along the bade. 

 and inclosing a large round green spot on each segment; the brown portion with 

 three interrupted green lines, one median and two lateral. Piliferous dots minute, 

 not conspicuous. Length, 15 mm . 



Pupa. — Of the usual Phycid shape ; mahogany-brown; end of the terminal abdom- 

 inal spine smooth, shining, convex, and ending in a stout curved lateral spine on 

 each side. Length 10 mm . 



Moth. — Body and fore wings dark gray, w T ith brick-red scales and bands. Palpi ver\ 

 broad, especially the second joint ; dark gray ; vertex of head light gray, with dark 

 scales; antennas blackish. Prothoracic scales and shoulder tippets (patagia) dull 

 brick-red ; middle (disk) of thorax gray. Fore wings dark, dusky gray, with scattered 

 pale gray scales ; base of wingsdull brick-red; a. broad, diffuse hand of the same coloi 

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

 broad, diffuse, dull brick-red band, sending a diffuse longitudinal stripe towards the 

 basal baud ; an incomplete transverse pale gray line, curved out ward in the middle 

 of the wing, borders the inside of the outer reddish band. Costal edge dusky, the 

 reddish bands not reaching it. Friuge of t he same dull slate-color as the hind wings. 

 Expanse of wings. 20 mm . (Identified by Prof. C. II. Fernald.)
