 hump. The dorsal and anal regions are a dull yellow, with black 

 waved lines; the sub-dorsal white, with waved black lines. Lower 

 lateral yellow, with waved black lines. All the segments bear 6 or 8

Pale apple-green; head brown; 2d and 3d segment also with brown 

 triangular patch, not united to the brown dorsal patch. On the 2d 

 segment are two raised rough processes, like horns, brown in color. 

 Commencing on the 4th, and continuing to the anal segment, is a 

 brown patch, as in other members of the genus — a mere point on 4, 

 spreading out diagonally on 6 and 7, narrowing on 8, a little wider on 

 9, narrowing again on 10, and wider on 11 and 12. The anal segment 

 is furnished with long filaments alternately brown and green. The 

 lateral green spaces have a number of rather small reddish spots, and 

 on the dorsal brown patch are some small roughened tubercles. 



Length, 1.30 inch. 



Food plant. Willows. 



The younger stages are of a paler color in all parts, without any per^
