This is one of the most common of our gcometrid moths, and may be 

 recognized by its uniformly pale ochreous hue, t lie three black costal spots, 

 and the absence of any other markings. 



Larva. — "Cylindrical. Head medium sized, rather flat in front, pale 

 green, slightly bilobed, without any markings; mandibles tipped with black 

 (labium a little paler than the other parts of the head) — a few very fine small 

 hairs visible only with a magnifying-glass. Body bluish-green, with thickly- 

 set longitudinal stripes of whitish and yellowish. A double whitish dorsal 

 line with a yellowish-white line rather more prominent on each side of it 

 (these are not unbroken, but formed of a succession of yellowish short lines 

 and dots). Below this on each side are two or three imperfect white lines 

 made up of short broken streaks, much fainter than those above. The 

 spaces between the segments are yellowish ; the skin is much wrinkled and 

 folded. The under side is green, with tinge of yellowish between the seg- 

 ments ; abdominal legs yellowish-green and faintly tipped with brown. 

 Chrysalis, June 19. It feeds on the maple." (From notes received from 

 Mr. W. Saunders, of London, Canada.)
