SPRUCE CUDWORM. 33 



•outer fourth of the wing is a conspicuous white Hne, sharply bent out- 

 wards just behind the middle of the wing; beyond the apex of the 

 .angle of the line are several white scales. At the base of the fringe 

 is an oblique line of black scales. The fringe, like the adjoining part 

 •of the wing, is of mixed gray ocherous, with back scales. Hind wings 

 rather broad, pointed, pearly slate gray. Legs, including tarsi, banded 

 with black. Expanse of wings, 13 mm. When rubbed the green color 

 of the fore wings becomes paler, and the three oblique black bands are 

 more distinct." (Packard 1890 p. 851.) 



"Marking same as R. thujaella, except the light shades have an ochr- 

 eous tone rather than fuscous as in R. thujaella. The average size of 

 R. piceaella is about one mm. greater than thujaella.. Otherwise, the 

 two species are very difficult to separate in the imago state. Alar ex- 

 panse 9.5 to 1 1.5 mm." (Kearfott 1903-)

Professor Packard recorded this species on both red spruce 

 and fir from Peak's Island, Casco Bay, j\Iaine, the moth being 

 on the wing at and soon after the middle of July. Larvae were 

 collected by us from Norw^ay spruce on the Campus of the 

 University of Maine, Orono, Alaine, about the middle of May, 

 191 2, associated with the larvae of Epinotia piceafoliana, from 

 which they differed by being a little smaller and with body red- 

 dish with brown head and shield. The moths emerged late in 

 June. Lot 1493.
