pale waved lateral line close to a broad yellowish white stigmatal one ; venter 
dark, shaded with pale subventral and broad medio-ventral bands. Feet pale ; 
tubercles concolorous, set® short, dark ; no shields. 
Stage V. Head bilobed, flattish before, oblique ; light green, faintly reticu- 
late, ocelli in part black ; width 2.6 mm. Body cylindrical, moderate, smooth, 
light green, the color of the young needles, slightly white shaded, leaving a dor-

white, moderate, equal ; faint traces of a waved lateral line ; subventral and 
geminate ventral line yellowish, very faint. Tubercles obsolete, set® dark, fine ;

The larv®, when mature, became reddish and entered the ground to pupate. 
F.ggs June 4, mature larv® July 9; single brooded, hibernation in the pupa. 
The larv® fed on the needles of spruce, eating only the pale ones of the same 
year’s growth, which they closely matched in color. Larv® from Kaslo, British 
Columbia. 
LXI. Retrophora conva/laria Guemie. This species is not improbably the 
same as the Furopean 7 ?iunita/a Hiibner. My specimens agree with what Guenee 
says of his convallaria, and I have no doubt that it was this form he had before 
him. 
Egg. Rounded elliptical, no flattening, truncation and depression indica- 
ted, but rounded ; smooth, shining pale yellow, reticulations barely indicated as 
shadowy lines, regularly reticulate; very shining; size .6X.5.X.4 mm.
