immanata is bright-yellow at first, bu1 afterward dull-green, and never orna- 

 mented with red on the sides. Mr. Hellins also says thai the anal points are 

 acute in C. russata, obtuse in C. immanata. The eggs are laid in August on 

 the leaves of Fragaria vesca, on which the larva feeds." — Newman's British

5 $ and 4 9. — Closely allied in the form of the head and body and stiape 

 of the wings to P. truncata, though the fore wings are less acute, and the outer 

 edge a little less oblique ; the hind wings are much the same. Fore wings 

 blackish-gray at base, with two dark, parallel, toothed lines, the outer forming 

 the outer edge of the space: it has a prominent tooth just below the subcostal, 

 and again just below the median vein (sometimes this tooth is wanting, and 

 the edge goes obliquely from the tooth just below the costa to the inner edge 

 of the wing); beyond is a broad, bright, rusty-yellow band, varying much 

 in width, being sometimes wider than the median blackish band, and some- 

 times only one-third or one-half as wide; the middle third of the wing is 

 occupied with a conspicuous dark band, varying much in width and distinct- 

 ness; it is either dark and uniformly colored, or paler and containing two 

 nearly parallel, black, scalloped lines forming large ringlets behind the median 

 vein; the inner edge of the band is sinuate, curving outward from the 

 costa, and sending a deep sinus outward (away from the base of the 

 wing), but inward toward the center of the band itself (sometimes this 

 indentation is large and broad and the rest of the edge is broadly scal- 

 loped); the outer edge of the band is somewhat as in P. truncata; the 

 edge is usually nearly straight near the costa, but makes a large, broad, 

 rounded angle on the first median space, and then succeeds a deep, acute 

 sinus below the third median vein; a deep sinus, either linear or broad and 

 oblong (as figured by Guenee), is sent in toward the distinct black discal 

 dot; a deep angle, sometimes acute, below the third median vein, from which 

 the edge curves outward. and is twice scalloped; beyond the edge is a rusty- 

 yellow band, scalloped externally, the scallops filled in with deep rusty and 

 black, with two large, rather acute teeth opposite the deep discal sinus in the 

 median band (sometimes the yellow shade is wanting below these scallops
