THE CANADIAN ENTOMOLOGIST. 335 



and finer ones i)roceding from faintly-indicated piliferous warts. Head 

 and legs honey-yellow, mottled and streaked with pale brown — the former 

 small — scarcely one-half the diameter of the succeeding segments. Prolegs 

 slender, glassy. 



Pupa inclosed in slight web of very open meshes, resting on a mat of 

 silk on surface of slightly-curled leaf or against the stem, and held in 

 ['osition by a fine thoracic band. It is about S mm. in length ; sparsely 

 iiairy, very pale green, with distinct, dark green dorsal stripe and 

 irregular fainter markings of the same colour and of dull purple or crimson; 



wing-sheaths outlined in dark green. Changes to gray several days 

 before the imago appears. 



The moth expands from i6 to 20 mm. Colours rather dull golden- 



hrown, dark brown and white. These are intermingled in streaks and 

 tiiottlings on the basal two-thirds of the fore wings, the apical area, of clear 

 golden brown, being separated by a distinct triangular line of white, and 

 margined by a fine line of dark brown, succeeded by a white one. The 

 iiind wings are lustrous, golden-brown, except the posterior " feather," 

 which is white with a dark brown triangle near the tip. Abdomen dark 

 brown. Legs white, banded with dark brown. 



As the species is already described, these general characters are given 

 merely to enable any one to whom the original description is not 

 accessible to identify it. 



I am indebted to my friend. Dr. C. H. Fernald, for the determination 

 accompanied by the information that " the specific name is from two 

 'Greek words, the first of which means rose, and the stcond. fingers" which 

 would indicate that the rose-feeding habit of the larva was known to the 

 original describer.
