Boily pretty uniformly fusco-lutODUs, lliu higli warls black, the liairs fully as long as 

 tlie -widtli of the boily, pale Inteous, slightly infuseated next tlie very base, and with 

 distant spicules. Length of l)ody, 2.'> nun. ; of liairs of body, .00 mm. ; -width of head. 

 .;!3 mm. 



Second stage. Head black -with black hairs. Boily l)r(mn-green, the tubercles and 

 spines black; beset with many short, divergent, ))lack bristles. Length, 2.8 mm. 

 (After Edwards.) 



Tliird stage. Head as before. Body gray-black with a green tint over the dorsal 

 surface; beneath pale green; tubercles pale yellow, the spines and their bristles black. 

 Length, .4 ram. (After Edwards.) 



Fourth stage. Head reddish yelloAV, more yelloAv behind. Body gray mottled Avith 

 l)lack; a double dorsal stripe of gray ; tnljercles supporting black spines dull yellow in 

 the laterostigmatal and infrastigmatal series, black on the inner and yellow on the 

 outer side of those of the laterodorsal series. Length, 8 mm. (After Edwards.) 



Fifth stage. Much as in the preceding stage. Length, 12.7 mm. (After Edwards.) 



Last stage. Head dark, becoming pale testaceous behind, the front with scattered 

 hairs. Body dark, velvety purple above, scarcely paler beneath. Basal half of spines 

 pale livid, the spinules nearly half as long as the spines themselves; small papillae- 

 bearing bristles are scattered over the body, with a row of them above the prolegs. 

 (After Packard.) A fuller description is given by EdAvards (Can. ent. , xx : 2). 



Chrysalis (84: fi). Chestnut broAvn, mottled and irrorate Avith black, <the Avings 

 black at tlie base ; the whole surface of the body Avrinkled ; the spiracles black and 

 conspicuous. (After Packard.) Packard makes no mention of a laterodorsal tubercle 

 on the mesothorax. The draAving by Mrs. Peart (pi. 84, tig. fi) made for Mr. W. H. 

 EdAvards and Avhich he alloAved me to copy, represents the Avings as lighter in color 

 than the rest of the body, broAvnish luteous rather than chestnut broAvn, infuseated 

 only at base, and the rest of the body dark broAvn, the Avhole Avrinkled and black at 

 the Avrinkles. Length, 20.5 mm. 



There is no need of confounding this species Avith either of the preced- 

 ing ; it is smaller than they, duller in tint above, has a blackish border to 

 all the Avings in both sexes, and a more continuous mesial band on the 

 upper surface of the hind Avings ; the darker colors of the under surface of 

 the hind Avings are deeper in hue than in either of them, Avhile the buff 

 belt is wider than that of aphrodite and narroAA^er than that of cybele ; the 

 buff scales on the basal half of the Aving also assume more importance 

 than in the other species : finally the costal border of the fore Avings does 

 not appear to be quite so much arched. 



Synonymy. It is possible, perhaps even probable, that this species is 

 the true Pap. aphrodite of Fabricius, but as it is quite impossible to be 

 certain of it, the names ought to stand as given by ]Mr. W. H. Edwards, 

 who first clearly distinguished the species in this difiUcult group. The 

 species were still confounded in the British jNIuseum after the publication 

 of Butler's Fabrician butterflies, as I myself saAv, and notwithstanding 

 Butler's remarks on p. 109 of that Avork. 



Distribution (21 : 7). This member of the Canadian fauna is abundant 

 throughout all the cooler parts of Canada, and in the east is very nearly 

 limited southAvardly by the annual isotherm of 45°, only surpassing it 

 in elevated regions and along mountain chains. XorthAvard it appears 

 rarely to encroach upon the Hudsonian fauna, but specimens are reported
