270. Ptilophora. plumigera. 



Bombyx plumigera, Esp. Schmett. iii. p. 50. pi. 50. figs. 6, 7 

 (1785); Hiibn. Bomb. pi. 58. fig. 250.

Bombyx palpina, Linn. F. S. p. 305 ; Syst. Nat. xii. p. 828 ; 

 Hiibn. Bomb. pi. 4. fig. 16. 



Ptilodontis grisea, Brem. Lep. Ost-Sib. p. 45, pi, v. fig. 2 (1864). 



A very fine series in Pryer's collection, varying much in the tone 

 of ground-colour. I took two specimens at Nagasaki in June. 



In Japanese examples of this species the fringe of the tooth-like 

 projection on inner margin is but little, if any, darker than the 

 ground-colour of primaries, aud the specimens are, on the whole, 

 much larger than European examples : thus, one female expands 72 

 millim. and a male 58 millim., whilst the smallest of Pryer's 

 measures 52 millim. No. 222, Pryer's Catalogue, is referable to this 

 species.

Two examples ( cJ $ ) in Pryer's collection. Referring to these 

 in his catalogue, Pryer says : " Two specimens only ; one taken by 

 my collector in my presence, on the 18th June, 1876, at Fujisan, at 

 rest in an alder, at an elevation of 5U00 feet ; the other I myself 

 took, at light, on the 19th June, 1881, at Nikko."
