as in P. guttata. All the specimens I have seen are from Japan, 

 where it seems common. 



Pamphil.v jansonis, Butl. Cist. Ent. ii. p. 284 (18/8). 



Mr. Butler says this insect is widely distinct from the last ; but 

 the type in the British Museum seems very similar to it, though in 

 some specimens the spots on the hind wings are partly obsolete,

The forms of H. sylvanus found in Cliina, Japan, and Amurland 

 are usually larger than the European ones ; but in Dr. Staudinger's 

 opinion we are not justified by our present knowledge in keeping 

 them separate. Specimens of H. sylvanus from Astrabad in his 

 collection agree with Menetries's figure of //. subhyalitia and 

 with specimens I possess from Japan and China, also with forms of 

 H. sylva7ius from Baranofsky and Raddefskaia. 



H. venata, Brem., as figured, seems to be an aberration of H. syl- 

 vanus; but may be a distinct species. Dr. Staudinger has a speci- 

 men quite like the figure but smaller, collected by Hedemann in 

 Amurland. 



I have seen the type of H. herculea, which is, I think, a Japanese 

 form of H. sylvanus. 



H. sylvatica, Brem. Lep. Ost-Sib. p. 34, t. iii. fig. 10. 



Found in various parts of Amurland and at Tokio. 



It is a small species allied to H. actceon of Europe, but with paler 

 disks margined with brown and the underside marked with con- 

 spicuous dark veins. 



Very near it is 



H. LEONiNA, Butl. Cist. Ent. ii. p. 286 (18/8). 



According to Mr. Butler, this is " markedly distinct ;" but, except 

 that it is brighter in colour and less overlaid with brown, I do not 

 see much to distinguish it. 



H. OCHRACEA, Brem. Lep. Ost-Sib. p. 33, t. i. fig. 11. 

 Allied to the last two, but distinct. I have it from Japan, 

 Askold, and Raddefskaia. Near it is
