906 MR. H. J. ELWES ON THE BUTTEnFLlES [NoV. 15, 



Erebia edda, Men. Micld. Reise, t. Hi. f. 2 (1851). 

 Found at Schilka by Radde. Of the same group as E. tristis, 

 to which it is allied ; but the ocelli differ in colour. 



E. AJANENsis, Men. 



E. ligea, var. ajanensis, Men. Cat. Mus. Petr. 104. 



E. eumonia, Men. Schrenk's Reise, p. 34, t. iii. fig. 4. 



Of this species, which was taken at Hadshi, on the coast of 

 Mantchuria, in lat. 49°, and at Nikolaiefsk, I have seen no specimens ; 

 but, from the plate, it is evidently nearly allied to E. ligea. 



E. EMBLA, Thunb. Diss. Ent. ii. p. 38, t. viii. fig. 8 (1791). 

 Does not occur in Araurland, but was found on the Sea of Ochotsk 

 by Maack. 



(Eneis( = Chionobas) sculda (Ev.), Bull. Mosc. 1851, i. p. 612. 



Found by Hedemann on the Upper Amur, but not included in 

 Mene'tries's or Bremer's works. A species, or perhaps a variety of 

 this, is in Dr. Staudinger's collection, collected by Hedemann. 



CE. jutta, Hb. t. 914-5. 



Found by Maack, according to Bremer, on the south side of the 

 Amur, but not seen by Dr. Staudinger. 



CE. URDA (Ev.). 



Hipparchia iirda, Ev. Bull. Mosc. 1847, ii. p. 69, t. ii. figs. 1-4. 

 Chionobas nanna, Men. Schrenk's Reise, p. 38, t. iii. fig. 5. 

 Seems not uncommon at Blagovcstchensk, Raddefskaia, and else- 

 where in Amurland. 



(E. MONGOLicA, Oberthiir, Et. Ent, ii. p. 31, t. iv. fig. 6 (1876). 

 Found in the mountains of Eastern Mongolia by Abbe David. 

 Seems very nearly allied to CE. tarpeia. 



Satyrus dryas. Scop. Ent. Carn. p. 153 (1763). 



8. bipunctatus, Motsch. Et. Ent. ix. p. 29. 



Var. sibirica, Stdgr. Cat. p. 29. 



Found in the Bureija Mountains, and common on the coast-regiou 

 of Amurland; also common in Japan. The Japanese form agrees 

 very fairly with European examples, though generally larger and 

 more strongly marked. 



The form found at Askold is the var. sibirica, Stdgr., and differs, 

 as a rule, in having the markings of the underside almost obsolete. 



The form described as S. bipunctatus by Motschulsky I presume 

 to be merely an aberration of »S'. dryas, with two spots on the hind 

 wings. I have seen one or two specimens which have them. 



Pararge achine. Scop, Ent. Carn. p. 156 (1763). 



P. achinoides, Butl. Cist. Ent. ii. p. 283 (1877). 



Found at Baranofsky, Raddefskaia, and Askold, also in Japan.
