1881.] OF AMURLAND, NORTH CHINA, AND JAPAN. 905 



Erebia MEDUSA, ScliifF. S. V. p. 107 ; Fab. Mant. 40 (1787). 



A single specimen in Dr. Staudinger's collection is all I have seen 

 of this species, which was not found by Radde or Schrenk in Amur- 

 land. This one was collected by Hedemann, probably between 

 Schilka and Blagovetscheask, and agrees with European examples. 



E. PARMENio, Bob. Nouv. Mem. Mosc. ii. p. .306 (1809). 



This species somewhat resembles E. afra, Esp., beneath, but has 

 very differently shaped wings. It was found on the Amur by 

 Maack, aud at Schilka by Radde. 



E. SEDAKOVii (Ev.), Bull. Mosc. 1847, ii. p. 70, t. i. figs. 5, 6. 



E. niphonica, Jans. Cist. Ent. ii. p. 153, t. v. fig. 5 (1877). 



I have compared Japanese specimens from Mr. Jansou with some 

 of E. sedahovii in Dr. Staudinger's collection, and find that they are 

 the same. It occurs on Mount Assamayaina at 7000 feet, and in 

 Nikko. Radde found it on the Apfelgebirge, and Hedemann at 

 Habarofka. It is more nearly allied to E. cethiops, Esp. (Medea), 

 than to E. stygne, with which Janson compares it. 



E. DiscoiDALis, Kirby, Faun. Bor.-Amer. p. 298, t. iii. figs. 2, .3. 



This species, though hardly coming within the limits of my present 

 work, is recorded by JMe'netries as having been found by Maack at 

 Oujan, on the Sea of Ochotsk. I have specimens of it from Mr. H. 

 Strecker, taken at Fort York, British Columbia, and also from Hudson 

 Bay, through Herr Mdschler. They agree very well together, and 

 appear most nearly allied to Erebia glacialis, Esp., though very dif- 

 ferent on the underside. 



E. CYCLOPius, Ev. Bull. Mosc. 1844, iii. p. 590, t. xiv. fig. 3 a, b. 



E. cyclopides (laps, cal.), Brem. Lep. Ost-Sib. p. 19. 



Found at Raddefskaia, Blagovestchensk, Schilka, and elsewhere in 

 Amurland. This, with the next three or four species, form a group 

 of large dark-coloured Erebice peculiar to North-eastern Asia. 



E. TRiSTis, Brem. Bull. Acad. 1861, iii. 



E. wanga, Brem. Lep. Ost-Sib. p. 20, t. ii. fig. 1. 



Bremer changes the name E. tristis, which he had first given to 

 this insect, as it had previously been applied by Ilerrich-Schaffer ; but 

 as his E. tristis (t. 387-390) is a synonym of E. eriphyle, Freyer, 

 it can be retained for the present species. It seems to be common 

 on the Amur, and is found in the Bureija Mountains. 



E. sAXicoLA, Oberthiir, Et. Ent. ii. p. 32, t. iv. fig. 1. 

 Found by Abbe David on the Ourato Mountains, Mongolia. 

 Seems to be allied to E. tristis, but distinct. 



E. ERO, Brem. Lep. Ost-Sib. p. 20, t. xi. fig. 2. 

 Found by Radde on the Apfelgebirge. Allied to E. disci, but 

 differs in having the underside spotted with white.
