SATYRID/E. 221 



white centres ; cilia white with brown dashes. Underside 

 richly clouded with dark brown ; hind wings very dark, but 

 with an abbreviated white fascia ; spots as on the upper side. 

 Described and figured by the late J. F. Stephens in the 

 Illustrations of British Entomologf/ (1828), from specimens in 

 his own collection, of which he says : "The only indigenous 

 specimens which have come to my knowledge were captured 

 in the Isle of Arran, I believe, by Sir Patrick Walker and 

 A. MacLeay, Esq. ; but I am not aware of the true locality 

 or of the period of the year, which is probably about July or 

 August." He then proceeds to show accurately, how it differs 

 from the female of E. Blandina, and most conclusively proves 

 that, as might otherwise have been suspected, there had 

 been no confusion with regard to this species. Neverthe- 

 less it seems hard to avoid the suspicion that a substitution 

 or confusion of s2Jccimcns had taken place, seeing that all 

 attempts to re-discover the species, in the siibsequent sixty 

 years, have failed. Richard Weaver wrote in 1857: "I 

 passed to the Isle of Arran in the hope of obtaining Ligca, 

 I had seen two specimens in the cabinet of the late Mr. 

 Stephens which were captured by the late Sir Patrick 

 Walker on the moors at the back of Brodick Castle, when 

 out one day grouse shooting. I was informed by Mr. 

 Stephens that he had the statement from Sir Patrick himself. 

 I tried the locality three seasons without finding the insect, 

 still I do not despair. I found Blandina in profusion." 

 Many others have since visited Arran with the same hope — 

 and the same result. The hope of the re-discovery of this 

 species was encouraged and stimulated by the obvious fact 

 that the district is most suitable for such a species, and that 

 of about thirty European species of Erebia, it seemed im- 

 probable that we should possess not more than two ! Mr. 

 Stephens's specimens are now in the British Museum and 

 suspicion of their foreign origin has been most strongly con- 

 firmed by the discovery, by Mr. A. G. Butler, that while the 

 female is certainly E. Ligea, the male is as certainly E. Euryalc,
