So far, then, as at présent ascertained, it would appear as though 

 upon the continent Cœnonympha tiphon, with its varieties, 

 were confined between 4° and 45" Long. E. (*), and 70° and 44° 

 Lat. N., reaching its southernmost point in Bosnia, and Herce- 

 govina (Bosnisch-Brod, and Jacje. Mrs. M. de la Bêche-Nicholl). 



And hère, perhaps, I may be allowed to point out that my dear 

 friend the late Rev. Dr. H. C. Lang, in his pioneer work, " The 

 ButterfLies oj Europe " (quoted by M. Oberthùr, loc. cit.), 

 working upon too limited material, diagnosed the British and Irish 

 forms incorrectly. He is quite right to cite laidion, Bkh., as an 

 aberrant f orm in Ireland, though he uses the word " variety '' ; but 

 quite wrong in his statement that it occurs " as a variety " in 

 Scotland if he means that throughout Scotland it is the dominant 

 form. While the statement (p. 312) that phïloxemis, Esp., occurs 

 " principally in Durham, Cumberland, and Yorkshire " is as sin- 

 gularly wide of the mark as that it constitutes a separate species. 

 I hâve shown that in not one of thèse three counties is philoxenus 

 the dominant form; on the contrary, that it occurs rarely in the 

 last two, and then usually in a transitional form. Why, also, he 

 should suppose that philoxenus is limited to Britain I cannot say, 

 since Esper made his original description of this variety from 

 north-German examples, and this was confirmed by his chemist 

 friend of Neustadt-on-the-Aisch. 



Fritz Rùhl {Die palaearktischevi Gross-Schmcilerliiige, Band I, 

 p. 621) at ail events quotes several localities for philoxenus in the 

 " Esper country ", as well as the Bùhlerthal in Baden, and, furthcr 

 away still, Lemberg in Galicia; though I cannot say his description 

 is convincing that the German and the English philoxenus are
