I04 LEPIDOPTEROLOGIE COMPARÉE 



Corzemalzie, Whauphill takes it not infrequently. He has been 

 good enough to allôw me to examine his séries. Inclined to vary 

 in depth of colour from rich brown to pale tawny, the arrangement 

 and frequency of the under side ocellations of the hind wing 

 confirm them as examples of the Middle Form, though a few of 

 them are decidedly on the way to ■philoxemts. 



In the adjoining county, Dumfriesshire, tiphon is reported from 

 Cloak Moss, Dalbeattie, and no doubt occurs thence to the Cheviots. 

 But from the Clyde south eastwards it becomes rarer and rarer 

 until, on the authority of Mr. W. Renton, who some years ago 

 made a conscientious study of the lepidoptera of his district, we 

 hear of it only in one Roxburghshire locality, Reidfordgreen 

 Moss, near Hawick {Entomologist, Vol. XXXVI, p. 131). 



Of course, it does not follow that tifhon is absent generally 

 from the " Lowlands ". This part of Scotland has been less 

 worked than many of the remoter highland local ities, while we 

 know that immediately across the Border, tiphon re-asserts itself, 

 drawing towards the North Sea as the industrial area contracts. 

 The seaward Scotch counties in this direction, however, are less 

 adapted to sustain the species; the land is grazed or closely culti- 

 vated; and the mosses, where such existed in times past, hâve 

 been converted to agricultural purposes. None the less, across 

 the Forlh, and the dividing line eastward between the Northern 

 and the Middle Form, there should be occasional sequestered spots 

 where tiphon has not been improved off the face of the earth. 

 Dr. A. F. Rosa of Edinburgh tells me that it used to occur on a 

 heath about nine miles from the city. It is reported also from 

 the Pentland Hills, and hereabouts Mr. K. J. Morton found it in 

 an isolated Peebleshire bog between West Linton and Dolphinton. 

 Mr. E. W. Carlier also took it on Balerno Bog, to the south-east 

 of Edinburg, on July 23rd., 1885; and on the Peebleshire border, 

 rather more than twenty years previously, the last apparently of 

 the race hereabouts was captured on a moor south of Leadburn.
