III. SOUTHERN FORM 



C) Cœnonym-pha tiphon in North-West England. 

 Var. Fhiloxeniis, Esp. 



DESCRIPTION 



Looking over numerous British collections, I hâve seldom failed 

 to discover a séries of philoxeniis from this well-favoured région. 

 Thanks to the generosity of my -friend Mr. C. F. Johnson of 

 Stockport, I too possess a magnihcent séries of the interesting 

 and beautiful Southern Form. The colour of the upper side of 

 both fore and hind wmgs is now a deep warm brown, sometimes 

 almost mahogany; the apical spot on the fore wings, often supple- 

 mented with others towards the médian area, as a rule is sharply 

 defined. The females are generally paler; but in a degree deci- 

 dedly less marked than with those of laid ion. On the hind wings 

 the marginal spots, though varymg in numbers from two or three 

 to as many as six, are much more pronounced, and larger than in 

 examples of the Middle Form; in the female, especially so. 

 While, on the under side of the fore wings the apical spot is deep 

 velvety black ringed with pale yellow, and ocellated, the ante- 

 marginal whitish band conspicuous; and the marginal row of 

 spots, though varying in number, size and intensity, never absent 

 as in some laidion, and almost invanably larger and finer than 

 in tiphon. This is the case in both sexes; the ground colour of the 

 maie rich clear brown; of the female yellow ochre. In both sexes, 

 also, the hind wings are of an altogether warmer brownish-grey, 

 furred at the base, but with a generally more transparent colour 

 than tiphon; and the transverse médian band usually, though not 

 invariably well marked. The fringes on the upper side are often 

 deep and hoary; the strong brown colour of the wing area accen- 

 tuating the contrast.
