224 LLOYDS NATURAL HISTORY. 



Canonympha tiphon, var. rothliebi, Staud., Cat. Lepid. Eur., p. 

 14 (1861). 



This species or variety is darker than C. typhon, and is 

 marked with much larger and more distinct eye-spots, above 

 and below. It is found in July in low swampy places, in the 

 North of England and Wales, and is said to have been met 

 with here and there along the East coast, in Lincolnshire, 

 Norfolk, &c., but has probably long been exterminated in the 

 South by drainage and cultivation ; it may possibly linger in 

 out-of-the-way places like Ashdown Forest, in Sussex, the most 

 southerly locality in England where it has been stated to occur. 



The larva is green, with white lines, and feeds on cotton- 

 grass near the roots in May ; the pupa is green, with dusky 

 stripes on the wing-cases. Several varieties of the Butterfly 

 are represented in the woodcuts.

This is a Butterfly which cannot easily be mistaken by any- 

 one fortunate enough to meet with it. It measures about an 

 inch and a quarter in expanse. The fore-wings are of a reddish- 

 tawny colour, with a broad brown border, and an apical eye 

 beneath ; the hind-wings are brown above and paler beneath,
