RHOPALOCERA AT BARCELONA, ETC. 299 



consideration of the arguments in favour of maturity set out 

 in our previous communication have confirmed our impression 

 that we are dealing with a mature form. The species has been 

 unusually abundant with us this year, and we have paid special 

 attention to the immature coloration, with the result that we 

 are satisfied that at no stage of its colour-development does the 

 typical form correspond with the dark form. The fact that the 

 latter has occurred in three successive years encourages the 

 belief that it is also permanent, and to this form we now propose to 

 give the varietal name of infuscans. 



During the present season, also, the orange variety of the 

 female (rufescens, Steph.) has made its appearance in Epping 

 Forest, for the first time in our experience. We have therefore 

 been placed in a position to compare fresh specimens of rufescens 

 with our own dark females, and we think that the chief points of 

 difference between the typical female and its two varieties may 

 be stated in the following terms : — 

 Spots behind eyes small and rounded ; meso- and uieta- 

 thorax blue, with a broad black mid-dorsal band, and 

 two narrower black lateral bands ; segments 1 and 2 

 blue, with thistle- shaped black marking on 2 ; 8 blue. ele<jans. 

 Spots behind eyes large and pear-shaped or rounded ; 

 meso- and meta-thorax orange, with a broad black 

 mid-dorsal band ; lateral bands obsolete ; segments 



1 and 2 orange, with flask-shaped black marking on 



2 ; 8 blue var. rufescens. 



Spots behind eyes small and rounded; meso- and meta- 

 thorax dark ohve-green, with a broad black mid- 

 dorsal baud; two narrower black lateral bands usually 



present, but not constant ; segments 1 and 2 dark 

 ohve-green, with thistle-shaped black marking on 2; 

 8 dark orange-brown, becoming almost black in time. var. infuscans.

The climb appears to have been a tolerably fatiguing one, 

 and Jones got badly blistered by the sun while crossing the snow 

 near the summit. I was chagrined nevertheless that my years 

 kept me ignominiously at the bottom. 



Our last and most memorable walk was to the ruins of the 

 abbey Church of St. Martin du Canigou, about three and a half 

 miles from Vernet, at a height of 8000 ft. After passing the 

 village of Castell there is a zigzag of nearly two miles over a
