216 Swiss Diurnal Lepidoptera. 



115. Gordius. Upper Valais, particularly in the Vivsch- 



walde ; not rare in July and August. In the Lower 

 Valais, a month earlier. In Italian Switzerland, still 

 more abundant ; and has been found, about Berne, in 

 August. (I have taken it at Thun also.) 



116. Chryseis. In many parts near Berne, in June and July ; 



also a variety particularly dark gold-coloured, and 

 sometimes with a beautiful play of blue, in Alpine val- 

 leys; as in the ascent from Wyler to the Gentel- 

 boden, and near Engelberg, &c. (Is not this Och- 

 senheimer's Eurybia ? which, whether a good species, 

 or a mere variety of Chryseis, is found in the Valais ; 

 but is rare.) 



117. Hippotho?. Valteline, according to Fiiessly ; probably 



in Valais also, and Italian Switzerland : but I have 

 not met with it. 



118. virgaureae. Rare aboutjBerne ; more abundant in Alpine 



valleys, where a female variety is found having a line 

 of white spots near the outer edge of the hind wings ; 

 and the male has often a black spot on the upper side 

 of the fore wings ; when he much resembles the true 

 Hipp6tho<?. 



119. Phlae'as. Everywhere in meadows, in spring and autumn. 



The spring brood seems always to afford larger indi- 

 viduals ; the variety with the inner corner of the hind 

 wing much lengthened into a tail. (Polyommatus 

 Eleus Fab. I have often found in Lower Valais.) 



20. rubi. Everywhere, in April and May. 



21. quercus. In July and August, in places abounding in 



oaks, but nowhere abundant : as it usually flies about 

 the upper branches, it is not easily taken. 



122. bae'ticus. Fiiessly has taken it in the Lower Valais, 



where Colutea arborescens, on which the caterpillar 

 feeds, is common ; but, notwithstanding all my atten- 

 tion in my frequent wanderings through this country, 

 so rich in insects, I have never met with it. 



123. spini. Near Berne, and at entrance of the Simmenthal, 



in August. Seems to be everywhere rare. 



124. ilicis. About Berne, in woods; very abundant in the 



Valais, in June and July. 



125. w. album. In neighbourhood of Berne ; but rather 



rare. 



126. pruni. In neighbourhood of Berne, in June and July; 



rarely. 



127. betulae. From the end of August till late in autumn, 



about thorn hedges and in gardens : common.
