Swiss Diurnal Lepidoptera. 217 



Papi'lio. 



128. Machaorc. Common everywhere on hills, in May and 



August. 



129. Podalirius. More rare than the last. On this side of 



the Alps it appears but once, in spring. In the Va- 

 lais it appears a second time, in August ; and is there 

 extremely common, particularly about Sion. (I have, 

 however, taken it " on this side the Alps," near 

 Thun, in July, August, and September.) 



Zery'nthi^. 



130. Polyxena. According to Fiiessly, this fine insect was 



once taken near Locarno. 



DoriVis. 



131. Apollo. In sunny spots on mountains and in valleys, 



at a moderate elevation, particularly on stony slopes; 

 abundant in the Jura, from July to autumn ; never 

 found above the limits of the deciduous woods. (Not 

 usually, certainly ; but I have occasionally met with 

 it far beyond. Meisner describes a hermaphrodite, 

 left side male, right side female, which he took on 

 heights of Tourbillon, Sion, Oct. 10. 1816.) 



132. Delius (Phce'bus). Chiefly on the Col de Balrne ; also 



in the Valais and the Grisons, on the Gemmi, Hah- 

 nenmous between Lenk and Adelboden, &c. (Not 

 rare on the Kiley, eight leagues from Thun. Meisner 

 says he has a remarkable variety from Chamouni, in 

 which the spots usually red are black, except those on 

 the front edge of the fore wings : and Ochsenheimer 

 observes that his specimens of the same kind are 

 counterfeit, the red spots on the hind wings being 

 covered with a sort of varnish ; which was not removed 

 by moisture, but could be detached with the point of 

 a fine penknife.) 



133. Mnemosyne. Grisons, in lower mountain pastures, and 



in the Valteline, on reclaimed Alps (zahmern Alpen). 

 I first found it, in 1802, in the Surenenthal ; and 

 again, in 1809, in the Gentelboden, near the com- 

 mencement^ the Engstlen Alp, at a tolerably great 

 elevation. Abundant in May, at foot of the Kiley.) 



Po'nti^. 



134. cratae^gi. 



135. brassicse. 



136. rapae. Very common everywhere.
