known to occur in Switzerland. 56 1 



particularly about Denens (? Devens). In Switzerland we never 

 experience the devastations occasioned by the appearance of the 

 larvae in prodigious numbers. Great care must be taken in hand- 

 ling the caterpillar, as its brittle hairs remain in the skin, and occa- 

 sion great irritation. 



79. catax. Not rare in vicinity of Zurich. 



80. Everia. Not rare in Canton de Vaud and about Beme. 



81. lanestris. Very common everywhere. (How remarkable is the dif- 



ference in the final change of individuals of the same brood, of 

 which some appear the first, others the second, third, even to the 

 sixth year.) 



82. franconica I have found in the Valais on the Cherbenon Alp, 



where the male was flying about in mid-day, while the female re- 

 mained settled on the stems of grass. It has been found on other 

 high Alps, and very rarely descends to the plains. A female has 

 been taken in the Bremgartenwald, near Berne. 



83. castrensis. Valais, in the Viescherwalde ; about Breig, &c. ; and 



has been found in the neighbourhood of Berne, though very rarely. 



84. neustria. Very common everywhere. 



Eyprepi'a. 



(candida. Alps of Tessin.) 



85. cribrum. Very rare. A specimen in the possession of M. Mliller 



was taken near Berne. 



86. pulchra. About Geneva, and sometimes near Berne. 



87. grammica. In the Valais, about Louesch, Morel, &c, I find it 



chiefly in woods. 



88. russula. In spring ; not rare in moist meadows ; also on low Alps. 



89. plantaginis. This, which I have always taken in the North of Germany, 



in low damp meadows, is found in Switzerland on the low, and also 

 on the high Alps, as the Jura, chain of the Stockhorn, Cherbenon, &c. ; 

 in many places very common, and in numerous varieties. (On the 

 Thurnen, one of the mountains of the Simmenthal, I took, in July, 

 1833, and in the space of half an hour, and on the same spot, the 

 following varieties : — 1. The type with hind wings yellow, marked, 

 as usual, with black. 2. The black predominating and confluent, 

 so as to leave but a few yellow blotches, towards the edge. 3. 

 Ground of hind wings white instead of yellow, black markings as 

 usual. 4. Same as No. 3., except that the black markings were 

 very smaU and faint. 5. A transposition of No. 3. ; that is, the 

 ground black, and the markings white, making the hind wings uni- 

 form with the fore ones. There were also several intermediate 

 shades.) 



90. dommula. In the plains, ex., near Berne, rarely. In the valleys of 



the Bernese Oberland, ex., near Unterseen, Lauterbrunnen, &c. 

 Common. 



91. hera. In many parts of the Valais; Unterseen, Brienz; here and 



there in the Jura; in some places very common; in others, as 

 about Berne, very rare (Abundant on the Beatenberg, above the 

 Lake of Thun, and not rare at the entrance of the Simmenthal.) 



92. purpurea. A rarity in most parts of Switzerland. The larva is 



found near Berne, on Galium verum and G. -Mblliigo. In some 

 years it is rather abundant in spring; but is not easily reared. 

 (I have frequently found the larva near Thun, and never expe- 

 rienced any difficulty with it.) 



93. aulica. On the Jura, in the neighbourhood of Bienne ? As this 



information was not communicated by an unquestionable authority, 

 I insert it with doubt.
