558 Nocturnal Lejridoptera 



NOCTURNA. 



Satu'rni^. 



1. pyri. About Neufchatel, in Canton de Vaud, about Geneva, in 



Lower Valais, and in Tessin : has been once only found near Berne. 

 Its district appears to commence beyond the Saane and the Aar, 

 and to spread thence over Western Switzerland. 



2. carpini. Everywhere ; but not in every year equally abundant. 



Agli x ^. 



3. tau. Very common in beech woods, as soon as the leaves are ex- 



panded. 



E'ndromis. 



4. versicolora. In Argovie and the vicinity of Winterthur : found once 



near Berne. 



Harpy n ia. 



5. vinula. Common everywhere in May and June. Later, the young 



larvae are very easily found on willows and poplars. The pupa 

 often remains two full years before it assumes the perfect state. 



6. erminea. Very rare. (Then follows a detailed account of raising 



some from the egg, with the appearance of the larva after each 

 change of skin.) 



7. bicuspis. I am not quite certain whether this is really a native of 



Switzerland; if it is so, it is extremely rare. (It certainly has been 

 found in Switzerland. Boisduval makes this and the next merely 

 varieties of furcula ; and, so far as my own observations go, I think 

 him perfectly right.) 



8. bifida. Near Berne ; rather rare. 



9. furcula. Near Zurich and Winterthur, &c; but everywhere rare. 



(I have found the larva near Thun.) 



10. ulmi. Has been found near Winterthur. 



11. fagi. Rare. The queer-looking caterpillar is found on oaks, hazels, 



beech, lime trees, &c; and is rather difficult to rear until its final 

 change. 



12. Milhaiisen. Very rare; has been found at Winterthur. 



Notodo'nta. 



13. tritophus. Has also been found near Winterthur. 



14. ziczac. On poplars and willows ; rather common. 



15. Dromedarius. Near Winterthur. 



16. camelina. Near Berne and other places ; not rare. 



17. carmelita. Is probably found in Switzerland; but a doubt exists as 



to the identity of Fiiessly's insect, in consequence of his having a 

 wrong reference to Linnaeus. 



18. Dictse N «. About Berne and other places, but seldom. (I have found 



the larva occasionally near Thun.) 



in insects which undergo metamorphosis, and is it so ? " They [the cater- 

 pillars of Nematus ribesii] are generally said to be extremely voracious ; 

 but this is owing to their great numbers ; for, upon an average, each cater- 

 pillar barely eats one leaf during its whole life; the female eating more 

 than double of what the male eats. For the first five or six clays they eat 

 very little; each, at that time, having made only a small hole in the leaf of 

 about one tenth of an inch in diameter. It is in the last four or five days 

 that they make the havoc on the bushes ; and the damage is therefore 

 nearly all done before it is discovered."!
