This is a discussion of a paper on the conditions in the virj^in forest 

 of Bialowies [R.A.E., A, viii, 419]. The striking resemblance of 

 entomological conditions in Alpine forests to those olDserved at 

 Bialowies is pointed out ; the preponderance of secondary insects 

 and the abundance of natural enemies are features common to both. 

 The author entirely agrees with the conclusions reached by Escherich 

 as to the need of bringing cultural methods as far as possible into line 

 with natural conditions.

The special character of forest insects in Switzerland is very marked. 

 The Cantharid, Lytta vesicatoria, occurs in the Canton of Valais up 

 to about 5,200 feet. In high situations Pytho depressus is quite common, 

 especially on Finns cenibra. Cerambyx heros, common in Germany, 

 the pine moth [Fanolis flammea] and Rosalia alpina are of little 

 importance in Switzerland. Cossus cossus {ligniperda) is common 

 up to about 3,300 feet, while Zeuzer a pyrina (C. aesculi) is rare. The 

 nun moth [Liparis monacha'] occurs in places, but outbreaks of it are 

 unknown, and Dendrolimus {Gastropacha) pini is equally unimportant, 

 l)ut is replaced by the pine processionary caterpillar, Cnethoeampa 

 pitvocampa, which is a permanent and severe pest, especially at 

 altitudes of about 3,000 feet. 



The peculiar characters of the Swiss forest fauna are most marked 

 in the mountain forests of the Alpine districts, into which many species 

 from the ])lains have penetrated and even increased, probably because 

 they encounter less competition. These include Galernca capreae, on 

 alder and birch, Stilpnotia {Leucoma) salicis, on poplar and willow, 

 Lyda crytlirocepliala and other sawflies, and Chennes spp., such as 

 C. ahietis and C. strohilohius. 



Species pecuhar to high mountains, some of which also occur in 

 the Arctic regions, include the bark-beetles, Ips {Tomicus) cembrac 

 and /. (T.) bistridentatus , infesting Finns cenibra ; the larch moth, 

 Enarmonia diniana [Steganoptycha pinicolana), which causes great 

 damage in Valais and the Engadine ; Ocnerostoma piniariella ( Tinea 

 copiosella), infesting Finus cenibra; an Aphid, Lachnus pinicolns ; 

 and a Coccid, Futo (Futonia) antennata.

Acanthocinus aedilis, L., has two generations a year, one in 

 May and June and one in autumn. The eggs are laid in cracks in the 

 bark of stumps or felled trunks. After a few days the larva hatches 

 and bores into the inner bark. In three to four weeks the larva
