Beitrag zur Kenntnis der Halticinenfauna Mittel- und Süditaliens. 169 



I took up the matter again and found not only niy old observa- 

 tions corroborated, but also, and especially this autumn (1909) observed 

 a new, and it seems to rne very interesting, circumstance viz that the 

 Boring Beetle very often also knocks in an energetic way 

 before (as a rule some few hours) the coming barometrical mini- 

 mum has been able to induce movements on the barometer. 



This has been exceedingly interesting to me. 



Whether the Anobium can be considered as a good and tiiie weather 

 prophet or not may of course, if I can say so, in the first line become 

 a question of curiosily. That more or less strong alterations in the air 

 depressions directly or indirectly are able to cause the insect to act in 

 some way, in casu to knock, might, I think, be explained in a some- 

 what natural way, but that the insect acts still before the giass begins 

 to fall, that means before the air depression has reached the place, is 

 very surprising, and it gives a hint of forces (electrical?), of which we 

 tili now, as far as animal activity goes, are not fully acquainted of. 



I feel sure that every Entomologist, who has the opportunity of 

 studying the Boring Beetle, may be pleased in observing its knocking 

 in relation to the change of weather or the barometrical minima, 

 and I also feel convinced that he will not only be able to corroborate 

 m}^ observations but also to add new facts to them. But I may as 

 well notice that this study must be the sake of the entomologists of 

 the „country". Those who live in the towns will not have the best 

 opportunity. The noise in large cities will quite suppress the little 

 fellow's, let US say, calling its better half part!
