 land, in 1903, had a very curious aspect. 



A curious old Entomological Book. — Mr. Hamilton 

 Druce exhibited a book he had lately come across entitled 

 " The indigenous insects of the region of Petersburg," by 

 John Cederhielm, published at Leipzig in 1798, and made 

 remarks upon it. 



Mr. A. H. Jones and Mr. W. G. Sheldon commented on 

 Mr. Druce's observations with regard to the occurrence of 

 Papilio machaon in various parts of Russia. 



A British ( ?) Sirex juvencus. — The Rev. F. D. Morice 

 exhibited a specimen of true Sirex juvencus, $, F., from 

 Wakefield in Yorkshire, given to him by Mr. J. W. Saunt of 

 Coventry, who received it with several others from Mr. W. 

 Fletcher of Wakefield. Mr. Morice made the following 

 remarks on this exhibit : — 



A joiner employed by Mr. Fletcher found in the course of his 

 work a piece of timber infested by these insects and brought it 

 to his employer. Unfortunately, Mr. Fletcher has not been able 

 to ascertain whether this particular piece of timber was of 

 British or foreign origin. If the latter, it must have come 

 from Riga, and perhaps this is the most likely explanation 

 of the matter; but as I know of one and only one other 

 reliable record of juvencus as a British-born insect, and in 

 that case also the locality was a Yorkshire one — viz. Doncaster 

 (where it was taken by Mr. Bayford in, I believe, 1904) — it 

 seems worth while to exhibit it. 



Nearly all British records of juvencus really refer to another 

 species, viz. noctilio, which differs from it in having entirely 

 black antennae, and seems to be, if not actually indigenous, 

 at least thoroughly established in many British localities. 

 But yet another species (viz. cyaneus, F.) also figures as 

 juvencus in some collections. This, however, is certainly 

 not a Palaearctic but an American insect, and all occurrences 

 of it here must be accounted for by the accidental importa- 

 tion from Canada or the States of timber containing its 

 larvae.
