Rhinomacer attelaboides, Fab. — This curious insect, though 

 not common, has occurred in several localities ; its larva has 

 been described by Perris, it being one of the insects of the 

 Pinus maritimus. 



Brachonyx indigena, Herbst. — I know nothing of this species 

 except that it has been taken at Rannoch by Turner, and at 

 Forres by Mr. Hislop, and that it is stated to inhabit the 

 fir in Sweden. 



Pissodes pini, Linn. — Very common at Rannoch, and has 

 occurred elsewhere ; its larva is well known, and considered 

 very injurious to the tree. 



P. notatus, Fab. — This species has suddenly become common 

 in Britain. Up till five or six years ago but a single specimen 

 was known ; about that time Turner discovered it some- 

 where in the neighbourhood of Inverness, and since then it 

 has appeared commonly in various places in England 

 and Scotland. Can it be that specimens have been intro- 

 duced with trees from abroad ? Its larva is well known, 

 and is considered injurious. 



Acanthocinus ^EDILIS, L'nn. — This is one of the most striking 

 of British beetles; it is common at Rannoch, where it is 

 called the "timber man," but is rare elsewhere. Its larva is 

 well known. 



Asemum striatum, Linn. — Found on the fir stumps at Ran- 

 noch, and in Ross-shire. Its larva is known, but not, I 

 believe, described. 



This list only includes such species as I suppose in this country 

 to be entirely confined to the Scotch fir. Numbers of other species 

 of beetlesare also found on this tree but are not exclusively confined 

 thereto. If any entomologist would give us a like catalogue of the 

 species found on this pine in other parts of Europe, we should 

 have the material for a very interesting and instructive com- 

 parison. I may mention that the pinals of the valley of the 

 Guadarrana, in the centre of Spain, are formed of this tree, and 

 that when I collected there last summer, I found a vast number 

 of species I had never seen alive before, and with them some 

 of our well known Scotch ones, notably Pissodes pini. Amongst 

 the most remarkable of the forms not found in Scotland was the
