STRIPED PINE-BORING BEETLE. 93 



few observations, together with specimens of both kinds of beetles, 

 also of larvae and pupae, and specimens of tunnellings of T. domesticum 

 in felled Oak. 



The observation of T. lineatum in England (as distinguished from 

 Scotland) appears to me to be of a good deal of interest, as, so recently 

 as 1895, I find it observed that " The species is widely distributed 

 throughout Europe, but is confined in Great Britain to a few localities 

 in the Tay and Dee districts of Scotland, where it has not yet proved 

 injurious." 



I find also the following by the excellent authority the late 

 E. 0. Eye, F.E.S.,* of his personal observation of it in Scotland, in 

 wording that seems to point to his not considering it to be an English 

 species : — 



" Xyloteriis lineatus, an elegantly striped insect, with more pre- 

 tensions to beauty than its allies, is found (rarely) in Scotland. I 

 have seen it with its head and thorax protruding from its neat circular 

 drill in the solid wood of felled Pines ; but it is oftener seen than 

 taken, owing to its habit of backing quickly to an indefinite depth into 

 its burrow on the approach of the bark knife. In this species the 

 ■antennae have a rounded club, whilst in the other (domesticus) the club 

 is pointed."— (E. C. E.) 



From the above passage, and also from only the above-named two 

 species being noted in his list of British beetles (p. 265 of work 

 referred to in note), it would appear that then and up to 1890 (the 

 date of the second edition by the Eev. Canon W. W. Fowler, F.E.S.) 

 only these two species were recorded as British. 



But it should perhaps be just noticed that there is yet another 

 species, the Trypodendron {= Xyloterus) quercus of Eichhoff, which is 

 mentioned by him + as infesting the wood of various deciduous trees, 

 and which is very shortly referred to by Prof. Fisher, in the work 

 mentioned below (p. 232), as much like lineatum in appearance, but 

 distinguishable by the club of the antennae being angulate at the 

 extremity. In this respect, as well as in its habits, it is stated to 

 resemble T. domesticum, "but is much less common in Britain, being 

 almost entirely confined to the neighbourhood of Sherwood Forest." | 

 From the exceedingly small amount of presence with which this species 

 is credited in England, it seems hardly worth while to refer to it, 

 excepting relatively to the confusion regarding the nature of trees 

 attacked by T. lineatum, the really, solely Pine-boring species, which 

 is considered by Herr Eichhoff wholly to have arisen from insufficient
