shire, a fair number in spruce stumps, 17th October 1916, 

 as already recorded [ante, p. 288). 



Of Tomicus acnminatns, Gyll., I have onl}' taken three 

 examples in this area : they were beaten out of dead 

 lopped-off branches of Scots pine, near Kirknevvton (Mid- 

 lothian), one on 3rd, and a pair on 14th April 1903. In the 

 same locality Pityogenes bidentatus^ Herbst, was taken in 

 some numbers on dead (cut) Scots pine branches in April 

 1903, and again in June and July last; also at Roslin in 

 October 1896, and this year at Mortonhall and Balerno (all 

 in county of Edinburgh). In West Lothian I found it near 

 Westcraigs in October last ; and East Lothian specimens 

 are from Luffness, September 1893; Gullane, August 1903; 

 and Gifford, March 1904, etc. An example (male) of var. 

 quadridens is from Bo'ness (Linlithgow), May 1901. 



Trypodendron lineatmit, F., which, owing to its habit of 

 boring well into the solid wood of spruce stumps and 

 logs, is difficult to obtain even when its presence has been 

 detected, must for the present be regarded as one of our 

 " good things." The only specimens taken in " Forth " 

 appear to be two got by myself in a spruce stump in 

 wood near Kirknewton (Midlothian), on 2nd and 3rd April 

 1903. Prof Hudson Beare was with me on the first of 

 these dates, and the specimen I then took is that recorded 

 in his notes on " Scottish Coleoptera " in the Eiitovwlogisfs 

 Record of July 1903. In May 1916, the unmistakable borings 

 of the species were discovered in a fallen spruce near Balerno, 

 but no beetle was obtained. Mr Munro has given me a 

 specimen from Eddleston (Tweed area), taken in October 

 last, and I have another which I got myself in a spruce 

 stump there in November. Search on oak and birch for 

 T. doviesticHDi^ L., a specimen of which Prof. Beare took 

 at Hawthornden in May 1905 by sweeping herbage, has not 

 as yet been successful. 



The other bark and wood boring beetles, belonging to 

 the families Curculiotiidce (Weevils), Ceranibycidce (Longi- 

 corns), etc., may next be referred to. 



Hylobius abietis, L., the well-known pine weevil, is widely 

 distributed and locally common in this area, where it has
