304 THE SCOTTISH NATURALIST 



but as showing how widely it is distributed in the Edinburgh 

 district the following occurrences, all in Scots pine stumps, 

 may be mentioned : — Woods near Kirknewton and Balerno 

 (county of Edinburgh) fairl)- common, April 1903, etc. ; 

 Dalmeny Park and Drumshoreland (Linlithgow), April 1905 

 and August 1916 respectively ; Gifford (Haddington), 

 October 1916; near North Oueensferry (Fife), November 

 1896. Though not given for Forth in Sharp's Scottish 

 Catalogue, //. ater was recorded from Craiglockhart by 

 Duncan in 1831 {JMciii. Weiii. N. H. Soc, vi., 500), and from 

 near Stirling in June 1844 by R. N. Greville (Zoo/., 698). //. 

 palliatits, Gyll., while perhaps not so common as ater, is also 

 widely distributed, occurring in spruce (chiefly) and other 

 conifers. My specimens were taken in the vicinity of 

 Kirknewton, Midcalder district, in dead spruce, Scots pine, 

 and larch, April 1903, March 1913, etc.; Balerno, March 

 1905, February 191 1, etc. ; Heriot (Edinburgh), May 191 1 ; 

 Drumelzie, Westcraigs (Linlithgow), dead, October 1916; 

 Saltoun (Haddington), April 191 1; Gifford, October 1916; 

 Cullalo (Fife), April 1897; Dollar (Clackmannan), April 

 1897; Comrie (Perth), April 1899. 



Hylesimis crenatiis, F., is common in dead, or partly dead 

 ash trees, from the bark of which I have taken it at Roslin, 

 etc., October 1896; Boghall, March 1902; Blackford Hill and 

 Craiglockhart, Februar\' 191 5; near Musselburgh, June 

 i9i6(aH in the county of Edinburgh); Philpstoun (Linlithgow), 

 April 1916 ; Gullane (one on wing), Tyninghame, and Gifford 

 (Haddington), June 1901, December 1913, and October 1916 

 respectivel)- ; Dollar, April 1897. In 1896 I found this 

 species in an elm at Comiston, near Edinburgh. No other 

 species of the genus has come under my notice here. 



Myelophilus piniperda, L., attached as its name indicates 

 to the Scots pine, is undoubtedly our most abundant bark- 

 beetle. Wherever there are pine plantations, one is almost 

 certain to find the bark of practically every dead tree riddled 

 with its borings. My notes include records from, all the 

 Watsonian counties and vice-counties (81 to 87) falling within 

 the boundaries of the Forth area. M. i/n'uor, Hart., has not 

 so far been detected in the area.
