of the insect, although it appeared in successive British 
lists, until 1908, when the late Dr G. W. Chaster! recorded 
the capture of four specimens under bark of chips in 
Dumbartonshire in the autumn of 1907. In Igog I dis- 
covered it in fair numbers,? under bark in a Lanark- 
shire locality, and it has apparently gained a firm footing 
there as specimens can always be found at some time 
of the year. It next appeared in Linlithgowshire, where 
Dr Malcolm Cameron informed me that he had found 
two specimens during 1913. Again in the west it was found | 
by Mr A. Adie Dalglish, in some numbers under bark 
in Renfrewshire; and I took it in another locality in the 
same county in the beginning of 1915. In the autumn 
of the same year I came across it when working for bark 
beetles in Main Argyll; in the Supplement to the Coleoptera 
of the British Islands by Fowler and Donisthorpe (1913), 
it is recorded as having been taken by Dr Joy at 
Pitlochry, Perthshire. Mr A. H. May tells me that he 
found it in another locality in Renfrewshire during September 
1916. Mr J. E. Black? recorded it as fairly common in 
Peeblesshire during October 1917. My latest capture of 
crenata was in October 1920 when I found it not uncommonly 
in still another Renfrewshire locality, making the fourth 
station for the beetle in that county. 
The ascertained distribution of the insect in Scotland 
to date, arranged according to the Vice-County System, 
stands thus :— 
76. Renfrew (four localities). 88. Mid-Perth ? (original record). 
77. Lanark. 89. East Perth. 
Voobeebles: 98. Main Argyll. 
84. Linlithgow. 99. Dumbarton. 
It has accordingly occurred in ten additional localities in 
seven vice-counties after an interval of forty or forty-one 
years, and it is worthy of note that its presence in these 
localities has only been brought to light within the com- 
paratively short period of about thirteen years.
