underneath, and sometimes entirely so), and especially by having the 

 strife of the elytra distinctly, though finely, punctured : the insect, 

 moreover, is evidently less depressed, more shining, and of a brighter 

 aeneous colour. L. 5 mm. 



Shores of Loch Maree, Ross-shire, Scotland. 



This species was taken not uncommonly by Mr. Champion and Mr. 

 R. W. Lloyd on July G, 1892, and was introduced as British by Mr. 

 Champion, who had placed it in his collection near B. jn-asinnm and 

 forgotten it, in 1895 (Ent. Mo. Mag. xxxi. (2 Ser. vi.) 203). It has 

 occurred in Sweden, Lapland, Finland, Norway, and Switzerland, but 

 has not been recorded from Germany or France, As both Gyllenhal's 

 and Sahlberg's descriptions appeared in 1827, it is not quite certain 

 which of the above names has priority, but as Mr. Champion (I.e.) says 

 it may be remarked that C. R. Sahlberg himself quotes Gyllenhal's 

 name, at the same time using that of B. jtfi^tfi for the insect. 



B. argenteolum, Ahr., Neue Schrift. Hall. Gesells., ii. 2, 23, 

 8, t. i., f. 12. Closely allied to B. jmludosum, Panz., with which it iias 

 been confused in collections, but distinctly larger and more robust, 

 with the thorax more evidently broader than long and the posterior 

 angles sharp and prominent : in B. ^mhcdosimi the thorax is at most 

 slightly broader than long, and the posterior angles are not prominent ; 

 the colour, moreover, of the latter insect is dull, or very dull, whereas 

 B. argenteolum is more shining and more dintinctly bronze ; this 

 character, however, is somewhat variable. L. 6 mm. 



Ardmore, Lough ISTeagh, Ireland (Rev. W. F. Johnson). 

 The Rev. W. F. Johnson first captured this species in June 1899, 

 and it was introduced as British by Mr. Johnson and Mr. J. N. Halbert 

 in their excellent "List of the Beetles of Ireland" (Proceedings of the 

 Royal Irish Academy, 3 Ser., vol. vi., No. 4, p. 587). The Irish records 

 hitherto existing for B. jxdudosum must be referred to this species. 



Apart from the difierences above mentioned the hue of the antennse 

 and the tibiae are lighter than in B. jMludosum : in the latter species 

 the tibiae are in my specimens almost entirely black, whereas in the 

 specimens of B. argenteolum, kindly given me by Mr. Johnson, they 

 are almost entirely red ; the characteiistic impressions on the elytra 

 are said to be oblong in IL pahidos-iim and quadrate in B. argenteolum. 

 I cannot see much difierence in this respect, but in my specimens of 

 the latter species they are less marked than in B. paludosum. 



B. argenteolum has been recorded fiom Germany, Korfcfeern France, 

 Sweden, and Siberia, 



TRECHUS, Clairville. 

 T. subnotatus, Dej. Spec. v. 18. Pitchy, with an oblong spot on 

 shoulder, a subrotundate one before apex, and the inflexed margin of 

 elytra, testaceous. Antenna with the second joint shorter and thicker 

 than fourth. Thorax subcordate with sides a little arched, and posterior 

 angles small, prominent and acute. Elytra sub-oblong-ovate, punctate-
