ON SOME COLEOPTERA FROM THE FLANNAN ISLANDS 21 



Notiophilus biguttatus, F. (i specimen) ; this is again a common 

 species, the most abundant of its genus, and the most generally 

 distributed in Great Britain. 



Calathus melanocephalus, L. (6 specimens) ; this species again is 

 exceedingly common all over the kingdom ; it occurs under 

 stones, and in all sorts of localities. On high mountains it is 

 replaced by its var. nubigena, Hal., which has a dark, almost 

 black, thorax instead of the reddish thorax of the type. All 

 Mr. Eagle Clarke's specimens, however, have a distinctly red 

 thorax, though not quite such a bright red as is common in 

 specimens taken in the south. 



Trechus obtusus, Er. (2 specimens) ; this species, which is some- 

 times considered to be only a variety of minutus, F., is much 

 commoner in Scotland than in the southern part of the island, 

 and appears to be very widely distributed and very common 

 in the northern part of the country. 



The above species all belong to the group commonly known 

 as ground beetles, occurring principally under stones and 

 rubbish, and in moss. 



Ocypus ater, Gr. (i specimen); this big Staphylinid is perhaps 

 the most interesting of Mr. Eagle Clarke's captures. In Canon 

 Fowler's work on "British Coleoptera," vol. ii. p. 257, it is 

 stated to be rare in Scotland Forth district only ; but since 

 that volume was published Mr. J. J. Walker has taken it 

 at Campbeltown, and he states that it was common in that 

 locality under stones, on turf walls, etc., (see " Ent. Mo. Mag.," 

 1896, p. no). Mr. Walker also collected Coleoptera at 

 Stornoway during a visit there in 1895, but though the locality 

 was a very likely one for this species, which is found almost 

 exclusively on or near the coast in muddy places, Mr. Walker 

 did not record it among his captures taken at that locality. 

 It occurs in the Northumberland district, and therefore probably 

 will be found on the east coast as well as on the west coast of 

 Scotland. 



Philonthus varius, Gyll. (i specimen); this is a universally dis- 

 tributed species, one of the most abundant of the genus in 

 Great Britain. 



Aphodius rufipes, L. (i specimen) ; this dung beetle was caught 

 on the lantern of the lighthouse by Mr. Eagle Clarke, at 

 2.30 A.M. on September 1 1, and it is, therefore, pretty 

 certain that it must have flown over from the island of Lewis, 

 or from the mainland ; it is one of the commonest species of 

 its genus. 



Choleva grandicollis, Er. (3 specimens) ; there is a possible doubt 

 as to the identification of these specimens, as they are some-
