392 STAPHYLiNiDiE. \_Thinohius. 



E.:ii)iioch ; it appears to be very rare on the Continent, as Kraatz, its flescriber, knew 

 only of two examples ; it is the largest species ot the genus at present known. 



T. linearis, Kr. {longicornis, J. Salilb., luteipennis, Rey 1 Thino- 

 philus linearis, Rey). Much smaller than the preceding, pitchy brown, 

 "vvith the elytra lighter, clothed with very fine and close greyish pubes- 

 cence ; head as broad as thorax, with two very distinct furrows in front, 

 transversely subquadrate ; punctuation of head and thorax very fine, 

 thick, and obsolete ; antennse moderately long, thickened towards apex, 

 testaceous, with the apex sometimes a little darker, joints 5-8 varying 

 somewhat in size ; thorax strongly transverse, almost truncate in front 

 and rounded behind ; elytra almost twice as long as thorax, very finely 

 and thickly punctured ; hind body elongate, almost as broad at base as 

 elytra, very thickly punctured, shining at apex, sixth segment slightly 

 sinuate ; legs testaceous with the femora sometimes slightly darker. L. 

 1^ mm. 



In sand on the banks of rivers, streams, and lochs; rare; Scarborough (Wilkinson) ; 

 Scotland, scarce, Solway, Forth, and T^iy districts; Dr. Sharp has found it in com- 

 pany vvith Homalota suhtilissima, to which it bears a great superficial resemblance. 



T. brunneipennis, Kr. (sub-gen. T/n7ioj)Jn'lus, Rey). Very closely 

 allied to the preceding, but a little broader, with the head and thorax 

 more thickly punctured and pubescent and so duller ; the general colour, 

 moreover, is darker, and the posterior femora are more often darker ; 

 the antennae are rather shorter and stouter, and have joints 4-8 sub- 

 equal, and almost as broad as long or subtransverse ; the thorax is more 

 strongly rounded at sides and contracted behind, and the elytra are a 

 little shorter in proportion. L. 1^ mm. 



Very rare ; Scotland, Tay district. It was first recorded by Mr. G. Waterhouse as 

 from Scotland, Rev. W. Little's collection (Ent. Ann. 1859, 137). 



T. longripeniais, Heer. (cilfatvs, Kies.). This and the next species 

 are easily distinguished from all those that precede by their smaller 

 size, less linear form, and the fact that the head is evidently narrower 

 than thorax, somewhat rounded, or even subtriangular ; this species is 

 dull black, with the elytra brownish, clothed with very fine ashy pubes- 

 cence ; the whole upper surface is very finely, and scarcely visibly, 

 shagreened ; antennse slender, dark testaceous or brownish with the basal 

 joints lighter, joints 4-10 at least as long as broad or subtransverse 

 (this difference is probably sexual) ; thorax very strongly transverse, 

 slightly and very broadly emarginate at apex, with the anterior angles 

 almost right angles, rounded, but not much narrowed, behind, without 

 impressions ; elytra more than twice as long as thorax ; hind body a 

 little narrower than elytra, not elongate, sixth segment slightly sinuate 

 in middle of apical margin ; legs lighter or darker testaceous : the general 

 colour, however, of the whole insect is variable and differs consideraljly 

 according to the localities in which it occurs ; this is especially noticeable 

 in continental specimens. L. 1 mm.
