bear a superficial resemblance to a small S. monilicorne, but is much 

 more closely related to R. vile ; its very short antennae will distinguish 

 it from the allied species. L. 2| mm. 



Under bark, in rotten wood, &c. : introduced by Rev. A. Matthews on the autho- 

 ri y of a specimen taken by him in 1862, at Gumley, Leicestershire : Mr. Rye refers 

 to this species some specimens taken by Mr. J. Hardy, at Wooler, Northumberland 

 district, in fungus on alders, and also the specimens taken by Dr. Power, at Balmuto, 

 Fifeshire, which have been distributed by him as H. gracilicorne : I have not seen the 

 former specimens, but he can hardly be right with regard to Dr. Power's specimens, 

 which have the antennae quite as long, if not longer, than H. vile. Dr. Sharp records 

 S. irevicorne as rare in Scotland, in the Solway, Forth, and Dee districts. 



K. gracilicorne, Fairm. This species closely resembles H. vile, 

 but diifers by being larger, by the antennae having the first five joints 

 only testaceous, and by the somewhat stronger punctuation of the 

 head and thorax ; the latter is much rounded at the sides in front, and 

 the anterior angles are scarcely marked, the impressions on the disc are 

 almost absent, the punctuation of the elytra is coarser but less close, and 

 the elytra are less black, and a little reddish at base and apex, with the 

 strise hardly at all marked ; compared with H. hrevirorne it is smaller, 

 narrower, lighter, with the dorsal depressions on the thorax considerably 

 more obsolete, and the sides of the same more rounded and less con- 

 tracted behind ; the penultimate joints of the antennae are not so trans- 

 verse, the antennte themselves being longer, and the punctuation of the 

 elytra is not so close ; the hind body also is duller. L. 2| mm. 



Under fir-bark; rare; one specimen from the London district (Rye); Scotland, 

 Balmuto, Fifesliire, in numbers (Power) : Dr. Power's specimens appear to agree well 

 with Fairmaire's description ; there is, however, considerable confusion with regard 

 to these last two or three species ; according to the catalogue of Heyden, Reitter, and 

 Wei-ise, the H. gracilicorne of Fairnuiire, which they mention as from Britain, is a 

 different insect from the if. gracilicorne of Rye, which is considered by them to be 

 synonymous with H. vile, Er. ; this, however, can hardly be correct, as Mr. Rye was 

 too keen an observer to have confused the species in this fashion. 



K. iopterum, Steph. (lucidum, Er.). Eeddish testaceous with the 

 head black, the hind body more or less broadly pitchy towards apex, or 

 entirely dark, and the elytra with suture and apex, and sometimes tlie 

 rcreater part of its surface black or bluish black ; head rather thickly and 

 strongly, but variably punctured ; antenna3 short and stout, entirely red, 

 or occasionally darker towards apex, penultimate joints strongly trans- 

 verse ; thorax almost as broad as elytra, transverse, but not strongly so, 

 rounded at sides, posterior angles right angles, thickly and moderately 

 punctured, dorsal foveas obsolete or absent ; elytra scarcely twice as long 

 as thorax, strongly and thickly punctured in distinct striated lines ; 

 hind body very finely alutaceous and punctured. L. 2|-2| mm. 



Under bark, in cut grass, on flowers, &c. ; local ; London district, not uncommon, 

 and generally distributed; Glanvilles Woottou ; New Forest; Devonshire; Dean 

 Forest ; Montgomery ; Yardley and Knowle, near Birmingham ; Salford Priors ; 

 Sherwood Forest ; Robins Wood, Reptou ; Lincoln ; Manchester district j rarer
