H. laevig-atus, Panz. {fenestratus, Thunb. ; H. marginatus, var. b. 

 Gyll.). Very like the preceding, but distinguished by the character 

 of its pubescence, which is thick, fine, short, and silky, and not inter- 

 mingled with hairs of another character ; the posterior angles of the 

 thorax are not so distinctly margined, and the clypeus in the male is 

 armed with two short spines ; this sex is also distinguished by its 

 longer form, larger head and elongate mandibles, and by having the 

 thorax as broad as the elytra ; the ridge on the first abdominal segment 

 is finely notched in front in both sexes ; the elytra in this species have 

 a more powdery and lighter appearance than in H. marginatus, and the 

 yellow markings are not nearly as distinct in most specimens. L. 3- 

 4 mm. 



Banks of ponds and ditches ; local, and apparently not found further north than 

 the midland counties ; London district, rather common, Lee, Penge, Wandsworth, 

 Darenth Wood, Dulwich, Cowley, Gravesend; Norfolk; Suftblk ; Hastings; Glan- 

 villes W^ootton ; Southsea; Weymouth; Bewdley, Worcestershire (Blatch). 



K. fusculus, Kies. Oblong, moderately convex, but with disc of 

 elytra depressed, blacky clothed with fine, short, even, brownish or 

 brownish-grey pubescence, without any intermixture of longer hairs ; 

 antenuce brown, first joint sometimes brownish-yellow ; thorax at base 

 about as broad as elytra, rather strongly narrowed in front, very finely 

 punctured, posterior angles sharply margined, anterior angles often 

 j^ellowish ; elytra finely, but rather distinctly sculptured, with distinct 

 and well-marked yellow spots and patches ; epipleura3 fuscous black ; 

 legs black or pitchy-black with tarsi and sometimes femora lighter ; 

 ridge on first abdominal segment quite smooth in female, finely notched 

 in male. L. 3 mm. 



On mud near ponds and ditches ; extremely local ; I know of no other locality 

 except Luicombe Chine, Ventnor, Isle of Wight, where it occurs in numbers on mud 

 at some little distance above the shore beneath the cliffs ; all Dr. Power's specimens 

 are labelled Isle of Wight, and probably come from this locality, w^here I have taken 

 it with Dr. Sharp and Mr. Gorham. 



The species rather closely resembles H. hevigatus, but may be known 

 by its small size and comparatively stronger punctuation, 



K. sericans, Kies. Oblong, black, or more often reddish-black, 

 sometimes ferruginous, clothed with short whitish silky pubescence ; 

 smaller and narrower than any of our other species ; head rather large, 

 antennae yellow ; thorax usually darker than elytra, sometimes reddish 

 with disk darker, about as broad as elytra, narrowed in front, very 

 finely and thickly punctured, posterior angles finely margined ; the 

 central longitudinal line is usually red or reddish ; elytra thickly and
