Alomar ia ] CLAVICORNIA. 341 



Manchester district ; Northumberland district, common ; Scotland, local, Solway, 

 Forth, and Clyde districts. 



In the last European catalogue this species is given as a variety of 

 A. atricapilla. 



A. basalis, Er. (nitidula, Heer). Ovate, convex, clothed with fine 

 ashy pubescence, black with the elytra more or less rufo-testaceous to- 

 wards apex, the colour not being sharply defined ; antennae moderately 

 long, reddish-testaceous, club narrow; thorax somewhat narrower at 

 base than elytra, half as broad again as long, feebly rounded at sides, 

 broadest before middle, very closely and rather deeply punctured, de- 

 pressed at base, basal margin raised in middle ; elytra broadest before 

 middle, closely and rather strongly punctured ; under-side black ; legs 

 testaceous, femora more or less brownish. L. If mm. 



In vegetable refuse, &c. ; also by sweeping in marshy places, especially in and near 

 osier-beds ; local ; London district, not common, Shirley near Croydon, Daren th, 

 Hammersmith ; Aylsham ; Woodbastwick ; Hastings ; Wicken Fen ; Birmingham 

 district ; Stratford-on-Avon ; Repton, common by sweeping in a marshy place near 

 an osier-bed in company with Crepidodera Modeeri ; Burton-on-Trent ; not recorded 

 from the northern counties ; Scotland, very rare, Forth district, Edinburgh. 



A. rhenana, Kr. (v. rhenana, Cat. H. E. W.). Closely allied to the 

 preceding, but broader and more convex, with the thorax rufous and the 

 testaceous colour of elytra reaching further towards base ; the antenme 

 are rather shorter and stouter ; the thorax has the sides more strongly 

 rounded and almost angularly dilated about middle, and the elytra are 

 considerably broader and more widened before middle. L. \\ mm. 



Very rare ; one specimen in Mr. Rye's collection labelled Great Yarmouth ; one 

 specimen in Dr. Sharp's collection from a marsh between Shoreham and Lancing ; eight 

 specimens, also in Dr. Sharp's collection, from Brighton ; Mr. T. Wood has taken ten 

 specimens at Bognor ; it has also been recorded from Wicken Fen ; it appears chiefly 

 to be found on or near the coast. 



There appears to be some little doubt whether this insect is the true 

 A. rhenana of Kraatz ; if not, it is probably a new species ; it certainly 

 appears to be distinct from A. basalis. 



A. mesomelas, Herbst. (dimidiata, Marsh). Very like A. basalts, 

 but more oblong, with the thorax rather narrower in proportion to elytra 

 and not so closely punctured ; it may as a rule be at once distinguished 

 from all the other species by its colour, the elytra being black, with the 

 apical half bright yellow testaceous, the colour being sharply defined ; 

 the thorax is sometimes rufous, but is usually black ; the colour, how- 

 ever, is variable, and is sometimes almost entirely dark ; the species may 

 be distinguished by the rather strong alutaceous sculpture or cross stria- 

 tion of the intervals between the punctures at base of thorax, especially 

 towards the sides. L. 1^ mm. 



Marshy places ; in flood refuse, at roots of grass, &c. ; local, but often abundant
