Atoniaria ] clavicornia. 341 



Manchester district; Nortliuuiberluiul district, couiuion ; Scotland, local, Solway, 

 Forth, and Clyde districts. 



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

 A. atricapilla. 



A. basalis, Er. {nitidula, Heor). Ovate, convex, clothed with tine 

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

 Avards apex, the colour not being sharply defined ; antennas moderately 

 long, reddish-testaceous, club narrow ; tliorax 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. 1| mm. 



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

 osier-beds; local; London distri't, not common, Shirley near Croydon, Darenth, 

 Hammersmith ; Aylsham ; Woodbastwiek ; 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-ou-Trent ; not recorded 

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



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 tovvards base ; the antennai 

 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. 1| 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. hasalis. 



A. mesomelas, Herbst. {dlmidiata, Marsh). Yery like A. hasalis, 

 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 usuall}' 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, kc ; local, but often abundant
