 space on centre of disc ; antenna3 red, shorter than in the preceding 

 species, with joints 4-10 gradually a little shorter, penultimate joints 

 not strongly oblong ; thorax long, parallel-sided, strongly and coarsely 

 punctured, with a smooth central line ; elytra somewhat variable, usually

 tubercles at base of impression. 



In flood refuse, moss, dead leaves, &c. ; in marshy places ; also under stones on 

 sides of hills, at roots of grass and plants near the sea-shore, &c. ; local, but not 

 uncommon; London district, widely distributed; Hastings; New Forest; Hythe ; 

 Malvern Hills (common under stones in sprinir) ; Midland districts, common ; North 

 Wales; Bridlington, Yorkshire ; Liverpool; Nortliuinberland district, rare ; Scotlantl, 

 rare, Tweed, Solway, and Argyle districts ; Ireland, near Dublin ; it is much rarer in 

 the North than in the Midlands and Southern districts. 



Xa. ang"usticolle, Lac. {lonriicorne, Redtb., carhiotum, Bold). A 

 very distinct and elegantly shaped species, shining black, with the elytra 

 bright red with base sharply black ; head someAvhat orbicular, large, distinctly 

 broader than thorax, rather deeply and closely punctured ; antennae long 

 and slender, dark pitchy red, longer than head and thorax united, with 

 all the joints elongate ; thorax long, much narrower than elytra, rather 

 thickly punctured, with a plain, smooth, somewhat raised longitudinal 

 space in centre ; elytra evidently longer than tl^orax, rather strongly 

 punctured in somewhat irregular rows which are more distinct towards base ; 

 hind body very finely and thickly punctured, clothed with fine greyish 

 pubescence ; legs black, tarsi red. L. 7 mm. 



Male with the seventh ventral segment broadly impressed in middle, 

 with the impression rugose in front and smooth behind and bounded on 

 each side by a longitudinal crest or tuft of black hairs, apical border 

 sinuate. 



In flood refuse, &c. ; rare ; Oernant, near Llangollen, one specimen under a stone 

 (Chappell) ; Northumberland district, rare, Devil's Water and Irthing (Bold); Scot- 

 land, Tweed, Forth, and Solway districts (Sharp, Allen Marker, &c.) ; lieland, banks 

 of Dodder near Firhouse, Dublin (McNab). The species has been obtained some- 

 what freely by Dr. Sharp in flood refuse ; the refuse must be examined almost as soon 

 as it has been thrown up, aa the insect appears to leave it almost immediatel3'. 



ACHENIUM, Curtis. 



This genus comprises about twenty-five species which are chiefly con- 

 fined to Europe and the adjacent regions ; three or four species occur in 

 Madeira and the Canary Islands, and one is recorded from the East 

 Indies ; in many respects they resemble Latlimhiiim, but are easily dis- 

 tinguished by their exceedingly flat, depressed form ; to judge by their
