 G-6i mm. 



Marshy places, near banks of rivers and ponds ; also imder bark of ftiUen trees, by 

 sweeping rushes, &c.; local but not unconunon and widely distributed throughout 

 England. Scotland, very local, Tay and Solway districts. Ireland, near Dublin. 



A scitulus, Dej. Very sliining, black, with a greenish tinge on 

 the elytra, which is often hardly perceptible: it differs from A. mirans 

 in being smaller and narrower; the thorax is more obliquely sloped 

 and narrowed l;ehind, with smoother disc and deeper dorsal furrow ; the 

 elytra also are much narrower and more convex : in size and general 

 appearance it resembles most closely A. gracilis, but besides the fact 

 that the latter insect presents no trace of a greenish reflection, A. 

 srifulufi differs from it in being more shining, and in having the sides 

 of the thorax more plaiidy rounded, with margins more reflexed at base 

 and the basal foveas deeper, and also in having the elytra more strongly 

 striated. L. 5|-6 mm. 



Marshy places, at roots of grass, &c. ; not common ; Pntuoy ; Hammersmith ; Lee* 

 Ilej)toii ; Hath ; Forest of Dean. Not recorded from the north of England, Scotland, 

 or Ireland. 



A. fulig-inosus, Panz. Black or pitchy Ijlack, elytra often pitch- 

 brown ; thorax as long as broad, somewhat narrowed behind, posterior 

 angles rounded but traceable, dorsal line distinct, basal fovese near 

 angles smooth, basal margin about two-thirds as broad as anterior 

 margin ; elytra ovate with sides rounded, striated, the striaj very feebly 

 punctured ; legs pitchy. L. 6-6| mm. 



Damp and marshy places ; common and widely distributed throughout the king- 

 dom ; not recorded from the extreme north of Scotland. 



A. gracilis, (lyll. Smaller than the preceding, entirely lilack, with 

 antennie and legs also black ; the thorax is wider in front and less con- 

 tracted behind, and the posterior angles are completely rounded ; the 

 shoulders are more prominent, and the elytra are less strongly stiiated, 

 with the sides more parallel : in general contour it approaches most 

 ncai'ly to A. pireiis, but that species is i)Iainly larger, and always has the 

 elytra pitchy-brown, and also has the posterior angles of thorax less 

 rounded, and the anterior and po.sterior nmrgins of the latter nearly 

 equal, whereas in A. gracilis the posterior margin is plainly the narrower. 

 L. 5^-G mm. 



Damp and marshy places ; rather local, bnt widely distributed and not uncommon
