Atomaria.] CLAVICORNIA. 339 



with a strong transverse depression bounded by a fold on each side 

 posterior angles right angles, sparingly and finely but distinctly punc- 

 tured; elytra plainly and moderately strongly punctured at base, punctua- 

 tion evanescent towards apex, dark, with shoulders and apex lighter ; 

 legs reddish. L. 2 mm. 



In haystack refuse ; rare ; Lee, Kent, one specimen (Sharp) ; Scarborough (R. 

 Lawson); Stretfbrd, near Manchester, under refuse, banks of Mersey (Chappell) ; 

 Northumberland district, rare, Banks of Irthing (Bold). 



A. fuscata, Sch. Oblong-oval, not very convex, varying in colour 

 from dark pitchy-brown, almost black, to brownish-testaceous, clothed 

 with rather fine greyish pubescence ; antennae moderately long and stout, 

 ferruginous or reddish-brown ; thorax very transverse, with sides gently 

 rounded, thickly and distinctly punctured, transverse basal impression 

 rather deep, basal margin raised in middle, posterior angles almost right 

 angles ; elytra not so closely punctured as thorax; legs lighter or darker 

 brownish or testaceous. L. 1| mm. 



In haystack refuse, manure-heaps, &c. ; rather common and generally distributed 

 throughout England ; Scotland common, Solway, Forth, and Clyde districts ; Ire- 

 land, Killarney and near YVaterford, and probably generally distributed. 



Owing to the great variation in colour this is often rather a puzzling 

 species ; dark specimens somewhat resemble A. atra, but that species may 

 be distinguished by its broader and longer and much more convex thorax 

 as well as by its deeper punctuation ; light examples are very like 

 ordinary specimens of A. berolinensis, but that species has the elytra 

 shorter and more convex, and the sides of the thorax less rounded and less 

 dilated about middle ; the punctuation also of the thorax is not quite so 

 close and strong ; it is sometimes confounded with A. apicalis, which, 

 however, is quite differently shaped (being much more narrowed in front 

 and behind), and has the elytra more sparingly and strongly punctured 

 and pubescent. 



A. atra, Herbst. Oval, convex, deep black, shining, clothed with 

 short and fine greyish pubescence, which is rather scanty ; antennae 

 moderately long, reddish-testaceous with club usually darker, compara- 

 tively widely separated at insertion ; thorax not very transverse, nar- 

 rowed in front, but with sides very slightly rounded, almost straight, 

 behind, strongly convex, depressed at base, rather coarsely and deeply 

 punctured ; elytra broadest before middle, rather plainly punctured to- 

 wards base, obsoletely towards apex, apex usually reddish-brown ; legs 

 testaceous or brownish-testaceous, femora darker. L. 1^ mm. 



Damp places, by sweeping, &c. ; rare ; Hammersmith Marshes (one specimen, 

 Waterhouse) ; Leigh, Kent (one specimen taken by Miss Shepherd on banks of Med- 

 way) ; Mickleham ; Cowley; The Holt, Farnham (Power) ; Hastings; Stoke Wood, 

 Devon, old fungi (this record may be in error) ; Slapton Ley, Devon, and Withington, 

 Gloucestershire (Wollaston) ; Loch Gclly, Scotland (Power) ; Ireland (Haliday).
