332 CLAVICOBNIA. [Atomaria. 



with the thorax usually darker than the elytra which are often 

 brownish-red, clothed with fine pubescence ; antenna 3 , ferruginous, stout, 

 closely approximate at base, with the first joint much developed and 

 distinctly curved on the outer side, last joint plainly narrower than 

 penultimate ; thorax convex as long as broad, moderately rounded at 

 sides, distinctly punctured, base evenly margined, all the angles blunt 

 or rounded ; elytra parallel-sided, somewhat depressed on disc, dis- 

 tinctly but not strongly punctured ; legs testaceous or reddish-brown. 

 L. 2 mm. 



In moss, and in flood and vegetable refuse ; rare ; Dulwich, Carshalton ; Repton ; 

 Scarborough ; Flamborough j it has been taken in abundance in York Cemetery by 

 the late Archdeacon Hey ill a fungus, Coprinus comatus, a species usually found in 

 burying-grounds. 



The large size, subcylindrical form, and convex thorax will easily 

 distinguish this species. 



A* fumata, Er. (umbrina, Gyll., nee Er.). Elongate-oblong, rather 

 convex, shining, with somewhat coarse and scanty pubescence, fuscous- 

 black or brownish-red, lighter towards apex of elytra ; antennae very 

 short and stout, ferruginous, with fifth and seventh joints transverse ; 

 thorax scarcely transverse with sides slightly rounded, convex, rather 

 deeply and thickly punctured, base evenly and strongly margined ; elytra 

 evidently more coarsely, although not more deeply, punctured than 

 thorax; legs reddish-brown or reddish. L. 1| mm. 



By evening sweeping under fir trees ; also under bark of birch, &c. j rare ; Mickle- 

 ham (Champion) ; Caterham ; Bold records it from Gosforth and Gibside, North- 

 umberland district, as inhabiting a small yellow fungus which grows on decaying 

 stumps, and as not rare ; it is not, however, quite clear whether he is referring to this 

 species or to A. fimetarii ; in fact, the latter seems most probable. 



The species is easily distinguished from all the others by its short stout 

 antennae ; it somewhat resembles A. Barani, but is differently coloured 

 and much less closely punctured. 



A. Barani, Bris. Somewhat variable in colour, but usually dark 

 pitchy-brown or black with a distinct spot before apex ; light specimens, 

 however, occur with the suture and apex of elytra only darker, and inter- 

 mediate forms are found with a spot at the shoulder and an oblique livid 

 stain near the apex ; the doubtful forms may be distinguished from the 

 allied species by the close and at the same time strong punctuation of 

 the thorax ; the antennae are moderately long, ferruginous ; the thorax 

 is slightly transverse with the sides feebly rounded, convex ; the elytra 

 are evidently more depressed than in A. fumata, and are coarsely punc- 

 tured, the punctures being more diffuse and larger than those of thorax ; 

 legs testaceous. L. 1 mm. 



At roots of grass, in flood refuse, &c. ; only found in marshy places ; Eltham 

 (Sharp); Lee (Champion); Netting Hill, on edges of a pond (Power); it is not 

 uncommon where it occurs, but is very local.
