Scapliidium.'] CLAVICORNIA. 347 



rupted row of strong punctures at base ; scutellum conspicuous ; elytra 

 with the sutural stria strongly punctured and continued along base, the 

 rest of the upper surface moderately and not regularly punctured ; 

 abdomen partially exposed, strongly pointed ; legs long, black, with tarsi 

 pitchy. L. 5-6 mm. 



Male with the metasternum impressed in middle, and with the seventh 

 ventral segment of abdomen conspicuous. 



At the damp bottoms of wood-stacks, under logs, in fungoid growth, rotten 

 stumps, &c. ; not uncommon in the London and Southern districts; it is also found in 

 the Midlands at Gloucester, Bewdley, Cannock Chase, and Sherwood Forest, &c. ; 

 Yorkshire 3 Northumberland district, Gibside ; not recorded from Scotland. 



SCAPHISOMA, Leach. 



This genus contains about twenty small and inconspicuous species, 

 several of which are very closely allied to one another ; they are chiefly 

 found in Europe and the adjacent countries, and in North America, but 

 a few have been described from Ceylon, South Africa, &c. ; they may be 

 easily recognized by their long and slender capillary antennae, and by 

 having the scutellum hidden by the base of the thorax. 



I. Antennae with eighth joint very small, barely a third as 



large as the ninth joint S. AGARICINUM, L. 



II. Antennae with eighth joint at least half as large as the 



ninth joint. 

 i. Form broader ; elytra less thickly punctured ; seventh 



joint of antennae wider than apical joints S. BOLETI, Panz. 



ii. Form narrower; elytra more thickly punctured; 



seventh joint of antennae not wider than apical joints . S. ASSIMILE, JEr. 



S. ag-aricinum, L. Ovate, narrowed in front and behind, black 

 or pitchy-black, colour lighter in immature specimens, shining ; head pro- 

 duced, antennae testaceous, very slender and capillary with a feebly 

 marked 5-jointed club, first two joints thickened, eighth joint very small, 

 eyes not emarginate ; thorax rounded and narrowed from base to apex, 

 anterior angles not- produced, base with no larger impressions as in 

 Scaphidium scutellum hidden ; elytra rather distinctly but not closely 

 punctured,- usually lighter at apical margin, which is broadly truncate ; 

 legs long and slender, reddish- testaceous, tarsi elongate. L. 2 mm. 



In fungi, rotten wood, &c. ; not uncommon and widely distributed in the London 

 district, and in fact from the Midlands southwards ; Lincoln, common in Riseholme 

 Park ; Northumberland district ; not recorded from Scotland. 



S. boleti, Panz. Very like the preceding, but of a lighter colour, 

 and distinguished by having the eighth joint of the antennas distinctly 

 larger, and the antennas themselves brownish with lighter base ; the 

 thorax, moreover, is shorter and more contracted in front than in S. agra- 

 ricinum, and the elytra rather wider in the middle, with the sutural 

 striae more evident and the punctuation coarser and not quite so close ;
