Scapliidium.'] clavicornia. 347 



nipted 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 consj)icuous. 



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

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

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

 Yorkshire ; Northumberland district, Gibsidc ; not recorded from Scotland. 



SCAPKXSOBZA, Leach. 



This genus contains about twenty small and inconspicuous species, 

 several of which are very closely allied to one another ; tliey 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. AnteuDse with eighth joint vei-j' small, barely a third as 



large as the ninth joint S. AGAKICINUM, L. 



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

 ninth joint. 

 j. Form broader ; elytra less thickly punctured ; seventh 



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



ii. Porm narrower ; elytra more thickly punctured ; 



seventh joint of antenuse not wider than apical joints . S. ASSIMIIE, Er. 



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 ajDex, 

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

 ScapMdium ,- 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 Riseholmo 

 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 antennae distinctly 

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

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

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

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