HETEROMERA. [BlapS. 



line, more prominent at anterior angles ; antennce with joints 4-7 

 oblong ; thorax scarcely transverse, narrowed behind ; elytra broadest in 

 middle ; metasternum transversely furrowed ; legs long ; allied to B. 

 mucronata, but distinguished by its narrower form, and by having the 

 thorax distinctly narrowed behind and the apical process of the elytra 

 longer. L. 18-20 mm. 



Male (female ? according to Thomson) with a fovea set with yellow 

 hairs at the base of the second abdominal ventral segment. 



Very rare, and somewhat doubtfully indigenous, as very many of the specimens 

 that have stood in our old collections under this name must be referred to the succeeding 

 species ; Burton-on-Trent, in Mr. Worthiugton's brewery ; recorded from Glanvilles 

 Wootton, Dorset, and as common in houses in Exeter ; but these records very pro- 

 bably must be referred to B. mucronata ; Scotland, very rare, in outhouses, Tay and 

 Moray districts ; in Dr. Power's collection there is a specimen from Elgin, and two 

 sent from Scotland by Mr. Hislop. 



B. mucronata, Latr. (oltusa, Sturm, teste H. E. W.; mortisaga, 

 Steph., Curt., 01., nee L. ; Leptocolena, mucronata, All.). Broader than the 

 preceding, obovate, upper surface dull, under surface more shining ; 

 clypeus with a central line, scarcely prominent at anterior angles ; 

 antennae with joints 4-7 elongate and the penultimate joints short oval ; 

 thorax a little broader than long, with sides- rounded and narrowed in 

 front, scarcely narrowed behind, finely, rather diffusely and obsoletely 

 punctured ; elytra broadest behind middle, very finely punctured and 

 somewhat coriaceous; metasternum transversely furrowed in middle; 

 apical process of elytra short; legs long L. 18-22 mm. 



In cellars, stables, kitchens, churchyards, &c. ; crawling about at night ; generally 

 distributed and common throughout the greater part of the kingdom ; Mr. Bold 

 remarks that it has been found in plenty in the Northumberland aud Durham 

 district down some of the deepest coal mines. 



B. similis, Latr. (fatidica, Thorns. ; obtusa, Curt., Thorns. ; Agroblaps 

 similis, Mots.). This species may at once be known from the two pre- 

 ceding by its broader form and by the structure of the antennae, which 

 are considerably shorter, and have joints 4-10 short oval and moniliform, 

 the seventh being larger and broader than those contiguous to it ; the 

 clypeus has no smooth central line, and is scarcely prominent at the 

 anterior angles ; the thorax is hardly transverse, and has the sides sub- 

 parallel and a little narrowed towards base ; the elytra are broad and 

 rather convex, widest about or a little behind middle, more plainly 

 punctured than in the preceding species ; metasternum with traces of a 

 transverse furrow at sides only ; sexual characters as in . mortisaga. 

 L. 18-22 mm. 



In cellars, outbuildings, &c. ; local and, as a rule, not common ; London ; Hert- 

 ford; Kingsgate, on the sea shore (T. Wood); Dover; Hastings; Brighton; Hamp- 

 shire; Weston-super.Mare | Cambridge; Scotland, in outhouses, rare, Solway 

 district.
