A widespread and well known species; the following diagnosis 

 will enable it to be identified : — 



Elongate, parallel, subcylindrical. Black, shining; legs piceous. 

 Head smooth, lateral margin sloping obliquely and evenly forward 

 from a little before the eyes: clypeus not divided from front; median 

 part truncate; wings strongly advanced, rounded at apex; facial 

 sulci lightly impressed; eyes prominent, lightly enclosed behind. 

 Mandibles short. Antennse not short, submoniliform, lightly 

 compressed. Labrum 5-setose. Prothorax subquadrate (4 x 4-1 

 mm.), lightly convex, narrowed anteriorly (ant. width 3-3 mm.), 

 declivous to base; anterior margin very lightly emarginate. 

 Elytra a little wider than prothorax (9-5 x 4 -.5 mm.), parallel; 

 strife crenulate, strongly imj^ressed near base, Ijecoming lighter 

 towards apex and sides, fourth outturned and joining fifth at base; 

 seventh interstice carinate at humeral angle, eighth very narrowly 

 and lightly indicated (sometimes obsolete) near apex. Prosternum 

 protuberant; intercoxal part very wide anteriorly, bordered on 

 each side by a strong wide carina, vertical and non-sulcate on 

 base; episterna covered with a faint wavy rugulosity. Lateral 

 cavities of peduncle punctate. Metasternum longer between 

 intermediate and posterior coxie than length of_^ posteriorjcoxfe; 

 episterna elongate. Anterior femora thick, not channelled below
