BiMA-CULATUS, Qyll., Erichson. 2| lin. Larger and much more 

 robust than either of the preceding. Dull black, antennae more or less 

 pitchy ; palpi testaceous yellow, with the apical joint fuscous, except 

 at the base. Head and thorax punctured more coarsely, and not so 

 closely as in the preceding species ; the former not so much hollowed 

 in front as impressed with two longitudinal grooves, leaving an intersti- 

 cial elevation. The fulvous spot on the elytra not comparatively large. 

 Abdomen stout, the punctuation getting faint towards the apex, and 

 with a very decided short longitudinal keel in the middle of the transverse 

 groove at the base of the first four segments. Legs testaceous, the 

 femora having the apex of a pitchy colour, which is suffused, especially 

 on the upper side ; the extreme tips of the tibiae and the entire tarsi 

 are also pitchy. Beneath black, the coxae pitchy black, and trochanters 

 pitchy-testaceous, and with a pointed tuft of bright yellow hairs between 

 the middle coxae. The meta-sternum rather indistinctly and coarsely 

 punctured. 



In the male the sixth segment beneath is deeply notched, with an 

 oblong tubercle near the middle of its base ; the fifth is widely emar- 

 ginate, with its middle surface depressed, smooth, and enclosed by two 

 parallel ridges which get more elevated towards the posterior margin, 

 and terminate on each side of the wide emargination in a prominent 

 truncate tooth. In the middle of this enclosure is an oblong tubercle, 

 and another, very minute, in the centre of the emargination. The 

 fourth segment has an oblong tubercle in the middle, from each side of 

 which the ridges so evident in the fifth segment seem to have their 

 origin. 



Common in Northumb., Dur., Cumb., Suffolk, and Derbyshire; 



also at Falkirk, in the fens, and at Preston. Abundant in London 



district.
