A. rhombeus, 0]. A large and conspicuous species, of a dark 
brown, ferruginous, or reddish-yellow colour, with the head and thorax 
sometimes darker, ‘clothed with rather long greyish pubescence ; head 
rather strongly punctured, forehead deeply impressed, antenne as long 
as head and thorax, ferruginous or rufous, serrate, last joint with con- 
tracted and conical apex; thorax rather flat, longer than broad, with 
sides subparallel, narrowed in front, posterior angles projecting, 
carinate, upper surface strongly punctured, sparingly on disc, thickly 
at sides; scutellum large and long, rather convex; elytra slightly 
broader than thorax, long, subparallel, very gradually narrowed to 
apex, with the pubescence in fresh specimens thicker behind middle, 
and more or less abraded, the smooth space presenting the appearance of 
an obscure V; the striw are rather deep, and the interstices slightly 
convex and not closely but distinctly punctured; legs reddish-testa- 
ceous. L. 16-18 mm. 
In decaying trees and logs; also by sweeping bracken; rare; Lea Wo d 
(Stephens) ; Lyndhurst and Brockenhurst, New Forest; Sherwood Forest ; Dunbain 
Park (Chappell) ; the only specimen I ever captured was taken about the last day 
of July 1877 in the New Forest on bracken.

strongly punctured, forehead depressed, antenne rather long, black, 
serrate, third joint much longer than second; thorax sinuate before 
posterior angles, which are carinate, finely punctured, more closely at 
sides than on disc, with traces of a central furrow often present; elytra 
rather broader than thorax, with sides very slightly rounded, and 
gently and gradually narrowed from posterior third to apex which is 
broad, strive fine and shallow, interstices more or less raised in middle,
