Reservoir and Markfield, Leicestershire (Power) ; Cannock Chase (Blatch) ; Scot- 
land, rare, Solway, Clyde, Tay, and Moray districts (Sharp, Champion, and others). 
IM. dispar, Germ. (neglectus, Muls.). Pitchy black, shiny, with the 
mouth and base of antenne, and the apex of abdomen and the margins 
of the ventral segments, yellow ; elytra with apex sulphureous yellow ; 
head without eyes a little narrower than thorax; antenne rather stout, 
reaching in male somewhat beyond apex of elytra; thorax a little 
broader than long, unicolorous black, shining, anterior margin straight 
in middle and obliquely eut off on each side, searcely margined in 
middle of sides;* anterior angles blunt, projecting, posterior angles 
right angles; elytra about two and a half times as long as together 
broad, irregularly and obsoletely and rugosely punctured ; legs yellowish 
with femora usually darker. L. 4-45 mm. 
Male with the head broader than in female, constricted behind ; the 
last dorsal segment short, the penultimate produced into a tooth on 
each side, the antepenultimate furnished on each side with a long pro- 
cess which is hooked at apex; penultimate ventral segment deeply 
emarginate at apex, the last forming a long style, which projects 
beyond the last dorsal segment, and is angularly curved in the middle, 
channelled to base, and narrowly incised at apex. 
Female with the head narrower, with the temples swollen. 
By beating and sweeping in and near woods; local; London district, rare, 
Mickleham, Woking, Weybridge, Darenth, Hammersmith; Hastings; New Forest ; 
Thornton Reservoir, Leicestershire; Repton ; York; Whalley Range, Lancashire ;

* Thomson says of this species, ‘‘ Prothorax lateribus immarginatis;” whereas 
Kiesenwetter says, ‘Es ist ringsherum, am deutlichsten an den Vorderecken 
gerandet.’’? ‘This instance will serve to show the difficulty of tabulating the species 
by externally apparent differences
