once distinguisli it from all our allied species ; ihorax without pubescencp ; 

 abdomen with dark pubescence except at apex, which is furnished _ witli 

 a tuft of yellowish hairs, poftevior tibiae straight ; anterior tarsi dilated 

 in male ; the size is very variable, some specimens being very small. 

 L. 10-15 mm. 



lu carcases, decaying fungi, &c.; rather local in some districts, but^, as a rule, 

 comiiion and generally distributed in England and Scotland, and probal)ly in 

 Ireland. 



MT. vestig-ator, Hersch. Black, with two orange bands on the elytra ; 

 club of antennae orange-red : thorax considerably dilated in front, with 

 long yellow hairs on all the margins, Avhich are also present to a less 

 extent on the head; the abdomen and femora are also coveied with 

 yellow pubescence : it most closely resembles N. vegpil/o, but is easily 

 distinguished from that species by the straight posterior tibiae, and the 

 emarginate posterior trochanters which terminate in two short spines. 

 L. 16-18 mm. 



In carcases, &c.; not common; London district, Battersea Fields (Sf(pbcns), 

 Weybridge; Deal; Dawlisb, Devon; Cromer, Norfolk; not recorded from ti.e 

 northern districts of England, or from Scotland ; Irehmd, near Belfast (Haiiday). 



N. ruspator, Er. {bwestigcdor, Zett). Black, elytra with two 

 orange bands, the anterior of Avhich is not interruj)ted at suture, but is 

 continued in common across their Avliole breadth ; the black band between 

 the two is more regular and less dentate than in the other species ; 

 thorax without pubescence ; abdomen with scanty, dark pubesceiue, 

 except for a yellowish tuft of hair at the apex ; posterior tibiae straight_, 

 posterior trochanters emarginate at apex; male with the aiiterior taisi 

 strongly dilated, and furnished as in the allied species Avith yellow 

 brush-like hairs beneath, L. 15-18 mm. 



In carcases, &c. ; local; Shirley, Mickleham, Weybridge, Shipley near Horsham; 

 Hastings; Devon; common in the Midlands ; Manclle^ter and Liverpool districts; 

 Nortiinuiberland and Durham ; Scotland, couimou, Sohvay, Forth, Tay, and probably 

 other districts ; Ireland, near Dublin, Waterford, &c. 



V. Microcephalus, Thoms. This variety differs from the type in 

 having a very small more or less triangular head ; the apex of the pos- 

 terior trochanters, which are recurved in the type form, are straight, and 

 the clypeus is only feebly- emarginate ; the specimens appear to be males : 

 it has occurred at Weybridge and other localities. 



N. interruptus, Steith. {/ossor, Er.). This species is closely allied 

 to the preceding, but may be distinguished by having the anterior band 

 interrupted more or less broadly at suture, and by the distinct yellowish 

 or yellowish-grey pubescence of the abdomen ; the club of the antenna? is 

 orange-yellow, the thorax is not pubescent, and the posterior tibiae are 

 straight; the posterior trochanters are obscurely emarginate at apex. 

 L. 12-18 mm.
