Sp. Necrophorus vespillo Fasr., Silpha vespillo L., Raseu Ins. tv. Tab. 1, 
PanzER Deutschl. Ins. Heft 2, Tab. 21 ; the grave-digger ; 6'’—8’” long, 
black, elytra with two orange-coloured transverse bands, the club of an- 
tenne brown. This beetle flies with elytra erect, the under-side turned 
outwards ; it diffuses a strong smell resembling musk. Like Geotrupes 
stercorarius and vernalis it is sometimes infested by small acari. The 
periods of larva and nymph together extend only to seven weeks. This 
species, like the others of this genus, feeds on dead animal substances. By 
an union of their forces these beetles dig away the ground from under the 
carcases of small animals, moles, mice, &c. and so bury them beneath it. 
They lay their eggs in the bodies thus interred, and the lary feed on them.
