At times the horse laughter is even slightly flavored with the stercoraceous smell of the stable.

Black above, the Mimic Geotrupes is the colour of copper pyrites below; also black in all parts exposed to the light of day, the Stercoraceous Geotrupes displays a ventral surface of a glorious amethyst violet.

It becomes black on the dorsal surface of the Stercoraceous Geotrupes and the Mimic Geotrupes; and, with a quick change, it turns into amethyst under the belly of the first and into copper pyrites under the belly of the second.

But the dwarf undertaker does not on that account scorn stercoraceous fare: he feasts upon it like the other Onthophagi.

I evaporate a few drops of sulphuric ether in a glass jar and put in a Stercoraceous Geotrupes and a specimen of Buprestis tenebrionis, at the same time.
