Corpus supra planum, rugosum, setosum; thorace in medio longi-

in dentem parvum corneum terminato. Palpi mazillares lon- 
gitudine mediocres, articulo 1mo minuto, 2do et 3tio sube- 
qualibus, 4to longiori elongato-ovali. Mentum oblongum,

This is a singular genus, which seems to partake of the cha- 
racters of the Trogide and Geotrupide almost in an equal de- 
gree. In general appearance it has almost the appearance of a 
small Z’rox, but is more flattened on the back, which is increased 
by the two lateral carine of the elytra. The antenne are also 
10-jointed, whereas they are 11-jointed in the majority of the 
Geotrupide. The labium has its two lobes exposed beyond the 
extremity of the mentum.
