Physical descriptionAlthough this genus cannot be defined by means of the tuberosities at the side of the thorax, yet it may be satisfactorily separated from Eupagoderes by the absence of adhesive pubescence from the lobes of the third tarsal joint. The tips of the hind tibiæ are cavernous, as stated by Lacordaire, though in an imperfect and variable manner.
Ophryastes is peculiar to the arid regions of the Southern United States and Northern Mexico. The species are no doubt epigeal in habits, though I have not seen any records to this effect.
A very interesting North-American form may be at present placed in the genus, though, no doubt, it will have to be ultimately separated*.
