We are acquainted with two species of this genus, O. affinis ^HNS and O. maxillaris ^HNS, both of which agree in every respect with Latreille's chelifera ^HNS, with the exception of the sculpture of the abdomen. Latreille describes the abdomen as having the skin (or surface) very finely striated; we are acquainted with twelve species of the genus, none of which have the slightest trace of striation on the abdomen. Is it not possible that there is an error in the description of chelifera ^HNS, and that either affinis ^HNS or maxillaris ^HNS are identical with it?
