This Hpccie.s may readily he distinguished from the preceding by its somewhat larger 

 size; by the smaller size of the conical processes representing the parietal riflges, which are 

 oblique instead of transverse ; and by the shai)e of the clypeus, which is procurved instead of 

 straight.

P. rrc/ifoniia is the smallest species of its gcnns known to nie. The antennal lamellae 

 are short. The clypeus is strongly procurved. The frontal ridges are obsoh-te, but the 

 central tubercle, which is directecl forwar«l, is very strongly developed, the apex being free. 

 Apart from some of these characters, and the smoothness of the mctustcrnum 

 characteri.Htic of the genus, /'. rfc/icorMi* closely resembles the obove described species of 

 the genus (hlroulex. The mesothfirncie episteniB are. however, less extensively puncttireil 

 and uniformlv glos^v, .md the pro.stemiim is truncate l>ehind. The punctures round the 

 sears on the pronotum are usually more numerous ««ven than in O. siihrrrhcornif.
