Of other species Avith tAvo long and more or less erect interocular horns in 

 the male it is distinguished (apart from other features) by having much larger 

 eyes than 0. fweedensis, 0. australis, 0. anisocerus, and 0. mastersi; 0. pici- 

 pennh has a strongly elcA^ated ridge between the horns, and very different 

 prothorax, 0. fitzroyoisis is considerably smaller, more metallic, with the ])ro- 

 thorax as Avell as the elytra shagreened, and Avith someAvhat larger punctures ; the 

 other species are all vei-y much smaller. The largest female is almost entirely of 

 a dingy reddish-broAvn.

 blackish), tips of paljii, and tarsi of a more or less dingy red. ITnder-surface and 

 legs Avith long, Avhitish hair.

 punctures. Clypeus Avith sides moderately elcA^ated, middle more strongly 

 elevated and deeply notched; suture distinct on sides but not traceable across 

 middle. Eyes \^ery narroAv, Avith distinct facets. Prothorax Avith sides strongly 

 rounded, front angles strongly produced and subacute, margins narroAV on sides, 

 still narroAver at base and apex ; apical third retiLse ; median line scarcely indi- 

 cated ; Avitli croAvded, sharply defined punctures, of moderate size and occasionally 

 confluent. Elytra Avith narroAV, shining, geminate striae, containing small, 

 distant punctures; interstices shagreened, opaque, and Avith sparse, minute 

 punctures. Metasternum Avilh crowded, asperate punctures on sides, becoming 

 larger and sparser about coxae, and minute in middle. Abdomen Avith apical 

 segment strongly narroAved to middle ; pygidium shagreened and opaque. Length,
