and parts of legs reddish, club deeply infuscated. Tinder-surface and legs 

 moderately clothed. 



Head with interocular ridge very feeble and arched slightly backwards; 

 between it and base with very minute punctures, between it and clypeus with 

 fairly dense and sharph' defined ])ut rather small ones. Clypeus large, sides 

 moderately elevated, apex slightly more elevated and almost truncated ; punctures 

 somewhat larger and more crowded on sides than elsewhere; suture in three parts, 

 the median distinctly carinated, arched slightly forwards, and about three-fifths 

 of total, side parts less distinctly carinated, and oblique. Eyes narrow and with 

 distinct facets. Prothorax large, somewhat gibbous in front, sides strongly 

 rounded, front angles produced slightly outwards, lateral margins and gutters 

 moderate, apical ones slight, base almost immarginate ; punctures of moderate 

 size and sharply defined, although not deep, smaller and sparser about apex than 

 elsewhere; lateral foveae fairly large and deep; median line very faint, but trace- 

 able almost throughout. Elytra with narrow shining striae, containing small, 

 distant punctures; interstices shagreened, subopaque, feel)ly separately convex, 

 and with very small punctures. Metasternum with irregularly distributed punc- 

 tures, becoming sparse and small in middle. Abdomen with apical segment 

 strongly narrowed in middle ; pygidium with fairly dense but rather shallow 

 punctures. Length, 8 mm. 



Ilab. Queensland: Bowen (Aug. Simson). Type, I. 15404. 



At first glance approaching some forms of 0. consentaneiis, but interocular 

 ridge arched backwards instead of forwards, the space between it and clypeus, 

 and the clypeus itself, considerably longer ; in general it is extremely close to a 

 female placed (apparently correctly so) with 0. mastersi by Blackburn, but the 

 clypeus is more elevated in front and the abdomen of the type is distinctly 

 masculine ; 0. promptus and 0. margaretensis are more metallic, and have the 

 intercarinal space on head, and the clypeus considerably shorter. The elytral 

 striae have the appearance as of bearing stitches at regular intervals.

6 Black, shining, head and prothorax with a slight bronzy gloss, antennae, 

 palpi, and tarsi reddish, club flavous. IJnder-surface and legs with rather sparse 

 clothing, but becoming dense on sides of sterna and parts of front legs. 



Head wide, sides from near base almost semicircular, flat between eyes, 

 except for short remnants of an interocular ridge ; sides in front of eyes with a 

 few punctures, but otherwise almost impunctate behind clypeus. Ch^peus 

 moderately elevated on sides, more strongly in front : with dense and fairly large
