becoming finer at the base; the hxteral impressions shallow. Scutellum 

 perfectly smooth, triangular. Elytra broader than the thorax and 

 nearly twice its length, slightly expanded backwards, with truncate 

 apices; they are depressed alongside the suture, which, therefore, 

 seems elevated nearly to the base; there is also a transverse impression 

 before the middle ; their sculpture is like that of the thorax, but not 

 quite as coarse and more distant. Hind-body not quite the length or 

 brepdth of the elytra, broadly margined, rather fiinely punctate. 



Antennae rather longer than tlie head and thorax, with fine elongate 

 setae; basal joint stout and nearly the length of the 2nd and 3rd com- 

 bined, ith and 5th evidently longer tJian broad, joints 6-10 moderately 

 dilated and subquadrate, the terminal longer than the tenth. 



This, on account of the elevated suture, must be placed next to 

 O. hilarum. Sharp's 0. sagoloide, found at Picton, cannot be very 

 similar, as in its description there is no allusion to the elytral suture. 

 The 4th and 5th antenna! joints are rather longer and more obconical 

 than those of 0. hilar uw .

Elongate, subdepressed, nitid, finely and indistinctly punctate; 

 head, thorax, and base of elytra rufous, their hinder portion bright 

 fulvous; the legs, antennae, and palpi f ulvescent ; pubescence yellow, 

 elongate, scanty in front, thicker behind, where there are also some 

 long, outstanding hairs. 



Head, including the prominent rotundate eyes, as broad as the 

 thorax, obli(|uely narrowed anteriorly, its hind angles somewhat deflexed 

 and rounded; the median furrow widest between the eyes, prolonged 

 nearly to the base, but linear between the flattened antennal tubercles; 

 occipital foveae rather small and subangular. Thorax of equal length 

 and breadth, rounded and widest at or just before the middle; basal 

 impression large and subquadrate, lateral foveae deep at the base and 

 prolonged forwards beyond the middle, the base bipunctate. Elytra 

 a third longer than the thorax; their sides, behind the middle, some- 

 what curved and broader than elsewhere; sutural striae deep, the dorsal 

 ones abbreviated and not entire, being composed of a punctiform basal 

 and more elongated hinder impression; Ijetween the striae, on each 

 elytron, there is a distinct puncture. Hind-body as large as the elytra, 

 its first visible segment slightly shorter than the 2nd or 3rd, depressed 

 and bearing minute brassy scales at its base; the penultimate and 

 terminal together are broadly conical. 



Femora stout, narrowed towards the extremity; anterior tibiae mode- 

 rately and evenly curved externally, the middle pair rather less so, 

 the posterior strongly curvedly dilated near the middle, straight in- 

 wai-dly; terminal joint of the hind tarsi very large, gradually incras- 

 sate, subtruncate at apex, and just between the base of the claws provided 

 with a short process; the postei'ior claws unequal, enormously developed, 

 strongly arched above, the frontal thickened or mai-ginated above for 

 half its lengtli, semitransparent, thin, and nearly straight below, bent 

 and acute at the extiemity. tlie other equally long but not as thick from 

 above downwards.
