covered with a very short but dense light flavescent pubescence; the 

 clypeus is more closely scabrose than the frontal part, the clypeal 

 ridge reaches from one gena to the other, but curves slightly back- 

 wards there, and is connected partly but not completely not by a 

 raised fold but by a smooth line, having somewhat the appearance of 

 a ridge, with the carina on the vertex, which is much raised, and 

 occasionally sub-denticulate in the centre, slopes slightly towards 

 the sides, and reaches from side to side a long way behind the eyes ; 

 the asperous granules of the prothorax are almost contiguous on the 

 whole surface, thus differentiating this species from 0. insignia, the 

 granules of which are also larger, and from 0. leucopygus, which is 

 only distinctly granulose asperous in the central part ; the elytra are 

 pale straw colour with the suture, and occasionally two narrow strips 

 on each side of the disk, light bronze; the punctures are somewhat 

 closely set, the second, third, and fourth intervals have three series 

 reaching from the base to about one-quarter of the length, and 

 sometimes farther down ; the pygidium is as broadly punctate as 

 in 0. insignis, but the punctures are more asperous, and the 

 pubescence, which is much less dense than in 0. leucopygus, is 

 somewhat flavescent. 



Length 7-8i mm., width 3^-5 mm.

" Sub-opaque, head and prothorax obscurely greenish bronze, 

 clothed with pale hairs ; elytra totally testaceous and very briefly 

 nigro setose; pygidium obscurely green-bronze, and with long but 

 sparse white flavescent hairs ; head granulate rugose, clypeus 

 rounded, frontal part arcuately carinate, vertex with a long carina 

 slightly arcuate, and situated between the posterior margins of the 

 eyes; prothorax very finely and very densely granulate, but less so 

 in the anterior part and towards the sides; it is abruptly declivous 

 and smooth on each side near the posterior angles and has in the 

 eentre of the anterior part a not very distinct transverse tubercle ; the 

 back is not longitudinally sulcate, and the sides are strongly sinuate 

 behind ; base marginate ; elytra minutely striate, intervals plane, 

 verj closely but finely punctate, the punctures simple; pygidium 

 with close asperous punctures. 



I length 8 mm.

Evidently closely allied to 0. albipodex and 0. leucopygus.
