joints '2 and 8 short, equal. Prothoiax very short, rapidly narrowed from the 

 base, the anterior angles prominent. Elytra explanate and sharply margined 

 at the sides, hollowed below the humeri, with faintly impressed lines on the 

 disc, the one along the suture the most distinct. Posterior coxae without 

 plate. [Posterior legs wanting.]

One specimen, in very good condition, except that the jjosterior legs 

 are wanting, as is often the ease amongst preserved examples of these 

 insects. The pallid elytral markings are very sharply defined. The 

 nearest ally known to me is perhaps the Indian O. ])icta F. 



13. — Or a hifoveifrons, n. sp. 



Oblong-oval, somewhat depressed, moderately shining, closely pubescent, 

 obscure testaceous ; very densely, minutely, the prothorax less distincth', punc- 

 tate. Head rather small, with a deep fovea on each side near the eyes ; antennae 

 slender, comparatively short, joint 3 small, barely as long as 2, 4 moderately 

 elongate. Prothorax rapidly narrowed from the base, the anterior angles pro- 

 minent. EWtra depressed along the suture anteriorly, with an indication of 

 raised lines on the disc, narrowly margined, the sides feebly rounded. Posterior 

 coxae without plate. Posterior legs long, the tibiae widened, curved, carinate, 

 the upper spur shorter than the first tarsal joint.

One specimen, received by the Museum in 1901. This insect has 



the general facies of a Cyplion, and is distinguishable amongst its allies 



by the very denseh', minutely punctured elytra, the bifoveate head, and 



the simple posterior coxae. It is just jwssible 0. hifoveifrons may be 



synonymous with the imperfectl}" described Scirtes doncJcieri Pic (1913), 



type from the Congo ; but this can only be ascei'tained when the two 



insects are compared.
