 clubs of tlie latter infuscate. Head iinpiinctate. Thorax 

 with It.s base sinuate on eithei' si.le and produced backwards 

 in the middle, with lateral margins (seen tVoin tlie side) 

 slif^iitly sinuate in the niiddle, hind ani;les nearly rii^ht 

 angles; with a strong basal series o£ rather elongate pnnc- 

 tures, becoming ol>solete at the sides, further removed from 

 the actual base in the midtlle than at the ends of the series 

 [it recalls the basil series ol: some speoies of AcritHs'^\ ; diss 

 l)earing a numlxM' of very fine sul)obsolcte punctures, but in 

 some lights and [)Ositions tliese are scarcely visible. Ehjtr i 

 of nearly the same length as their combined breadth, con- 

 siderably larger than the abdomen, the outline of which is 

 shown in fig. 40 appearing through the elytra as a dotted 

 line (perhaps some allowance must be made for shrinkage 

 of the abdomen) ; lateral tnargins not visible from directly 

 above; the elytra have no trace of a sutural stria, and are 

 finely and rather closely punctate; the punctures under a 

 high j)0wer appear as '(\\\q elongate dashes, closer at the 

 base and suture, and almost obsolete towards the apex (like 

 those on the thorax., the punctures in some lights and 

 asp.-cts are difficult to see owing to their shallowness). 

 Winqs ample. Metastervum (fig. 41) ver}' convex, im|)une- 

 tate in the niiddh;, finely |)nnctured at the sides, the diverging 

 .striai behind the iniddle coxie are punctured and run in a 

 continuous curve from the anterior to the lateral margins of 

 (he metasternum. Abdomen in several specimens tapering 

 t«i a blunt point, first segnient almost impunctate, each seg- 

 ment with a series of very fine short hairs, rather wide apart. 

 Front tibio' of J (fig. 42) slightly incurved towards the apex, 

 wiiii the inner apieal angle produced into a sharp iieel ; in 

 both J and ? (for the latter sex, see fig. 43) the excavation 

 of the outer margin towards the apex is conspicuous. No 

 oilier external .<exual distinction is visible. 



No species in Maithews's Collection resembles this at all 

 closely, and those desciibed since his time seem quite diffe- 

 rent. 0. japo)iicusj Mattli., has a basal thoiacic series of 

 pnnctnres, but they are ninch finer; it is much larger than 

 O. vtuniw, has a minutely reticulate surface, and much closer 

 elytral and thoracic punctuation.
