middle, and very short, covered with shallow foveate punctures, 

 the clypeal carina is sharp and not much arcuate, the basal one is 

 fairly distinct and slightly arcuate, the space between the two 

 carinas is filled with sub-scabrose, irregular foveolate punctures, and 

 the basal part is impunctate ; in the male the antennal club is not 

 longer than the pedicel, and the third joint is as long as the other 

 two following, which are not very angular inwardly ; prothorax 

 short and broad, not much ampliated laterally in the median part 

 and very little attenuate thence to the basal angle, covered with 

 cicatricose punctures separated by narrow, somewhat sharp walls on 

 the sides, and a little wider and not quite so closely set in the 

 median and basal discoidal parts, there is no smooth transverse fold 

 above the base ; scutellum with two series of punctures ; elytra 

 sinuate laterally a little above the median part, deeply and closely 

 punctured with the punctures equal in size and separated from each 

 other by a space narrower than their own diameter ; pygidium 

 covered with deep, round, nearly contiguous punctures divided by 

 a narrow wall ; abdominal segments and metasternum covered with 

 deep, closely set punctures ; pectus hardly pubescent ; penultimate 

 abdominal segment not wider than the one preceding ; anterior 

 tibiae bi-dentate, tarsi very long, upper claw of the anterior ones 

 slender, but nearly as long as the lower.

Testaceous, but also ofteu chestnut-brown, and with the antennae 

 rusty-brown ; the female of this species, of which I have seen a 

 long series from several localities, is far from rare, but the male is 

 unknown. It is so closely allied to Schizonycha natalensis 2 , as 

 well as to S. mcdiocris, that but for the number of antennal joints 

 the three might easily be mistaken for one species ; the shape is the 

 same, but the punctures on the prothorax are deeper and more closely 

 set than in Schizonycha natalensis, and whereas in that species the 

 discoidal part has no median smooth area, there is a very plain, 

 longitudinal smooth band in 0. ovatula, and if, as I strongly 

 suspect, the male has 10-jointed antennae, it will be found to be 

 closely allied to my S. mcdiocris, in which, like in S. natalensis, the 

 antennae are 10-jointed in both sexes, and the males of which have 

 such very dissimilar genital clasps.
