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 
carine 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 
tibiz bi-dentate, tarsi very long, upper claw of the anterior ones 
slender, but nearly as long as the lower. 
Female unknown.

Testaceous, but also often chestnut-brown, and with the antenne 
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. mediocris, 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 O. ovatula, and if, as I strongly 
suspect, the male has 10-jointed antenne, it will be found to be 
closely allied to my S. mediocris, in which, like in 5. natalensis, the 
antenne are 10-jointed in both sexes, and the males of which have 
such very dissimilar genital clasps.
