 10-14 mm.

Head and prothorax as in ^. omoj^lata ; elytra much more ampli- 

 ated behind from behind the subhumeral patch in the female, and 

 not quite so much convex in both sexes ; intervals vaguely punctato- 

 striate, and moderately convex from the base to two-thirds of the 

 length, the subhumeral patch broad, ovate, reaching from the third 

 to the seventh interval ; supra-marginal white band beginning only 

 at about the median part of the outer sides and reaching the apex. 



This variety is a good form of transition between omoplata and the 

 following Mellyi ; the intervals are less convex than in the first 

 species, and more so than in the second, the supra-marginal white 

 band is also shorter than in both, but in a female example from 

 the Middle Limpopo this band is as long as in Mellyi. Length 

 40-42 mm. ; width 13-15|- mm.

Head and prothorax of omoplata ; both sculptured alike ; elytra of 

 the same shape, but a little broader at the base and not so much 

 convex ; smooth, with hardly any striation ; on each side a broad 

 obovate subhumeral pale yellow patch consisting of three coalescing 

 elongated ones ; the supra-marginal band yellowish white, reaching 

 from the first third of the length to the apex. Length 31-41 mm. ; 

 width 10-15 mm.

Shape of head, prothorax, and elytra as in Mellyi, but the elytra are 

 distinctly and regularly striato-punctate ; the punctures are shallow 

 and the intervals quite plane and with a double series of shallow 

 punctures ; the supra-humeral patch is as broad as in Mellyi, and of 

 the same colour, but there is no supra-marginal posterior pubescent 

 band. 



I have seen one example only of this variety, a female, but I 

 do not think that the absence of the supra-marginal band is due 

 to an accident, because there is no trace on the eighth interval 

 of the depression and slight roughness that underlies the pubes- 

 cent patches or bands in the other varieties. Length 38 mm. ; 

 width 14 mm.
