Descriptive Catalogue of the Coleoj^tera of South Africa. 231 
the type form (fig. 109), invades the greatest part of the surface, the suture 
is narrowly black from the scutellum to about one-fourth of the length 
where it expands into a quadrate black patch extending on each side, and 
at about the middle is a small, sub-triangular dot ; on the humeral part is 
a long black band slightly broader at apex than at base and reaching from 
there to one-fourth of the length ; at about the median part is a sub- 
quadrate black dorsal patch, and the apical part is also black, the lower 
edge of the yellow part being there denticulate and sinuate ; the supra- 
apical flavescent patch is somewhat reduced. 
Length 14-16 mm. ; width 5J— 6J mm. 
Hab. Cape Colony (Ceres, Stellenbosch, Worcester). 
The normal form (fig. 110), which is the rarer of the two, has on each 
elytron a basal dorsal comma-shape patch and a lateral band connected 
along the margin with the anterior transverse band which is triangularly 
dilated along the margin, strangulated in the centre, irregularly dilated 
along the suture and sending close to it a hind spur which does not reach 
the posterior band, the latter is slightly broader and shaped in the same 
manner, viz., the anterior border is incised in the centre, the posterior is 
straighter along the suture and narrowly bi-incised thence to the outer 
margin. 
Length 14-17 mm. ; width mm. 
Hab. Cape Colony (Cape Town, Stellenbosch, Malmesbury). 
Var. iNSOLiTA, 
Plate XXIV., fig. 111. 
Size, shape, and colouration of D. africana ; the pubescence on the 
head and prothorax is, however, more flavescent, and the punctuation of 
the prothorax is not so deep and is slightly more irregular ; there is on 
each side a somewhat large basal dorsal patch the inner edge of which 
reaches close to the suture, the patch itself being slightly slanting towards 
it, the lateral patch is narrow but as long as the dorsal, the anterior 
yellow band which, like the post -median one, reaches from the suture to 
the outer margin without any connection along the margin is somewhat 
broadly scooped in the centre of the border, the hind one is 3-incised 
and emits near the centre of the disk a spur which occasionally reaches 
as a narrow streak the post-median band which is not broader than the 
anterior, and is as deeply but more narrowly scooped in the centre of the 
anterior border, while the strongly bi-sinuate hind border emits a central, 
elongate rounded lobe. 
Length 12-15 mm. ; width 5-6 mm. 
Hab. Cape Colony (Kimberley).
