Descriptive Catalogue of the Coleoptera of South Africa. 185 
occasionally impinging on the humeral part, the two bands are broad, or 
very broad, of nearly equal width, reaching from the sutural to the marginal 
fold, the hind border of the post-median band is slightly sinuate and 
occasionally moderately ampliated at about the median part, and is very 
narrowly brownish. 
Length 23|— 34 mm. ; width 9-12 mm. 
This species seems to be restricted to the southern part of the Cape 
Colony, and to Natal and Zululand ; above that limit it seems to be 
replaced by, or merges into, the variety vulgaris. 
Var. KAKAMAS, 
Plate XXIII., fig. 2. 
Shape, size, vestiture and livery of M. octdata, but easily distinguished 
by the deeper, coarser and scrobiculate punctures of the prothorax; the 
basal dorsal patch is reduced to a minute spot, and the lateral one to 
a mere dot; the two transverse bands are of nearly equal width throughout, 
very little sinuated, and both have the hind edge plainly brownish rufous. 
Length 28-32 mm. ; width 7f-9 mm. 
Hab. This variety seems restricted to the dry, arid parts of the north- 
western part of the Cape Colony. 
Var. VULGARIS, 
Plate XXIIL, fig. 3. 
Shape, size, and livery of M. octdata, differs from the latter by the 
more closely set and more regular punctures on the head and prothorax ; 
the large basal, dorsal patch on each elytron is reduced to a small yellow 
spot, and the lateral one to a dot, as in the var. kahamas, and the anterior 
transverse yellow band is as broad as in M. oculata with the borders 
hardly sinuate, the post-median band is transversely ampliate-ovate from 
the suture to about the median part, and continued thence to the outer 
margin as a slightly slanting band reduced to half the width of the median 
dorsal part; along the hind edge is a broad rufous brown border nearly half 
as broad as the yellow band at its widest part. 
Length 32 mm. ; width 11 mm. 
Hah. The whole eastern part of Cape Colony, Natal, Transvaal. 
Var. TRANSITORIA, 
Plate XXIII., fig. 4. 
Smaller than the var. vulgaris ; sculpture of head and prothorax 
identical ; on the elytra the basal dorsal and lateral spots are very small, 
the anterior band is however very broad, covering nearly half the length ;
