edges sharply sinuate, and the post-median one is of the same size as the 
ante-median, and similarly scooped in the anterior edge.

Ceroctis karroensis, n. sp., 
Plate XXIV., fig. 72. 
Black, moderately shiny, clothed on the head and prothorax with a 
moderately dense, appressed greyish flavescent pubescence which is very 
short on the elytra, but a little longer there in the posterior than in the 
anterior part ; antennge black, very sharply serrate ; head and prothorax 
covered with unequal rugose, contiguous foveate punctures ; head with a con- 
spicuous median raised line ; elytra closely shagreened and having on each 
side a row of three dorsal yellow patches equi-distant from the suture and 
the median dorsal part and three corresponding ones on the outer margin. 
It is probable that both the second and third dorsal and marginal patches do 
occasionally meet, as they are somewhat sinuose, whereas the first basal 
dorsal patch is quite round. Under side and legs moderately pubescent. 
This species, of which I have seen only one example (^), is allied to 
M. horanella, but the 5-7 joints ( ^ ) are not so sharply serrate inwardly, 
and the two transverse bands of the elytra, if they united, would be much 
narrower than in M. horanella.

Black ; antennae black ; head, prothorax, and under side clothed with 
a short, dense, greyish flavescent pubescence ; prothorax closely and 
somewhat roughly shagreened ; elytra moderately shagreened, but with 
the black background more coarsely punctate than the coloured part ; on 
each elytron there extends a pale yellow very broad band reaching 
to past the median part from near the base, along which is a narrow 
border of the black background which descends also laterally below the 
humeral part ; this yellow band encloses a small black dot situated at 
about one-quarter of the length, and is deeply scooped twice on the 
hind margin which is separated only by a narrow interval from a reddish 
elongated patch extending from close along the suture to about one-third 
of the width without reaching the apex, strongly constricted at about the
