the joints of the antennge from the fourth to the last are broad, 

 compressed, dilated in the inner part and pubescent, while the three 

 basal are glabrous, and the third one as long as the two basal 

 ones ; the shape of the head is also very different, being very much 

 elongated in the anterior part, and very highly carinate from over 

 the eye to the outer angle of the base of the epistoma ; the labrum 

 is emarginate ; tarsi pubescent underneath. 



Besides the South African species, two more are recorded from 

 Africa, one from Zanzibar mainland, the other from Abyssinia,

Black, moderately shining, very briefly pubescent ; head very 

 long, labrum deeply emarginate, epistoma smooth, as is also a 

 triangular apical patch of the head, the rest including the apical 

 part of the neck, scrobiculate ; prothorax very narrow, one-third 

 longer than broad, hexagonal with the median angles acute, base 

 slightly notched laterally, produced behind, disk slightly convex, 

 deeply scrobiculate ; elytra ovate, very convex, almost gibbose, 

 deeply punctato-striate with the intervals raised, carinate and 

 smooth, but with a series of deep and broad lateral punctures, and 

 having on each side eight oblong yellow patches not broader than 

 the interval on which they are respectively placed, and arranged as 

 follows : two sub-basal ones on the eighth and ninth intervals, and 

 coalescing in the stria, and one on the fourth,, nearer to the median 

 part than the other two, one on the sixth at about the median part 

 of the disk, two nearly parallel on the fourth and sixth, at the top 

 of the posterior declivity, the outer one the smaller of the two, and 

 two more, a little lower down, on the seventh and eighth, the inner 

 patch the smaller of the two. Length 18 mm. ; width 7-J- mm.

 but obliquely truncate outwardly in the female, securiform in the 

 male ; antennae moderately long, pubescent with the exception of
