pubescence on the elytra and on the under side, and long greyish and black 
hairs on the head and prothorax ; antennal joints strongly serrate 
inwardly ; head and prothorax deeply scrobiculate punctate, the 
pubescence on both being longer and denser than in the other species ; 
prothorax as broad as long, ampliate rounded laterally at about the 
median part, triangularly attenuate thence to the apex, and bearing in the 
centre a longitudinal raised line ; elytra sub-cylindrical, slightly broader at 
the base than at the apex, deeply and closely punctate and not distinctly 
coriaceous ; under side aciculate ; spurs seemingly free near the base, 
diverging towards the apex, both of same length and thickness, and equally

ISELMA OKIEPANA, n. Sp. 
Black, with the legs and even the tarsi flavescent and the elytra pale 
flavous, covered with a greyish flavescent pubescence, black, however, and 
longer and erect on the head and prothorax ; antennae filiform ; head 
covered with deep, contiguous, equal punctures ; prothorax ovate not 
strongly attenuate in the anterior part, and covered with deep, closely set 
slightly irregularly disposed punctures separated by a narrow wall ; in 
addition to the black erect hairs there is also a fine flavescent sub- 
appressed pubescence which is also noticeable on the head, and in the 
centre of the convex disc is a longitudinal raised line obliterated at both 
ends ; elytra closely punctate, each puncture bearing a flavescent hair on 
the dorsal part adjoining the suture, and a black one laterally and behind ; 
under side closely aciculate, briefly pubescent ; hind spurs very long, 
either fused for the greatest part of the length, or free, the inner one 
obliquely truncate, much longer than the outer, and both sharp at tip. 
Distinguished from I. flavijoennis and I. namaqua by the more filiform 
antennae, the colour of the legs, the prothorax less attenuated in front, and 
the shape of the hind spurs. 
Length 7 mm. ; width 3 mm.
