ISELMA HIBSUTA, Thunb., 
Dissert, nov. spec. Insect., vi., 1789, p. 107; Haag-Eut., Deutsch. Entom. 
Zeitschr., 1879, p. 404. 
Closely allied to what I take to be I. ursus, Thunb., but easily dis- 
tinguished from the latter by the elytra being attenuate behind towards 
the apex. It is completely black and also densely hairy, the hairs on the 
head and prothorax being erect and very long, but the punctures although 
equally deep are less rugose, owing to the narrow wall separating them 
being less raised, the median raised line is wanting, there is a not very 
distinct elongated impression on each side of the central discoidal part, 
and the punctures of the elytra are finer but equally closely set. In my 
examples of I. ursus the hind spurs are somewhat short and straight ; 
whereas in this species they are sub-contiguous at the base, divaricating, 
and oblique towards the apex which is sharp. 
Length 9-11 mm. ; width 3-3^ mm.

ISELMA RUFIPENNIS, Haag-Eut., 
Deutsch. Entom. Zeitschr., 1879, p. 406. 
crihraria, Pering., Trans. S. Afric. Phil. Soc, iv., 1888, p. 142. 
Black, clothed with a long, dense black pubescence longer and erect 
on the head and prothorax, elytra purplish red with a somewhat fuscous 
broad sutural band ; antennae long, sub-serrate inwardly ; head covered 
all over with round, deep, somewhat irregular punctures separated by 
a narrow, slightly raised interval ; prothorax elongate ovate, greatly 
attenuated in front, covered with deep foveolate punctures, impressed on 
each side of the hind part of the disk, and having in the centre a plainly 
carinulate longitudinal line reaching neither apex nor base ; elytra sub- 
cylindrical, not ampliated behind, closely coriaceous shagreened, briefly 
pubescent except at the base and along the sutural part where the hairs 
are erect ; under side closely aciculate ; hind spurs soldered at the base, 
cleft from about the median part of the length, the two points of equal 
length. 
Males captured in September flying round a bush (JRhus) not in flower. 
Length 11-14 mm. ; width 4-4|- mm.

ISELMA BRUNNEIPES, Haag-Eut.,

Allied to the preceding species ; the shape is the same ; the colour is 
black with the elytra red or slightly purplish red all over ; the antennae
