and prothorax sub-scrobiculate punctate, the punctures deep, the latter is 
amphate ovate, only moderately attenuate in front, slightly bi-impressed 
on the disk, and having sometimes there a third, median impression ; 
elytra sub-parallel, closely shagreened punctate ; under side aciculate ; 
hind spurs fairly long, of equal length and obliquely acuminated from 
about the median part to the tip. 
This species is easily distinguished from the other species of the genus, 
except I. planidorsis, by its metallic colour ; and from the last-named 
species, which is also metallic, by the non-depressed elytra. 
Length 7-9J mm. ; width 2J-3 mm. 
Hah. Cape Colony (Clanwilliam, Worcester). 
ISELMA BOSCHIMANA, U. Sp. 
Black, with the elytra purplish red ; upper and under sides clothed with 
black pubescence not mixed with greyish or flavescent hairs ; antennae 
not sub-serrate ; head and prothorax clothed with long, erect black hairs, 
and both covered with round, not rugose punctures not contiguous but 
nearly so ; the prothorax is ampliate ovate but very distinctly attenuated 
in the anterior part, there is an impression on each side of the convex part 
of the disk, and occasionally a somewhat faint central one ; elytra 
elongated, sub-cylindrical, coriaceous shagreened ; hind spurs joined from 
the base to about the median part, both acute, inner one longer than 
the outer. 
Length 7-9 mm. ; width 2|-3 mm. 
Hah. Cape Colony (Clanwilliam).

Shape and size of I. hoschimana ; black, the elytra red with a slight 
tinge of brown ; the pubescence, especially on the elytra, is plainly 
flavescent ; the erect black setulose hairs on the head and prothorax are 
mixed with greyish flavescent ones ; the prothorax is quite globose and 
covered with small round punctures almost contiguous but separated from 
each other by a thin wall ; the elytra are elongated, sub-cylindrical, deeply 
and closely punctate, not coriaceous ; inner spur of hind tibiae much 
longer than the outer, and sharp. 
This species is closely allied to I. hoschimana, and also to I.palliclipennis, 
it differs from the former in the punctures of the prothorax, being 
narrower and more shallow ; in I. pallidipennis the punctaation is finely 
aciculate.
