are also sub-serrate ; the head and prothorax are covered with long, black, 
erect hairs, and the head is closely and irregularly punctured; the 
prothorax however is slightly less ampliate ovate, the punctuation differs 
in being more regular and less rugose, the lateral discoidal impressions 
are indistinct, and so is the longitudinal raised line, which, when 
sufficiently distinct, is reduced to a mere streak ; the elytra are slightly 
less coriaceous shagreened ; the hind spurs are soldered at the base, cleft 
from about the median part, the inner point is slightly longer than the 
outer and stouter. 
Length llj— 13f mm. ; width 4-4| mm. 
Hah. Cape Colony (Namaqualand). 
ISELMA FLAVIPENNIS, Haag-Eut., 
Deutsch. Entom. Zeitschr., 1879, p. 404 
Black, with the elytra light flavescent testaceous, almost straw-colour ; 
clothed with black hairs longer and more erect on the head and prothorax, 
and also very abundant on the elytra ; intermediate antennal joints not 
sub-serrate, but slightly angular inwardly at apex ; head closely and 
roughly punctate on the frontal part, and more finely and regularly so on 
the vertex ; prothorax elongate ovate, slightly less attenuated in front 
than the preceding species, scrobiculate, very convex and having in the 
centre a not always very distinct impression ; elytra moderately ampliate 
laterally in the posterior part, very closely punctate, but not distinctly 
coriaceous or shagreened ; under side closely punctulate ; hind spurs 
scooped at apex, the inner angle thicker and slightly longer than the 
outer. 
Length 10-12f mm. ; width 4f-5^ mm. 
Hah. Cape Colony (Namaqualand, Specktakel). 
My examples were compared with Haag-Eutenberg's type. 
ISELMA NAMAQUA, U. Sp. 
This species might at first sight be mistaken for I. ftavipennis, of w^hich 
it has the colour and shape, being likewise black with the elytra very pale 
testaceous, and clothed with black hairs ; the difference however is in the 
sculpture of the prothorax which instead of being scrobiculate is covered 
with round, moderately deep punctures without highly raised walls, the 
median impression is distinct, and there is in front and behind this 
impression a slightly raised longitudinal line ; elytra very closely punctate 
and somewhat coriaceous laterally ; hind spurs soldered, cleft at the tip, 
the two spines sharp and of equal width and length. 
Length 14-16|- mm. ; width 5-6 mm. 
Hah. Cape Colony (Namaqualand).
