although much less strongly than in the other species of T'rochalus, 
the median part of the anterior margin is also plainly angular, which 
is not the case in 7’. wrbanus, and as the outer angles are reflexed 
this anterior margin is therefore tri-dentate, there are no traces of a 
longitudinal keel; the anterior tibie are bi-dentate.

‘“‘ Sub-globose, ferruginous, sub-fuscous, and with a coppery sheen ; 
densely punctate ; elytra very obsoletely striate, the sutural stria not 
much impressed. 
Length 23-3 lin. ; 
More spherical than the preceding form (7. @rugineus), but not 
quite spherical; vivid brown, sometimes paler, sometimes darker, 
and with a strong bronze sheen, densely and finely punctate ; elytra 
very weakly striate, the sutural stria is more marked than the others; 
head with a high transverse ridge between the frontal part and the 
clypeus, the latter shghtly convex, more coarsely punctate; pygidium 
and under side with more scattered and coarse punctures.”’ 
I am inclined to consider this species as identical with the short, 
and therefore more convex, form of 7. @rugineus, which, as I have 
already mentioned, occurs also in Cape Colony. Burmeister’s 
example was collected by Ecklon. This collector did not, to my 
knowledge, collect Insects in Natal or the Transkei, until long after 
the publication of Burmeister’s book.

‘‘Globose, fuscous-black, pectus and legs piceous. Length 4 lin. 
Only one example from Tette. Shape and size of Byrrhus pilula. 
Belongs to the first section proposed by Burmeister for species with 
bi-dentate anterior tibie. The upper side is deep dark brown, 
almost black, and without sheen. Head and prothorax tolerably 
densely and elytra scarcely visibly punctured, the latter indistinctly 
striate. Under side and legs dark piceous-brown.”
