eaeh side. Such speeimens from Motito are in the collection of Count Mniszech. Specimens from Damara Land
in the collection ofW. W. Saunders, Esq., are similarly marked ahove; but there is only a very small white spot
on each side of the metasternum, and a very minute one on each side of the fourth segment of the abdomen beneath.

The typical specimen of this insect is still preserved in the Banksian Collection at the British Museum.
The hind part of the head above has an irregular white mark ; the apex of the elytra are scarcely marked with
white ; the sides of the metasternum have an irregular white mark, and the abdominal segments have on each
side a row of spiracle-like white dots. I consider it most probably a rubbed specimen of Sji. plagosus.

The hind part of the clypeus is separated from the crown of the head by a transverse Hue, and the latter has
a raised central line, the lateral margins being also elevated. The pronotum is slightly margined, and very
thickly pimetnred at the sides, the disc being nearly destitute of punctures. The legs are punctured, as well as
the pygidium, which has a slight longitudinal carina. The body beneath is black and glossy, the middle of the
metastírnum smooth, with the sides punctured and irregularly covered with luteous patches ; the abdomen is
more sparingly punctured all over, the second segment has a small oval-oblong central impression, and is
marked, as well as the three following segments, on each side, with a pale transverse irregular patch. The
prosternai point is very short, but distinct. The head is represented laterally in pi. IX, fig. 5, which exhibits
the thickened aud truncated extremity of the mentum, clothed with setaj. The maxilla is represented in fig. 5 b,
and is identical in structure with that of C.filagosus, fig. 6 a. The mentum (fig. 5 c), however, is more regularly
oblong, ivith the sides nearly parallel, and the anterior portion more prominent and swollen. The anterior tibia'
are acutely bidentate, and the tarsi 5-jointed (fig. 5 d) and short.
The unique specimen of this elegant species is now preserved, with the remainder of the Westormann
eolleetion, in the Eoyal Museum of Copenhagen, to which it was bequeathed by its late possessor, liy whom it
had previously been kindly forivarded to me for description and representation in the present Monograph.

The South African species, upon which I have established this genus, agrees with Scaptobius in size and
«•eneral obscure appearance, but is distinguished at once from it by the form of the prothorax and mentum ;
fvom Ccenoehilus it differs in its broader form and unidentate galea of the maxilla!; from Cymophorus, in its
obscure appearance, comparatively smooth elytra, and rounded thorax; and from Oplostomus, in its bidentate
mando, form of the thorax, aud comparatively small mentum. It agrees with Centrognathns in several important
respects, but diH'ers in its small unarmed head and simple feet, Its nearest ally, however, seems to
be the Genus Pilinurgus, having nearly similar maxilla; and mentum, and bidentate anterior tibia?.

This insect has somewhat the appearance of a small depressed Trox (whence the generic name). The head
and prothorax are variolose-punctate, eaeh puncture producing a minute luteous bristle ; the elytra have
elongate punctures of the same character. The abdomen beneath in one sex is convex, but in the other the four
basal segments in the middle are flattened, but not channelled. In this sex the legs are rather longer, and the
spines of the fore tibife and the spurs of the four hind tibite are not so strong as in the female; the pygidium
has a longitudinal carina at its base, more strongly defined than in the female, and the elytra have several
obscurely defined abbreviated costse on the disc and towards the lateral margin.

The small size of the species of this African genus, and the tomentose covering of their upper surface,
without any of the deep sulci or raised curved costa; of the elytra, will distinguish them from their nearest allies.
I have here added a second species to this genus, closely allied to the type P. hirtus ; as well as a third species
from the East, which seems most fitly to be placed here, unless it should be considered more advisable to form
it into a separate genus, wliioh seems scarcely necessary.
