254. MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NÍTIDULARLE. 
at the base than at the apex ; the sides also are scarcely at all sinuate, instead of being, 
as in C. Wallacei (more especially in the males), sinuate both before and behind the 
dilatation in the middle. The elytra, besides being more depressed, are more dilated and 
rounded on the sides, and have the surface marked by inequalities, which are well indi- 
cated by tufts of long woolly brownish pubescence; these are separated from each other 
by transverse depressed spaces, one behind the shoulder, one along the apex, and one 
between these, interrupted on the disk, and further by an elongated depression alongside 
the suture, and the basal elevation is further separated by two oblique longitudinal 
depressions parallel to the sides of the scutellum, but at some distance from them. 
It is rufous, with the antennse, elytra, and legs black. The basal article of the an- 
tenn:e, however, whieh is largely developed, has a thick tuft of reddish pubescence on 
the outer margin, and the last two united articles of the club, instead of being rufous as 
in the other species, are black, with a tinge of red on the last only. The punctuation on 
the head and thorax is much fainter than in the other species. The thorax is more 
equal on its surface; it has a semicircular depression behind the head, and another con- 
centrie semicircular depression near the base, both with the concave side towards the 
head. Both the thorax and seutellum are more pubescent than in the other species, and, 
as already mentioned, the elytra are much more so. "The elytra are considerably more 
thickly and closely punctate, and the excision at the exterior apical angle is more open. 
In the legs the base of the femora is reddish, and the thighs are not quite so thick as 
in C. Wallacei. 
Collected with the other species by Mr. Wallace in Sarawak. I have only seen one 
specimen since I detected the differences characteristic of the species, and that was in 
the collection of Mr. Fry, who has obligingly ceded his specimen to me; but I have no 
doubt that many more unrecognized examples of this species must be standing in collec- 
tions under the name of C. Wallacei, which have been sent home by Mr. Wallace mixed 
with that species, for I have vague recollections of examples with tufted pubescence on 
the elytra which did not attract my attention at the time, but which, on examination, 
will, I think, now be found to belong to this species.

Pascoe, in Journ, of Ent. i. 98 (1861). 
Valde affinis C. Wallacet; minor, minus nitidus, magis punctatus; antennis clava 
distincte triarticulata ; thorace lateribus minus angulatis, disco minus impresso; 
rufus, elytris nigris, pedibus rufis. Long. 3} lin., lat. 1 lin. 
Habitat in Borneo. 
A good species, although so much like C. Wallacei, that it might, if not carefully 
compared with it, be mistaken for a variety of that species. It possesses especial interest 
from the club of its antennze showing the usual number of articles free, and not the last 
two united as in the two other species, thus confirming my conclusion that they are 
3-jointed in these species. It is smaller than the smallest specimen of C. Wallace’ which 
I have seen. Depressed above, rufous, with the elytra black. The head very thickly 
punctate. Thorax hexagonal as in C. Wallacei, but the lateral angles not nearly 80 wide
