MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 255 
nor so angular, much more thickly punctate, subopaque, more equal on the surface of 
the disk, being without the waving inequalities and depressions upon it; the sides more 
strongly margined. Elytra much more thickly punctate, more flat and equal on the 
surface, black. Legs rufous. 
From Sarawak. Found by Mr. Wallace, along with the two preceding species, in the 
gum of a Dipterocarpus. 
Tribe II. CARPOPHILID AE. 
Carpophiline, Erichs. in Germ. Zeitschr. iv. 233 (1843). 
Maxille mala simplici. Labrum distinctum. Elytra abbreviata. Abdomen segmentis duobus vel tribus 
ultimis liberis. 
The most easily seized character of this tribe is the short elytra, leaving two or more 
segments of the abdomen exposed,—a structure which distinguishes it from all the rest 
of the family except the Brachypteride ; and from them they are separated by the single 
lobe of the maxille. As that, however, is an organ which it requires a dissection of 
the mouth to discover, some other more easily observed character is desirable; and an 
approach to such, although not one which can be laid down as without exception, will 
be found in the presence of antennal grooves in the Carpophilide and their absence in 
the Brachypteride, and in the club of the antennze, which in the Brachypteride is gra- 
dually elongate and approaching to the form of Hercules's club, while in the Carpophilide 
it is ovate or rounded and abrupt. 
A large number of this tribe are found upon flowers; others, whose flat depressed 
form well corresponds with the locality, under bark; one in bees’ nests; and a good 
many in decaying fruits. 
Head with mouth projecting. Antenne inserted on each side at the base of the pro- 
jecting clypeus, short, with the club large, oval, or round. Antennal grooves usually 
present, and converging; they are absent in Mystrops. Labrum bilobed. The mandibles 
are strong, and usually terminate in a sharp point, behind which lies a second smaller 
tooth, and behind that again a slight serration, generally effaced; but this is not absolutely 
constant: in Mystrops the mandible has no teeth at all, only a sharp point; in Cilleus 
it has numerous teeth; and the degree of prominence of the second tooth when it is 
present is very variable. At the base of the exterior of the mandible is a rounded 
condyle. The maxille are moderately broad, thin, and furnished with a close comb of 
hairs on the interior side.. The maxillary palpi are variable in form, the terminal article 
usually largest. The ligula is corneous in the middle, with transparent lobes on each 
side, varying in form in the different genera and even in the different species, but 
usually extending obliquely forwards and outwards in a sort of elliptical wing-shape. 
The posterior apex of the prosternum blunt and obtuse, resting slightly on the meso-- 
sternum. The abdomen is sometimes convex, at others very much depressed. The 
breadth of the abdominal segments is variable in different genera, the pygidium being 
the largest: in some genera it has a fimbria, broad at the anterior margin, narrow
