340 MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 
projecting tooth on each side. Labrum elongate, membranaceous, projecting, covered 
entirely with long hairs, bilobed, divided straight up the middle, the exterior margins 
sloping obliquely outwards and backwards. Antennz rather longer than the head; first 
article not thick, but nearly as long as the seven following articles taken together; 
second article rather long, but much shorter than the first; third article longer than the 
second; fourth article also rather long, but shorter than the second; fifth, sixth, and 
seventh articles short, small, and nearly of the same size; eighth broader; ninth, tenth, 
and eleventh forming the club, which is flat and round. Antennal grooves very well 
marked, convergent. Mandibles large, thick, coarse, strongly punctate, slightly bent in 
an elbow on the outside, bicuspid at the apex, and with a rounded tooth or projection, 
and a fringed plate or beard behind it, on the inner side. Maxille large, thickly bearded 
at the apex and on the inner side*. Maxillary palpi slender, subcylindrical, with the 
first article small, the second and third rather long, the second longer than the third, and 
the fourth elongato-fusiform and as long as the second and third taken together. Ligula 
corneous, with two large, subovate, transparent, membranous lobes. Labial palpi slender, 
cylindrical, first article minute, second and third nearly equal in length. Mentum broad, 
with a double margin (Pl. XXXVI. fig. 1e), both margins broadly emarginate. Pro- 
thorax subeylindrieal. Scutellum rounded at the apex. Elytra not striated, irregularly 
punctate, subquadrate, subcylindrical. Abdomen somewhat convex, with the last two 
segments exposed above; below, the second and third segments shortest and nearly 
equal, first and fourth nearly equal, last longest; fimbriz scarcely present. Metathorax 
without axillary pieces. Legs stout. Tibiæ expanded on the inner side towards the 
apex, and there parallel to the outer side and thickly clothed with strong hairs. Tarsi 
much dilated, and thickly clothed with hairs. Claws simple and short. 
The insect on which this genus is founded, although possessing characters too peculiar 
to allow it to be treated otherwise than as a distinct genus, has most affinity with the 
subcylindrical species of Carpophilus.

Oblong-ovate when the head is protruded, when bent down oblong in front and oblong- 
ovate behind, subcylindrical, somewhat shining, thickly and deeply punctate, black ; the

depressed behind the forehead, and with a deep, concave, subcordiform depression in 
front, the broad bieurved end in front; sides of the epistome sinuate, margins transverse 
* In the examination of this part it became broken, and the fragments showed that it had split longitudinally into 
horizontal plates. .
