342 MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 
Scutellum rather large. Elytra not striated, leaving the last two or three abdominal 
segments exposed, each elytron usually more or less obliquely truncate from the suture 
backwards ; exterior apical angles rounded. Abdomen with the second and third segments 
. usually very short; first, fourth, and fifth tolerably large ; an additional rounded ventral 
anal segment in the males. Prosternum widened and rounded behind, reaching to the 
mesosternum. Metathorax without axillary pieces.  Fimbris absent or minute. Legs 
short, robust; thighs canaliculated below to receive the base of the tibize, which are 
widened at the apex, their terminal spurs rather strong; the first three articles of the 
tarsi dilated, hairy beneath ; claws simple. 
These characters must not be expected to be found rigidly applicable to every species 
which belongs to this genus. It contains such a large number of species, many of which 
1 have not had the opportunity of dissecting, that it is not improbable that some may 
turn out to deviate in one or other of the more minute characters. The more important 
characters will, however, be found in them all. 
(Subgenus UnoPHORUS (ovpa, tail; $opoc, bearer).) 
Abdomen segmentis tribus ultimis supra expositis; elytris haud elongatis. 
This subgenus differs from the normal Carpophili in having the last three dorsal seg- 
ments of the abdomen exposed, instead of only two, while the elytra are only of moderate 
length. There is another subgenus (Heterodontus) in which three segments are exposed, 
but in it the elytra are much elongated and as it were overshadow the exposed segments. 
In this it is not so. With one exception, all the species yet known are shining, nearly 
glabrous, and hard in texture, while the other Carpophili are more or less pubescent and 
either shagreened or soft.

Habitat in Europa meridionali. 
A very distinct species. Oblong, subparallel, moderately convex, nearly glabrous, with 
scarcely any perceptible pubescence, black, somewhat shining; antenn:e red; mouth 
more or less ferruginous. Head thickly and deeply punctate, the forehead on each side 
with a slight impression. Thorax of the breadth of the elytra, a half broader than long, 
rounded on the sides, widest in front, towards the sides more densely and very coarsely 
punctate, the punctures variolose; more sparsely and finely punctate in the middle; the 
marginal edging with a deep furrow, disappearing behind the anterior angles, which are 
somewhat projecting and rounded, the posterior angles very obtusely rounded; an im- 
pression on each side, some distance within these angles, in which the punctures are 
deeper. Scutellum finely punctate at the base. Elytra a half longer than the thorax,
