tribe, •which are even of as firm and solid a consistence as the Ster- 
noxi, whose legs are never fitted for leaping, and whose body is ge- 
nerally an oblong oval, with the antennae of the males either pectinat- 
ed, flabellated, or serrated, the palpi filiform or somewhat longer at 
the extremity, and the posterior angles of the thorax prolonged into 
an acute point, present mandibles projecting beyond the labrum, 
narrow, and highly arcuated or in the form of hooks. The labrum 
is usually very short, and emarginated or bilobate. 
There, as in the Elaterides, the prsesternum terminates posteriorly 
in a point, received into a cavity in the mesosternum. 
The antennae, Avhicli in the males of some species are long, are 
composed of eleven pectinated or serrated joints. The last joint of 
the palpi is almost cylindrical or forms a reversed cone. 
Physodactylus, Fisc/i. 
An orbicular membranous pellet (sole on planta) on the inferior 
surface of the thi’ee intermediate joints of the tarsi ; the posterior 
thighs enlarged; the antennae, at least in one of the sexes, very short, 
serrated, and insensibly diminished towards the extremity. 
This subgenus has been established by the celebrated author of 
the Entomographia Imperii Russici, on an Insect from North Ame- 
rica, the P. Henningii, Letter on the Physodactylus, Moscow, 1824, 
Ann. des Sc. Nat. Dec. 1824, XXVII, B. 
Cebrio, Oliv. Fab. 
In Cebrio proper, all the joints of the tarsi are entire and without 
pellets, and the posterior thighs are not larger than the others. 
The species peculiar to Europe appear in great numbers 
after heavy rains. The female ■* of the best known species — 
C. gigas. Fab.; C .longicornis., Oliv., Col. II, 30, bis, I, 1, a, 
b, c; Taupin, I, 1, a, b, c, — differs greatly from the male; the 
antennae are hardly longer than the head, and the first joint is 
much longer than the others; the fourth and following ones 
united from a little oblong and almost perfoliaceous mass. The 
wings ax’e partly abortive. The legs are shorter, but stouter in 
proportion, than those of the male. The larva probably lives 
in the earth. 
The C. hicolor. Fab. f, and some other American species, in 
which the body is elongated, less arcuated above or almost straight, 
and with shorter antennae, appear to Dr. Leach to constitute a new 
generic section J. 
* Cebrio brevicornis, Oliv., Col. II, 30, his, I, 2, a, bj c ; Tenebrio dubius, Rossi, 
Fatin. Etrusc. I, 1, 2. This female, on account other antennae, appeared to me to 
form a new genus, which I accordingly established under the name of Hammonia. A 
species is found at the Cape of Good Hope, each Joint of whose antennae throws out 
a long and linear branch from the base of its internal side, and whose palpi termi- 
nate in an ovoid joint, and not in the form of a reversed cone, as in the other species. 
This latter may be separated from them.

J The Ceb. fuscus and ruficollis, Fab., have the form of the species he calls the 
giyas. The second was brought from Sicily by M. Lefevre. The Cebrio femo- 
ratus, of Germar, does not belong to the genus Anelastes of Kirby, as I once sup- 
posed.
