COLEOPTERA. 
427 
Cerophytum, Lat,, 
Is removed from the others by the tarsi, of which the four first 
joints are short and triangular, and the penultimate is bifid. 
The antennae of the males are ramous on the inner side, the base 
of the third joint and of the following ones being extended into a 
widened branch rounded at the extremity ; those of the females are 
serrated *. 
In all the other subgenera the joints of the tarsi are almost cylin- 
drical and entire. 
Sometimes the head is plunged into the thorax up to the eyes ; the 
anterior extremity of the praesternum projects under the head, and 
its margin is arcuated. 
In some, the labrum and mandibles are concealed by the anterior 
extremity of the praesternum, the clypeus or epistoma being widened 
and laid over it. Such is the 
Cryptostoma, Dej . — Elater, Fab. 
In which the internal angle of the summit of the third joint of the 
antennae, and of the seven following ones, is prolonged into a tooth ; 
the second and fourth joints are shorter, the last is long and narrow, 
and there is a straight linear branch on the inner side of the third, 
near its origin. 
The mandibles are unidentated under the point. The maxillae 
present but a single lobe, and are small and membranous, as is also 
the ligula. The palpi are very short. The tarsi are small, thin, 
and almost setaceous. 
The only species known, the Elater denticornis. Fab., is found 
in Cayenne, whence it was sent to the Mus. d’Hist. Nat. of 
Paris by M. Banon. 
Ne3iatodes, Lat. 
First joint of the antennae elongated, and the five following ones 
forming reversed cones, equal, the first or second of this number 
excepted, which is somewhat shorter, and the five last thicker and 
almost perfoliate ; terminal joint ovoid. 
The body is almost linear f. 
Now the mandibles and labrum are exposed. 
Here the antennae of the males have a flabelliform termination. 
They form the 
Hemirhipus, Lat. 
Of which all the species ai'e foreign to Europe J. 
There, these organs, in the same sex, are longitudinally pectinated. 
Stenicera, Lat. § 
In the following subgenus or 
* Lat., Gener. Crust, et Insect., IV, 375. The Malasis spliondyloides, Germ., Faun. 
Insect. Eur., XI, 5, is closely allied to the female of the species uhicli is the type of 
the subgenus. The Melasis picea, Palisot de Beauvois, Insect. d’Afr., et d’Amer., 
VII, 1, has also some analogy to the Cerophjta.
