COLEOPTERA. 431 
Here the praesternum is not prolonged into a point, and there is 
no anterior cavity in the mesosternum. 
Sometimes all the joints of the tarsi are entire, and without a pro- 
jecting membranous palette underneath. 
Anelastes, Kirby. 
The antennae remote at base, short, almost granose, with the last 
joint* nearly crescent-shaped; last joint of the palpi almost in the 
form of a reversed cone. 
A. Dnirii, Kirb,, Lin. Trans., XII, xxi, 2. The only species 
quoted. 
Callirhipis, Lat. 
The antennae closely approximated at the base, inserted on an emi- 
nence, and from the tliird joint, in the males, forming a large fan ; 
the last of the palpi ovoid, the same of the tarsi almost as long as 
all the others taken together, and presenting between its crotchets a 
little silky and linear appendage. 
The species which is the type of the subgenus — C. Dejeanii — 
is found in Java, and was sent to the Museum of Paris by M. 
Diard and the late M. Dirvaucel. The antennae consist of but 
eleven joints, and in that differ from those of the Rhipicerae, 
which have the same form, but are composed of more joints in 
individuals of the same sex or the males. 
Sometimes the inferior surface of the tarsi is furnished with mem- 
braneoirs palettes, or their penultimate joint is profoundly bilobate. 
In the two following subgenera, the inferior surface of each of the 
four first joints of the tarsi presents two membranous and projecting 
lobes ; the last is long, and terminated between the crotchets by a 
little silky appendage. The antennae of some are composed of more 
than eleven joints, and are flabelliform ; those of the others consist of 
eleven, and are serrated, the four last larger, and forming a club. 
Sandalus, Knock. 
The antennae, at least those of the females, only a little longer 
than the head and consisting of eleven joints, the third, and with 
the exception of the last, the following ones serriform, the four last 
somewhat more dilated, forming a club ; the terminal joint almost 
ovoid or rounded, or very obtuse at the end f. 
Rhipicera, Lat. Kirby . — Ptyocerus, Hoff . — Polytomus, Dalm. 
The antennae flabelliform in both sexes, and composed of numer- 
ous joints (from twenty to forty), but fewer in the females. 
* The third is longer than the preceding and following one, whilst in Cebrio, this 
joint and the second are shorter than the fourth and following ones. These organs, 
like those of the Elaterides, seem to be composed of twelve joints, the eleventh being 
suddenly contracted near the extremity, and terminated by a point having the 
appearance of a little conical or triangular joint.
