considered it as a Ctiralus, to which genus it is certainly 
more nearly related both by habit and habitat than to Cl- 
an (Ida : still, however, it has considerable affinity with 
the latter genus, and may be regarded as one of the links 
which connect it with the former. In the Systema Eleu- 
tkeratorum, Fabricius has placed this insect in the genus 
Drypta, which he adopted from that most accurate ento- 
mologist M. Latreille, who in his late work (Hist. nat. 
generate et particuliere des Crustaces et Insectes, tom. iii. 
p. 87) has placed it in the third family (Caralici) of his 
first Section (Feelers six, all the Tarsi 5 -articulate) of his 
first Order (Coleoptera) . Under this it belongs to his 
Division A, (Cderipedes) , and subdivision iv (Longipalpati) . 
The most striking circumstances in which this insect 
differs from Caralms are its feelers, which instead of being 
filiform, with the intermediate ones not remarkably more 
slender than the others, are elongate and subcapitate; the 
last joint being much larger than the rest, and securiform or 
hatchet-shaped ; and the intermediate ones, which are fili- 
form, and longer than in Carahis, are much slenderer 
than the others. The antennae are strikingly distinguished 
from those of every other Caralus, by the remarkable 
length of the first joint. The thorax, though it is rather 
obcordate, has no margin, and is subcylindrical. The maxillae 
also are protended, and the eyes very prominent. We shall 
now give a very particular description of this singular in- 
sect, that our readers may be better able to judge of its claim 
to be considered as belonging to a distinct genus. 
Body depressed, blue-green, rather hair)', hairs diverging. 
Head elongate, very narrow, covered with impressed 
points. Mouth rufous. Jaws protended, toothless, acu- 
minate, forcipate at the end. Apex of the valvulse hooked, 
on the inner side setoso-pectinate. Feelers elongate, ru- 
fous. The exterior, or valvular, consisting of three joints; 
the first elongate, subclavate; the intermediate subclavate ; 
the last large, compressed, nearly. triangular : the two last
