Mr. Westwood on the Affinities of Clinidium — 237 
The genus was established by Schénherr in the Kongl. Vetensk. nya Acad. 
Hand]. for 1809; and in the same paper, (which is written in Swedish and con- 
sequently unintelligible to me,) are contained his observations upon the 
structure of the tarsi of the Cucuji. 
Note C. 
Since the preceding observations upon a supposed connexion between the 
Lucanidgz and Prionide were penned, I have casually examined a most interest- 
ing insect, contained in the Rafflesian cabinet, which serves most satisfactorily 
to connect the two families. Its general appearance is that of a Prionus, with 
short trigonate advanced mandibles, and moderately long antenne; but the 
latter, on a closer examination, are decidedly those of one of the Lucanide, 
the basal joint is scarcely longer than the third, and a slight elbowing of the 
antenne is observed at the second joint, the last three joints are not longer than 
the precediny joints, and very slightly produced on the inside, giving these 
organs the appearance of being almost setaccous. The joints of the ¢arsi are 
cylindric, but the insect is heteromerous!

In addition to the affinities of the Cucujide mentioned above, I have en- 
deavoured to prove, in a paper upon the singular family Pausside, which I 
have presented to the Linnean Society, that the former family may perhaps be 
considered as having the greatest affinity with the Pausside, particularly when 
we notice the depressed bodies, the formation of the antenne, and especially 
the pentamerous, or rather subpentamerous, farsi of several of the genera in 
each family. It is by means of such genera as Rhysodes, Clinidium, Catogenus, 
&c., that I consider the connexion may be traced, although many links remain 
to be discovered. 
Note E. 
There is a valuable paper, by Gyllenhal, upon the genus Parandra, Latr., 
inserted in the Kongl. Vetensk. nya Acad. Handl. for 1817, in which the 
author has noticed the structure of the tarsi in the insects included in it, and 
has described four species.
