222 Mr. Westwood on the Affinities of Clinidium 
parvo paullulum producto, (C.) et posticé collo brevi instructum—genis 
subtus utrinque rotundato-productis,* maxillarum basin tegentibus. B. 
Oculi parvi, laterales, reticulati, A. 
Thorax oblongo-quadratus, planus, capitis latitudinem equans sed lon- 
gitudinem ejus superans, basi vix angustiori, angulis acutis. 
Elytra oblongo-quadrata, linearia, plana, lateribus deflexis, thoracis 
latitudine, 
Pedes breves, longitudine fere equales, femoribus crassis, tibiis ad 
apicem crassis, et trispinosis, éarsis fere tibiarum longitudine, articulis 
5 simplicibus, 1mo. paullo minori, unguibus minutis. 
Of the characters detailed above, the most interesting, with reference 
to the affinities of the genus and its separation from Cucujus, are the 
flatness and very oblong shape of the body, the formation of the antennz 
and trophi, the anterior production of the lateral parts of the under side 
of the head, and the five-jointed tarsi. 
If the general formation of the antenne, palpi, and legs are compared, 
we are immediately struck with the resemblance between this genus and 
the two preceding. 
Of this genus, which appears to be the American type of form, in 
addition to the Cuc. rufus, Fab., the cabinet of the British Museum con- 
tains two, and that of the Rev. F. W. Hope, three other distinct species, 
Most intimately allied to the last genus is an insect received by Mr. 
Hope from Dr. Klug under the name of Isocerus carinatus, Klug, (MSS.?) 
an inhabitant of the Cape of Good Hope. This generic name (it having 
been employed by Tlliger to designate the genus Parandra, and conse- 
quently sinking into a synonym of that name, and also being still em- 
ployed by Megerle and Dejean for a genus of Blapside) Mr, Hope pro- 
poses to change to 
ANISOCERUS. 
In addition to the geographical distinction between this genus and the 
last, a slight examination enables me merely to state that it also appears 
to differ in being considerably longer in proportion, and not quite so flat 
in the thorax and elytra. 
* This formation is perceivable, but*in a much less developed state, in Scau- 
eus and Eurychora, Vide Kirby and Spence, Int, to Ent. Vol. III. p. 489.
