222 Mr. Westwood on the Affinities of Clinidium.

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 antennae 

 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 antennee, 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 Cue. 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 lUiger 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 BlapsidaJ 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- 

 tus and Eurychora, Vide Kirby and Spence, Int. to Ent. Vol. III. p. 489.
