 cially the form of the second joint, the form of the thorax, and of 

 the legs, as well as the texture of the elytra being totally distinct, 

 exclusively of minor differences in the tropin.

Genus CCCLXXVII.— Clytus, Fahkius. 



Palpi short, subequal, with the terminal joint stout, obtrigonal. Antenme filiform, 

 shorter than the body, in the type subclavate, basal joint robust, curved, 

 second subglobose, third long and slender, the remainder decreasing in length 

 to the apex, the terminal joint subconic: head short, nutant: e^/ej lunate: 

 thorax globose, or elongate-acute^ suborbiculate, unarmed: elytra elongate, 

 gaping, scarcely covering the apex of the abdomen in the females : legs mode- 

 rate, anterior shortest, posterior longest : femora clavate, more slender in the 

 females : body somewhat cylindric. 



From all the preceding genera of this family Clytus differs by the 

 form of the palpi, especially of the terminal joints ; and from Cal- 

 lidium by the cylindric body and very globose thorax, as well as by 

 less evident dijGFerences : — the species are generally prettily marked 

 with arcuated transverse bands, while in Callidium they are ge- 

 nerally destitute of such markings.
