260 CERAMBTCIDJE. 



margin ; the apex is broadly but not very densely covered with 

 white pubescence so as to form a third band ; the derm beneath 

 is, however, not pale as in the case of the other two bands. Head 

 and prothorax very closely and rather finely punctured ; disc of 

 prothorax sparsely granulate. Body beneath dark brown, with 

 spots of white pubescence on the mesosternum and metathoracic 

 episterna, and four narrow transverse bands on the abdomen. 



Length 12| ; breadth 2 mm.

Type, C. speciosus, Schneid., a European species. 



Range. Palaearctic and Oriental Eegions, a few species occur in 

 Australia and Africa. 



Head with a slight, subacute elevation on each side between the 

 antenna. Antenna rather closely approximated at the base, the 

 distance between them distinctly less than that between the lower 

 lobes of the eyes ; variable in length, but nearly always shorter 

 than the body, very rarely extending to the apex of the elytra in 

 the <3 , not spined at the apex of the joints. Prothorax oblong- 

 oval or subglobular, longer than broad. Elytra moderately long, 

 truncate at the apex, with the outer angles dentate. Femora 

 more or less gradually thickened ; the hind femora usually extend 

 past the apex of the elytra in both sexes ; middle femora in many 

 of the species, the hind pair also in some, furnished with a fine 

 carina along each side. First joint of the hind tarsi much longer 

 as a rule than the next two joints united. 



This genus includes a very large number of species, which are 

 generally a little narrower and less robust than those of Clytus and 

 Xylotrechus, with the antenna? somewhat longer, less thick, and 

 much more closely approximated to one another at the base. In 

 the type, C. speciosus, the antenna are longer than usual, and in 

 other respects also this species is by no means typical of the great 

 majority of the forms included in the genus. The name Clytan- 

 thus, Thorns., by which the genus is generally known, has a 

 doubtful priority over Caloclytus, but should, in my opinion, be 

 restricted to certain Central- American forms that agree in struc- 

 ture with C. tricolor, Chevr., the species indicated by Thomson as 

 the type of his genus.
