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.

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

 antenna3. Antennae rather closely approximated at the base, the 

 distance between them distinctly less than that between the lower 

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

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

 the S , 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. Eemora 

 more or less gradually thickened ; the hind femora usually extend 

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

 of the species, the hind pair also in some, furnislied with a tine 

 carina along each side. Eirst 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 Chjtus and 

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

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

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

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

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

 rhus, Thoms., by which the genus is generally known, has a 

 doubtful priority over Caloclytus, but should, in my ojiinion, 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.
