CERAMBYCID-E. 



antennas of the female shorter than the body, more pubescent than 

 those of the male, the first joint sparsely punctured, the third and 

 succeeding joints somewhat flattened above, but not roughened at 



the edges. Prothorax a little 

 longer than broad ; the disc 

 with a slightly raised oblong 

 space in the middle, the rest 

 of the surface rather strongly 

 transversely wrinkled but 

 with the ridges more or 

 less broken and convolute 

 towards the sides. Elytra 

 with a slight elevation close 

 to the suture at about 

 one-fourth of their length 

 from the base; each elytron 

 obliquely truncate at the 

 apex, with a spine at the 

 suture and a feeble tooth 

 at the outer angle ; the sur- 

 face, especially where rubbed 

 bare of pubescence, has two 

 kinds of punctures, some 

 minute and very dense, others 

 larger and less densely 

 spread. The claw-bearing 

 joint of the tarsi long and 

 the paronychium nearly 

 always distinctly visible 

 between the claws. 



As will be seen by the 

 measurements given, this 

 species varies in size to a remarkable extent. It varies also in the 

 relative length of the male antennae, these are shorter in propor- 

 tion in small specimens and longer iu the larger and more fully 

 developed ones. 



Length 20-60 ; breadth 5-16 mm.
