 This fine genus seems to have been misunderstood by authors, 

 and another set referred to it, apparently in ignorance of Serviile's 

 type, while the more recently described species have been brought 

 together by M. J. Thomson under the name of Rhamses. 'J'he 

 principal characters distinguishing this genus from Monochamus 

 are the long anterior legs of the males, the tibiae of which are 

 denticulated along the lower edge and armed near the apex with 

 a strong tooth. With regard to the armature of the prothorax.
