Genus CCLXI. — Bostrichus, Geoffroy. 



Antennas inserted close to the anterior margin of the eyes ; basal joint robust ; 

 second short, subclavate ; third subcylindric ; four following subtransverse ; 



Genus CCLX. — Sinoxylon, Duftschmid. 



Antenna? short, slender at the base, the club composed of three transverse sub- 

 laminated articulations. Palpi filiform, with the terminal joint elongate : 

 thorax gibbous, cucullated : body short, villose, stout : elytra retuse, spinose : 

 legs short : tibia simple : tarsi slender, simple. 



The transverse sublaminated capitulum of the antennae, retuse spinous elytra, 

 and villose body, appear to be the chief external distinctions of this genus.

This insect having been incidentally (but improperly) noticed as a British species 

 from confusion in the synonymy, is here inserted for the sole purpose of stating 

 that it has no pretensions to such a claim, as from the mere circumstance of 

 its omission a negative rather than a positive inference as to its native origin 

 could be drawn.
