The antennal lamellae are .somewhat .stout but m<Mlerately hmg. The eentml tulM'nIe is 

 lat.rallv'.impres-sed ami comparatively low. It is .somewhat variable, nnd may be .s<'anely 

 more olev3te«l than in r^ion^x-iTM/i /;irMX/»(« ; u.sually. however, it i.s soniewhat higher and 

 the apex may even Ik? faintly overhanging. The tine punctuiing on the hea»l is usually in- 

 eonspicuous nr ab-scnt. All the elytra! griMfves, except i>erhaps the lir«-t pair, are \<rv 

 finely puneturoil : none of theni are very deep.
