 forming a ray behind each callus and thus leaving the median line pale 7 

 Second antennal segment without prominent exserted hairs, or if pres- 

 ent, not equal to more than twice the thickness of the segment ; pro- 

 notal disk without distinct rays, or if black then the lateral margins 

 not distinctly paler .......... 8
