 each elytron with two oblong-oval spots at base, a large roundish 

 spot laterad in the middle, and two very large oblong-oval spots 

 in apical third, one of the latter being located at the outer 

 margin. Underside of mesothorax, metathorax, and first ab- 

 dominal sternite with a spot laterally. Femora with a spot on
