 spécimens from Ikuta], sometimes emitting from its postero-exterior angle 

 to the ocelli an oblique band usually reduced to a small spot close to the 

 ocelli, l_in the type spécimens a more or less abbreviated médian line to 

 vertex], two transverse apical spots to pronotum, two smaller spots behind 

 thèse, a large latéral spot on each side of pronotum not reaching apical angles 

 but emitting a narrow continuation to the humerai angles, a triangular
