and shape of the elytral spots are simihir, but in most 

 examples of E. haroni the black lines which proceed 

 from the ends of the ivory spots are expanded into a 

 broad discoidal vitta. The posterior femora and the 

 apex of the elytra are bispinose, the exterior spine of 

 the femora and the sutural spine very short. The thorax 

 is feebly rugose-punctate, and has two rather prominent 

 antero-discoidal black tubercles, and a similar one on 

 each side near the anterior angle.

 Temax examples show much variability in the various 

 differential features.
