dull ashy-brown hue, and much narrower and smaller. The 

 forehead is uneven, punctured, and of a dull slaty hue; the 

 third antennal joint in the male is much less swollen than in 

 E. ruhefadus, and therefore more elongate, and fusiform rather 

 than ovate in shape. The thorax is uneven and obtusely tuber- 

 culated on the sides, but is destitute of longitudinal lines, except 

 two very short ones near the base. The elytra are of the same 

 grey leaden hue over their basal halves, and have a pale belt 

 beyond the middle ; but the latter does not expand on the mar- 

 gin. The dark apical streaked spot has an ashy transverse 

 streak across the middle. 

 Also found at Ega.
