This magnificent and striking form does not appear to be closely 

 allied to an}^ of the previously described species of the genus. In 

 general superficial appearance it resembles .E. hadia very closely, but 

 it is readily difi'erentiated by the form of the supra-anal plate and the 

 proportions of the posterior tarsal joints. 



Size large; form elongate ovate. Head projecting somewhat beyond 

 the pronotum, anterior margin very slightly arcuate; interspace 

 between the eyes almost twice as wide as that between the ocelli; ocelli 

 of medium size, not touching the eye; eyes elongate, strongly com- 

 pressed in the median and posterior portions; antenna? almost equaling 

 the body in length. Pronotum subheptagonal in outline; anterior 

 and antero-lateral margins arcuate; posterior margins obtuse angulate, 

 postero-lateral margins very short; all the angles very broadly rounded 

 except the posterior and the lateral pair which are blunt; lateral jDor-
