a'^ Snout, frontal, and |)arietals black, followed by a yellow ring and this by a broad 



red one Flaps eurtixanthus. 



There are, besides, several important characters derived from struct- 

 ural and proportional diiferences, notably in the size of the froutal 

 and the internasal shields. 



Asa rule E. fulvius differs from E. euryxanthus in having the second 

 row of temporals consisting of only one shield against two in latter; 

 but this character is by uo means constant.
