nearly straight, placed just behind the shoulders, and the other 

 two curved and angulated at the suture. The inner, outer, and 

 hind edges ai'e narrowly margined, and there are traces of three 

 slender lines crossing the transverse bars longitudinally. 

 I know only a single male.

Tliis is a very slender-bodied species with a pattern similar 

 to that of E. nitidicauda and paivce. In its undivided hind 

 claw and the metallic scales confined to the head and legs it 

 shows a closer relationship to the latter. The thoracic pattern 

 is almost the same, but the yellow bars upon the elytra, 

 both longitudinal and transverse, are very slender, and only two 

 of the latter, both situated before the middle, are recognizable. 

 The most distinctive feature of the species is found in the very 

 broad hind tibiaa, especially in the male. The abdomen in that 

 sex is very strongly arched and the pygidium longer than it is 

 broad.
