This resembles E. sulphureiventris rather closely, but is smaller, 

 rather shorter, with the pronotum much more deeply channelled 

 along the middle and on each side, so that four distinct carinte 

 are formed, the two median ones nearly straight and the two outer 

 strongly oblique. These are always black, whilst the depressed 

 parts of the surface contain blue scales. The scutellum is small 

 and may be with or without blue scales. The elytra are shorter 

 and broader than those of E. sulphtLreiventris , with a similar and 

 equally undefined and variable pattern formed by scales of a 

 rather brighter blue colour, wdiich are densest around the scutellum 

 and along the inner and outer margins. The exposed part of the 

 propygiclium, the pygidium, and the lower surface of the body Jire 

 densely covered, as in the Chinese species, with dull sulphur- 

 yellow scales, but the entire median part of the metasternum and 

 abdomen bear instead scales of a beautiful glistening blue, with 

 which the legs are also adorned, but less densely. There is a 

 denuded patch on each side of the metasternum. In the male the 

 front tibia3 are more elongate and the teeth shorter and much 

 closer together than in the female.
