Similar to E. variegata De Borre and E. obducia Mots., but 

 easily distinguished by tbe brilliant silvery-green scales covering 

 the pygidium and part of the lower surface. Tbe scutellum also 

 is larger. The scales forming the pattern upon the upper surface 

 are generally ochre-coloured, but sometimes pale yellow or of both 

 tints intermixed. Tbe head bears rather scattered golden scales; 

 the pronotum has a narrow median line, a marginal line, which 

 generally includes the front margin but does not extend past the 

 hind angles, and an oblique mark on each side, sometimes extend- 

 ing from the base to the front margin, sometimes abbreviated 

 in front and sometimes reduced to basal and median spots. The 

 scutellum is larger than in the two species just mentioned, and 

 has usually only a few scattered yellow scales. The elytra, in 

 addition to a. marginal line not including the base, have each two 

 narrow longitudinal straight lines on the disc extending from 

 the base nearly to the extremity. There may be also fragments 

 of three straight equidistant transverse bars connecting the 

 longitudinal ones. The scales of the propygidium, pygidium, 

 and legs are entirely pale silvery green in both sexes, and those 

 of tbe whole median part of the metasternum and abdomen in 

 the female. In the male the latter region is covered with dull 

 yellow and brilliant scales intermixed.
