This species differs from E. ruhricolUs, which we have from 

 Aneiteum and Mallicollo, in the purer hyaline of the trans- 

 parent wing-spots, the shorter basal spot, and less oblique 

 central patch on primaries, the much more restricted hyaline 

 basal area of secondaries, the more prominent ochreous shoul- 

 ders, the completely ochreous basal segment of abdomen, the 

 much greater width of metallic green on the abdominal seg- 

 ments, and the orange ventral surface of the abdomen. It is, 

 in fact, a far more beautiful insect.
