E. olivaeetis, Lee. 



This species is of rather less slender form than laetu'gatus, but the 

 sculpture of the upper surface resembles it very closely. The under 

 surface of the pronotum is very densely punctulate, more so than the 

 majority of the specimens of rlparlus. The type and only one known 

 is a female, but its entire aspect appears to favor its reference to the 

 group with Ixviyatus rather than with the last three species.
