Bess. a. diff.— This species has a depressed form; it resembles 

 E. Santa-Anna, although it is not so much depressed, and more 

 slender. It comes very close to E. Isevis, but with a shorter 

 thorax. Not having the type, I dare not give a more approxi- 

 mate composition. It is a little larger than E. olmecus, and a 

 little smaller than E. Santa-Anna.
