This species resembles E. Grimaldii, Dollfus *, more closely 



than it does any other species of the genus. It differs in the 



following characters : — 



1. The greater number of joints in the flagellum of tlie 

 first pair of antenna}. In our species there are live joints, 

 while in E. Grimaldii the flagellum is uniarticulate. 



2. In the fewer number of joints in the flagellum of the 

 second pair of antennae. In our species there are only 

 twenty-five, while in E. Orimaldii the flagellum contains 

 thirty-two articles. 



'6. In the presence of four spines on the posterior margin 

 of the terminal segment. In E. Grimaldii the posterior 

 margin is denticulate ; in our species it is denticulate and 

 also bears four spines.
