(E. sulphurea differs from (E. xanthoptera in its smaller 

 size (the males of (E. xanthoptera equalling in size the fe- 

 males of (E. sulphurea), in the squareness and greater size 

 of the foveolae of vertex, in the direction of the edges of the 

 ridge down the front (which in CE. sulphurea are brought 

 together at the vertex), in the direction of the hind-border 

 of the pronotum (which is much more angulated in (E. 

 xanthoptera), in the greater depth of the wing in (E. xan- 

 tho])tera, and also in the band of the wing, which in both 

 species has the inner border turned considerably inwards 

 close to the costal border, and then outwards again just 

 before the edge, but which in (E. sulphurea extends in- 

 wards fully half way to the base of the wing, while in (E. 

 xanthoptera it does not reach one quarter the distance.
