the union of the radius and subcosta, and one on the last 
radial cross-vein beyond the stigma, all prominent; usually 
a few cross-veins obliquely beyond the rhegma less dis- 
tinctly marked; many of the cross-veins are dark only at 
ends, the few cross-veins in apical area are pale, behind 
cubitus and toward tip are more dark cross-veins. In hind 
wing the three apical dark marks are present, but none near 
end of anal. 
The pronotum is rather shorter than in E. nigribasis, the 
hair above is black, no long white ones on lower sides. 
The fore wings are shaped more like E. macer, more 
broadened beyond the anal vein than in E. nigribasis; five 
to seven cross-veins before the radial sector, six radials be- 
fore the stigma, about seven branches to radial sector, two 
or three cross-veins between cubital fork and first anal vein, 
and about five before cubital fork, none crossed. 
The legs are slender as in other species, the basal tarsal 
joint fully as long, the spurs on front legs are equal to three 
joints, those of hind pair a little more than two joints. 
Length of fore wing 22 to 25 mm., width 7 to 8 mm.
