1. Eyes of the male very large, broadly contiguous beneath, narrowly 
separated by the vertex above; male hypopygium with the two pleural 
appendages generally similar to one another, slender, tapering to the 
acute and slightly curved tips; female ovipositor short, strongly 
curved, the tergal valves blackened and minutely serrate along the

Eyes of the male smaller, widely separated by the vertex; male hypo- 
pygium with the two pleural appendages dissimilar in appearance, the 
dorsal one more or less flattened, the ventral appendage slender with 
a perpendicular spine at or near the tip; female ovipositor, of the 
species as known, long, but slightly curved, the tergal valves pale and

2. The ventral pleural appendage of the male hypopygium with a very long 
spine some distance before the tip to form a fork with nearly equal 
arms or the spine slightly exceeding the actual tip...E. furcifier n. sp. 
The ventral pleural appendage of the male hypopygium with the spine 
smaller, located at the extreme tip or small and situated slightly back 
from the apex, the forked appearance not so evident................ 2 
3. Spine of the ventral pleural appendage of the male hypopygium small, 
shorter than the width of the blade at this point, located some distance 
before the tip of the appendage and shorter than the enlarged tip 
beyond it; gonapophyses of either side produced into a blackened di-

Spine of the ventral pleural appendage of the male hypopygium longer,

Rostrum and palpi green. Antenne green, the terminal flagellar seg- 
ments a little darker. Eyes of the male very large, broadly contiguous on 
the ventral side of the head, separated by the narrow vertex above. 
The thorax and abdomen, including the halteres, wings and their veins 
light green as in E. chlorophylla. Legs yellowish, the segments tipped with 
green. Male hypopygium with the pleurites more slender than in chloro- 
phylla, the two pleural appendages generally similar to one another in 
size and form but the dorsal one a little shorter than the ventral or inner 
one. The appendages taper gradually to the acute blackened tips which 
are curved, the outer or dorsal appendage a little less curved than the 
other and with an indistinct appressed tooth before the tip. Gonapophyses 
with a powerful curved blackened hook on either side of the penis-guard. 
The female is similar to the male but somewhat larger, the ovipositor 
small, with the tergal valves comparatively short, strongly upcurved and
