Morphology. — Basal flagellomere (Fig. 23) more incrassate than 
in E. crassicornis, second about the same, third to tip slender. All 
flagellomeres beset with upright hairs. Compound eyes small (see 
Table II). Hypandrium (Fig. 20) with distal prongs somewhat 
longer than in E. crassicornis ; these and sides of hypandrium, to 
extreme base beset with minute denticles. Disc'al lobe and regions 
to its sides and base bearing setae. Phallosome (Fig. 21) symmetrical, 
with somewhat flattened base; the inset, spatulate distal process 
larger than in E. crassicornis and bearing minute denticles. Para- 
proct (Fig. 22) as in E. crassicornis. Epiproct and posterior clunial 
margin as in Fig. 22. The latter differing from that of E. crassicornis 
in having sides slightly indented. 
Color (in alcohol). — Compound eyes and inner rims of ocelli 
black. Head yellow deepening to burnt orange on vertex with a 
spot of medium orange-brown in front of ocellar interval; clypeal 
striations faintly indicated by orange-brown mottling. Maxillary 
palpi pale brown on basal two segments, becoming darker distally 
on second ; third segment dark brown, distal segment black. Antennal 
scape pale brown, rest of antenna black. Mesonotal lobes orange 
peripherally, deep orange-brown in a broad central band running 
length of mesonotum. Thoracic pleura violet. Forewing membrane 
(Fig. 18) uniformly fumose-brown except small region in base of 
areola postica extending distally along vein Cuia; pterostigma and 
narrow stigmasaum white mottled in base with fumose brown. Veins 
of forewing fumose brown except following: Ri colorless from 
posterior apex of pterostigma to wing margin ; Rs pale brown at 
and immediately before and in its junction with Cuia, colorless im- 
mediately beyond junction; Cuia colorless before and immediately 
beyond junction with M; Cuib colorless. Hindwing (Fig. 19) uni- 
formly pale fumose brown. Coxae, trochanters, and femora yellow; 
tibiae and tarsi black. Membranous portions of abdomen (note 
variation below) longitudinally striped with purple bands: a broad 
band along each side including spiracles, a narrower band along 
dorsal mid-line; an incomplete band ventrally from hypandrium, 
widest in 7th segment, narrowing to its anterior end in third seg- 
ment; abdomen creamy white between purple bands. Terminal 
abdominal segments largely dark brown, paler on poorly sclerotized 
portion. 
Female. — Measurements (Table II). 
Morphology. — Flagellomeres slender (Fig. 24). Subgenital 
plate (Fig. 12) with narrow region of stem of T-shaped pigmented 
area shorter than in E. infumatus; setae distad of cross-piece of T
