row of four to six short, dorsocentral setse; three humeral 
bristles (two anterior, one posterior) ; two rows of noto- 
pleural setae (before base of wing), those of the posterior 
row very long; two presutural bristles (one short and one 
long) close to the notopleurals ; on each side two to five 
prescutellar bristles, the external ones placed close to the 
base of the wing, the single internal one very long, far 
from the others and seemingly in line with the dorsocen- 
trals ; scutellum with one or two pairs of apical setae. Abdo- 
men with sclerotized tergal plates as follows : a short basal 
plate, more or less fused with the first pleurite on each 
side (though generally much darker) and excised in the 
middle by a broad triangle, the apex of which extends as a 
narrow notch; hind margin of basal plate with a row of 
three to eight long setae on each half, the disk either bare or 
with a few setae mostly in a transverse post-median row; 
second to fourth tergites each with a more strongly sclero- 
tized transverse plate near the hind margin, variable in 
size, the plate bearing a pair of distant setae or a medially 
interrupted row of three to six setae ; most of fifth and sixth 
tergites strongly sclerotized, short, bearing one or two pairs 
of long setae near the apex; the tergal area occupies about 
the median half of the dorsal surface, the remainder being 
covered by four partly sclerotized pleurites, which are even 
more developed ventrally than dorsally and bear scattered 
setae (more numerous ventrally). Ventrally the abdomen 
has a strongly sclerotized basal crescent-shaped sternite, the 
disk partly covered with short, thick, almost spine-like setae 
(two of these much longer in each apical corner) ; remainder 
of median ventral area not sclerotized, but soft and fairly 
uniformly covered with scattered short setae. Setae of ster- 
num short, spine-like, few in number and placed more or 
less in transverse rows. Claws of all tarsi robust and slightly 
asymmetrical ; apical spur of fore and mid tibia stout ; fore 
coxa dorsally without retrograde spur, but with a long seta. 
As in Lipoptena, the wings break off apicad of the base, 
shortly after the adult hatches. I have seen the complete wing 
of E. sepiaceus (Fig. 2) and E. paradoxus. It is shaped as 
in Lipoptena cervi and has the same type of venation : only 
three well-developed longitudinal veins, apparently the first 
(R^, third (R 4+5 ) and fifth (M g +C i ) ; the sixth (2d An)
