indistinct transverse shade and marginal streaks; a black discal spot. Hindwings dark grey, towards the 
base lighter. Expanse of wings: 21 mm. Cuba. 
E. testaceum Druce. The body is grey, the antennae black. Forewings diaphanous white, behind the 
cell, at the apex, distal and proximal margin clouded grey. Hindwings diaphanous white. In the $ the meta- 
thorax is whitish-haired. Expanse of wings: 40 to 46mm. Venezuela. 
E. zephyrum Schaus. Anterior body grey-white, hindhead and neck like the abdomen above yellow, 
the latter above with subdorsal grey stripes, the two last segments all grey, beneath grey. The white fore¬ 
wings have grey veins and stripes on the cellular and submedian folds; anterior transverse line dentate; the 
posterior one, encircling the large discal spot, runs from the upper median vein to the middle of the proximal 
margin; behind it a large, white area with likewise white veins, in the apex and at the anal angle a greyish- 
spotted obscuration. The hindwings semi-transparent, iridescent, with a narrow, dark border. From Costa 
Rica. -— songoense subsp. nov. (25 h) has above a quite unicolorous grey abdomen, being all white beneath; 
the cellular and submedian folds are not striped grey, but the veins are grey-brown also in the marginal area, 
at any rate all the markings brownish. Bolivia (Rio Songo), from Bang-Haas. 
E. aetolia Druce has a dark grey anterior body; the neck is bordered with white; abdomen above 
black, beneath dark grey, the anal tuft is light yellow. The forewings are grey-brown, at the base the costal 
and distal margins are striped white, the proximal margin in its whole extent bordered with white. Hind¬ 
wings diaphanous blackish, in the disc lighter, with white fringes. Expanse of wings: 26 mm. Colombia. 
E. phaeoproctum Hmps. (= . costulatum Druce nec H.-Schdff.) resembles aroa ; it is somewhat smaller 
and has a pronounced dark middle spot at the cell-end, the light, arch-shaped band before the apex is 
considerably narrower and the abdomen in both sexes unicolorously brown-grey. Distributed from Mexico to 
Panama. 
E. venosa Schaus. Body blackish-brown; forehead whitish; in the neck 2 orange spots; an orange 
stripe below the collar and on the shoulder-covers. The first abdominal rings are white underneath. Fore¬ 
wings whitish, with broadly grey-striped veins, cellular and submedian folds, except on a large, round, white 
spot behind the cell; the basal half of the costal margin and the proximal margin are orange; at the cell- 
end and behind the white spot there is more densely grey dusting. Hindwings light blackish-brown, towards 
the margin darker. Expanse of wings: 23mm. Costa Rica. 
E. intranotatum Dogn. Body blackish-brownish; 2 spots on the neck, and the borders of the shoulder- 
covers are of a bright yellow, the anal apex blackish-brown; the first abdominal rings beneath whitish. Fore¬ 
wings yellowish-white, the veins and the distal two thirds of the costa broadly blackish-brownish; behind the 
cell is an oval white spot, extending from the subcosta to the lowest radial. Hindwings pale blackish-brown, 
in the disc diaphanous. Expanse of wings: 26 mm. Ecuador (Loja). 
E. pometinum Druce (26 i) is coloured light grey-brown on the body and forewings, on the latter 
mixed with reddish-brown; above the proximal margin there is a brown stripe, before the middle a curved, 
dark line, at the transverse vein a spot extending as far as the costa, and behind the middle a faded, broad, 
blackish-brown oblique band from the apex to the proximal margin, with an indistinct, light, undulate, ante- 
marginal line and a blackish spot behind it at the proximal angle. Forewings light grey-brownish, towards the 
margin darker. Expanse of wings: 26 mm. Panama. 
E. birchelli Druce. Anterior body light brown, abdomen darker, more blackish-brown. Legs light 
brown, curled white. The forewings are light brown, strewn with a darker brown, with a black spot at the 
cell-end. Hindwings diaphanous blackish-brown. Expanse of wings: 34mm. Colombia (Bogota). 
E. plumbicollum Hmps. (25 i) is easily recognizable by the silvery-blue colour on the forehead, vertex, 
collar and prothorax. The animal is otherwise dark chocolate-brown, on the forewings with whitish diffuse 
spots below the base of the cell, in the cell-end and towards the margin between the inner-marginal vein and 
lower radial. Hindwings blackish-brownish, towards the base more thinly scaled. Expanse of wings: 36 mm. 
Brazil (Sa. Catharina). 
E. lineatum Dogn. has a reddish-brown head and thorax, mixed with white. Abdomen blackish- 
brown, anteriorly and posteriorly with interspersed whitish scales, with whitish lateral spots and ventral bands. 
Forewings whitish, thinly scaled; near the base a short, reddish-brown band; 2 antemedian, irregularly den¬ 
tate lines; at the cell-end a spot in the shape of an 8; 2 postmedian dentate transverse lines, the distal 
one thickened to a spot at the costa and proximal margin, and a similar, antemarginal line thickened also 
in the middle; a marginal line and dots at the ends of the veins. Hindwings hyaline with a brownish border 
and veins. Expanse of wings: 46 mm. Ecuador; Bolivia. 
E. hoffmannsi Rothsch. is much smaller than the preceding. The forewings are not semi-diaphanous 
whitish, but light yellow-brownish, the markings much less distinct and of a dull wooden-brown colour, not 
chocolate-brown. The last abdominal ring is of a bright yellow, not dirty-brown. Length of forewings: 
20 mm. Peru; Ecuador.
