brown through the dense pale pubescence. Thorax in front and 

 at sides with longer golden-yellow hairs ; in front of and around 

 wing-base with black bristles. Abdomen at the base with thick 

 and long golden-yellow hair; 2nd segment on fore border with a 

 whitish- yellow cross-band. Head reddish brown, epistome paler, 

 frons darker; pubescence short, bright golden yellow; frons 

 black on hinder part. Antennas brown, 3rd joint very elongate, 

 gradually tapering and produced into the style. Legs reddish 

 yellow, knees rather darker ; tarsi brown ; femora with shining 

 scales ; all bristles black ; pulvilli rudimentary. Wings sooty 

 brown, darker on front margin and more reddish, with eight 

 black spots : two at base of outer marginal (cubital) cell,. 

 two at base of 2nd posterior cell, one each at bases of 3rd and 

 4th posterior cells, one on outer side of discal cell, and the last 

 one suffusing the anterior cross-vein. Cross-vein joining upper 

 branch of cubital vein to subcostal vein, with a recurrent 

 appendix ; only three submarginal cells. Length 4 lines. Two 

 specimens ; Ceylon." 



The above is Schiner's description ; he compares it with 

 E. alexon, Walk., and punctulata, Macq. 



Type presumably in the Vienna Museum.

2 . Head : froiis at widest (level of antennae) one-third the 

 width of the head, narrowing at vertex to half this width ; dark 

 brown, covered with close, light brownish-orange scales, which 

 become lighter coloured below the antenna ; the whole frons 

 covered with short black hairs ; ocelli small, black, close together, 

 placed on a small tubercle ; mouth-border yellow, proboscis dark 

 brown. Antennae black; 1st and Und joints thickly beset 

 above and at the sides with strong black bristles ; 3rd joint 

 rather long, absolutely bare, with a very distinct style, which 

 itself bears a microscopic but distinct apical joint. From the base 

 of the antennae obliquely to the edge of the eye there is on each 

 side of the frons a narrow groove, quite destitute of scales or 

 pubescence. Back of head broad behind the eye, with minute 

 black pubescence, and covered towards the sides with soft 

 yellowish-white scales, which may perhaps extend over nearly all 

 the back of the head in some specimens; a fringe of short, bright 

 orange-yellow hairs encircles the back part of the head, meeting 

 the dense pubescence of the thorax. Thorax dull black, with 

 some short black hairs towards anterior border, and in front of 

 the scutelluni ; front part of thorax (not extending to the dorsum 

 proper) covered densely with narrow, elongate, bright yellow 

 scales, which also extend to the sides of the thorax, and form fan- 

 shaped bunches below each shoulder and behind each wing;. 

 these scales become almost thick pubescence at the sides of the 

 dorsum, being especially thick above each wing. The true dorsum-
