Sc. viridigrisea Strcl. Thorax greyish-green, abdomen greyish-hrown, Forewing light grey with greenish vlruU- 
scales. A black spot near the base at the costal margin and in the middle, another spot a little below the 'J 
costal margin. Interior line formed of 4 black spots, with a light edge, arcuate. Exterior line of 8 black 
spots, edged light, strongly excurved behind the cell. The enclosed median area is lighter, as it is less dusted 
green. A distinct black spot at the cross-vein, a round deep black spot in the submedian fold, very cons]ji- 
cuous. An excurved postmedian stripe intensely strewn with green and narrowed in the middle, behind it a 
double row of black dots. Hindwing greyish-brown. $ 23 mm. Cameroons. 
Sc. grisea Strd. Similar, somewhat larger, without the green dusting on the thorax and forewing, only grisea. 
in the basal area more intensely dusted black. The spots of the interior line mostly confluent, otherwise similar 
to viridigrisea. The similarly coloured median area shows the black spot in the submedian fold less distinctly 
defined than in viridigrisea and distinctly separated from the interior line. The apical part of the median area 
is dusted black. Hindwing somewhat lighter. 25 mm. Cameroons, Togo. — pallidegrisea Strd. shows the fore- palUde- 
wing less dusted black, therefore lighter. The median area is defined by rows of distinct black dots. The inner- 
most dots of the two rows are connected by a white radial line which is edged dark in front, but there is no 
black spot. Hindwing light grey, darker at the margin. (J 24 mm. East Africa. 
18. Genus: Hriopus Tr. 
Proboscis and palpi normal. Antennae of d ciliated, often thickened and angled in the middle. Thorax 
with a tuft in front and behind, a parted tuft in the middle. Abdomen Avith a long tuft on the first 3 segments. 
Distal margin of forewing slightly undulate, angled at vein 4. Vein 5 of hindwing below the middle of the cross¬ 
vein, the other neuration as usual. Type: juventina Cr. ((ptirjnireofasciaia) from Europe. 
1. Antennae of dentate and ciliated, with a hair-pencil on Y} of their length, then compressed, with 
3 thorns. Tibiae and the 1st tarsal joint long-haired. 
E. cornus-copiae Hotl. (8 g). Body and wings dark red-brown. Reniform macula as a white streak cornus- 
from the ends of which curved lines proceed, uniting in a triangle. Before it an indistinct dark interior line copiae. 
with a white spot at the costal margin. Exterior line light, notched. Traces of a dark undulate submarginal 
line. (^26 mm. Ogowe. 
2. Antennae of with a moderately thickened basal part, bent somewhat downward in the middle. 
E. maillardi Guen. (= rectilinea Saalm., recurvata Mr.) (8 h). Thorax and forewing dark red-brown, maillardi. 
the veins partly light, white basal streaks. Interior line double, white, rectangularly broken at the median 
vein. Reniform macula light-edged, with a light median streak, narrow, terminating iuAvards into a semicircle 
instead of the ring-macula. A distinct Avhite streak behind it at vein 4. Exterior line black, doiible, filled 
light, and with 2 dark lines, incurved in the submedian fold. White marginal lines from the apex downwards 
and from vein 4 upwards. Abdomen and hindwing of a purer brown. Everywhere in West and South Africa 
and the islands, apparently not in East Africa, but in India and the Australian islands. The specimens from 
Madagascar: — rectilinea Saalm. differ only in the exterior line being less sinuate in the submedian fold, and rectilinea. 
besides the interior line is directed from the inner margin more exactly towards the reniform macula, instead 
of a place somewhat imvards to it. 28—36 mm. 
E. cariei Joan. (8 h) may be a form of maillardi. Ground-colour more light violettish-brown. The cariei. 
basal and interior lines less white, the exterior line very indistinct, behind it narrowly distinctly dark. Margin 
brown without white lines, with dark dots. $ 33 mm. Mauritius. 
E. albivitta Hmps. Thorax and foreAving red-broAAUi and dark broAAur, someAAdiat greyish-Avhite in the alhivitta. 
basal half, a black streak at the base and a AAdiite triangle beloAV it. Interior line black, undulate. Reniform 
macula indistinct, elliptical, white, Acith a dark centre. Exterior line more excurved in front than in maillardi. 
At the costal margin before the submarginal line a darker spot than in maillardi. Abdomen and hindAving 
greyish-broAvn. $ 32 mm. Cape Colony. 
E. nigeriensis Hmps. The tAvo lines on the foreAAung Avhite, edged black inside and outside, the interior nige- 
line excurved as far as vein 1, then iiiAvards, the exterior line extending as in miranda. The tAVO maculae as nensis. 
well as the submarginal line somewhat like maillardi. The $ shoAVS a white spot behind the reniform macula. 
30—^34 mm. Niger District. — miosticta E. Provt, from St. Thome, is someAAdiat larger (32—36 mm). No AAdiite miosficfa. 
places at the apex and distal margin, less white at the submarginal line, the AA'hite places at the reniform macula 
are often absent. More intensely black, however, is the space before the interior line and also betiveen the 
exterior and submarginal lines. According to Prout, the position of the species at this place is vToiig, as the 
antennae are not thickened. The E, however, exhibits a hair-tuft on the second palpal joint, Aidiich may extend 
beyond the head in well preserved specimens.
