E. ypleta Swinh. The hyaline spots on the forewing large and wedge-shaped, taking up almost the ypleta. 
entire wing with the exception of the apex and two blackish streaks from end of cell to termen. I borax 
and abdomen black, spotted with brillant orange. Hindwings orange at inner margin, otherwise black-brown. 
Smaller than the preceding. Waigiu. 
E. lutulenta Snell. has head and body dark brown, marked with orange-ochreous. Abdomen with lululenia. 
broad rings. On the hindwings 4 rectangular, dull hyaline spots. From the Sunda Islands. The specimen 
figured on our plate (12 a) as lutulenta is not typical, but represents rather the form strepsimeris Meyr. from strepsimeris. 
Queensland. This, probably identical with xanthostacta Hmps. (appearing rather like a somewhat pale geographica), 
was by Hampson (Catal. p. 117) referred to as synonymous with lutulenta, but differs from it in the white 
tips of the antennae; moreover on the hindwing the basal hyaline spot which in typical lutulenta frequently 
is absent, is of equal size as the other three Rather common. 
E. confinis Wkr. differs from the figured form malaccensis Rothsch. in having on the forewing the ^g^msis 
hyaline spots united into one large transparent patch. — musa Swinh. refers to ?? with shorter spots above musa. 
and below rib 2 of forewing. — catoria Swinh. is the name given specimens with dark, unspotted hindwings. catoria. 
The species has a very wide range, extending from the northwesterly Himalayas, where it approaches the 
Palaearctic Region, throughout India to Ceylon and Burma, and as malaccensis to Malacca and Tonkin; catoria 
is found in Assam and Bhotan. — The South-Indian form intensa Rothsch. (12 b) has on the forewing the spots interna. 
farther separate, on the hindwing, however, united to one large transparent discal spot; the orange markings 
of abdomen very fine. 
E. subaurata Wkr. (12 b) resembles the preceding in colouring and markings, but is much smaller, subaurata. 
more so than Naclia punctata. Ceylon, where 1 took several specimens on sunny mountain-roads near Kandy 
They are very difficult to recognize, appearing like Diptera. 
E. geographica Meyr. (= detola Swinh.) (12 b). Size and forewings as in E. lutulenta strepsimeris, geographica. 
but hindwing with only one hyaline spot and an orange spot at the inner margin. Body less profusely 
marked with yellow. Eastern Australia, from Brisbane to the Richmond-River. 
E. affinis Moore (= politula Swinh.) Dark fuscous; thorax spotted with orange behind. Abdomen uffinis. 
on back and sides with rows of golden-yellow spots. On forewing below apex of cell an hyaline spot, 
reaching to the middle of the lower median; some spotlets at the apex of the cell and above base of rib 2; 
behind the middle, between ribs 3 and 7, a series of 4 spots, the second one from above small. Hindwing 
of cf with 1, of ? with 3 transparent spots. Andamans. 
E. megatorna Hmps. (9h) has the body spotted, and ringed with yellow as in the preceding species, megatorna. 
but on the forewings 4 semi-transparent spots within and below the end of the cell and below the apical 
portion of the costa, and a double spot before the middle of the terminal margin. The forelegs of cf with a 
heavy tuft of hair-scales. From Mackay (Queensland). 
E. angustipenna Luc. is almost identical with the preceding, but the spots areas a rule slightly larger, angusti- 
more transparent; cf lacks the heavy tuft of hair-scales adorning the forelegs of megatorna cf. Queensland. V mna - 
E. aperiens Wkr. (— moorei Btlr.). Typical specimens (from India proper, Ceylon and Sumatra) aperiens. 
differ from the figured form khasiana Rothsch. in having the forewings less profusely shaded dark. On the khastam - 
hindwings there appear besides the small hyaline spots on the inner margin two further ones between ribs 
2 and 5, and occasionally a fourth one at the lower angle of the cell. — Occasionally we find in India 
a mong typical aperiens ab. lydia Swinh., with still larger hyaline spots which unite to form one large patch, lydia. 
E. siamica Wkr. approaches in the markings of the forewing aperiens, particularly the form lydia, siamica. 
but the body is orange, the abdomen with 7 yellow rings. May be at once recognized among other Eressa 
by the queer shape of the wings, the primaries being protracted to a sharp point, the hindwings, however, 
quite rudimentary, only about 1 mm wide and 2 mm long, whereas the forewings are just as large as those 
of the preceding species. Unknown to me in natura; the figure reminds one somewhat of Ceryx diptera. (9f). Siam. 
E. semifusca limps. (12c), easy to recognize by the fine yellow markings of head and body; forewings semi f usca - 
hyaline in basal half, the remainder black. Hindwings with black costa. From Perak and Labuan (Berneo).
