EUCORMA: OPISOPLATIA. By Dr. K. Jordan. 
P. euschemoides. cf and ? similar. Frons, collar, thoracic spots, breast, legs, underside of the 
abdomen and the broad marginal bands of the hindwing above yellow. Forewing more elongated than in 
the preceding species; the markings of both wings similar to those of the ? of P. camadeva. — The North 
euschemoides. Indian form, euschemoides Moore (5d), has the most yellow; on the forewing the yellow band is contiguous 
to the basal spot and the black spots in the distal half of the wing are sharply expressed. Sikkim; 
juvanicus. Assam. — javanicus Rothsch. (= javana Rob ., resumpta Dohrri) is distinguished by the smaller yellow 
markings in the basal half of the forewing, also the cell of the hindwing on the upperside has no distinct 
scotais. purple-black streak near the base. Mt. Gede, 4000 ft., Preanger; Sumatra (Dohrn). — scotais subsp. nor. 
(od). The patagia only yellow at the tip; the yellow markings on the forewing reduced, the non-contiguous 
basal spots widely separated from the band, the latter broken up into spots; hindwing with purple-black 
basal spot in the cell, in the cf the yellow, reduced even more than in Javan cfcf , but the margin in both 
sexes with 4 yellow spots between the 2. radial and 1. submedian. North Borneo. 
33. Genus: Eucornia gen. nov. 
Frons very strongly projecting; body thick. Antenna similar to that of Eterusia, but pectinations 
in the cf rather short, and the distal ones in the ? only a little longer than the middle ones. Forewing 
elongated; the l. and 2. subcostals free, the 3.—5. stalked, the 5. subcostal proximal, the 1. radial from 
the cell, the 2. and 3. radials stalked, upper angle of the cell widely projecting; hindwing distally broad, 
rounded, lower angle of the cell somewhat projecting, discocellular weakly angled, the 2. radial from the 
apex of this angle or arising somewhat before it, approaching the 3. radial, cf and ? alike. — Malayan 
species, which resemble Milionia (Geometrids) and Episteme (Agaristids). Forewing with a yellow or white band. 
intercisa. E. intercisa Moore (5 e). Two-thirds of the hindwing above and beneath with very strong green- 
blue sheen, as also the basal area of the forewing beneath, the wings otherwise black, a dark yellow band 
extending over both wings, straight on the forewing, on the hindwing posteriorly abbreviated and pointed. — 
Java. “Fluttered round the casuarinae of Hie plateau of Pengelengan in company with a deceptively similar 
Geometrid (Milionia) and was also not rare on the Tjikorai and other mountains” (Fruhstorfer Ms.). 
obliquaria. E. obliquaria F. (= eusemioides Fldr .) (5e). Black, antenna blue, abdomen ringed with white. 
Forewing with white band, sometimes interrupted in the cf, hindwing with large reddish yellow area, which 
is broadest at the hindmargin and has a black spot anteriorly which is sometimes very small; under surface 
with blue vein-stripes at the distal margin, and on the forewing also small whitish blue cell-spots. On Nias 
together with the ordinary form occurs a ? with much broadened white band, distinct blue vein-stripes on 
the upper surface before the distal margin and enlarged blue stripes and spots on the under surface, also 
the black spot of the hindwing is small (which also occurs in ordinary ?? from other places); this is ab. 
zebra, zebra BtJr. (= laja Pagenst.) (5f). — Java; Sumatra; Nias; Malacca; Borneo; Siam; Mergui. “Macassar” 
has been wrongly given as the habitat of eusemioides. 
euphaena. E. euphaena spec. nov. (5f). cf: body and wings velvety black. Antenna, head, some thoracic 
dots and the margins of the abdominal segments glossy blue. Forewing with broad yellow oblicpie band, 
which does not extend to the hinder angle, a line near the base, another before the middle, as well as 
streaks distally on the veins, all glossy blue. Hindwing with broad orange-yellow discal band, which is 
narrowest anteriorly and truncate posteriorly, some marginal streaks blue. Under surface more extended 
blue, the yellow bands paler; hindwing with blue crescent anteriorly at the inner side of the.yellow band. - 
Tondano, North Celebes. 1 cf in the Tring Museum. 
hampsoni. E. hampsoni Boll. Body black-blue, glossy in parts. Forewing black, with red median band from 
the costa to the hinder angle and violet-blue subapical macular band; hindwing above broadly glossy blue 
at the hindmargin. Beneath almost entirely blue; the bands of the forewing beneath more diffuse. — 
Buru; in coll. Holland. Not known to me in nature. 
34. Genus: Opisoplatia gen, nor. 
of: head, antenna and subcostal veins of the forewing similar to those of Encomia; the upper angle 
of the cell of the forewing not projecting beyond the lower, the discocellular deeply angled, the two arms 
of this angle of equal length, the 2. and 3. radials from a point; discocellular of the hindwing weakly 
angled close behind the 1. radial, the lower angle of the cell projecting somewhat beyond the upper, 
distance from the 1. to the 2. subcostal very much shorter than from the 1. median to the 2. median; the 
cell between the 2. and 3. submedians of the hindwing very much widened distally, at the margin about 
four times as broad as the preceding cell, and the latter twice as broad as the cell between the 1. and 
2. submedians, margin shallowly emarginate from the 1. median to the anal angle. — 1 species from Borneo.
