58 HYPOBAPTA. By L, B. Prout. 
D. polyphaenaria Ouen. (= basiflavata Moore) (8 h). Thoracic crest enormously developed. The 
dark border of the orange-yellow hindwing and of both wings beneath is rather broad. Underside yellow 
proximally, the fore wing with a large cell-spot, which is separated from the border by a white patch; borders 
enclosing large white midterminal patches, which extend, though narrowly, to the hind angle. N. India. Also 
from Perak, Sumatra, Java and Borneo. 
D. para Sunnh. (8 h) is possibly a seasonal form of polyphaenaria, though very distinct in the 
white-mixed (sometimes wholly white) hindwing and underside and the much narrower, more or less incomplete, 
dark borders. Common in the Khasis. 
D. taiwana Wileman. (8 g). Wings of the rather broader than those of polyphaenaria, recalling those of 
the Japanese virescens Btlr. (vol. 4, pi. 1 g), the yellow suffusions of the hindwing and of the underside very 
much weakened, the dark borders as broad as in polyphaenaria, less constricted in the middle, but much less 
solid, more broadly and continuously displaced by the ground-colour distally. Formosa. 
D. marginata Warr. (9 a) Very near polyphaenaria. Hindwing with distal margin more rounded, brighter 
orange, with the border black, but much narrower, more uniform in width throughout. Underside (with venter) 
brighter orange, the black borders not enclosing white terminal patches; border of forewing twice as broad 
as that of hindwing. S. Celebes. Perhaps also from Borneo. 
*■ 
D. wilemani sp. nov. Allied to polyphaenaria. Forewing more densely irrorated with black; basal 
black streaks stronger, one on the 2nd submedian longer; postmedian line at least as strongly produced as 
in wytsmani (8 h), but not zigzag posteriorly, the pale spots beyond it ampler, shaded with a delicate pink, 
slightly recalling Terpna differens or thyatiraria ; apical patch, above and especially beneath, sharply pale; 
black subterminal streaks in cellules 2, 3, 4 and 5 developed, as in occasional aberrations of polyphaenaria. 
Hindwing shaped nearly as in polyphaenaria, only with the projection at the 3rd radial and 1st median slightly 
less noticeable; rather paler than in that species; the dark border filled-in with grey proximally (where poly¬ 
phaenaria shows the concavity) and terminally, so as to appear almost solid. Underside very much like some 
broad-banded polyphaenaria, the hindwing with the white margin nowhere very broad, but anteriorly reaching 
the 2nd subcostal. Formosa: Ivanshirei, 1000 feet, 2 September 1908 (A. E. Wileman), only the type known. 
D. subrosea Warr. (= subsimilis Warr.). Forewing with costal margin shouldered at base, then 
straight (genus Perissolophia Warr.) : much more weakly marked than the preceding group- the cell-mark linear. 
Hindwing above and forewing beneath pink, with olive-grey irroration, the latter with a dark line shortly beyond 
the cell-mark, angled at radial fold and not reaching the costa; hindwing beneath paler, except distally. Sikkim, 
very rare, only Warren’s two types known to me. The following species has since 1895 been misidentified 
for it. 
D. purpurata is less weakly marked than subrosea, the cell-mark broader, the lines more zigzag, a 
red-brown subapical patch developed on costa of forewing, the angled line just outside the cell-spot beneath 
wanting. Hindwing and underside pale, marked with pink at the distal margins. — purpurata Bastelb. (8 h) 
is smaller than subrosea, darker and duller, not very variegated. Formosa. — wytsmani subsp. nov. (8 h), erro- 
neosly figured in Wytsman’s ,,Genera Insectorum“ as subrosea, is larger, lighter, more sharply marked, underside 
with the cellspot mixed with black and the postmedian line fairly well expressed, the pinkish distal shades 
rather weakly developed. Sikkim (the type in my collection) and Bhutan. 
17. Genus: Ilypohapta Prout. 
Differs from Terpna in having the face less protuberant, the antennal pectinations of the longer, 
the forewing elongate, with distal margin strongly oblique, cel) fully y 2 , produced at its apex. Hindwing rather 
narrow, abdominal margin elongate, distal margin markedly crenulate. Thorax robust, with slight crests. 
Abdomen with short crests. Exclusively Australian. The early stages of the type species have been fully described 
by Rainbow. 
H. diffundens T. P. Luc. is possibly a small variety of the following species, but differs markedly 
in its much smaller size, paler grey colour, less crenulate and much more distally placed postmedian line, which 
moreover, on the forewing, is almost as remote from the antemedian anteriorly as posteriorly, and the close 
approximation of the subterminal band beneath to the distal margin; forewing beneath black in base of cell. 
The hindlegs are lost in the unique type. C'oomoo, Dawson River, type in coll. Tring Mus. 
H. percomptaria Guen. (8 i). The white ground-colour above is shaded with reddish and grey, 
somewhat as in Pingasa, but the distal area is almost concolorous. The black lines stand out sharply. The 
angled cell-mark is reproduced on both wings beneath, followed by a weak postmedian line, which is bent in 
front of the 3rd radial; blackish subterminal bands are present, but that of the forewing does not reach the
