TERPNA. By L. B. Prout.

A. Antenna of <$ simple. Cells very short, hindwing with 2nd subcostal stalked (Caller emite-s Warr., 
gen. div. ?) 
T. subomata Warr. Expanse 66 mm. The blend of olive-green and grey colouring somewhat recalls suhornala. 
M. subradiata or ocellata (8 f) and the cell-spots are similar, but rather weak above, black beneath. Markings 
peculiar, a narrow green median band being concavely bounded very little beyond the cell-spot. Underside 
mixed with yellow proximally, both wings with an extremely broad, but ill-defined blackish submarginal band 
Sikkim, only the type known. 
B. Antenna of $ simple. Cells normal, hindwing with 2nd subcostal separate (Psilotagma Warr.). 
T. decorata Warr. (= dorsocristata Pouj.) has been described and figured in Vol. 4, p. 12, pi. 3 c, decorata. 
but belongs also to the Indian fauna, as Warren’s type was from Bhutan. 
C. Antenna of <$ with extremely short pectinations. Cells rather short. ( Absala Swinh.) 
T. pictaria Moore. Markings much as in decorata, (Vol. 4, pi. 3 c) but stronger, the cell-mark of the pictaria. 
forewing black and angulated, the subterminal markings also mixed with black, the subapical one very large, 
the one between the medians of the forewing obsolete. Apex less rounded. Khasis. 
T. dorcada Swinh. (5 c). Rounder-winged, quite distinct from any other species. White, irrorated dorcada. 
with olive-grey or green, the markings of the underside showing through in grey. Underside at base yellow, 
than clean white, with rounded black spots and subconfluent apical markings. Khasis. 
D. Antenna of 3 shortly to moderately pectinate. Cells very short. Wings ample, spotted beneath 
(Terpna H.-Sch.). 
T. haemataria H.-Sch. ( = almaria Guen.) (9 a). A large and robust species, with the underside haemataria. 
yellow at base, then heavily spotted with black: on the fore wing a longitudinal mark behind the cell, inter¬ 
rupted postmedian and terminal bands, the latter forming a large apical patch; on the hindwing a large spot 
in the cell and crossing the discocellulars, two costal spots and some elongate subterminal ones. N. India, 
not rare. 
T. subtrita Prout is closely similar to haemataria, especially above. The antennal pectinations appear subtrita. 
somewhat shorter, but the difference is very slight. Both wings beneath less yellow at base, the postmedian 
series of spots obsolete, etc. Formosa, the type from Kosempo; 4 SC from Kanshirei in coll. Wileman. 
T. ornataria Moore (5 c). Less large than haemataria. Pectinations less short. Forewing above ornataria. 
with more extended redbrown strigulation proximally and costally; hindwing with an additional black post- 
median streak between the 2nd and 3rd radials, reappearing as a rounded spot beneath. Underside with more 
strigulation and maculation anteriorly and basally than in haemataria, but with the postmedian and subterminal 
spots obsolete or much reduced. Darjiling (type) and Cherrapunji. 
T. pratti sp. nov. (5 c). Coloration nearly as in the preceding group*. Wings less broad, recalling pratti. 
those of the subgenus Lophophelma. Forewing marked much as in ornataria but rather more heavily, the cell- 
mark expanded, though not sharply defined, the postmedian band of the underside suggested by a broad blue- 
grey anterior half-band. Hindwing with stronger cell-streak and broader subterminal spot between the median 
veins than in the allies. Forewing beneath with the yellow at base less extended along the costa; cell-spot large; 
cell not darkened proximally (as in ornataria) nor with dark streak behind it (as in haemataria)-, postmedian 
band not or scarcely interrupted, except at abdominal margin. Hindwing beneath with three large spots 
representing the postmedian band and four representing the subterminal. S.W. Sumatra: Barisan Range, 
2500 feet, October—November 1921, 7 SC in coll. Joicey, collected by C., F. and J. Pratt. Also from Bukit 
Kutu, Selangor. 
T. leucomelanaria Pouj. occurs on the borders of the Palaearctic Region and has been dealt with in leucomela- 
Vol. 4, p. 12 pi. 1 e. It seems to connect ornataria and pratti with the Palaearctic species amplificata Walk. naria. 
(Subgenus B, Pachista Prout, contains only the Palaearctic species superans Btlr. and a close ally which I have 
recently described from E. China.) 
F. Antenna in S and rarely (neonoma) in $ pectinate. Wings rarely very broad, distal margins 
more or less crenulate, cell of forewing not shortened, underside with dark distal band (Lophophelma Prout).
