Bastelb. (5 g), formerly placed in Neobcilbis, may be a form of ochreipicta with the aberrant venation. Postmedian 
line more sharply dentate, underside less ochreous. Formosa. 
A. subtepens Walk. (5 h). Closely like cristata, though commonly smaller. Structurally it differs in 
that the hindtibia of the <$ has a short terminal process. Underside with the black admixture in the submarginal 
band not reaching the costal margin. Borneo. Also from Penang and — though not commonly — the Khasis 
and Ceylon. 
A. cristata Warr. (5 h). Hindtibia of <$ with a hair-pencil, but without terminal process. Both wings 
beneath with a conspicuous red submarginal band, which is variable in width and is generally more or less 
overlaid with black except at its edges. — ab. subopalina Warr. has the band beneath predominantly or even 
entirely reddish. —- cristata is distributed in North India, Burma, Perak, South China and Formosa. On Hainan 
Mr. C. T. Bowring has bred it from a larva found on Thespesia populnea; the pupa was attached inside a partly 
rolled leaf. — subspoliata Prout is a large, ample-winged race from South India and Ceylon; submarginal band 
beneath without red admixture. The type was from the Nilgiris. —- nigrescentipalpis Prout has the palpus at 
the tip black or blackish, the foreleg mixed with black, the submarginal band beneath interrupted, predominantly 
black. South Celebes. 
A. farinosa Warr. (8 c) is distinguishable at once'by its greyer, scarcely greenish colouring and the 
absence of the reddish markings. Cell-spots beneath large, submarginal band scarcely indicated. Lahul, N. W. 
Himalayas, the type taken at 12, 300 feet altitude, in September. 
A. usneata Feld. (= hypoglauca Hmps.) (5 g). Distinguishable from the other green species by the 
less elongate abdominal margin of the hindwing, characteristic admixture of small whitish glaucous patches 
on the upperside, conspicuous black submarginal spots, grey-mottled underside, without dark submarginal 
bands, etc. Kashmir Vail ey to Sikkim. 
6. Genus: Aeobalbis Prout. 
This genus was erected for the few species which agree with Archaeobalbis in most characters but have 
the 2nd subcostal of the forewing stalked. The discovery, however, that A. ochreipicta Swinh. varies in this 
character and that one Ceylon aberration of A. cristata subspoliata has it just stalked, has rendered the genus 
scarcely tenable. 
N. elaearia Hmpsn. (8 b) resembles a large, weakly marked Archaeobalbis viridaria except in the 
broader, more rounded wings. Underside not orange, at most slightly tinged on the hindwing with orange. 
Khasis (type), Sikkim and Upper Burma. 
N. flavibasalis Warr. (? = bipunctata Th.-Mieg) (8 b). Paler grey-green than the allies, termen of 
the forewing and especially its postmedian line less oblique. The underside recalls that of a Pingasa or Hypodoxa, 
being yellow at base, then white, distally with a very broad black band, forewing with white apex and large 
black cell-spot. Java (type), Malaya, Borneo, Sumatra. 
7. Genus: Herochroma Swinh. 
Wing-form nearly as in Archaeobalbis viridaria. Second subcostal of forewing stalked as in Neobalbis. 
Abdominal crests undeveloped. Hindtibia of with long terminal process. Only one species. 
H. baba Swinh. (5g). Smooth green, without the strong irroration of the preceding genera. Underside 
somewhat orange, with the markings nearly as in A. cristata. Not uncommon in the Khasis; rarer about Darjiling. 
8. Genus: Actenocliroiiia Warr. 
Near Herochroma but with the <$ antenna ciliated, the hindtibial process wanting, the 1st subcostal 
of the forewing free (in Archaeobalbis, Neobalbis and Herochroma anastomosing or connected with the costal), 
the distal margin of the hindwing rounded. Also consists of only a single species. 
A. muscicoloraria Walk. (5g). Paler green than H. baba, the lines arising from costal spots, the post- 
median strongly oblique outward anteriorly. Underside whitish, the submarginal band broad and dark. De¬ 
scribed from Darjiling, where it seems to be fairly common, as also in Bhutan and Assam. I have seen one 
example from Perak.
