Pubi. 16. VIII. 1933. CHLOROZANCLA, IOTAPHORA. By L. B. Prout. 77 
hindwing beneath about as in rafflesi. Macassar (Doherty), type £ in Mus. Brit.; “N. Celebes”, 1 May- 
June 1899, in Mus. Thing. 
T. waterstradti sp. n. (10 b). Rather bluer green than rafflesi, apical falcation scarcely so long, 
lobe at anal angle of hindwing scarcely more developed than in kina. Median area of forewing scarcely paler 
than the rest (only a little more blue). Underside bright orange-yellow, except on parts of the forewing, sub¬ 
terminal band of hindwing much interrupted, postmedian line of both wings, on the contrary, strongly 
red proximally. Mindanao (J. Waterstradt), type in Mus. Brit., ex coll. Oberthur. 
T. unipuncta replaces rafflesi in the Moluccas and New Guinea. Generally larger, with apical falcation 
still more produced, sexual dimorphism still stronger, hindwing with a dark cell-spot, followed by a zigzag 
white line, underside more strongly marked. — zoomesta Prout, from Ceram, differs little in the <$ from rare 
aberrations of the New Guinea race with the median area of the forewing narrowed, but has a deep-green $, 
only a little darker and duller than the — nieforensis Prout, from Mefor, is smaller than the other races, 
the median area of the forewing almost as green as the rest of the wing, the postmedian line of the hindwing 
obsolescent anteriorly, rather thick and ill-defined posteriorly. In some respects intermediate towards rafflesi. 
— unipuncta Warr. (10 c) from New Guinea, is large, especially in the 9> the apical hook of the forewing very 
strongly developed, the 9 purple-brown, with only small patches and suffusions of green remaining. 
Section B. Medium-sized, less densely scaled, yellower green, apices moderately produced (Mixochlora Warr., indescr.). 
T. vittata Moore (10 c) is the type of the group. It was described from N. India and has already been 
discussed in Vol. 4 and a closely similar Japanese race (prasinus Btlr.) figured under this name, vittata has 
the ground-colour slightly more yellowish, the bands more sharply expressed (more whitish), the ante- and 
postmedian generally less closely approximated posteriorly, the subterminal perhaps more sinuous. — suma- 
.trensis subsp. nov. is on an average larger, with both wings slightly more produced apically, and is still 
more sharply marked, with the postmedian band rather more proximally placed, the whitish costal area of 
the hindwing extended. Slopes of Mt. Korintji, S.W. Sumatra, 7300 feet, a long series collected by the Pratt 
brothers, the type in coll. Joicey. Specimens from lower altitudes on Sumatra, as well as from Malaya, are 
in some measure intermediate and perhaps better referred provisionally to the Indian race. alternata Warr., 
from the Philippines, has the bands almost parallel. 
T. argentifusa Walk, has conspicuous whitish streaks between the veins outside the postmedian line 
and has the subterminal more arcuate and the underside greener (less ochreous) than in vittata. Sarawak (type), 
Perak and Celebes, always rare. Differs from the New Guinea race in having the postmedian more distally 
placed, especially at abdominal margin of hindwing, the subterminal of the forewing more bent in the middle, 
that of the hindwing thick in anterior half, obsolescent posteriorly. — radiata Warr. (10 c), from Dutch New 
Guinea, is the only form yet known from the Papuan subregion. 
Section C. Hindwing strongly angled at 3rd radial; colouring not green (? gen. div.). 
T. discolor Warr. (10 c). Recognizable at once by the shape, coloration and characteristic pattern, 
which is in all essentials reproduced on the underside. Khasis, not common. 2 from Arizan, Formosa 
(YVTleman) perhaps repi’esent a race, with the olive shading rather more extended, the whitish spots of fore¬ 
wing between M 1 and SM 2 narrowed. 
T. energes sp. n. (10 c). Smaller than discolor, antemedian line rather more direct, paler-edged proxim¬ 
ally, distal blotch larger. Hindwing with distal margin less bent at 1st radial; perhaps a little paler in its distal 
part. S. W. Sumatra: Barisan Range, western slope, 2500 feet, October to November 1921 (type and 1 para- 
type); North Korintji Valley, 5000 feet, September to October 1921 (1 ^); in Mus. Joicey. 
37. Genus: Clilorozancla Prout 
Distinct from Tanaorhinus, with which Hampson united it, in the minute palpus, short tongue, more 
regularly arched costal margin of forewing and more rounded hindwing. Antenna of the $ pectinate to the 
apex. Forewing with 1st subcostal anastomosing with costal. Hindwing with 2nd subcostal arising from end 
of cell. Only one species known. 
C. falcatus Hmpsn. Quite distinct from any Tanaorhinus in its small size (28—31 mm) and grey-green 
grund-colour, variegated (especially in apical-costal region of forewing) with olive-yellow, the lines whitish, 
the extracellular of the hindwing broadened into a band. Sikkim (type), Bombay and Travancore. 
38. Genus: lotapliora Warr. 
This beautiful genus differs chiefly from Hipparchus in the shape, the iridescent scaling and the highly 
specialised scheme of markings. See Vol. 4, p. 18, where the sole Palaearctic species, admirabilis Oberth., has 
been differentiated from the genotype, which we now figure.
