ITON; P1THAURIA. By Dr. A. Seitz. 
(japia. H. gupta Nic. Easily recognisable by the almost monotonously coloured under surface of the hindwing 
which only exhibits a lighter spot in the cells 2, 3, and 6, as well as an effaced lighter subterminal macular band. 
Described from Sikkim. 
deb His. H. debilis Elw. (171 e) externally resembles knywetti (173 h), but the arrangement of the small spots 
on the forewing is different; in the cell-end there is a double spot and the subapical row of spots is composed 
of 3 small spots. Beneath the ground-colour of the hindwing is paler and the submarginal row of small light 
spots is farther removed from the margin. From the Khasia Hills. 
abm. H. aina Nic. shows the hindwing beneath without any markings and originates from Sikkim. 
separaia. H. separata Mr. is distinguished by quite monotonously dull brownish-green hindwings beneath, without 
any markings. Sikkim, Naga Hills. 
albipecius. H. albipeclus Nic. (171 g). Easily recognised by the quite purely white hair of the thorax and palpi 
beneath. Described from the Shan Mts. 
decoraia. H. decorata Mr. (171 g). Recognisable by the bright chrome-coloured under surface of the wings, only 
the hind marginal half of the forewing being dark brown. Hindwing beneath with few brown punctiform spots. 
Above both wings exhibit in the proximal portions areas powdered with golden yellow on a dark brown ground. 
Only found in Ceylon in few places, for instance near Avisavella, the specimens figured were captured by Mr. 
E. A. Fairlie. 
honorei. H. honorei Nic., from the Nilgiris, and from Tritchina-Bali. Above cpiite similar to decorata , but here 
also the disc of the hindwing above is yellow, which colour gradually warms into the brown distal margin 
without distinct demarcations. Nilghiri Mts., Irichinopolis. 
masoni. H. masoni Mr. (171 f). Here the hindwing above exhibits in the disc one or several yellow spots which, 
in contrast to honorei, are distinctly defined; the one situate at the cross-vein is the largest and brightest. Burma. 
hyrtacus. H. hyrtacus Nic. (171 h) is above little characterised; on the blackish-brown forewing all the small 
hyaline spots in a large circle around the cell-end are as small as dots, besides them no other marking 
but the stigma extending in the <£ right across the submedian area; hindwing without any marking. Beneath 
the hindwing is traversed by a broad whitish median band; it is distally indistinctly defined, and in the dark 
clistal-marginal portion there are various small lighter spots. Otherwise it is similar to H. hrunnea (173 g). The 
type was taken on September 2nd in Pandalur in the Wynaad District in India; also known from Canara; 
the larva has been described in an Indian periodical. 
45. Genus: Iton Nic. 
Of the 3 species belonging hereto the $ of one species has a remarkable scent-organ, the d'd' of the 
others not. The species are easily recognised by the cell of the hindwing beneath being all white. The genus 
is otherwise evidently very closely allied to the Parnara. The range extends from the Himalaya to Indo- 
China and the Sun da Is. 
semamora. I. semamora Mr. (= barea Hew.), distributed from Sikkim across Indo-China to Sumatra, but appa¬ 
rently rare in many places. Chiefly distinguished from the following species by a large upright hair-tuft on 
the forewing beneath at the hind-margin, being absent in ivatsoni. On the hindwing beneath the whole cell is 
barea. white, and also the adjoining three cells are white excepting the apex. — f. barea Hew* from Sumatra and Pulo 
Laut, is a larger insular form with smaller white spots. 
umtsoni. !. watsoni Nic. (171 f) does not exhibit the above mentioned sexual mark of the $. On the hindwing 
beneath the veins are broadly powdered with whitish, the white cellular spots coherently extend almost to the 
hind-margin. Pegu, Shan Mts. 
azona. I. azona Hew. resembles semamora from which it is separable by the uni-coloured hindwing beneath, 
without the white discal band ; it also lacks the hair-tuft at the hind-margin of the forewing beneath. Described 
from Sumatra. 
46. Genus: Pitliaiirfa Mr. 
Allied to the preceding ones by the very strong, stout thorax, the head being likewise very broad and 
the forewing pointed. Hardly separable from Halpe, so that some (such as marsena) were sometimes ranged 
with Halpe and sometimes with Pithauria. Abdomen concial and relatively short, at the very pointed antennal 
club the apical end is turned backward. The cell of the hindwing is less than half the length of the wing, the 
distal margin of the wing is feebly curved . The basal portion of the forewing and the proximal half of the hind¬ 
wing are hairy like a fleece.
