18. Genus: Hyarotis M. 
The species forming this genus is distinguished by a more brightly marked under surface. As to the 
genus itself cf. Vol. I, p. 343. 
H. adrastus Cr. (Vol. I, pi. 86 g, h). According to Fruhstorfer, Cramer’s figure represents a 
South Indian specimen (presumably from Ceylon); the author’s statement ,,Surinam“ is of course a mistake. 
But South Indian specimens vary just like those from other patriae to a great extent in the distinctness and 
extent of the spotting on the hindwing beneath, so that some may hardly differ from Sikkim-specimens which 
have been separated as praba Mr. (= phoenicis Hew.) (169 a, b, as adrastus). — meluchus Fruhst., from Java, 
has larger white spots which are smaller in palawensis Frulist. from Palawan; in the latter form the bands of 
white spots on the hindwing beneath may almost disappear. — In mindanaensis Fruhst.. from the Philippines, the 
band of white spots on the hindwing beneath is particularly broad. Larva whitish-green with darker longitudinal 
lines, head yellow with the black marking of a reverse Y; it spins together leaves of Rotang and Phoenix Palms. 
Pupa in front and behind tapering, dull green, on the dorsal sides somewhat marbled. It often yields the imago 
already after 8 days. The imagines fly singly, though not rarely, and prefer drinking from blue Leguminosae 
and the blossoms of Lantana hybrida. I took the species also in Hongkong. 
19. Genus: Isoieiiioii Fldr. 
Cf. Vol. I, p. 343. The genus consists of but 1 species being predominantly palearctic. 
I. lamprospilus Fldr. (= vitrea Murr.) (Vol. I, pi. 86 h). Fruhstorfer reserves the name vitrea 
for Japanese specimens which he separates from continental ones. The latter occur from Southern China through 
Indo-China to Tonkin where they are yet common near Chiem-Hoa, at an altitude of 1000 ft in August and 
September. — In Formosa another form occurs: formosanus Fruhst. It is smaller than the continental race, 
the white hyaline spots of the forewing and the dots on the under surface of the hindwing are considerably 
reduced. Under surface of both wings darker, more moss-green than yellowish. 
20. Genus: Isma Dist. 
The 5 species forming this genus have the approximate exterior and the monotonous brown colouring 
of species of Parnara, but the hindwings are larger, broader, and also in the slightly extended in the 
anal portion. The antennae are rather long with a moderately thick club gradually swelling up and then down 
again. In the forewing 12 terminates before the cell-end, in the hindwing 7 rises before the cell-end; hind tibiae 
bare with 2 pair of spurs. In the <$ the forewing shows an oval scent-spot behind the base of the cell, being 
more distinctly prominent beneath. Still more remarkable than this scent-organ is a very considerable 
prolongation of the fringe at the anal portion of the hindwing. As the genus Isma was not sharply characterized 
by its author, Watson sets up the name Lophoides for it with lapis as its type, whereas Distant founded his 
genus on obscura. 
I. obscura Dist. (169b) is a unicoloured brown Hesperid from Singapore with loam-coloured hair 
on the body and the basal parts of both wings. Beneath the wings are yellowish-olive, between the whitish 
spots of the forewing black shadows; between the veins of the hindwing brown punctiform spots. 
1. protoclea H.-Schaff. (= iapis Nic.) (169 b) somewhat resembles above Hyarotis adrastus, but the 
white spot at the lower cell-angle of the forewing is more comma-shaped, at least in the type (which however 
is without the antennae). Burmah, Malacca. — vulso Mob. (169 b) is so similar to protoclea that Snellen united 
them; but in vulso the white spots around the cell-end of the forewing are somewhat larger. Java, Bali, Sumatra. 
I. purpurascens Elw. & Ediv. (169 c) chiefly differs from protoclea in the hyaline spots of the forewing 
being also smaller in the $, and in the long fringe at the distal margin of the hindwing being blackish-brown, 
whereas in protoclea it is lighter and thinner; the hindwing exhibits beneath a slight violet hue. Pulo Laut. 
I. binotatus Elw. & Edw. (169 c) is recognisable by the disc of the hindwing beneath showing 2 very 
small white dots. Borneo (from the Kina Balu).
