NETROCORYNE; ODONTOPTILUM. By Dr. A. Seitz. 
1045 
(165 g), from Bernardmyo, is of a paler brown, the dents of the wings are still obtuser, the central dot on the 
hindwing is usually more distinct. - hampsoni Elio, c£- Edw. (165 g) is somewhat larger, the lowest subapical 
dot slightly removed towards the margin; Nilghiris, Ceylon. — Owing to anatomical differences in the genitals, 
all the 3 forms were regarded as distinct species. 
22. Genus: Xetrocoryne Fldr. 
This purely Australian genus contains but 1 species externally resembling a large Tapena, though the 
hind tibiae exhibit a small hair-lock, similar but smaller than those exhibited in other Australian Hesperid 
males (Casyapa calixenus etc.). 
N. repanda Fldr. (165 g) looks like a large Tapena, but it is of a brighter chestnut-colour, and beside 
the subapical spots there are in the forewing a group of large discal hyaline spots. In specimens from the 
northern parts of the range the hyaline spots of the forewing, are mostly larger than in the south. — Larva 
slate-coloured, the 2nd ring yellowish, the 3rd orange with black round spots on the sides of the dorsal line, 
on the 4th and 5th rings similar though square black spots. Anal end again orange with large black spots on 
ring 10, dorsal line white, centred with brown, lateral line narrow, orange. In a case of leaves on Callicoma 
serratifolia, Elaeocarpus reticulatus and cyanus. Queensland (Brisbane) and New South Wales (Sydney) in 
summer and autumn, not rare. 
23. Genus: Odoiiio|MiIui!i Nic. 
He-speridae of middling size with broad, lobate, very delicate wings, with very few and very small 
vitreous dots in the forewing, the hindwings being powdered with white. Palpi large and thick, forewing below 
the apex somewhat convex, the apex of the hindwing lobately produced with long fringes. — The larvae are 
rather short and stout, the head split at the vertex, but more transversely oval, with a less pointed mouth; 
the head is not glossy, as if it were varnished, like that in Tagiades, but clothed with fine short .yellowish-red 
hair. While feeding they sit quite freely, and only hide in resting between parts of plants that are carelessly 
drawn together, without rolling up leaves as the Tagiades do. They finally become milky white pupae without 
distinct appendages which are marked with fine rows of black dots and streaks, yielding the imago in the hot 
countries after a fortnight. The imagines rest on flowers with their wings widely spread, the apical portions 
of the forewings slightly hanging down, as in the American Eantis, the palearct-ic Thanaos etc. 
0. angulata Fldr. (= sura Wr.) (165 g). Distributed over Northern India and Southern China, but no 
more reaching to the palearctic frontier. Chestnut-brown, fore wing in the basal portion and centre with a 
mealy hue; hindwing traversed by a few white lines, the distal line forming a right angle towards the centre 
of the margin. Hindwing beneath white, at the apex and distal margin spotted brown. — subangulata Fruhst., 
from Bazilan, is said to be very much larger than continental insects; — in mail a bin a Fruhst., from Java, the 
white of the markings in the hindwing above is darkened pale yellowish-brown. — in sumatrana Fruhst. the 
red-brown and black bands are more distinct than in other races. — Larva pale ochreous-brown, the young 
larva yellowish-green; head dark brown, with yellowish-red hair. On Hibiscus tiliaceus, Urena lappago, 
Eriodendrum, and other plants. Pupa white with an obtuse cone of the head. The imagines are common in 
the sunshine, and with their wings far stretched out they rest on flowers, preferably on those of Lantana 
hybrida. 
0. helias Fldr. (165 g) is much larger than angulata, otherwise similar to it, but from the centre of 
the margin of the hindwing towards the hind-margin above the anal angle not a thick white line but a white 
stripe of about 1 to 2 mm width. The fringe in the anal portion of- the margin of the hindwing is long and 
snow-white. Celebes. — helisa Smpr., from the Philippines, is somewhat smaller and exhibits bluish-white 
scales on the forewing beneath before the anal part of the margin and near the base. Not rare. — hyperides Doll. 
may be a distinct species, very similar to typical helias, but the bands as well as the discal hyaline spots of 
the forewing are absent and the apex of the hindwing is broad dark. Sumbawa; collected by Fruhstorfer 
in Lombok at an altitude of 2000 ft., in April. 
0. pygela Hew. (165 g) is recognisable by the distinct white line growing thicker hindward, right 
across both wings. The whole anal portion of the hindwing is white, only before the margin traversed by a 
grey nebulous stripe; Borneo. — ragupta Fruhst. is a name for the Sumatran form with broader white bands. 
— javanica Fruhst. is smaller and has neater white bands; from Java. Not rare. 
0. leptogramma Hew. (165 li). Margin of the wing more uniformly bent, hindwing less lobate. Brown, 
hindwing through the centre broadly white. Philippines. Not rare.
