Show 1893.] ME. E. Y. WATSON ON THE HESPEEIITLE. 77 to those of Iambrix, but the third joint is shorter. Shape much as in Iambrix, but the costa of fore wing is more arched ; vein 3 well before end of cell; vein 2 about equidistant from end of cell and base of wing ; vein 5 about equidistant from 4 and 6 ; upper discocellular minute; vein 11 starting about halfway between base of wing and end of cell, almost exactly opposite vein 2, strongly deflected upwards soon after its origin, and touching vein 12 for a short distance. Hind wing : vein 3 immediately before end of cell; vein 2 about twice as far from base of wing as from end of cell ; vein 7 shortly before end of cell; discocellulars oarely traceable ; vein 5 wanting. Male with a bristly tuft of hairs, springing from the base of the costa of the hind wing; there being also a distinct groove on the underside of the fore wing below the subcostal nervure to receive the tuft of hairs when the wings are closed. This genus is closely allied to Astictopterus, Iambrix, and Sancus, in the last of which vein 11 also touches vein 12 for a short distance ; the only other genus in which at all a similar character obtains is Cyclopides, but in this genus veins 11 and 12 altogether anastomose aud run confluent for the rest of their course. hector, sp. n 1. xanites, Butler 2. butleri, Wood-Mason and de Niceville ... 3. And two unnamed species. Confined to Southern Asia. KORUTHAIALOS HECTOR, sp. nov. Astictopterus xanites auctorum, nee Butler. Above dark fuscous. Fore wing with an orange-red fascia crossing the wing at the end of the cell, not reaching either the costal or inner margins. Hind wing without markings. Wings beneath as above ; the fascia on the fore wings being broader than above, and extending from close to the costa up to or slightly beyond the first median branch. The fascia on the fore wing varies considerably in extent, especially on the upperside, but on the underside never reaches the submedian and is never diffused along the inner margin as in xanites. Expanse 35 millim. (xanites expands 41 millim.). Occurs throughout Burmah and Malacca, and also in Java. This species has hitherto been confused with xanites, Butler; but the latter differs considerably on the underside of the fore wing, the orange fascia extending broadly as far as the outer angle and spreading along the outer half of the inner margin. Xanites appears to be a rare species, the only specimens I have seen being the type from Borneo and a single specimen from Malacca; this is apparently the species figured by Distant 1 as gemmifer, the gein-like spots of the true gemmifer (which is a Kerana) being omitted both from his figure and description. The species figured by Distant as xanites is the species here described as hector. 1 Ehop. Mai. pi. xxxiv. |
