Show 418 MR. J. H. LEECH ON T H E B U T T E R F L I E S [May 3, down its centre with paler scales ; beyond this patch is a circular black spot ; a black double spot occurs in the cell, beyond which are two large black patches touching the costa ; margins of all the wings black ; an irregular black submarginal band runs round all the wings, dividing near the anal angle and enclosing; two circular spots of the ground-colour; veins deeply marked with black, especially near the outer margins. Underside-markings of the fore wing reproduced, with the addition of a white costal mark, and six white spots about the apex : hind wing-all the veins broadly marked with black ; the ground-colour replaced over a great part of the surface by dirty white. Underside of the abdomen white. Allied to Castalia (nom. prseocc, Moore) diehroa, Koll., and chandra, Moore, both Himalayan species. I managed after much difficulty to secure a single male, which was flying strongly about some oak trees at Chang-Do, south of Gensan, Corea, beginning of July. 68. EURIPUS COREANUS, nov. sp. (Plate XXXVI. fig. 1, 6 $ •) Expanse, S 4\, $ 5 inches. Wings of male dark brown, the basal half suffused with purple; a straight white streak, originating at the base of fore wing, traverses about \ of its width ; a submarginal row of spots runs round all the wings, terminating at the anal angle iu a bright carmine elongated spot; the discal area of both wings is traversed by two series of spots arranged irregularly, but concavely to the base of the wings, besides which there are two (sometimes three) spots near the apex of the fore wing and near the anal angle of the hind wing, situated inside the submarginal band. The two discoidal spots are often confluent. All spots situated on the purple colouring are pure white, those on the remainder of the wings pale yellow. Wings of the female dark brown, spotted as the male ; all the spots about the costa and disk of both wings white, the remainder pale yellow ; anal lunule carmine. Underside of both sexes-fore wings black ; costa, apex, and outer margin pale bluish green, all markings of the upper surface reproduced; hind wings pale bluish green ; veins very prominent, markings of the upper surface reproduced, mostly bordered with black ; anal lunule carmine. The underside of this species is sufficiently distinct to prevent any possible confusion with Euripus charonda. I took a large series of both the species (one in Japan, the other in Corea) and they seem to be quite constant. This insect occurs commonly in a large forest about 15 miles south of Gensan in July; it frequents the tops of trees, and is very difficult to take in good condition on account of its powerful flight. 69. EURIPUS CHARONDA. Euripus charonda, Hew. Ex. Butt. iii. t. 4. fig. 1 (1863). This large species is common about Yokohama, Lake Biwa, and the province of Kaga ; it flies very high, only occasionally descending, like Apatura. |
