Show 576 MR. H. H. DRUCE ON BORNEAN LYCEENIDEE. [June 18, NIPHANDA, Moore. NlPHANDA RETER, sp. n. (Plate XXXII. fig. 12 d •) d. Upperside shining dark violet as in N. cymbia, de Nice'v., which it closely resembles. Underside: ground pure white with dark brown spots on the fore wing as in that species, but larger and more distinct, especially that one which lies beyond the basal streak, which is nearly twice as large as in N. cymbia. Hind wing with the spots arranged as in N. cymbia, but much larger; aud without the brown mottling of that species. Expanse lT 37y inch. Kina Balu ( Waterstr.). Mus. Staud. and Druce. At first sight the underside of this insect presents a very different appearance from N. cymbia, but on closer examination the spots appear to be similarly placed. The absence of all mottlings from the hind wing and the much larger spots, together with the pure white ground, should distinguish it. LUTHRODES, gen. nov. Allied to Talicada, Moore, from which it differs by the costal nervure of the fore wing being bent towards the first subcostal nervule, but entirely free for its wdiole length-not anastomosed as in that genus-and reaching the margin considerably before the apex of the cell. Type Polyommatus cleotas, Guer. I find on bleaching the wings that the species referred by myself (P. Z. S. 1891, p. 358, & 1892, p. 436) and others to Talicada are not strictly congeneric and present the differences in neuration described above. All the species of Luthrodes are tailless excepting L. minclora, Feld., which is tailed like J. nyseus, Guer. LUTHRODES MINDORA. Lyccena mindora, Feld. Beise Nov., Lep. ii. p. 277, t. 34. figs. 9,10 (1865). Cupido aruana, Druce, P. Z. S. 1873, p. 349 (nee Feld.). Talicada mindora, Distant & Pryer, Ann. Mag. Nat. Hist. ser. 5, vol. xix. p. 267 (1887). Labuan (Loiv); Sandakan (Pryer). The two specimens which I have seen from Borneo are now in Messrs. Godman and Salvin's collection. They were incorrectly referred to L. arruana, Feld., which has larger spots below and is without tails. They are identical with specimens from Mindoro before me. Of course in the general arrangement of the nervules Luthrodes scarcely differs from Lyccena, Cyaniris, and others, but the peculiarity of coloration seems to suggest a distinctive feature, being intermediate between those genera and Talicada. |
