[June 18, this interesting and rare species, which I have described above. 1 find it impossible to make out the neuration correctly without clearing the wing of scales ; but the possession of the tufts of hair seems to show that it is closely allied to Poritia, next to which I have placed it. The type in the Hewitson collection, which is in poor condition and has lost its abdomen, is the only female I have seen. On the underside the markings are somewhat like those of Poritia, but the wings are less thickly covered. PORITIA, Moore. W h e n Mr. Herbert Druce wrote his list of Bornean butterflies, one species only of this beautiful group wras known from the country, but shortly after Hewitson described twro (1874). I am able to include four new species, which, together with representatives of species described principally from other localities, brings the number up to about ten. PORITIA SUMATR^E. Pseudodipsas Sumatra;, Feld. Reise Nov., Lep. vol. ii. p. 259, pi. xxxvi. figs. 24-26 (1865) ; Druce, P. Z.S. 1873, p. 351. Labuan (Low). A single male in Messrs. Godman and Salvin's collection is my only authority for including this well-known species. PORITIA PHORMEDON, sp. n. (Plate XXXI. figs. 16 J, 17 2 •) d • Upperside brilliant emerald-green, closely allied to P. hewit-soni, Moore, from which it differs by the fore wing possessing a broad, arched, green streak along the upper w7all of the cell, extending from the base nearly to the end, sharply defined at its extremity; the black spot in the submedian interspace is large and prominent. Underside greyer, with tbe bands broader and more regular, and with their edges less distinctly prominent. 2 . Upperside : fore wing entirely without the ochreous which is usually present in that sex of P. hewitsoni, and without the brown streak which is usual in the submedian interspace of that species ; the blue streak in the cell as described in the male is very prominent, and is entirely absent in P. hewitsoni: hind wing with a small ochreous streak in the cell at its outer extremity. Underside as male, but paler. Expanse, d 2 > l/u incn- Kina Balu (Waterstr.). Mus. Staudinger. P. phormedon is the Bornean representative of P. hewitsoni, and presents sufficient differences to be considered distinct. It is also a much larger insect. Dr. Staudinger writes m e that he has only received a pair. PORITIA PELLONIA. Poritia pellonia, Distant & Pryer, Ann. & Mao-. Nat Hist ser. 5, vol. xix. p. 265 (1887). |
