Show 568 MR. H. H. DRUCE ON BORNEAN LYCvENID^E. [June 18, Through the kindness of Dr. Staudinger I have been able to examine two specimens from Borneo, and the type of the species which was obtained from the island of Palawan. I find that the irregular dark blotches vary slightly in intensity and shape ; indeed, in neither one of the specimens are they alike in the corresponding wings. The species should be easily recognized, as it is quite unlike any other in the genus. It is a true Poritia, as defined by Mr. de Niceville. PORITIA PHAMA, sp. n. (Plate XXXI. fig. 18 d •) d • Fore wing, upperside brilliant greenish blue, apex and outer margin down to lower median nervule broadly black, then narrowly black; a quadrate black spot at the end of the cell adjoining the black costa and evenly bordered by the end of the cell, the third median nervule, and towards the apex by a short band of blue which is intersected by black nervules. Hind wing greenish blue, costal third and anal fold greyish ; a marginal row of small black spots between the nervules, most distinct towards the anal angle. Underside much like P. phormedon, but with the markings of a more reddish hue. Expanse lf^ inch. Kina Balu ( Waterstr.). I have a specimen before me belonging to Dr. Staudinger labelled " Vulcan Gede, West Java," which I take to be this species; it agrees exactly with Bornean specimens on the upper-side, but on the underside the bands are straighter and somewhat more compressed together, thus leaving broader ground-spaces, and are rather more reddish, but these are peculiarities which I have noticed in P. hewitsoni, Moore. PORITIA PHALENA. Poritia phalena, Hew. Trans. Ent. Soc. 1874, p. 344 ; 111. Diurn. Lep., Lye. p. 216, pi. lxxxix. figs. 14, 15 (1878). 2 . Simiskina solyma, de Mcev. J. A. S. B. vol. Ixiii. pt. ii. no. 1, p. 29, pi. iv. fig. 10 (1894). Labuan ( Waterstr.). d 2 • The male received from Labuan agrees exactly with Hewitson's type in the British Museum, and the female with Mr. de Nice-ville's description and figure of S. solyma, excepting that the discal spot is not quite so clearly white in any light. So far as I can tell the neuration agrees with that of Poritia, but the tuft of long black hairs attached to the base of the submedian nervure in the bind wing is wanting, and I notice that Mr. Doherty in describing a near ally, viz. P. hartertii, from Upper Assam, does not mention this patch. W h y Mr. de Niceville should place his insect (a female) in the genus Simiskina I do not know. Tbe sexes are remarkable for the disparity in size, the male before m e measuring li inch, the female ly7^ inch. The species has not been recorded since Hewitson obtained the type. |
