Ind. etc. iii. p. 217 (1890). c3*. Upperside very dark uniform purplish black ; inner margin of fore wdng pale brown. Both wings sparingly dusted between the nervules on the discs with bright green scales which change to blue in some lights. Thorax and abdomen black, covered with greenish hairs. Two tails of about equal length, tipped with white, one on the submedian nervure, the other on the first median nervule. Underside as male. Kina Balu (Waterstr.). I have received several females from Kina Balu, which agree well with Mr. Distant's figure of the underside, but the outer margins above are very narrowly black, and the male described above which is in Dr. Staudinger's collection. The male agrees in neuration with the male Iraota, and has four subcostal nervules like it, whilst the female has but three. The lower discoidal nervule in both sexes originates from the upper discoidal, and in Mr. Distant's figure is incorrectly drawn, as also are the antennae. As has been pointed out by Mr. de Niceville, the name nila has already been used for a species of this genus by Kollar; but as his name is a synonym of /. timoleon, Stoll, it may be used for Mr. Distant's species. SURENDRA, Moore. SURENDRA PALOWNA. Amblypodia palowna, Staud. Iris, ii. p. 131 (1889). Amblypodia amisena, Druce (nee Hew.), P. Z. S. 1873, p. 354. Kina Balu (Everett); Borneo (Low). I have compared these specimens with the type of Dr. Staudinger's A. palowna from the island of Palawan, and find that they are identical. A. palowna can be distinguished from A. amisena, Hew., by the hind wing being notched only, in both sexes- A. amisena possessing one tail in the male and two in the female. The underside of the hind wing in A. amisena is thickly sprinkled with green scales towards the anal angle, whilst in A. palowna these scales are generally entirely absent. I am inclined to think, however, that when a larger series of these butterflies can be examined, these characters will be found to be insufficient to distinguish the two species individually or from Horsfield's A. vivarna from Java. Messrs. Godman and Salvin possess one female, obtained by Mr. Low, on which the purple gloss is entirely absent. ARHOPALA, Boisd. All the species here included have, with the exception of the well-known A. centaurus, Fab., and A. apidanus, Cr., been carefully compared wdth the actual type specimens, and besides these |
