[June 16 done in the island of Borneo, for out of quite a small number of the genus there are twelve new species, most of which are strongly marked forms. As I a m gradually preparing a monograph of the genus, it will be unnecessary for m e now to do more than enumerate and describe the species.-G. T. B.-B. ARHOPALA MEANDER, Boisd. Voy. Astr., Le'p. p. 76 (1832). One very magnificently marked (underside) specimen from the collection of Herr Bibbe from South-east Borneo. ARHOPALA TAMEANGA, sp. n., Bethune-Baker.

Upperside : both wings dark bluish purple, in some lights almost indigo colour, and having a brownish patch in a certain light, with an almost linear black costa and outer margin to the primaries, and on the secondaries a broad brown costa and very fine black outer margin ; abdominal fold grey; submedian area very densely clothed with brown hairs; tail black, tipped with white, lobe scarcely developed at all. Underside : both wings very warm ochreous brown, with darker spots margined with creamy. Primaries with three very dark, large, slightly increasing cell-spots, below the third being another equally dark rather large spot, over the third a small spot near the costa ; subdiscal area dark brown, with a slightly purplish tinge; submedian area pale; transverse branch composed of six oval spots, the first four outwardly oblique, each spot projecting beyond its predecessor, especially the fourth; fifth and sixth spots shifted well inwards and below each other; submarginal band indefinite, but fairly distinct. Secondaries rather darker than primaries, with a dark spot at the basal costal extremity, three dark basal spots below each other, and a fourth shifted right beyond the internal nervure; these are followed by three more spots below each other, the third being very large and irregular ; cell closed by a largish spot, below it being another connecting it with the lower of the three spots; transverse band consisting of eight spots, the second being large and shifted outwards on to its outer margin, the third shifted right out, detached, fourth further out, fifth inwards, sixth outwards; seventh angular spot well inwards (not detached), almost broken into two at the angle, and confluent with the long eighth spot; submarginal row very indistinct; anal spot black, with a very plentiful scaling of bright pale greenish metallic scales, with one edged above by a dark line to the internal nervure ; this line has some metallic scales therein. 2. Upperside: both wings pale bluish violet; primaries with broad brown costa, broader outer margin, and very broad apical area, cell closed by a darkish spot; secondaries with very broad margins all round, especially the costa. Underside precisely as in the male, but rather paler, and with the submarginal bands rather |
