84 MR. G. T. BETHUNE-BAKER : A REVISION OE THE 



duller and purpler and non-lustrous blue, whilst below the pattern is quite different. 

 It is rare in European collections, and as the male has never been figured, I have 

 thought it well to do so now. 



Arhopala selta (Hewitson). 



Amb'ypodia selta Hewitson, 111. Diurn. Lep., Lye p. 14. n. 92, pi. iii«. figs. 3G & 37 (18G9). 

 Satadra selta Moore, J. A. S. B. vol. liii. pt. 2, p. 38 (1884). 

 Arhopala selta de Niceville, Butt. Ind. vol. iii. p. 245. u. 798 (1890). 



llab. Moulmein ; Mergui ; Tcnasserim. 



Expanse, 6 , 38 mm. 



This species is not unlike a small specimen of cigala Hewitson, but it lacks the 

 strong purplish tint of the underside, which is replaced by a much more subdued pink, 

 and the pale lilac washing is totally absent ; in the secondaries also the transverse 

 band is quite disconnected from the upper two spots and is shifted well out from them 

 and the spot closing the cell. Agala is also a decidedly larger insect and is more 

 purple and duller in tone, whilst the black margins are much narrower, especially in the 

 secondaries. 



In de Niceville's collection are several specimens from Tenasserim, and one female 

 in which the blue is bright lustrous cobalt. 



Arhopala brookei, n. sp. (Plate I. fig. 29, d .) 



Hal. Pulo Laut ; Borneo. 



Expanse, 6 , 40-44 mm. 



d . Upperside : both wings very deep indigo-purple, nearly as dark as in lazalus 

 Hew. ; primaries with a very fine black costa and the finest black linear outer margins ; 

 secondaries with broad brown costa and fine blackish outer margins ; tail fine, white- 

 tipped ; abdominal fold brownish grey. Underside : both wings dull brown with slightly 

 darker markings, faintly and palely encircled. Primaries with all the markings very 

 obscure, three small increasing cell-spots, below the third a smaller one in the lower 

 median angle ; transverse band composed of five spots, the first three outwardly 

 oblique, the fourth shifted inwards, below which is the fifth, shifted outwards ; sub- 

 marginal row indistinct ; submedian area paler. Secondaries with an indistinct spot 

 at the basal extremity of the costa, four basal spots below each other, the third shifted 

 outwards, followed by three larger spots below each other; cell closed by a subquadrate 

 spot, below which is a small spot in the lower median angle ; transverse band composed 

 of eight spots, the second one much larger than the first and touching the spot 

 closing the cell, third shifted right outwards and detached, fourth outwards again but 

 with an inclination inwards, fifth inwards, sixth outwards, seventh angular spot right 

 inwards and detached, and practically confluent with the long eighth spot; submargmal 

 row rather indistinct, darker over the pale sky-blue metallic scaling at anal angle.
