cell, with a smaller one below it in the angle of vein 2 ; 

 catennlated band consisting of eight spots, the seventh and 

 eighth forming the angled spot and being quite confluent ; 

 spots 1 and 2 are shifted inwards, the latter^s outer margin 

 barely touching the inner margin of spot 3 ; spot 1 is smaller 

 than 2 (which latter is large and quadrangular) and is placed 

 on about its centre ; spot 3 is shifted right out from 2, 4 

 slightly further out, 5 and 6 inwards, 7 slightly inwards, 

 confluent with 8, and extending nearly up to the fourth spot 

 of the basal series ; a broad submarginal band as in the 

 primaries, but edged on each side with pale greyish white, 

 the sliglit lobe with a large deep black spot slightly encircled 

 with ]iale metallic-blue scales ; a similar black spot with 

 metallic-blue scales between veins 2 and 3, the marginal 

 space between the two being blackish, more or less covered 

 ■with jiale blue metallic scales. 



Expanse 56-57 mm. 



The type from Halmaheira is in my collection ; it is a 

 marked and very beautiful species, and will come between 

 A. padus, Feld., and el/eta^ Hew.; its much larger siz3 will 

 separate it from the latter, whilst the lustrous silvery pale 

 blue will separate it at once from the violaceous blue of the 

 former, besides which the under-surface pattern is different. 



Arhopala suhlustris^ sp. n. 



? . Both wings sublustrous violaceous blue. Primaries 

 with costa brown, of moderate width, apex broadly brown ; 

 termen brown, rapidly decreasing in width to vein 3, whence 

 to the tornus it is quite narrow ; an isolated dark spot at the 

 upper angle of the cell somewhat reniform in shape, beyond 

 which four somewhat ovate blackish spots, the second from 

 the costa being the longest, terminate the blue in that area. 

 Secondaries with very broad brown costa ; termen less broad 

 and decreasing to the tornus ; tail tipped with white. Under 

 suiface: both wings clear brown, with darker markings 

 palely encircled. Primaries with three increasing cell-spots, 

 with another small spot above the third on the costa and one 

 below in the angle of vein 2 ; a postmedial catenulated band 

 of seven confluent spots of nearly even width, the upper four 

 slightly curved, the lower three slightly shifted inwards ; a 

 subttrrainal band palely edged on each side. Secondaries 

 with four very small Lasal spots, the first shifted outwards, 

 and the third also but to a less extent, followed by three 

 small spots below each other, the second in the cell shifted 

 inwards, the third the largest and irregular ; a quadrate spot
