 n. 9, pi. tJ, fig;. 16, male (1S92). 



Originally described from the Malay Peninsula. I possess several 

 male specimens from Sumatra which agree "with the type. 



427. Arrhopala (Acesina) ammon, Hewitson. 



Originally described from Singapore. Occurs in Sumatra in the 

 Battak mountains. 



428. Arrhopala (MaJiathala) AMERIA, Hewiison. 



Hagen. Not uncommon ; as usual, the females are more often met 

 -with than the males. This genus is the one most largely represented in 

 Sumatra, which may perhaps be its head quarters, though the Malay 

 Peninsula may possibly possess quite as many species. All are found 

 in forests, but nevertheless their more or less metallic blue, purple, 

 and green colours are not at all conspicuous and they do little to 

 cull \eu the somber depths of the forest, as the restless species of 

 Lampid s do. Arrhopalas never come to small streams or damp spots 

 on roads to suck up the moisture, or to flowers, they hardly ever fly 

 unless disturbed, and as they always settle with folded wings, of which 

 the undersides present only dull brown, grey, or dull purple colours, 

 little is seen of them. They rest on leaves of shrubs of moderate 

 height, and never fly for any length of time or to a distance, feeling- 

 themselves much more secure when at rest. There is therefore only 

 one way to see and capture them, and that is to walk through the 

 underwood and disturb them by beating the bushes and low trees, and 

 thus to canse them to fly. The following species arc found only in the 

 mountains at high elevations: — A. azinis, de Niceville, A. azata, de 

 Niceville, A. teesta, de Niceville, A. anthelus, Doubleday and Hewitson, 

 A. ovomaculata, Hewitson, A. ammon, Hewitson, and A. morpMna, 

 Distant. All the rest occur in the plains. A. centaurus, Pabricius, so 

 common elsewhere, we have never seen in Deli, but Dr. Friedl Martin 

 took a single specimen at the Grading Estate in Indragiri, south of Siak, 

 in November, L894. The rarest species ait; ,1. amphea, Felder, A. anni- 



Hewitson, -I. diardi, Hewitson, and A. morphin i, Distant. Of the 

 three metallic green species none is common, but A. farquhari, Distant, 

 is less -.ace than A. h&rsfieldi, Pagensteoher, whereas A. trogon, 

 Distant, is the rarest of the three, Dr. Martin in thirteen years' collect- 

 ing having obtained only two specimens. 



429. Curetis malatica, Felder. 



Hagen. Originally described from Malacca.
