470 L. de Niceville & Dr. L. Martin— Butterflies of Sumatra. [No. 3, 
426. Arrhopala asia, de Niceville. 
Arhopala asia, de Niceville, Journ. Bomb. Nat. Hist. Soc., vol. vii, p. 333, 
n. 9, pi. H, fig. 16, male (1892). 
Originally described from the Malay Peninsula. I possess several 
male specimens from Sumatra which agree with the type. 
427. Arrhopala ( Aeesina) ammon, Hewitson. 
Originally described from Singapore. Occurs in Sumatra in the 
Battak mountains. 
428. Arrhopala ( Mahathala ) ameria, Hewiison. 
Hflg'en. 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 
enliven the somber depths of the forest, as the restless species of 
Lampides do. Arrliopalas 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 cause them to fly. The following species are 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. morphina , 
Distant. All the rest occur in the plains. A. centaurus , Fabricius, so 
common elsewhere, we have never seen in Deli, but Dr. Friedl Martin 
took a single specimen at the Hading Estate in Indragiri, south of Siak, 
in November, 1894. The rarest species are A. amphea , Felder, A. anni- 
ella , Hewitson, A. diardi, Hewitson, and A. morphina , Distant. Of the 
three metallic green species none is common, but A. farquhari , Distant, 
is less scarce than A. horsfieldi, Pagenstecher, whereas A. trogon, 
Distant, is the rarest of the three, Dr. Martin in thirteen years’ collect¬ 
ing having obtained only two specimens. 
429. Curetis malayica, Felder. 
Hagen. Originally described from Malacca.
