384 L. de Niceville & Dr. L. Martin — Butterflies of Sumatra. [No. 3, 



female in the British Museum ; these are all the known specimens. Its 

 precise habitat is unknown. 



In Sumatra the species of Goelites are inhabitants of dense virgin 

 forests, are very shy, but settle often, and can only be captured by ap- 

 proaching them most gently and carefully. They always rest with 

 folded wings, and are not easily seen on the dark ground covered with 

 leaves of all shades in the dim recesses of the forest. Their shyness and 

 the difficulty of discovering and capturing them may be the real reason 

 why they are so seldom met with in collections. Dr. Martin is of opinion 

 that Neorina loivii, Doubleday and Hewitson, is a gigantic Melanitis, so 

 he would call the species of Gcelites the Melanitis of the forest. Being 

 true forest insects they exhibit a beautiful glossy blue colour (confer 

 Mycalesis orseis, Hewitson, ante No. 50). 



72. Lethe (Nemetis) minerva, Fabricius. 



Hewitson as arcadia. Grose Smith as arcadia. Snellen as arcadia. 

 Kirby. Apparently very rare in North-Eastern Sumatra, Dr. Martin 

 having obtained one specimen only from the mountains. It is far less 

 rare in Java. 



73. Lethe (Debis) mekara, Moore. 



Hewitson. Grose Smith. Hagen. Semper. Snellen. Common 

 everywhere in the plains, in the mountains, and even on the Central 

 Plateau ; the specimens from the mountains have the yellowish-red 

 colour on the uppeiside of the hindwing more extensive than those from 

 the plains. The insect is always met with near bamboos, on which the 

 larva feeds, and is even very common iu Bindjei. 



74. Lethe (Debis) chandica, Moore. 



Hagen. Very rare, in the higher mountains and on the Central 

 Plateau. Dr. Martin has not obtained more than ten or twelve speci- 

 mens during his long sojourn in the island. 



75. Lethe (Debis) darena, Felder. 



L. darena, de Niceville, Journ. Bomb. Nat. Hist. Soc, vol. viii, p. 40, n. 3, pi. K, 

 fig. 7, male (1S93). 



Very rare in the Battak mountains, and not found below 3,000 feet 

 elevation. Dr. Martin wishes to add: — "I cannot lose this opportunity 

 to present my compliments to my friend Mr. Lionel de Niceville for his 

 extraordinary entomological knowledge and keen insight in having seen 

 only the drawing of the very different female of Lethe darena in Dr. 

 Polder's Reise Novara, Lepidoptera, and from that being able to deter-
