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



214. Ecthalia {Tanaecia) martigena, Weymer. 



Tanaecia martigena, Weymer, Stet. Ent. Zeit., vol. xlviii, p. 8, n. 6, pi. i, fig. 7, 

 female (1887). 



Weymer. Originally described from Sumatra. Occurs in the same 

 localities as the last, and is equally uncommon. 



2 J 5. Euthalia nice'villei, Distant. 



One of the rarest insects of our fauna, Dr. Mai-tin having obtained 

 only two specimens during the years he collected in Sumatra, and 

 Dr. Hagen none at all. Found at an elevation of not less than 

 3,000 feet. It probably escapes capture by the collectors as it is so 

 similar in general appearance to E. cocytus, Fabricius, and is thus often 

 passed over for that species. 



216. Euthalia ( ) kanda, Moore. 



Hagen. Originally described from Borneo. Dr. Martin has ob- 

 tained a few specimens at Selesseh, but it is very rare. 



217. Euthalia ( ) blonb, de Niceville. 



E. {Tanaecia ?) elone, de Niceville, Journ. Bomb. Nat. Hist. Soc, vol. viii, p. 47, 

 n. 7, pi. L, fig. 3, male (1893). 



Expanse : 2,31 to 32 inches. 



Description : Female. Differs from the male only in its larger 

 size, paler coloration on both surfaces, and on the underside in the 

 absence of the violet suffusion, especially on the himlwing. 



A very rare species, found only on the Central Plateau in July and 

 August. Dr. Hagen obtained this species before Dr. Martin, and sent it 

 to London for identification, but unsuccessfully ; nor was Dr. Martin more 

 fortunate in sending it to Berlin for the same purpose somewhat later. 



218. Euthalia garuda, Moore. 



Vollenhoven. Hagen. Staudinger. Whilst all the species of 

 'Euthalia abovementioned, with the exception of E. dirtea, Fabricius, 

 and also all that follow except E. adonia, Cramer, are more or less 

 inhabitants of the forest, this species appears only near human habita- 

 tions as the food-plant of the larva is the leaves of the mangoe tree, 

 which is always planted near villages and round houses. It is not 

 found therefore at higher elevations, as that fruit tree even at Namoe 

 Oekor does not flourish as it does in the plains. It is most plentiful 

 in January and February, when the males may be continually seen 

 pursuing each other from the shade of one mangoe tree to another.
