424 L. de Niceville & Dr. L. Martin— Butterflies of Sumatra. [No. 3, 
214. Euthalia ( Tanaecia ) martigena, Weymer. 
Tanaecia mavtigena, TVcymor, 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. 
215. Euthalia nice'villei, Distant. 
One of the rarest insects of our fauna, Dr. Martin 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 (-) elone, de Niceville. 
E. (Tanaecia ?) elone, do Niceville, Journ. Bomb. Nat. Hist. Soc., vol. viii, p. 47, 
n. 7, pi. L, fig. 3, male (1893). 
Expanse : 9,3-1 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 hindwing. 
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.
