.1895/] L. de Nicevillo & Dr.' L. Martin— Butterflies of Sumatra. 45 L 
319. Una usta, Distant. 
Habitat : Cacliar; Myitta and the Daunat Range, Tenasserim, 
Burma; the Malay Peninsula ; N.-E, Sumatra. 
Expanse : $ , *95 of an inch. 
Description : Female. Upperside, forewing with the costa, apex, 
and outer margin broadly brown, the posterior half of the discoidal cell 
to the inner margin delicate cerulean-blue,. which becomes sligditly 
darker towards the base of the wing. Hindwing brown, with the ex¬ 
ception of a linear spot in the outer half of the discoidal cell, which is 
covered with bluish scales. Underside, both wings as in the male, only 
somewhat paler. Cilia grey-brown. Abdomen on the underside yellowish- 
white. 
Found in Sumatra at Bekantschan and in the Battak mountains 
from whence the unique female described above in Dr. Martin’s collec¬ 
tion was captured in December, 1894. It is never common, but is more 
plentiful on the river banks at Soengei Batoe in August and September 
than elsewhere. 
320. Neopithecops zalmora, Butler. 
To the synonyms of this species already given in Butt. India, 
vol. iii, p. 53 ( Pitkecops dharma , Moore ; Parapithecops gaura , Moore; 
•and Neopitheeops horsfieldi , Distant), may now be added Cupido talmora 
Druce, Proc. Zool. Soc. Bond., 1873, p. 318, n. 4, from Borneo (this 
species appears to be a MS. name of Mr. Butler’s which was never 
published), and Plebeius lucifer , Bober, Iris, vol. i, p. 61, pi . iv, fig. 5 
(1888), from the Aru and Key Isles, of which Herr Rober has kindly 
sent me a specimen from Aru. In Sumatra it is found over our whole 
area, in the plains (Stabat) and in the mountains (Bekantschan), but 
is never as common as P. hylax , Fabricius. The female, says Dr. Mar¬ 
tin, possesses on the upperside of the forewing beyond the discoidal 
cell a faint blue patch similar to that in the same sex of P. marise, 
de Uiceville. 
321. Spalgis nubilus, Moore. 
Originally described from the Andaman Isles. It may be known 
from the common Indian and Ceylonese 8-epius, Westwood, by the 
discal spot on the upperside of the forewing in the male being ochreous 
instead of whitish ; the female of S. nubilus is marked like the male, in 
S- epius the female has the disc of both wings on-the upperside more or 
less whitish. S. nubilus is also found in Burma, Java, and Borneo. Mr 
Moore has incorrectly recorded S. epius from Mergui, Lower Burma 
the species should bo S. nubilus, which occurs in Burma as far north
