1895.] L. de Niceville & Dr. L. Martin— Butterflies of Sumatra. 533 
Dr. Martin informs me by letter from Munich that he possesses 
three specimens of a third species of Tapena which may perhaps be 
T. agni, de Niceville. As I have not seen these specimens 1 cannot in¬ 
clude them in the list. 
640. Odontoptilum angulata, Felder. 
Hagen as angulatus [sic]. Staudinger. The Achlyodes sura of 
Moore, described from N.-E. Bengal, is a synonym. 
641. Odontoptilum pygela, Hewitson. 
Both species of Odontoptilum are common, 0. angulata, Felder, at 
lower, 0 . pygela at higher elevations, and occur throughout the year. 
They frequent wet spots on roads, settling with wide-spread wings, 
0. angulata is called by the Malay collectors “ Koepoe Tai ayam, The 
fowl’s excrement butterfly,” which is a very good description of its 
appearance. 
642. * Astictopteeus jama, Felder. 
Grose Smith. Butler. Distant. I have never been able to identify 
this species which was originally described from a male from the Malay 
Peninsula. 
643. Astictopteeus olivascens, Moore. 
Isoteinon melania, Plotz, Berl. Ent. Zeitsch., vol. xxix, p. 230, n. 26 (1885); 
Astictopterus melania, id., Stet. Ent. Zeit., vol. xlvii, p. 110, n. 4 (1886). 
Hagen as olivescens [sic], and Isoteinia [sic] melania. Herr G. 
Weymer has sent me a coloured drawing of the type of “ Isoteinon ” 
melania in the collection of Herr Karl Ribbe. It appears to be the 
same species as Astictopterus olivascens, Moore, which latter species is 
not mentioned by Plotz in any of his papers, and appears therefore to 
have been unknown to him. I. melania was described from Malacca. In 
Sumatra A. olivascens is very common and ubiquitous throughout the 
year, and with Padraona dara, Kollar, is the commonest of our 
Uesperiidse. The males are very fond of the flowers of a wild Geranium¬ 
like plant and are found on every roadside and hedge. The dark uni¬ 
formly coloured butterfly has a pretty appearance when contrasted with 
the tiny red cup of the flower on which it is resting. 
644. Sancus pulligo, Mabille. 
Grose Smith as fuscula. Hagen as fuscula. According to Captain 
Watson, “ Tagiades ” fuscula, Snellen ( = u Astictopterus ’ celunda, Stan 
dinger), is, as far as is known, confined to Celebes, while S. pulligo,
