1895.] L. de Niceville & Dr. L. Martin— Butterflies of Sumatra. 533 



Dr. Martin informs me by letter from Munich that he possesses 

 tliree specimens of a third species of Tapenn which may perhaps be 

 T. agui, de Niceville. As I have not seen these specimens I cannot in- 

 clude them, in the lis b, 



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 through out 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. * Astictopterus 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 

 Pu uinsula. 



643. Astictoptbrus olivascens, Moore. 



Isoteinon melania, Plbfcz, 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 iu 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 

 Hesperiidse. 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 ( = " Astictopterus" eel inula, Stau- 

 diuger), is, as far as is known, confined to Celebes, while S. pulligo,
