Western Java at a high elevation in 1861, and very appropriately called 

 it " The Calliper Butterfly," since when only very few specimens have 

 reached Europe. In 1889 Dr. Martin found only one old and worn 

 specimen in all the larger German collections when visited by him, 

 which specimen is now in the Berlin Museum. The first in Sumatra 

 was obtained from the Central Plateau in 1892, where alone it is 

 found, and although Dr. Martin offered a special bonus of a dollar for 

 every further specimen, only seven in all were brought in. Nearly all 

 were captured on the faeces of Karbouw buffaloes, deposited on the 

 sandy river banks where the buffaloes used to drink. Herr H. 

 Fruhstorfer was sent to Java by the late Herr Honrath to collect 

 Hhopalocera, but with special instructions to look out for C. hadenii, 

 but he was not successful in getting it. Since then a retired non- 

 commissioned officer of the Dutch Indian Army settled in Java, Heer 

 C. E. Prillwitz, has captured eight specimens in Preanger. 



256. Charaxes (Eulepis) athamas, Drury. 



Snellen. Hasten as athamas and samatha. Mr. Moore described 

 C. samatha from Tenasserim, and afterwards recorded and figured it from 

 Ceylon. It is a synonym of 0. athamas, which latter is without doubt 

 the commonest of all the Charaxes in Deli, occurring from near the sea to 

 Bekantschan and Soengei Batoe ; females are very rare. The males are 

 very fond of moist places and fa3ces, to which they will always return 

 after being disturbed ; when frightened they retire temporarily to the 

 leaves of the higher trees well out of reach, and settle with folded wings. 

 On the wing they are not easily differentiated from the JBierinse, only 

 their flight is very much stronger and more rapid. 



257. Charaxes (Eulepis) hebe, Butler. 



Grose Smith. Butler. Staudinger. Kirby. Distant. Originally 

 described from Sumatra. 



258. Charaxes (Eulepis) moori, Distant. 

 Hagen. 



259. Charaxes (Eulepis) jaltsus, Felder. 



We have here to do with three very difficult species, or perhaps we 

 may say two, as C. jalysus appears to be fairly constant, though I am 

 not at all sure that it will not hereafter be found to gradually mero-e 

 into the two previously-named species. G. jalysus has the greenish- white 

 areas of both wings on both sides the largest of the three. G. moori 

 appears to be best distinguished from G. hebe by having the inner
