434 L. de Niceville & Dr. L. Martin — Butterflies of Sumatra. [No. 3, 
Gayoe collectors brought this species in some numbers, it may perhaps 
be less rare in the north of Sumatra. No female has been obtained. 
The male is fond of fceces on forest roads ; also small pools and moist 
places on roads, especially if there are any Pierinse assembled to suck 
up the moisture, with whom the big Charaxes always associates. In such 
spots will be found sitting in the hottest sun perhaps half a hundred or 
more Catopsilias and Appias hippo , Cramer, and amongst them one 
Charaxes delphis , numbers of similarly-coloured butterflies evidently 
affording mutual protection. Dr. Martin’s Javan collector Saki in conse¬ 
quence of this characteristic used to call C. delphis the “ Koepoe Raja,” 
because it sat amongst the Pierinse like a Raja surrounded by his 
followers. C. delphis is not restricted only to big jungle, but is found on 
roads far from the forest, if only there are assembled the protecting 
Pierinse . Dr. Martin notes that in 1886 he gave up collecting for 
some time, till in August, 1887, when on his way to pay a medical 
visit at the Kloempang Estate, he saw at five o’clock in the evening a 
fine specimen of 0 . delphis , which was seeking a comfortable night’s 
lodging under the roof of a tobacco shed. As Dr. Martin was on 
horseback he could not catch the butterfly, but on shewing it to a 
passing Chinese coolie this man was so clever as to kill it without any 
damage by throwing a piece of wood at it. Dr. Martin took it home in 
his note book, and from that day commenced a new collection on pins, 
which is now in the Roval Museum at Munich, and of course includes 
this specimen which instigated his commencing to re-collect, and to 
which may also be due the production of this paper. 
254. ^Charaxes ( Eulepis ) schreiberi, Godart. 
Dr. Hagen informed Dr. Martin that he obtained this rare species 
from his Gayoe collectors. It would appear that the north-western 
boundary of our area is the head-quarters of the genus in Sumatra, 
as the Gayoes always brought in three or four times as many speci¬ 
mens of Charaxes as the Battaks did. C. schreiberi probably does occur 
in Sumatra, as it is certainly found in the Malay Peninsula, Java and 
Borneo. It is singular, however, that Dr. Hagen should have omitted 
it from both his papers. Dr. Martin picked up from the ground two 
forewings without body of this species in Fort Canning in the middle 
of Singapore. It is most remarkable how frequently the only record 
we have of this species is from single wings picked up in a similar way. 
It would seem to be that C. schreiberi is greatly persecuted by birds. 
255. Charaxes ( Eulepis ) kadenii, Felder. 
Dr. Wallace obtained the first known specimen of C . kadenii in
