This widely distributed species appears to be of migratory habits, as I received in 1879 

 a specimen taken at sea during a cahn, thirty miles from Singapore and nine from the nearest 

 land.* If during a calm one of these butterflies can be found so far at sea, it can be easily 

 imagined that in such a region of sudden squalls and storms involuntary migration must 

 frequently take j^lace. 



Herr C. Piepers, whose interesting observations of butterfly life in Celebes have been 

 previously referred to, gives an interesting fact relating to this species :^" While I stood on 

 the bank of the river, which forms at this spot an apparently still and very clear pool before 

 entering the cleft in the rock, from which it reappears as a foaming and thundering waterfall, 

 a specimen of Papilio Hckmis, Linn., came flying over the water. Flying low, as is the habit 

 of this species, it came within a short distance of me, when I saw it suddenly half close its 

 wings and dive down close beside me, so that the whole body and about a third of the wings, 

 wliich slanted upwards, were immersed ; it then raised itself again out of the water and 

 flew away." f 



According to Mr. Wade, this species in Kandy, Ambogamua, and Kottawa forest, in Ceylon, 

 "frequents high jungle only." Whilst, on the same island, Mr. Mackwood describes it as "found 

 principally in open glades and roadways in the jungle, from about 2000 to 4000 feet." I 



I have received from Penang specimens of a large dragonfly and this species, labelled 

 respectively by the Eev. L. C. Biggs " pursuer and pursued."
