N. Borneo, Mt. Dnlit, December 1893 to January 1S94 (Hose); Malay Peninsula ; 

 Tenasserim, Dalgwiu, December IS'Jl (Bingham), foot of Donat Range, October 1N91 

 (Bingham). A specimen from the Salween valley, July LsSU (Bingham), has the 

 red spots M' — SM- of the underside of the hindwing large and confluent, while tlie 

 discal greyish blue bar M- — SM^ is divided at (SM'). 



The individuals from Tenasserim and Lower Burma connect E. delpliis co)icha 

 with rh'lphls f/elpkis. 



Nic6ville, Butt, of Imh, I.e., records it from the Donat range (January), the 

 Thoungyeen forests, Moulmein, and Perak; and Moore, Lep. Ind., I.e., says thai it 

 was caught by Major Adiimson at " Tavoy and Hpapoon in October and November," 

 and that Mr. Tucker also found it at Tavoy. 



Vollenhoven described this form from specimens from Java and Padaug, 

 Sumatra, but he doubted the correctness of the locality " Java." His figure 

 represents certainly the Sumatran example, as it does not show the distinguishing 

 characters exhibited by Javau specimens ; hence the name of eoneha is to be 

 restricted to the Sumatran form of delplii.i, from which the individuals from Borneo 

 and the Malay Peninsula do not differ. VoUenhoven's figure 3 is not correct in so 

 far as there is on the forewing one vein and one discal lunule too much ; the black 

 median bars SC' — R' on the forewing should stand in the same cellules as the upper 

 two yellow postdiscal dots. 



According to Martin and Niceville, I.e., E. delphis occurs in N.E. Sumatra 

 " from near the sea to the elevation of Bekantschan, but not higher. Though it is 

 met witli everywhere over a large area, it is never so plentifal as are C. dolon, 

 Westwood, and E. eudamippus, Doubleday, in Sikkim in the beds of streams in the 

 spring. As 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 places on forest roads ; also small pools and moist places on roads, 

 especially if there are any Pierinae assembled to suck up the moisture, with whom 

 the big Chara.ees always associates. In such spots will be found sitting in the 

 hottest sun perhaps half a hundred or more L'atopsilias and App/as hippo, 

 Cramer, and amongst them one Chara.ves delphis, numbers of similarly coloured 

 butterflies evidently afi'ording mutual protection. Dr. Martin's Javan collector Saki, 

 in consequence of this characteristic, used to call C. delplii.'i the ' Koepoe Raja,' 

 because it sat amongst the Pierinae like a Raja, surrounded by his followers. 

 C. delphis is not restricted only to big jungle, but is found on roads far from the 

 forests, if only there are assembled the protecting Pierinae." 



Dr. Hagen says of E. delphi.'i concha of N.E. Sumatra, l.<\ : " Ueberall, aber 

 nicht hiiufig, uud jetzt wohl mehr auf die Vorberge beschrankt. Mit Vorliebe auf 

 dem feuchten Sand an Furthen durch fliessende Wasser, oft mitten unter Schareu 

 von weissen Pieriden uud Fapilio antipkates, selir gem auch an fiber das Wasser 

 hereinhiiugeaden Zweigeu."
