Sumatran specimens of that subspecies excepted which are specially mentioned 

 under d. 



?. Wings above olive tawny, variable in the depth of the olive tint. 



Forewing: median bars SC"^ — R^ and upper part of bar D merged together to a rather 

 large triangular patch, to which is joined the median bar W — R' ; discal band 

 varying from creamy white to pale buffish yellow, ochraceous beyond SM^ ; discal 

 bars R' — SM- rather thin, dark tawny olive, not black ; postdiscal interspaces 

 SC* — SM^ all marked as a rule, but interspaces SO* — R' and R^ — R' sometimes 



absent. Hindwing : postdisco-submarginal patches closer to outer margin than in 



polyxena repetitus, their proximal portions at least vestigial, that of patch R' — R'' 

 well marked, hence this patch especially larger than in repetitus. 



Underside similar to repetitus, but the brown median band of forewing 

 anteriorly limited by cell-bar 4 and median bars SC^— R^ while in repetitus the 

 interspace between median bars SC — R^ and bar D is buff colour ; hindwing with 

 two tails, the first strongly dilated at end, 8 mm. long, the second curved costad, 

 obliquely and obtusely cut off, 6 to 7 mm. long. 



Length of forewing : $, 36 — 41 mm. 

 ?, 43—45 mm. 



Hah. Java. In the Triug Museum 18 cfc?, 5 ? ? from: "Java" (type of 

 scylax) ; S. Java, 1500 ft. (H. Fruhstorfer) ; Mt. Gede, 4000 ft. (Prillwitz) ;

The ? described by Felder as that sex of amycus and said to be from Celebes 

 agrees with the ¥ ? of baya, and is certainly a Java specimen.

cj. We cannot find any constant character by which to distinguish all the males 

 from the Malay Peninsula, Sumatra, the Natuna Islands, and Borneo from the 

 continental Ch. polyxena hierax S-f. corax. Major Fawcett described individuals 

 from the Battak Mountains, Sumatra, as a new species, Ch. ajax ; we have 

 compared a number of specimens from that locality, but failed to see that the 

 greater percentage of them were any more different from the examples from the 

 lowlands of Sumatra or from Borneo than the specimens from either of these latter
