the Tipperside of both wings, and the breadth and length of the discal bauds of 

 the underside of fore and hindwing, serve especially to distingnish the various 

 geographical races. According to the width of bluish white scaling at the distal side 

 of the band of the forewing, and the breadth of the bands of the underside, one can 

 arrange the various subspecies into two groups : (1) a western group, including the 

 forms from the Malay Peninsula, Sumatra, Nias, Borneo, and Singajjore, having 

 the band of the underside narrow and the postdiscal scaling of the upperside of the 

 forewing extended ; and (2) an eastern group, in which the postdiscal bluish white 

 scaling of the forewing above is restricted, and the band of the underside wide. 

 The differences between the two groups are, however, completely overbridged: as (1) 

 the Singapore subspecies has the postdiscal scaling of the forewing sometimes 

 not wider than it is in certain eastern specimens, and sometimes as wide as in 

 certain Malaccan individuals ; as (2) the Nias form has the postdiscal scaling of 

 the forewing much extended, but the band of the underside broad ; and as (3) the 

 Lombok form, though agreeing on the upperside with the Javan form, has the band 

 of the hindwing below not broader than it is in many western specimens. It would 

 be quite arbitrary to regard one or the other of these insects as specifically distinct. 



The early stages of E. Itehe are not known; they are most likely not essentially 

 different from those of E. athamas. 



The habits of the imago are the same as those of E. moori, but very little is 

 known of either of the two.

Though the characters by which Herr Fruhstorfer differentiated this form from 

 the Sumatrau E. hebe hebe are by no means constant, there occnrriug specimens in 

 the Malay Peninsula which have the black postdiscal spots of the upperside of the 

 hindwiugs considerably smaller than certain Sumatrau iudividuals, the greater 

 ]iroportion of the specimens from the Malay Peninsula is nevertheless readily 

 distinguishable by the generally less extended bluish white scaling on the forewing 

 at the outside of the discal band proper, the larger, often confluent, postdiscal black 

 patches of the hindwing, or, if these patches are small, by the presence of two such 

 patches proximally of the white submarginal spot S('- — K', by the more distinctly 

 blue scaling near the black patches, and the less white admarginal spots. In our 

 single ? (from Batang Padaug) those black postdiscal spots are longer and much 

 better marked than in our single S from the western end of Sumatra (Setinjak, 

 W. Sumatra), but smaller than in the 2 ? ? from the eastern end of the island 

 (Palembang district and S.W. Sumatra) we have compared. 



Herr Fruhstorfer gives, besides Perak, Singapore as a locality where this form 

 occurs ; that is most likely incorrect, as " Singapore " is said by Herr Fruhstorfer 

 to be inhabited by E. hebe plautus ; Herr Fruhstorfer received the specimens from 

 the Museum at Singapore, and labelled them " ex Museo Singapore."'
