females. Both -sexes are very variable both in markings 

 and size. In the Raflles Museum series oi 25 males from 

 Bukit Kutu, all taken in xVpril 1915, the expanse of wings 

 varies from 68 to 100 mm.

Although this species is at once distinguished from the 

 next, midamns, by the presence .of apical v^hite spots in the 

 fore wing, nevertheless, as Fruhstorfer points out, its 

 relationship to that species must be very close. 



Apparently aegyptiis represents a group of island form§ 

 extending as far north as Singapore, but not occurring on 

 the Malay Peninsula i)roper, while midamiis is a continental 

 species, with a geographical race known as E. m. dejeani 

 extending down the Malay Peninsula as far south as Negri 

 Sembilan, but not so far as Singapore. 



The Malaysian subspecies of /s. aegijptns are : — 



E. a. aegyptus Butl, Borneo. 



E. a. sihgapiira Moore Singapore.

DistriJb. E. m. dejeani is the only form occurring in 



the Malaysian siibrogion. OHior subspecies occur in Siam, 

 Assam, Nepal and South China. 



The F.M.S. Museums series of 8 males and 1 female 

 shows an interesting gradation from the Siamese form with 

 blue gloss on the fore wings and reduced white sub- 

 marginal spots in the hind wing to another from Kedah, still 

 with the blue gloss but with larger white sub-marginal spots 

 in the hind wing, merging finally into examples from fur- 

 ther south in which the blue gloss practically disappears 

 altogether. 



A male in the Ratllcs Museum from Pahang goes one 

 step further in showing distinct traces of wliite apical spots 

 in the fore wing, thus approximating the last form discussed
