The type specimen of attains is a very broad-banded individual (cj), which 

 Felder found in the old collectiem of Van der C'aiicllen. As it does not agree exactly 

 with any of the other Javan examples we have examined, we were at first inclined 

 to attribute this ditference to a mistake as to locality ; but the individual also does 

 not agree with the examples from any other locality. The comparatively large 

 white snbmargiual dots of the hiudwing, above, it has in common with the ordinary 

 Java specimens ; the discal spot R' — R- of the fonwing is much shorter than in 

 Indian specimens with an equally wide baud ; the hiudwing is less produced anally 

 than in either the ordinary Java form or the wide-banded continental forms ; the 

 cell-bar of the forewing below has the same jwsition as in athamas athamas, pointing 

 towards the discocellular spot ; the red postdiscal spots of the hiudwing are thin — 

 especially spot ('— SC" is much thinner than iu other Java individuals,— but this is 

 attributable to the width of the band ; the admarginal sjiots of the underside of 

 the hiudwing are pale yellow as in athamas athamas, small and ill-defined, while 

 the tails are acute and slender as in Java examples ; the femora are black with 

 white scattered scales as in athamas athamas, athamas uraeus, and athamas acuttis ; 

 the body and wings beneath agree in general tint best with the North Indian 

 summer form. On Mount Gede, at about 4000 feet, Mr. Prillwitz obtained a form 

 which agrees with the type of attains in the black femora, the colour of the body 

 beneath and the general tint of underside of the wings, but has the band, which in 

 the type is 11 mm. wide at the internal edge of the forewing and lU mm. at the 

 costal margin of the hiudwing, only 10 and 9i mm. broad respectively ; moreover, 

 the yellow admarginal spots of the hindwiug below are as large as in ordinary Java 

 specimens, not so small as in the type, and have the deeper tawny-yellow tint of 

 the spots of the former. 



A specimen collected in South .Java by Mr. H. Fruhstorfer, at 1500 feet 

 elevation (Nov. Zool. V. t. XL f. 1, J), agrees fairly well with the Gede form, but 

 approaches in the paler imderside the ordinary Java specimens. Such specimens 

 show, however, that there is considerable variation among the Java athamas, and 

 hence we believe that the t3-pe of attains is really a Javan examjjle. The material 

 iu collections is mostly without the date of capture ; besides, there is little or no 

 material available for comparison from the mountains except Mount Gede, where 

 Prillwitz has collected, and is still collecting, Lcpidoptera ; hence we do not know 

 what kind of variation the different specimens from Java illustrate. If we have to 

 do with seasonal variation, the form with the white femora, silvery underside of the 

 wings, and elongate wings is most likely the dry-season form ; but then the wet- 

 season form would have the wider band, while, judging from the differences between 

 the seasonal forms of continental E. athamas, it should have, on the contrary, the 

 narrower baud of the two forms. The difference in the individuals would be more 

 satisfactorily explained if the broad-banded individuals with the dark femora and 

 less white underside represented a mountain race, while the specimens with the 

 paler underside and more elongate wings represented the lowland race. Or, it is 

 also possible that the difference in the specimens indicates only individual variation.
