Fruhstorker separates the specimens from Java under the name of Basilissa. 



Snellen has noted regarding this species : 



" Although Linnaeus, in some of his later works, confused the present 

 species with another Euploea (Super ba Herbst), it appears to be beyond 

 doubt, {vide Aurivillius, Rec. Crit. 1. c), that in the older work concerning 

 the Mus. Ludw. Ulr. a single species was described for which the Swedish 

 Professor cites Mulciber Cram, as the typical figure. The Javanese specimens 

 clearly differ, at least as regards the c?, from those of the South Asiatic Continent, 

 Malacca, and Sumatra (Mulciber Distant). They are somewhat larger, the 

 blue of the fore-wings is more purplish, their light spots are smaller, and the 

 median area contains less white. Tho white marking of the 9, moreover, is 

 somewhat finer. Midamus is a widely distributed species of which the following 

 are probably local forms : Diocletia Hbn. from the Philippines, Verhuelli 

 Moore from Nias, Mindanaensis Semper from Mindanao, and Gelderi Sn. 

 (DoNGO Doherty), from Flores.

One of the commonest butterflies of Java, occurring everj^where, in the 

 lowest-lying districts as well as in the higher mountains and likewise met with 

 in many other islands of the Malay Archipelago with but slight variation. 



A striking difference in colour exists in the two sexes, viz., that whereas 

 the c? entirely exhibits the Euploea type, in the 9 the process of colour evolu- 

 evolution, especially as regards the hind-wings, has evidently largely followed 

 the direction as it occurs in man)' species of the genus Danais, such as
