summarises his agreement in the statement that butterflies "which are an easy prey to 

 currents of air, defy geological barriers, and, above all, that important partition which from 

 the tertiary era has been erected, or rather excavated, in the bottom of the sea, between 

 Australia and India/'

Male and female. Wings above fulvous -red ; neuration, apex of anterior and margins of both wings 

 dark fuscous, spotted and marked with white- Anterior wings fulvous-red; costal margin, apical third, 

 outer and inner margin, nervures and nervules dark fuscous ; the fuscous portion contains the following 

 white markings : — a small subcostal spot before end of cell, three somewhat larger spots just beyond end of 

 cell, and a transverse subapical Beries of six large spots, the upper two smallest and divided by second sub- 

 costal nervule, fourth and fifth largest divided by second discoidal nervule, sixth much smaller and rounded, 

 on the outer side of which is a smaller spot followed below by two still smaller ones ; and a marginal 

 Beries of small spots, becoming indistinct and obliterated towards apex. Posterior wing fulvoua-red ; 

 nervures, norvules, and outer margin dark fuscous, the median nervules very broadly so ; a submarginal 

 a (id marginal series of small white spots, and abdominal margin much paler, Anterior wings beneath 

 generally as above, but with a distinct white spot on inner side of fuscous margin between second and third 

 median nervules ; a distinct and continuous marginal and snbmargiual series of spots, and with the dark 

 shading paler and brownish, beyond the large transverse subapical spots. Posterior wings very much 

 paler than above; the nervures and nervules margined with very pale greenish, and with a distinct costal 

 spot near apices of costal nervure and first subcostal nervule. Head and thorax above dark fuscous, 

 spotted and streaked with white; abdomen fulvous-red above, a little paler beneath; sternum black,

This species has until quite recently been recognised by the name of D. phxippm, Linn. 

 It has, however, been shown by Hermann Streeker,* and also by Oodman and Salvin f f 

 that the name and description given by Linnfieus really applied to a well-known and widely 

 distributed species, which for a long time had passed under the designation of D. arcivipj)us. 

 As it is impossible for two species in one genus to be known under the same name, that of 

 Cramer must henceforth be applied to this insect. The only Javan specimen hi my collection
