(In sonu! specimens, and notably a Bornt an one in the collertitni of the British Museum, the jio.-drrinr 

 wings have the pale suhmai^inal sputa, as found in most females ; these are very faintly visible in Malaccan 

 male specimens in the same collection.) 



Female. Anterior wings above dark, glossy fuscous, with the basal area more or less suffused with 

 custaneons-red, with the bluish subapical fascia and subinarginal spots as ui male, but which are much 

 linger and paler in colour. Posterior wings fuscous, becoming paler towards outer margin (the outer 

 margin is sometimes dull ochraceous as in the specimen figured Tab. IX., f. 1), and with a aubniarginal 

 row of four white spots placed between the nervules, of which the first and smallest is placed above the 

 dl&GOid&l nervule, and the fourth is situate between the second and third median nervules (a fifth small and 

 faintly marked spot is found in some specimens between the third median nervule and submedian nervure). 

 These spots are very inconstant, being practically obsolete in the specimen figured (Tab* VI., f. 1).

This species or race is one which affords much difficulty and doubt as to its distinctive 

 position. I have neither seen nor received any male specimens from Province Wellesley, 

 though females are not uncommon from that district. The British Museum, however, 

 possesses several male specimens which were collected by Capt. Pin will in Malacca, but these 

 do not altogether agree with the Bornean typical specimen described by Butler. The difference 

 is principally that of faiutuess or partial obliteration of the snbmarginal white spots to the 

 posterior wings, but as this is a variable character in female specimens, collected in such a 

 limited area as Province vVellesley, evidence of which is afforded by the two figures here given, 

 I naturally predicate the same amount of variability in the other sex. Another peculiarity of 

 I), itiiftvxrctix is the considerable similarity of the sexes. 



Are K. discrqwis and K. nhjrescens but seasonal varieties of one species ? This is neither 

 impossible nor improbable, but can only he denied or affirmed by some local student who will 

 carefully breed both forms. It is the want of this information that makes the present study 

 and classification of exotic Lepidoptera of so empirical a character. 



* Mr. Bates has also stated that in a number of species of butterflies which he observed on the Upper AimiEons the 

 males were morn numerous than the females, in the proportion of a hundred to one. However, no universal ntle ill tins 

 respect obtains in the Hhopahrei-n, and the whole aubjoct lias been exhaustively discussed by Mr. Darwin, in his 'Descent 

 of Mm]' flitul edit, p. lir'O).
