18 imOPALOCERA MALAY AX A. 



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 series of six large spots, the upper two smallest and divided by second sub- 

 costal uervule, 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 

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

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

 and 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 snbmarginal 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, 

 spotted with white ; legs black ; under surfaces of palj:)!, trochanters, and femora white. 



(A variety in which the posterior wings have the fulvous-red much suflused with white is not 

 infrequent, and is represented by fig. 3). 



Male with a broad subovate scent-gland situated on posterior wing adjoining third median nervule. 



Exp. wings 73 to 90 millim.

This species has until quite recently been recognised by the name of T>. plexippus, Linn, 

 It has, however, been shown by Hermann Strecker,* and also by Godman and Salvin, f 

 that the name and description given by Linni^us really apphed to a well-known and widely 

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

 As it is im2)ossible 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 in my collection
