boundary of thorax and abdomen ; subsequently, however, it turns to a light 

 rose and the white of the band changes into a row of golden dots or pearls. 

 Whether the surroundings during pupating are light or dark exercises no 

 influence upon the colour of the pupa. The caudal hook is black and close to 

 it four black spots are to be observed. A chrysalis of 2 1 F'ebruary produced 

 the imago on March i while from pupae of 23 February the perfect insects 

 emerged on March 2 and 3. The description given of the larva of this species by 

 Moore does not agree with mine and has reference to a caterpillar with 3 pairs 

 of processes, like that of D. Melanippus Cram. The same applies to the figure 

 given by Horsfield, also based on a specimen from British India and this 

 fact makes it appear probable that the Javanese Genutia is not identical with 

 that from British India.

The specimens from Java belong to the dark form BArAviAN.\ Moore ; the 

 shade of the principal colour varies, however, some 6 especially being con- 

 siderably lighter in hue, although not so light as the typical form which occurs 

 elsewhere. The process of fading to yellow and white in this species generally 

 manifests itself strongly over its very extensive range and thus produces all 

 manner of so-called varieties, which, however, have partly been obtained also 

 by breeding from tj'pical parents. Thus, for instance, the forms Alcippus and 

 Alcippoidhs, which do not occur in Java, have been distinguished. The form 

 Petilia Stoll, from the east of the Archipelago and North Australia, is also of
