of the hind-wings angulated below, and with a strong project- 

 ing tooth at the outer angle. Now, however, they are con- 

 sidered to be nearly allied to Argynnis, but their shape, com- 

 bined with the two large eyes on the hind-wings, will be amply 

 sufficient to distinguish them from any other genus of this 

 group. They are large insects, four or five inches in expanse, 

 and are peculiar to India and the Indian and Austro-Malayan 

 islands as far as New Guinea. The sexes are very dissimilar, the 

 males being orange-tawny or fulvous, and the females brown, 

 with blue and white markings. They still require careful study 

 in order to determine the number and range of the species, 

 and to assign the sexes correctly. As in many other Butterflies, 

 the females are much larger than the males. 



CYNTHIA JULIANA. 

 (Plate XIX., Fig. I.)

 (1780). 



This fine Butterfly is a native of the Island of Amboina, and 

 measures nearly five inches across the wings. It is generally 

 regarded as the female of C. arsinoe (Cramer), a fulvous Butter- 

 fly, with two large eyes on the hind-wings ; but as this is un- 

 certain, it is better to employ the name given by Cramer to the 

 present insect, though there is little doubt that the true male 

 will ultimately prove to much resemble C. arsinoe. 



In C. Juliana the wings are brown above, and the fore-wings 

 are bordered with pale blue, followed by two black lines, one 

 marginal, and the other sub-marginal. Within these are three 

 irregular rows of white spots and crescents, generally bordered 

 with black. In the cell are two blackish transverse streaks. 

 The hind-wings are marked with a very broad sub-marginal 

 bluish band, with an irregular border on the inner side, and 

 are bordered on the outside with large black and bluish-white
