CYRESTIS.

thence to the anal angle the wing appears truncate, the anal angle itself being developed into a short, broad, 

 spatulated tail. Precostal vein forming a slender, curved, simple spur. Costal vein much curved along its 

 basal portion, then straight to the commencement of the emargination at the outer angle of the ■wing. Sub- 

 costal branched at about one fourth of the length of the wing from the base, emitting the upper disco-cellular 

 (close to the origin of its branch) which forms the base of the discoidal vein ; the lower disco-cellular arising at 

 the same distance from the base of the upper disco-cellular as exists between the base of the subcostal vein and 

 its branch ; lower disco-cellular straight, very thin, and united to the median vein at the base of its third branch. 



Fore Legs of the male very slender, short, and pectoral. The femur as long as the remainder of the limb, 

 curved outwardly about the middle, and clothed beneath with long silky hairs. Tibia very slender, scaly, 

 clothed within with short hairs, as is also the tarsus, which is not aljove the fifth of the length of the tibia, 

 very slender, simple, and exarticulate. Fore Legs of the female considerably longer than those of the male, 

 slender, and pectoral. Femur thickly clothed beneath with short silky hairs. Tibia slender, gradually 

 thickened towards the tip, finely scaly. Tarsus gradually thickened, short, with several pairs of minute spines 

 near the tip beneath, indicating the very short articulations, the three terminal ones being extremely short, 

 last joint without any claws or their appendages. 



Hind Legs moderately long and slender, scaly. Tibia with a few very minute spines, arranged wide apart in 

 two rows ; tibial spurs very short. Tarsi equal in length to the tibife, with several rows of minute spines on 

 the under surface ; basal joint about half the length of the tarsus ; terminal joint furnished with long setfe on 

 its upper side at the tip. Claws small, much curved. Paronychia bilaciniated, finely setose ; the outer lacinia 

 curved, broader, and obtuse ; the inner lacinia small, narrow, slender, and rather pointed. 

 Abdomen small, and slender, not above one third of the length of the hind wings.

The insects of this genus are amongst the most delicately formed and elegant species amongst the Nymphalidae ; the two species 

 represented in our Plate XXXII. being the most extreme in their forms, as well as e.xhibiting the general style of colours and marking of 

 these pretty insects, which, in addition to these circumstances, are distinguished by the elongated palpi, and tailed and lohed structure of 

 the hind wings. In this latter respect they approach Timetes ; but the insects of that genus have the tails longer, and are at once 

 distinguished by having the discoidal cell of all the wings open, the lower disco-ccllular vein being oljsolete. 



The typical species, C. Hylas, well figured by Clerek, has been confounded witli a distinct insect from Java, which is remarkable for 

 the difference of the ground colour of the wings in the two sexes, those of the males being orange, and those of the females white, 

 whence Zinken-Sommer was led to regard the sexes as distinct species. There is a remarkable monstrous specimen of this Javanese 

 species in the collection of the British Museum, having the subcostal and discoidal veins and the extremity of the left fore wing 

 abortive, so that the branches of the median vein are obliged to perform their office, and are accordingly bent forwards, the terminal 

 branch extending to the tip of the wing, which is oval at the extremity. In some of the smaller species, such as C. Risa E. Doubledai/, 

 and a small Javanese species for which I am indebted to Dr. Horsfield, to which I have apjilied the name of C. Rahria, the second 

 branch of the subcostal vein of the fore wings, instead of arising before the extremity of the discoidal cell, arises half way between its 

 extremity and the base of the third subcostal branch, agreeing iu this respect with Timetes. The lower disco-cellular vein of the fore 

 wings closing the discoidal cell is shown by the insects of this genus to be of inconstant value, being very well defined in C. Camillus, 

 extremely slender but apparent in C. Thyodamas, and quite obsolete in C. Recaranus. 



The greater number of the species of this genus are natives of India, the islands of the Indian Archipelago, and New Guinea ; 

 one very elegant species, C. elegans, has been described by Dr. Boisduval from Madagascar ; whilst C. Camillus, the largest species in 

 the genus, is a native of Tropical Western Africa.
