MORPHID^. 



disco-cellular equally short, nearly transverse ; outer disco-cellular very long and curved, somewhat like the 

 letter ri , the extremity reaching nearly to the middle of the wing, where it joins the tliird branch of the 

 median vein at a short distance beyond its base, terminating the closed discoidal cell nearly in a point. 



Hind Wings broadly ovate. Fore margin scarcely curved. Outer margin rounded; anal angle rounded. The 

 disc above, near the extremity of the thorax, is furnished with a tuft of fine hairs in the male. Precostal vein 

 short, curved towards the body. Costal vein extending to about two thirds of the length of the costa. Post- 

 costal vein with its branches arising quite close to the base of the wing, the outer branch extending to the 

 outer ano-le. Discoidal cell very narrow and open. Median vein with its branches wide apart. 



Fore Legs of the male very small and brush-like, very woolly. Fore Legs of the female longer than those of the 

 male, slender, scaly. Tarsus not half the length of the tibia ; articulations indistinct, except when denuded of 

 scales ■, obliquely truncate at the tip ; armed with very small spines. 



Four ITind Legs long, strong, scarcely spined beneath. Tibial spurs minute. 

 Abdomen rnther small and slender. 



Transfoiimations unknown. 



This is a genus of very plain-looking butterflies, which have been united by Hiibner and Godart with the Satyridae, but which are 

 certainly most nearly allied to Thaumantis, from which they are at once distinguished by the second, tliird, and fourth branches of the 

 postcostal vein of the fore wings arising very close together, far beyond tlie extremity of the discoidal cell, and by the row of small 

 spots on the under side between the middle and outer margin. In the typical species, C. Eumeus and Arcesilaus, are slight indications 

 of several dusky strig* running across all the wings, visible especially in the hind wings. 



The very remarkable butterfly figured in our Plate LIV., under tlie name of Thaumantis Faunula, ought also to be refen-ed to the 

 present genus, agreeing therewith in the arrangement of the veins of the wings, and also in their tasciated under surface; since, being 

 semi-transparent, the undulating fascia; and spots seen in our figure are those of the under side, which is far more striking in its 

 .nppearance than the upper, being white, with the markings quite black; there being also one near the apical margin of the fore 

 wings corresponding with that of the hind wings, represented in our figure. 



All these insects are natives of India and the Indian islands.
