43G ERYCINID.E. 



Genus XVII. CALYDNA. 



Caltdna E. Dovbledm/, List Lep. B. M. 

 Tharops, J^^theius, and Hamanumida p. Uiibner. 



Body rather slender : wings large, irregular along the apical margins; dark-coloured, and marked M'ith numerous 



freckles and small spots of various colours. 

 Head modei'ate-sized, slightly tufted in front below the antennce. 



Eyes naked. 



A7itenncc o^ moderate length, slender ; articulations ringed with white, those next the base of the club almost 

 entirely white. Club elongate, gradually formed, about twice the thickness of the I'est of the antenna, obtuse 

 at the tip. 



Labial Palpi very small, hairy beneath. Basal joint curved, nearlj' as long as the middle one, which is straight 

 and nearly horizontal ; terminal joint minute, slender, nearly naked, the tip not extending beyond the hairs 

 of the face. 

 Thorax rather broad, clothed with hairy scales at the sides and behind. 



Fore Wiiigs somewhat triangular. Costal margin nearly straight ; apex subobtuse. Apical margin about five 

 sevenths of the length of tlie costal, irregularly waved. Inner margin nearly straight, about the length of the 

 apical. Postcostal vein with three brandies : the first and second arising close together before the anterior 

 extremity of the discoidal cell ; third branch arising about half way between its extremity and the tip of the 

 wing. Upper disco-cellular vein obsolete : middle one arising simultaneously with the upper discoidal (which 

 follows the direction, and might be regarded as the extremity, of the postcostal vein) at about the length of half 

 the wing, very slender, transverse : lower disco-cellular also very slender, rather longer, following the same 

 direction, and closing the discoidal cell transversely at about the middle of the wing, by its union with the third 

 branch of the median vein close to. or at a very short distance beyond, its origin : the space between the second 

 and third branches of the median vein, and that between its first branch and the submedian, forming deeper 

 scallops than between any of the other veins. 



Hind Wimjs subovate, angulated near the base of the costal margin, irregularly scalloped along the outer margin ; 

 the anal margin scarcely forming a channel for the reception of the abdomen. Costal vein extending to the 

 outer angle of the wing. Postcostal vein branching at a rather short distance from the base. Upper and lower 

 disco-cellular veins very slender ; the former arising quite close to the origin of the branch of the postcostal, and 

 the latter joining the median quite close to the origin of its third branch. 



Fore Legs of the male very small, and densely hairy. Fore Legs of the female twice the length of those of the 

 male, very slender, scaly. Femur about one third longer than the tibia. Tibia and tarsus of equal length. 



Four Hind Legs slender, long, scaly. Femur slightly hairy beneath. Tibial spurs very minute. Basal joint 

 of the tarsus considerably elongated ; all the joints armed beneath at the tips with a pair of minute spines. 

 Claws and their appendages very small. 



The clark colours of the wings of the butterflies of this genus, niai-ked with numerous small dots and spots of various tints, giving 

 them a freckled appearance, Tinitcd with the irregular apical margin oF the wings and the antenna? ringed with white, will serve to separate 

 the species from the adjoining groups. The si)ecics appear ratlicr numerous ; some of them liaving the wings not so irregularly scalloped 

 as in the type, and the spots larger, paler, and more regularly arranged. Pa|iilio Meris, which Mr. E. Doubleday introduces into the 

 genus in the List of the Lepiihipteroiis Insects of the British Musntm, does not associate well with the rest, having differently shaped 

 wings, with a very different style of marking, and also possessing hairy eyes.
