CALLIZONA. 247 



short spur on each side ; third joint not quite two thirds the length of the second ; fourth joint 

 very short, but much longer below than above, the apex with a long spine on each side 

 projecting beyond the fifth joint ; fifth joint short, transverse, broader below than above, the 

 sides furnished with a tuft of seta3. 

 Middle and Posterior Legs rather slender ; the femora of the former longer than the tibiae, those of the 

 latter equal to them in length. Tibirc irregularly spiny within and externally ; the inner spines 

 tending to form two interno-lateral series towards the apex, the outer spines few and wide apart ; 

 spur moderately long. Tarsi nearly as long as the tibia? ; all the joints spiny laterally below, the 

 spines arranged in four series except at the base of the first joint where they are wanting on 

 one side at the base, and on the fifth joint where the lateral rows are wanting. Claws rather 

 slender, curved, grooved below. Outer lacinia of the paronychia as long as the claw, narrow, 

 strap-shaped ; inner lacinia broad, nearly triangular, shorter than the outer. Pulvillus with 

 the second joint broad, nearly as long as the claw. 

 Abdomen slender, about three fourths as long as the inner margin of the posterior wings. 



Larva cylindric, spiny, the head having two long spines on the crown, and two shorter ones 



on each side ; each segment, except the prothoracic, having several verticillate spines. 

 Pupa gibbous, spiny ; the head armed with two long curved processes. 



Though Callizona has strong affinities to the neighbouring genera, it somewhat interrupts their natural order of 

 succession. Perhaps, when we know the metamorphosis, it may be found advisable to change the position of the last 

 two genera, and place them nearer to Apatura and the allied genera, in which ease this genus would make an easier 

 transition from Callicore to Gynascia. Godart has placed the only species belonging to it in his genus Argynnis, and 

 it must be confessed there are some presumptions in favour of such a situation : but its generic characters seem to me 

 to indicate a position near where I now place it. 



Callizona Acesta is remarkable for the beauty of the lower surface of its wings. The anterior wings have the base 

 and inner margin fulvous, shading off to pale straw-colour on the costa, and marked by four short brown bands; the 

 apical portion banded alternately with brown and pale straw-colour. The posterior wings are of a pale pearly grey 

 with violet reflections, and are crossed by numerous brown bands; and near the outer margin by an irregular fulvous 

 band, bounded externally by a slender pale violet-coloured line, which is followed by three black clots connected by a 

 fine line of the same colour. 



The Larva, which, according to Stoll, feeds on the cocoa, is nearly cylindric, pale green ; except the head, the true 

 legs, and the anal prolegs, which are black. The head has two verticillate spines on the crown, and two simple ones 

 on each side. All the abdominal and the mesothoracic and metathoracic segments are furnished with verticillate black 

 spines. 



The Pupa is rather elongate, brown, with light green and silvery markings, hairy ; gibbous at the base of the 

 abdomen, where it has four black spines; the head has two long curved processes, notched at the sides. 



The specimen figured, which is from New Granada, has the transverse band of the anterior wings much wider than 

 in those from Guiana and Brazil. I do not think the difference is specific.
