PERISAMA. 241 



rounded at the apex, rather shorter than the tibia. Anterior Legs of the female rather slender, 

 clothed with scales and, thinly, with long hairs. Femur subcylindric, rather longer than the 

 tibia. Tibia nearly cylindrie, slightly curved, the base rounded, the apex truncate, armed with 

 two or three slender spines. Tarsus about three fourths the length of the tibia : all the joints, 

 except the fifth, spiny laterally, the spine on each side of the apex longest. First joint equal in 

 length to the rest combined ; second, third, and fourth progressively shorter, the last about 

 equal in length and breadth ; fifth joint about as long as the fourth, acuminate or rather 

 mucronate, its side furnished with a tuft of seta?. 

 Middle and Posterior Legs moderately stout. Femora somewhat swollen in the middle, those 

 of the middle pair longer than those of the posterior pair, equal in length to the tibia?. 

 Tibia? nearly cylindrie, spiny, the spines on those of the middle pair placed in two tolerably 

 regular interno-lateral series, and, in addition, some few scattered spines ; those of the posterior 

 pair less numerous, irregular, more numerous towards the apex, where they form two tolerably 

 regular series. Spurs stout. Tarsi becoming gradually slenderer from the base to the claw ; 

 all the joints, except the fifth, spiny laterally and below ; the spines below arranged somewhat 

 in two series, especially on the first joint. First joint not quite equal to the rest combined ; 

 second, third, and fourth progressively shorter, the fourth being nearly three fourths the length 

 of the second ; fifth equal in length to the second and third combined, produced at the apex 

 above, having only three or four slender spines on each side. Claws curved, grooved below. 

 Outer lacinia of the paronychia slender, except at the base, strap-shaped, as long as the claw. 

 Inner lacinia shorter, triangular. Pulvillus jointed, not so long as the claws. 

 Abdomen moderately stout, about two thirds the length of the inner margin of the posterior wings. 



Larva and Pupa unknown. 



It is only after careful examination that I have resolved to divide this genus from Catagramma, which genus it 

 resembles in the neuration of the wings, and very nearly in the structure of the antennas and palpi. With these 

 characters it has, however, the hairy eyes and the more slender anterior feet of Callicore, and differs in other 

 characters from both the above-named genera. 



The species composing it are rather more robust than those of the preceding genus, and, in one or two instances, of 

 rather larger size. Above, all the wings are black, with a green transverse band, and sometimes a vitta of the same 

 colour extending from the base of the wing nearly to the middle of the disc. Below, the anterior wings sometimes 

 have the base crimson, as in Callicore ; sometimes black, marked with brilliant blue spots. The posterior wings have 

 none of the circular or oval markings which distinguish the preceding and following genus. They are generally grey, 

 or of some shade of brown, tending sometimes to red, sometimes to ochrey yellow, and are crossed by two slender lines, 

 between which is often a series of black dots. One insect, which I have placed with doubt in the genus, has the 

 upper surface black, with brilliant blue reflexions ; the lower surface of the posterior wings of a yellowish brown, 

 curiously marked with whitish spots. 



These insects appear to be confined to the eastern slopes of the Andes, where the westernmost tributaries of the 

 Amazon have their sources, and to the mountain ranges of New Granada and Venezuela. All the species are rather 

 rare in collections.
