first, third three-fourths the length of the second, fourth rather more 

 than half the length of the third, fifth not quite so long as the third. 

 Claws curved, acute, grooved below; paronychia bilaciniate ; the 

 outer lacinia slender, pointed, not so long as the claw ; the inner 

 lancet-shaped, much broader than and nearly as long as the outer, 

 very hairy ; pulvillus jointed, broad, not so long as the claws. " Ab- 

 domen rather short, not robust. 



This interesting genus, as remarked above, appears to be almost 

 confined to the eastern slopes of the Andes and to the great branch 

 of that mountain-range which runs along the northern parts of South 

 America. Nearly all the specimens of the five or six species belong- 

 ing to it existing in British collections were sent home by Mr. Bridges 

 from the eastern parts of Bolivia, and by Mr. Dyson from Caraccas. 

 The peculiar sexual scales on the disc of the anterior wings of the 

 males resemble those of the males of most species of this family in 

 being long, tapering to a delicate hair-like point, at the end of 

 which is a little plumelet. 



In form this genus resembles the P. Actorion of Linnaeus, which 

 is the type of the genus Napho of Boisduval, but that insect belongs 

 to the preceding family of Morphidce.

Anterior wings, above chocolate-brown at the base, darker at the 

 apex and along the outer margin ; between the cell and the apex is 

 a transverse band composed of three fulvous spots, the first of which 

 is divided by the subcostal nervure ; midway between the cell and the 

 outer margin a curved spot of the same colour, divided by the first 

 median nervu-le, and a rounded spot of the same colour near the anal 

 angle. Posterior wings with the anal angle considerably produced 

 into a tail, entirely chocolate-brown. Below, the anterior wings are 

 fuscous, the base rather paler, the apex ashy ; the subapical spots 

 nearly white, the others as above ; the posterior wings clouded and 

 freckled with ashy-grey and fuscous, having a slight silvery reflec- 

 tion ; a transverse band, commencing on the costa, crosses the middle 

 of the cell, and terminates before it reaches the inner margin ; a 

 second similar band commences on the costa, and running along the 

 lower disco-cellular nervule, terminates at the tail. 



Head, thorax and abdomen fuscous above, the two latter greyish 

 below ; antennae fuscous ; palpi fuscous above, pale below. 



This insect was taken by Mr. Dyson in the mountains of Caraccas, 

 where it seems to be rather rare.
