66 Mr. W. C. Hewitson on 
five indistinct subapical spots. Posterior wing crossed 
obliquely by four bands of paler colour, converging to- 
wards the anal angle, the fourth band submarginal. 
Underside: rufous, clouded with brown towards the 
outer margins of both wings. Anterior wing with a bifid 
spot at the base, an oblong spot bordered with black in 
the middle of the cell, aud four small spots below these, 
all silvery-white ; the band of the upperside and five 
subapical spots white. Posterior wing crossed before the 
middle by two parallel bands of silvery-white, the band 
nearest the base broken in the middle; crossed at the 
middle by a band of black, and beyond the middle by a 
submarginal band of seven silvery-white spots. 
Exp. 2,1, inches. 
Hab.—New Granada. In the collection of W. W. 
Saunders and W. C. Hewitson. 
Nearly allied to I. Hpione, which, instead of having the 
transverse white bands of equal breadth, parallel to each 
other, and slightly curved towards the base as in this 
species, has the second band very broad, and with its 
outer border curved towards the outer margin of the 
wing. 
Hurygona argentea. 
Male. Upperside: dark brown. Anterior wing rufous 
below the median nervure, from the base towards the 
middle of the wing, where it ends in a more distinct 
round spot. Posterior wing with a longitudinal rufous 
band from the base to the outer margin. 
Underside: silvery-white. Anterior wing with four 
transverse bands, and the outer margin, dark brown. 
Posterior wing crossed by six brown bands, all tending 
towards the anal angle: two from the base, a third from 
the costal margin united to the fourth, which runs near 
the inner margin, the other two submarginal, the outer 
one marked by a small black spot; the outer margin 
black, marked by a large orange spot. 
Exp. 1 in. 
Hab.—Nicaragua (Chontales). In the collection of 
Thomas Belt. 
Unlike any other species, and one of the most beautiful.
