ITHOMIA XXVIII. 
PTHEOMEA ALPHESIB@A. 178. ¢ 
Ithomia Alphesibea, Hewitson. Equatorial Lepidoptera, p. 17, 1869. 
Uprersipe. Male, transparent. Anterior wing tinted with lilac from the base tothe middle, 
rufous beyond it, with the costal margin, the inner margin, the nervures, and triangular spots on 
the outer margin at the end of the nervures, brown: the costal margin from the middle to the apex 
rufous-orange. Posterior wing lilac-white, the outer margin broadly rufous: the costal margin, a 
spot at the apex, and a triangular spot on the second median nervule red-brown. 
Unpersibz as above, except that the costal margin of the posterior wing is broadly rufous, paler 
at its base. ys 
Exp. 24% inch. Hab. Ecuador. (Mapoto, Buckley.) 
This species is altogether so much like 7. Duillia that, but for its great inferiority in size, I should have passed 
it as the same. On the anterior wing of J. Duillia the point or spur is emitted at the end of the cell from the 
second disco-cellular nervure, in J, Alphesibea from the third, and what is very remarkable, because it occurs in the 
females only, the discoidal nervure 178a of the posterior wing of Alphesibea emits a branch, whilst in Duillia 178b a 
‘similar branch is emitted from the subcostal nervure. 
ITHOMIA EPONA. 179. 
Ithomia Epona, Hewitson. Equat. Lep. p. 19, 1869. 
Urprrsipr. Male, transparent rufous-white: the nervures black. Anterior wing with 
the costal margin and apex rufous: the inner margin broadly dark brown rufous at the base: a 
triangular spot im the cell, a curved narrow band at the end of the cell, and spots on the outer margim, 
all black. Posterior wing with the outer margin brown. 
Unpers1bzE as above, except that the margins are rufous, that there are three white spots on 
the apex of the anterior wing, and a series of similar spots on the outer margin of the posterior 
wing; that the base of the posterior wing is pale yellow bordered below with black, and marked by 
the singular oval white spot which indicates the sex. 
Exp. 24 inch. Hab. Ecuador. (St. Ines, Buckley.)

ITHOMIA TICIDA. 180. 
Ithomia Ticida, Hewitson. Equat. Lep. p. 21, 1869. 
Uprrrsipr. Male, transparent rufous-white: the base of both wings tinted with orange: 
the nervures black, slender: the margins dark brown. Anterior wing with the usual costal spot 
obscure white. 
UnpersIbDE as above, except that the costal margin near the apex of the anterior wing is rufous, 
that there are three subapical snow-white spots, and that the posterior wing has the base yellow, and 
a submarginal series of five white spots.

Upprrstpr. Female, transparent white: the nervures black. Anterior wing with the costal 
margin, a triangular curved spot at the end of the cell, the apex (which is broad), and the outer and 
inner margins, all black. A small white spot on the costal margin at the end of the cell. Posterior 
wing with the costal and outer margins black. 
Unperstpb as above, except that the margins and band of the anterior wing are all rufous, and 
that each wing has two apical white spots.
