52 [August, 
In the " Proceedings of the Zoological Society" for 1863 (p. 245, 
pi. xxix., f. 5), I described a local form of /. Iphianassa brought home 
by Messrs. Godman and Salvin from Panama. I have since found that 
this form, /. IjjJnanassa, var. panamensis, agrees very closely with 
Fabricius' description of his Heliconia Lycaste in Entom. Systematica 
III. I. 161, 497. Mr. Tryon Eeakirt, of Philadelphia, has received this 
species from Kansas, much beyond the northern tropic* 
91. — Ithomia adelphina. 
I. VIEGI^^IANA, Hewits. Exot. Butt. Ithomia, f. 112 (?). 
This species is closely allied to I. virginiana, Hewits. loc cit. f. 54, 
and it is probable the same as represented in fig. 112 of the same work. 
Its chief difference from I. virginiana consists in the dark parts of the 
under-surface being of a deep black hue, including the outer border of 
the hind-wings ; these parts in the true I. virginiana being of a muddy- 
tawny hue. There is also a difference in the extent of the orange- 
tawny spot of the upper-side of the fore-wing, which in Ith. virginiana 
extends as far as, or beyond, the second median branch, and in I. 
adelphina does not reach the first median branch. 
I. virginiana inhabits Mexico and Guatemala ; Ith. adelphina the 
Isthmus of Panama and New Granada ; they may therefore Be con- 
sidered local fornis of one and the same stock ; the differences, however, 
are constant and well-marked, and the two forms must be designated by 
separate names. 
92. — Ithomia (Oleria) xanthina. 
^ . Exp. 1" 10.'" Allied to I. Gazoria, Godt., audi. Zemira, Hewits- 
Wings blackish ; fore-wing with an elongate triangular basal spot, and 
an oblong sub-apical one yellowish-hyaline, the former sulphur-yellow 
and sub-opaque in the middle. Hind-wing with a broad discal stripe 
of the same colour (also opaque and sulphur-yellow in the middle), 
extending to the abdominal edge. The broad outer borders have a row 
of white spots in both wings. Beneath : the same. Antennae black ; 
collar and wing-lappets reddish. 
Panama. 
(To he continued.) 
* An interesting form of the group to which /. hernldica and I. Iphianasea belong is the following, 
which I alluded to in the Proceedings Zool. Soc. loc. cif. as a local form of /. Iphianassa. Its differ- 
ences are too well marked to allow of its being considered as merely a local form of that species. 
Jth. Spruceana. Similar to the var. of /. Iphianassa figured in Hewits. Exot. Butt. Ith. f. 92, 
difl'ers, however, in having a distinct upper disco-cellular nervule in the fore-wings (cj & 9), '" the cell 
s))nt of the fore-wing being prolonged towards the base, and in the hind-wings being fres from all trace 
of black spot at the end of the cell. The colours are neiirly the same, but the black border of the fore- 
wings i'f KHarcily widened at the ajiex. Western foot of Chiinliorazo, alt. 3 — 4,000 feet. Sent home in 
considerable numbers by Dr. Spruce.
