CALLOLERIA.—HYPOSCADA. 35 
2. Calloleria azara. 
Ithomia azara, Hew. Ex. Butt. Ith. t. iv. f. 23°; Equat. Lep. p. 13?. 
Ithomia dorilla, Bates, Ent. M. Mag. i. p. 35°, iti. p. 157%. 
C. tutie similis, sed alarum coloribus saturatioribus, macula pellucida apicis anticarum absente ; posticarum 
linea longitudinali mediana fere obsoleta. 
Hab. Panama, Calobre (Arcé), Lion Hill (‘Leannan’).—Ecvavor ! ?. 
Panama specimens of this species were described by Mr. Bates as distinct from the 
Ecuadorian C. azara?; but an examination of a larger series of examples subsequently 
showed him that the two were not really separable*. The insect is common on the 
Isthmus of Panama, where, as we have already said, it appears to supplant C. tutia— 
the two forms mingling in Costa Rica, where the true C. azara does not occur, so far 
as we know. In the southern continent this species is less common; but Mr. Buckley 
obtained specimens of it during his first journey to Ecuador’. 
HYPOSCADA (gen. nov.). 
Antenne long; costa of secondaries of male curved rather abruptly near the apex ; 
lower discocellular bent to an acute angle where recurrent nervule is emitted; lower 
segment curved; upper segment straight, about half the length of the middle disco- 
cellular ; upper discocellular directed outwards about half the length of the middle 
discocellular ; proximal segment of the subcostal not much longer than the distal 
segment, and about equal to the three segments of the median nervure ; cell conse- 
quently short; costal and subcostal nervures wide apart and but slightly curved at 
their distal ends. Tarsus of front leg of female with five joints, with a pair of spurs on 
each of the second and third joints. (Type Jthomia adelphina, Bates.) 
The shortness of the cell of the secondaries in the male of this butterfly, coupled 
with the wide separation of the costal and subcostal nervures and the length of the 
antenne, seems to justify its removal from the old genus [thomia. 
Only two closely allied species are found in Central America; but in South 
America several more occur. These show considerable diversity of coloration, but in 
the main the same wing-structure. 
1. Hyposcada virginiana. 
Ithomia virginia, Hew. Ex. Butt. Ith. t. ix. f. 54° (nec t. i. f. 18). 
Ithomia virginiana, Hew. Ex. Butt. Ith. t. xviil. f. 111, text*; Bates, Ent. M. Mag. iil. p. 52”. 
H. adelphine similis, sed supra obscuriore ; area anticarum ferruginea ramum medianum secundum tenus (nisi 
margine interno) extendente, maculis albis vix flavescenti tinctis: alis subtus quoque dilutioribus colore 
paging superioris nigro ferrugineo multo intermixto.
