ITHOMIA. 49 
Mr. Reakirt, in a careful examination of the races of Ithomia iphianassa and its 
allies? 4, identified specimens he had received from Los Angeles, California, with the 
Papilio lycaste of Fabricius*, from which Panama specimens hardly differ, if they do at 
all. Whether the name P. lycaste is really applicable to this insect is, we think, open to 
question. Mr. Butler, who had access to Jones’s unpublished drawings, when compiling 
his ‘Catalogue of Fabrician Rhopalocera,’ applied the name to a specimen of Calli- 
thomia in the British Museum, which may have been Fabricius’s type, who described 
an insect in Drury’s collection. Many of Drury’s specimens were purchased by Milne 
when this collection was sold by auction; and it was from Milne that the Callithomia 
in question was acquired by the British Museum. As the question cannot now be 
settled satisfactorily, we think it best to use the name I. panamensis, upon which no 
doubts rest. Los Angeles in California is a very long way from the usual range of 
this species; and it seems possible that some error has been made in the locality 
attributed to the specimens received from there by Mr. Reakirt. So far as our know- 
ledge of the insect goes, its range is restricted to the Colombian States of Panama and 
Antioquia.

Alis anticis fusco-nigris, fascia plerumque semihyalina et rufo marginata a basi prope angulum analem exten- 
dente, macula obliqua subquadrata cellulam transeunte, altera elongata infra eam inter ramos medianos 
secundum et tertium, una subapicali tripartita punctisque apicalibus quatuor flavis ; posticis fulvis interne 
semipellucidis, margine externo fusco indistincte punctulato : subtus ut supra, sed anticis punctis apicalibus 
albidis, posticarum margine septem punctis albis notato, coste basi et corpore infra sulphureo tinctis ; 
antennis basi nigris, apice flavis.

cisco, Caché (Rogers); Panama, Veraguas (Arcé). 
A species allied to I. iphianassa, but quite distinct from any of the forms of that 
insect. It was first described from specimens from Costa Rica, where it would appear 
to be common. It is equally common in Nicaragua, having been obtained by all 
collectors who have worked in the mining-district of Chontales. We have only a 
single specimen from the State of Panama; we therefore conclude that it hardly passes 
beyond the limits of Costa Rica in that direction.
