group, and is most nearly allied te L. abdida (Hew.), from which it differs in the absence 
of a black band on the secondaries. 
6. Leucothyris pagasa. (Jthomia pagasa, Tab. III. fig. 15.) 
Ithomia pagasa, Druce, Ent. M. Mag. xii. p. 126°. 
Alis obscure nigris, macula intra cellulam elongata ad basin extendente, altera subovata a costa per cellulam 
ad angulum analem ducta, altera extra eam minore et tribus submarginalibus flavo-hyalinis ; posticis 
medialiter eodem colore notatis: subtus sicut supra, margine externo nigro punctis albis ornato.

The nearest ally of this species is L. zelica (Hew.), from Western Ecuador; but it 
has many points of distinction. The yellow spots of the primaries are darker in tint 
and more distinct in outline; and the base of these wings is nearly black instead of the 
costa and inner margin alone being of that colour. 
LL. pagasa appears to be a rare species, but few specimens having come under our 
notice: of these, two were obtained by Mr. Rogers during his late expedition to Costa 
Rica; the rest, including Mr. Druce’s type, all came from the neighbourhood of 
Veraguas, in the State of Panama. 
7. Leucothyris makrena. 
Ithomia makrena, Hew. Ex. Butt. Ith. t. v. f. 29°. 
Alis pellucidis, venis et marginibus, his intus valde sinuatis, fusco-nigris ; cellula anticarum macula fusco-nigra 
trigona bisecta, macula altera ad finem subquadrata: subtus sicut supra, sed maculis omnibus obscuris 
rufescentioribus et limbo marginali maculis subobsoletis albis ornato.

This common Colombian species is only known to us as an inhabitant of Central 
America from a single specimen supplied to us by Herr Ribbe, who obtained it during 
his stay on the Panama railway-line. This specimen (a male) exactly resembles the 
typical form found in Colombia, from which Ecuadorian examples differ to some 
extent in the greater breadth of the marks of the primaries, and especially the margin 
of the secondaries. 
EPISCADA (gen. nov.). 
Costa of secondaries of male gradually curved; lower discocellular at right angles 
to third median segment and bent to a right angle where it emits the recurrent 
nervule ; middle discocellular nearly in a line with upper segment of lower disco- 
cellular; upper discocellular short, directed outwards; upper radial twice as long as 
the distal segment of the subcostal; subcostal strong; proximal segment slightly
