24 RHOPALOCERA. 
C. megalopoli simillima, sed fascia trigona flava alarum medium anticarum occupante angustiore et macula 
nigra inter ramos medianos primum et secundum interrupta; posticis omnino ut in C. megalopoli. 
Hab. Panama, Veraguas (Arce?), Lion Hill (I Leannan’). 
C. mylassa seems inseparable from this species, the difference apparently consisting 
of the reduction of the median yellow patch of the primaries into smaller spots than 
in C. cleis, and is thus a somewhat further departure from C. megalopolis than C. eles 
is. But as no two of Mr. Druce’s typical specimens are alike in this respect, and as 
the passage into C. cleis is almost perfect, C. mylassa cannot be distinguished with 
certainty. C. cleis is apparently by no means common in the State of Panama, where 
alone it has been found. Should it hereafter be found necessary to unite this species 
with C. megalopolis, as seems not improbable, the name the insect should bear is 
C. cleis. Its nearest ally is C. mergelena, Hew. 
Our figure represents the type, which came from Lion Hill. 
4. Ceratinia dionza. 
Ithomia dionea, Hew. Ex. Butt., /th. tab. v. f. 24°. 
Alis anticis fulvis, parte apicali, costs basi, margine interno et maculis duabus triangularibus (una intra 
cellulam, altera inter ramos medianos primum et secundum, hac apici nigro conjuncta) nigris ; fasciolis 
subapicalibus, una infra eas, et septem in margine externo seriatim positis sulphureo-flavis; posticis 
fulvis, stria transversa et margine externo nigris: subtus sicut supra sed alis pallidioribus et margine 
posticarum nigro punctis septem albis ornato. 
Hab. Guatemata, forests of Northern Vera Paz and Polochic valley (f. D. G. & 
O. S.).— Venezvetal. 
This species was described by Hewitson from specimens said to have come from 
Venezuela; but we have not yet met with it in collections from that country, whereas 
examples of C. fenestella occur in them not unfrequently. The only specimens we 
have seen are those obtained by ourselves in Guatemala, where, however, it cannot be 
said to be a common species. These agree very well with Hewitson’s figure. They 
show, however, some variation amongst themselves, in that the isolated spot between 
the first and second median branches of the primaries is in some specimens yellow (as 
in the typical figure), in others tawny. In C. fenestella this spot becomes part of the 
transverse yellow subapical band, and thus shows a somewhat different disposition of the 
yellow marks of this portion of the wing. The two races, however, are very closely allied. 
5, Ceratinia fenestella. 
Ithomia fenestella, Hew. Ex. Butt., Ith. tab. v. f. 25°. 
Ceratinia fenestella, Butl. & Druce, P. Z. 8. 1874, p. 334°. 
C. dionee simillima, sed alarum anticarum macula sulphurea inter ramos secundum et tertium margini externo 
propiore et fasciola transversa subapicali plerumque confluentibus, macula nigra inter ramos medianos 
primum et secundum subrotunda et apice nigro disjuncta.
