A, celeriont quoque similis, sed fascia communi forsan angustiore et pure alba, macula fulva infra plagam 
fulvam notata; subtus alis omnino magis distincte picturatis et lunulis submarginalibus, precipue eis 
anticarum, distinctioribus.

plain of Salama (Hague), central valleys (F. D. G. & O. S.); Costa Rica, Rio Sucio 
(Logers). 
Mr. Bates, in describing this species, compared it with A. serpa, from which it differs 
in the white band being entire from one end to the other. Beneath the general colour 
is whiter, the outer border of the white band is much darker in colour, the double row 
of submarginal lunules is more pronounced, besides minor differences. 
We have little doubt that the species described by Rudolph Felder under the 
name of fH. emathia, from Potrero in Mexico, belongs to this species. Not only do 
Mexican specimens from the same district agree with our Guatemalan type, but notes 
we took on this species, when in Vienna some few years ago, confirm us in this view. 
In Guatemala A. parewca is by no means a common species; our type, and all the 
specimens we have since received were taken in the neighbourhood of San Gerdénimo 
in Vera Paz. <A single specimen from Costa Rica does not differ materially from more 
northern specimens.

Limenitis eulalia, Doubl. & Hew. Gen. Diurn. Lep. t. 36. f. 1’. 
Alis fuscis, cellula anticarum maculis duabus indistinctis transversis nigro utrinque marginatis, linea altera 
nigra inter eas; plaga magna subtriangulari subapicali fulva; fascia communi a costa anticarum fere ad 
angulum posticarum analem alba, in anticis in maculis disjuncta; subtus parte proximali fulvida lineis 
griseis nigro marginatis variegatis; parte distali lete brunnea, lunulis submarginalibus serie duplici 
positis albidis, posticis fascia alba utrinque nigro limbata et fascia altera angusta extra eam grisea notata.

(Hague), Santa Rosa in Vera Paz (Champion). 
Californian examples of a species allied to this Butterfly have been separated by 
Mr. Butler under the name of Heterochroa californica, several small differences serving 
to distinguish them. The true A. bredowi, however, occurs in Arizona, as Mr. 
Morrison’s specimens recently sent from there prove to belong to the southern rather 
than to the northern form. 
A. bredowt is a local species sparingly distributed in Mexico and only found in
