(ab.) perintniea Prout. ab. nov.* (Rio Madeira). 

 Distributed from Central America to Bolivia and Argentina.

 — aurata Warr., Nov. Zcol. xii. 312 (1905) (Campylona) (Bogota). 



Also known from the Peruvian Amazons. Possibly a recurrent aberration 

 of the preceding.

Unknown to me in nature. 



Sect. II. — Palpus not over twice diameter of eye ; forewLng with DC long, 

 DC deeply inangled, R= from close to R' (Neolaurona). 



1. hazara Butl., Ann. Mag. Nat. Hist. (4) viii. 287 (1871) (Pericopis) (Brazil). 



Seems confined to the Amazons, Ecuador, and Peru. Mimetic of Stalachtis 

 calliope L. Rather variable, the horse-shoe shaped black mark in the male 

 (only) often filled in more or less completely with black, forming a nearly circular 

 patch. A form from Pachitea, Peru, with the subapical band of the forewing 

 wanting — the entire ajsical area being black — and the black markings on the 

 hindwing reduced, was labelled by Druce hdiconides and regarded by him as a 

 distinct species. His " type " and another ? conform to the above description, 

 but the third example (also 5) from the locality combines the fore\^ing of 

 typical hazara with the hindwing of heliconides. If Druce's name is hitherto 

 " ined." — I can find no reference — the authorship may be attributed to me : 

 Fhaeoclilaena hazara $ — f. heliconides, form. nov. ; tj^pe in coll. Joicey. 



Sect. III. — Palpus over twice diameter of eye ; both wings with DC 

 straightish,R= of forewing little, of hindwing scarcely, before midd\e(Cla{tognatha) .
