H. cyrbia, Godt. 



The typical and two subspecies are described from 

 Ecuador, Colombia, and Bolivia. 



H. favorinus, HopfL 



A Peruvian form. 



H. petiveranus, Doubl. 



The typical and one subspecies described from Colombia, 

 Venezuela, and Central America. 



H. hydarus, Hew. 



Five subspecies are described. The forms occur in 

 Venezuela, Trinidad, Colombia, and Panama. The forms 

 are remarkable for the great diversity of colour and pattern 

 exhibited. 



H. amphitrite, Riff. 



A Peruvian species closely resembling erato callycopsis 

 viculata. 



H. erato, Linn. 



The typical and no less than eleven subspecies are 

 described. Extending over the greater part of northern 

 S. America. It is a species in which pattern and colour 

 seem to run riot much as in melpomene. 



Claspers taken from the foregoing eight reputed species 

 are illustrated on PI. XVII. All are characterised by 

 the toothed projection at the outer end of the clasper, 

 which takes the form of a flattened lobe with a peculiar 

 twist, as though it had been taken in forceps and given 

 part of a turn, whilst the rest of the clasper remained 

 fixed. An examination of the figures shows that no 

 satisfactory character differentiates these forms. The 

 figures are only a selection from many preparations, all 

 of which show the same kind of structure. Whether or 

 not all are forms of one species, they certainly cannot 

 constantly be distinguished by the structure of the 

 armature. 



One more species of the group remains, viz. — 



H. hermathena, Hew. 



This remarkable species from the Lower Amazon region 

 has the fore-wings of one of the erato forms and the hind-
