Papilio Ideoides. G. R. Gray, MLS. 
Uprrrsipr white. Both wings, with the costal and outer margins, the ner- 
vures (the median nervules broad), and a row of lunular spots parallel to the outer 
margin, black. Anterior wing, with the apex, broadly black. Some indistinct longi- 
tudinal lines in the cell, a broad band across its middle, another at its end (chiefly 
within it, inclosing an oblong white spot), and a large indistinct spot (chiefly between 
the second and third median nervules) black. Posterior wing, with a line placed 
longitudinally and a large spot at the end of the cell, black. The outer margin of 
both wings with white, lunular, or oblong spots. 
Unpersipe differs only in having a small black spot at the anal angle of the 
posterior wing.

This is one of the most remarkable amongst the many contrasting forms and varied modes of 
colour, which mark the genus Papilio. It would scarcely be known at first sight from an Idea. 
Papilio Hippocoon, and Danais Niavius, are sometimes put together in collections as the same species. 
Papilio Boisduvallianus, and the female of Acreea Iodutta, but for the difference of the nervures and 
antennee, do not differ more than closely-allied species of one genus. ‘Two or three Papilios represent 
very closely some of the Eupleeas, but it is remarkable that this close approximation in appearance 
is chiefly seen between Papilio and the Danaide, and though it occurs also between Papilio and 
Acreea, and to a certain extent in the likeness between P. Zagreus and Heliconia (neighbouring families 
to the Danaidee), it is not seen in the Nymphalide, or other groups.
