Pupae thought to belong to the butterflies Heliconius burneyi, H. tales, H. aoede, H. xanthocles and H. clysonymus are briefly described.

Division of the genus according to morphology, especially of the pupae, shows that the Mullerian mimicry shown by some species, for instance, the “red-and-yellow”H. melpomene, H. erato, H. burneyi and H. aoede and the “blue-and-yellow”H. wallacei and H. sara, results not simply from failure to diverge but from convergent evolution of the patterns. There is some evidence that the larvae have evolved Mullerian mimicry.

The pupa of H. doris is dimorphic for a striking morphological character—the presence
