These butterflies, formerly Graphium, are now divided into two genera Pathysa and Pazala. They are large white butterflies with black bars in the cells of the forewings, and the hindwings each bearing a long sword-like tail. They are butterflies of hilly forests from the Himalayas to the Northeast, except for the fivebar swordtail which also flies in the Western Ghats and the spot swordtail which is also found in peninsular India and the Indo-Gangetic plains.
