    7a & b.

    Probably Potanthus mingo.

    This belongs to a group in which the FW band spots 2 .# & 1b are relatively wide ,forming a compact band.

    They include P. ganda. & p.omaha, both with a yellow abdominal end.
    P. juno usually with spot 8 absent or vestigial.
    P. mingo is recognised from them by the black banded abdominal end & heavier UnH markings..

    Thank you a lot for your help. Now I know where and what to look for to id these difficult group of species, but still far from being confident. So, here are some more which I think are Potantus, requesting for your help.

    But before that, if you could tell how to differentiate between Potanthus, Telicota and Oriens. Maybe too basic, but because of pandemic, I am stuck in a place without my books on butterflies.

    Some more for Id.
