    They are all Idea lynceus.

    Idea lynceus.
    Continental forms usually have rounded HWs but variations occur & some have the HW slightly lobed as in I. stolli.
    In nature more smoky & darker than I. stolli.
    The spots are larger ,that in the cell extending beyond the black veins & that on the FW often touching the veins.
    HW with the sub-basal spot in space 1b doubled ,often fused, but the inner one may be much smaller.
    Continental.

    In Borneo I. lynceus have the HWs lobate making it confusing with I. stolli.

    Idea stolli.
    HW always lobate. Whiter in nature.
    Spots smaller ,in cell rarely extending beyond veins & on FW not touching the veins.
    HW sub-basal spot in space 1b single,if doubled the second usually vestigial.
    Continental.
