the World, vol. 6, The American Bombyces and Sphinges: p. 271, pl. 35 f, as
Josiodes mutans.

J. mutans Wkr. (35 f) is sufficiently characterized by the absence of the
subapical band; the orange basal part is broad, upwards somewhat concave
owing to the rounded black costal margin. On the hindwing the proximal margin
and a discal longitudinal stripe are orange. -- maculata form. nov. (= ab. 1
Hmps.) is spotted orange on the collar and mesothorax. Expanse of wings:
36 mm. Amazon.
