Draudt, M. (1917). Heliura. In: Seitz, A. (ed.), The Macrolepidoptera of the
World, vol. 6, The American Bombyces and Sphinges: pp. 169-170 (as Heliura
hoffmannsi). (German edition: Die Gross-Schmetterlinge der Erde 6: 169-170.)

H. hoffmannsi Rothsch. differs from the preceding by the orange abdomen being
yellow-reddish beneath; the vertex and neck are more extensively orange. The
forewings are more greyish-white, of a less yellowish tinge with darker veins
and a marking very much like zonata. Venezuela and North Colombia.

"The preceding" is zonata, which Draudt describes thus (same work, p. 169,
pl. 24 f):

H. zonata Druce (24 f) approximates griseipuncta. The spots of the forewing
are compressed to 3 transverse bands: a basal one, one crossing the
cell-apex, and an apical one being irregularly defined and with lighter,
yellowish patches. Veins distinct and fine black. All the rest as in balium.
Colombia (Rio Negro), Venezuela, Guiana.

The paragraph on balia (balium) that zonata refers to (same work, p. 169,
pl. 24 g):

H. balia Hmps. (24 g) has a greyish-brownish, darker spotted head and thorax;
neck orange. Abdomen red with a black anal apex. Forewings white with
blackish-brown spots, hindwings semi-diaphanous white with a greyish-brownish,
narrow border. Honduras; Costa Rica (San Carlos).
