of the World, vol. 6, The American Bombyces and Sphinges: p. 45 (plate
reference "27 h" added in the Additions and Corrections, p. 197).

H. trizona Dogn. approximates the preceding: body black, palpal base
laterally white-spotted, on the shoulder-covers a metallic blue dot,
forehips white; the 3 first abdominal segments exhibit fine, light yellow
rings. The hyaline wings, somewhat milky and blue iridescent, are finely
bordered by black, with black veins, at the transverse vein broader
black, as well as at the proximal angle of the hindwing. Expanse of
wings: 40 mm. Venezuela (Merida).

"The preceding" is staminea Draudt (renamed albizonata Dogn. in the
Additions and Corrections, p. 197; a synonym of trizona), which Draudt
describes thus (p. 45):

H. staminea spec. nov. (11 a). Body black. On the collar and the
shoulder-covers on each side a white, metallic-blue opalescent spot, a
similar one in the middle of the metathorax. The first abdominal ring
exhibits above 4 large white spots, the 2nd and 3rd rings are above
unicolorously mealy light-yellow, in another male snow-white, beneath
black. Ventral valve silvery white, from its lateral margins there emerge
dense heaps of yellowish-grey woolly threads wrapping up the whole legs.
Wings hyaline with narrow black margins and veins. The black margin of
the hindwing projects proximally like a tooth between the proximal
margin and vein 1, as well as between this and the lower median vein.
Forehips white, hind tibiae white-spotted. One male specimen originates
from East Colombia (Upper Rio Negro), a second male from Bolivia (Rio
Songo, Fassl).
