Phaio quadriguttata sp. nov. -- 47 mm. -- Palpi black with a tuft of white
hairs at the base; antennae and vertex black; frons black dotted with
white on each side; collar black with three white points, a median and
two submedian ones; patagia black; first segment crossed dorsally by a
band of white hairs; upperside of the abdomen strewn with metallic blue
scales, with a fine white lateral edging and the anal tuft black; venter
white bordered with black on each side; coxae furnished with long white
hairs; legs black, the second pair dotted with white at the first joint,
the third pair with the base and the inner side of the femora white.
Forewings with a white basal costal tuft, the upperside black strewn with
metallic bronzy-green scales on the first half and the central inner
region, and with the following four hyaline spots with pearly reflections:
an elongate submedian spot preceding vein 2 (larger); two small rounded
spots, the first at the upper apex of the cell, the second at the origin
of 6 and 7; the fourth rounded and of medium size at the origin of 3 and
4. Upperside of the hindwings black strewn with a few metallic scales,
with four hyaline spots: the first, larger and elongate, submedian, two
extracellular ones at the origin between 4 and 6 and a very small one at
the origin of 3 and 4. Fringes black. Underside similar; the forewings
with the hook of the frenulum white, the hindwings entirely covered with
metallic atoms, bronzy green in the costal region, blue-green elsewhere.

above and lateral and ventral white stripes except at extremity. Fore
wing black suffused with metallic green, the apical area slightly
irrorated with green; an elliptical hyaline spot below middle of cell,
round spots in and beyond upper extremity of cell and beyond lower
extremity. Hind wing black; a hyaline patch below the cell, two elongate
marks beyond the cell and a small spot in fork of veins 2 and 4; the

of the World, vol. 6, The American Bombyces and Sphinges: p. 106,
pl. 17 e.

Ph. quadriguttata Dogn. (17 e) greatly resembles the preceding and is to
be distinguished by the very long-stretched submedian hyaline spot, by the
absence of the spots between the lower radials and below the 1st radial
vein as well as by the much greater extent of the golden green scaling on
the forewings; on the hindwings there is another minute hyaline spot
between the upper median and lower radial vein. Ecuador and Colombia.

"The preceding" is Ph. cephalena Druce, which Draudt describes thus
(p. 106, pl. 17 e):

Ph. cephalena Druce (17 e). Head and thorax are black with white dots on
the head, collar and shoulders; the abdomen is metallic bluish-green with
white lateral stripes and a white band across the first segment. The
blackish-brown wings being provided with hyaline spots exhibit in the
basal part of the forewing a golden green spot, between the lower median
and lower radial vein a more bluish-green, large spot. The antennae
exhibit above a trimming of scales. Colombia, Ecuador.
