M. sura Schaus. Palpi and legs black, suffused with metallic blue; posterior tarsi with white ends. 
Head black, on the forehead 2 large white spots, smaller ones below the antennae. The collar exhibits blue 
and white spots; thorax black, shoulder-covers anteriorly spotted blue and white. Abdomen above metallic 
green, beneath black, ventral valve green; the middle of the venter exhibits 2 rows of small white spots. Fore¬ 
wings dull metallic bluish green, a subbasal band and the distal margin black. Hindwings black. Expanse of 
wings: 35 mm. This species described from Brazil has remained unknown to me. 
M. viridifusa Schaus. Head and thorax greenish black, the collar outside and inside bordered with 
white. Abdomen dull green with 2 white lateral spots at the base; a white ventral spot; hips spotted Avhite; 
legs greenish black. Forewings brownish black with dark green veins, costal and proximal margins. Expanse 
of wings: 38 mm. Castro (Parana). 
56. Genus: Pliaeo Neum. 
Animals with very long and narrow wings, with a woolly thorax and abdominal base. On the forewings 
the 1st median vein rises before the lower cell-angle from which the 2 lower radial veins rise, the uppermost 
from the cell. On the hindwing's the lower median and lower radial vein are petioled, the 1st median vein rises 
from the upper one close before the margin. 
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. 
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. 
Ph. aquiguttata Dogn. (17 f) has a black body: forehead and prothorax are metallic greenish-blue; 
each half of the collar exhibits a large, round, white spot, a similar, very large one with a greenish-blue iridescence 
on the metathorax. The first abdominal ring exhibits 2 large white dorsal spots, the other rings show greenish-blue 
bands, the angular membrane is yellowish-white. The brown forewings exhibit below the median a large oval 
hyaline spot, above it in the cell a cuneiform spot and at the upper cell-angle a minute punctiform spot; behind 
the cell an oblique band of 5 hyaline spots, the middle one being very small, in the shape of a streak, the two 
lower ones moved towards the margin. The hindwings being hyaline in the disc exhibit a black margin. From 
Columbia, also from Ecuador. 
Ph. geminiguttata Dogn. (17 f) is not to be confounded owing to the hyaline double spots being peculiarly 
placed behind each other on the fore- and hindwings; the forewings are strewn with golden green scales. Head 
and thorax are black, on the forehead, collar, shoulders, meso- and metathorax white spots. The first black 
abdominal ring exhibits white dorsal and lateral spots, the rest is metallic greenish-blue with white lateral 
stripes quickly narrowing down posteriorly. The antennae are above thickly covered with metallic greenish- 
blue scales. Colombia (San Antonio; Medina). 
Ph. sylva Schaus (17 f) from Brazil (Rio de Janeiro), before us also from Colombia, is a smaller species, 
the wings densely strewn with golden and coppery lustrous scales and with hyaline spots arranged about similarly 
as in cephalena (17 e), though those being situate towards the costal margin are very small. The abdomen, 
with a golden green lustre, has on the first segment a white transverse band, on the other segments bluish- 
withe lateral and sublateral spots. — From Colombia (coll. Fassl) there is a form before me: impellucida form, 
nov. (17 f), in which all the hyaline spots of the forewings are absent, whereas on the hindwings they are present. 
Ph. salmoni Druce (17 g) by the arrangement of the hyaline spots resembles quadriguttata, though 
they are all much smaller.I Head and thorax are black, collar and shoulders spotted white; the metathorax 
exhibits a very large, round, white spot. The golden green abdomen with a black dorsal stripe exhibits on the 
second ring large white spots, on the black under surface there are broad white sublateral stripes. Colombia. 
Ph. albicincta Schaus (17 g). Head and thorax are black; the shaft of the antennae blue. Collar, 
hips and spots at the posterior femora, the 2 first abdominal rings and the whole ventral side are white; the 
abdomen otherwise metallic blue, anal tuft black. The black wings are strewn with small, silvery blue scales 
and the hindwings exhibit below the cell a large oval hyaline spot. Expanse of wings: 46 mm. Ecuador.
