C. ladan Druce (= intensa Druce ) (14 i). Near to the preceding. Body blackish-brown; collar and 
base of shoulder-covers with carmine spots; vertex and thorax sparsely scaled in blue. Forehips and venter 
white; the abdomen exhibits above 2 violettish-red, small spots, lateral blue spots; the posterior margins of 
the segments are above more or less bordered with blue. Wings hyaline with black veins, margins, apical and 
proximal angle, as well as discal spots; on the hindwings the discal spots and distal margin are somewhat scaled 
in a metallic blue. Expanse of wings: 30 mm. Panama (Chiriqui). 
30. Genus: Poecilosoma Hbn. 
Like Cosmosoma , but on the forewings the uppermost radial vein rises from below the upper cell-angle. 
Lower half of the cell of the hindwing very small, lower radial and lower median vein on a long footstalk. 
P. chrysis Hbn. ( = megaspila Wkr.) (14 i) looks almost exactly like Cosmosoma ignidorsia (13 b), 
but it is sufficiently marked by the low rising of the uppermost radial vein. Besides the distal half of the shoulder- 
covers is black, spotted blue, and the red lateral spots on the 2nd abdominal ring are absent. Described 
from the Amazon, before me also from French Guiana. 
P. nigerrimum Wkr. (14 i) exhibits a quite black body with metallic blue spots. The comb-like teeth 
on the antennae are reddish-yellow. Wings yellowish hyaline with orange-yellow veins. Amazon (Ega). 
P. eusebia Druce (14 i) has the head and thorax spotted orange-yellow and black; the orange- 
yellow abdomen shows on the first segment some small black spots; on the 2nd and 3rd rings there are black, 
subdorsally blue-spotted transverse bands, the 4th and 5th rings show black, blue-pupilled subdorsal spots, 
the last rings are black. The faintly yellowish hyaline wings are orange at the costal and proximal margin. 
Forehips spotted blue. Ecuador. 
P. eone Hbn. (14 i). Head and thorax are black with silvery bluish-green spots; the forehead and 
stripes on the shoulder-covers are white. The first abdominal ring is carmine with yellowish spots, the two 
next rings exhibit lateral red spots, the rest of the abdomen is black with white dorsal and lateral spots being 
margined by metallic greenish-blue. The base of the proximal margin on the forewing is extensively greenish- 
blue silvery. From the Amazon, Para, Sao Paulo, Santa Catharina. 
P. mapirense Strand. It reminds us of Cosmosoma xanthistis Hmps., but it has more pointed wings 
with a narrower marginal band; the base of the proximal margin of the hindwing is only little orange; base 
of abdomen black, rest of abdomen black with 4 longitudinal rows of bluish-green spots. Collar and shoulder- 
covers orange, the latter bordered with black. Head, breast and hips blue-spotted. Expanse of wings: 28 mm. 
Based upon a rubbed-off <$ from Bolivia. 
P. misionum Strand greatly resembles the preceding, but the 4 anterior abdominal segments are beneath 
and laterally orange, partly also the hindlegs; subcostal space hyaline. The transverse-vein spot of the fore¬ 
wing is broader; the base of the hindwing is more extensively orange-yellow. Antennae at the ends white. 
Whether the abdomen exhibits also green spots, cannot be stated by reason of the defective preservation. 
Expanse of wings: 29 mm. Argentina (Misiones). 
P. marginatum Wkr. (14 i). Body black, forehead, vertex, and thorax with metallic blue spots. Base 
of palpi, collar, shoulder-covers, breast and stripes on the legs orange-red. The abdomen exhibits a dorsal 
row of metallic blue spots and broad, orange-red lateral stripes. Subcostal space of the forewing orange-red. 
From the Amazon District. 
P. vespoides Schaus (14 i) has an entirely orange-yellow body. Black are: the distal side of the terminal 
joint on the palpi, dorsal and lateral spots beginning from the third abdominal ring, stripes on the outside of 
the legs, and the antennae. Base of forewing and subcostal space from the transverse vein as far as the apex 
orange. Margins of wings very narrowly black; a very minute apical spot. Described from Peru; before me 
also in some specimens fron Colombia (Ibaque, 2700 m). 
31. Genus: Mystrocneme H.-Sch'dfj. 
Like the preceding, but the lower half of the cell on the hindwing is of a normal size, and the lower 
radial vein and the lower median vein, therefore, are much shorter pedicellate; the first median vein rising in 
the preceding genus close before the margin, is absent here; the spurs are very short. 
M. varipes Wkr. (= geminata H.-Schaff.) (14 k) is distinguished by peculiar, rough scent-scales on 
the under surface of the wings in the <$, being situate on the lower cell-angle and at the apex of the forewing 
and the distal half of the hindwing; besides, the posterior tibiae of the <$ in the distal half exhibit an enlargement
