91 S CTIANOPHA; PROELYMIOTIS. By Dr. M. Draudt. 
E. boisil Schs. Head and thorax blackish-brown, only the collar and metathorax brownish cinnamon- 
coloured. Forewing light brownish cinnamon-coloured; dark undulated double antemedian lines, a thick velvety 
black line behind them at the inner margin, bent up to the cross-vein and extending along 5 almost to the 
margin, where two small black spots are above it; the line has yet a triangular continuation downward across 
the median fold, and a tiny silvery white spot near the end with a continuation towards the base; cliscal veins 
strewn with black and white; white marginal dots on the ends of the veins. Hindwing white, broadly cinnamon- 
brown at the margin. Expanse of wings: 45 mm. French Guiana; Amazons (Teffe).

Structure like that of Elymiotis , but with broader wings which show a distinct angle at the somewhat 
dentate distal margin on vein 3. The second joint of the palpus is longer than in Elymiotis, and the collar 
exhibits tufts of scales. The neuration is the same, but vein 6 of hindwing is always more distinctly stalked 
with 7. 4 species are known so far. 
Type of the genus: C. argyria Btlr. 
C. argyria Btlr. is similar to the species of the genus Calledema ; forewing reddish-brown, with indistinct 
darker double transverse lines, a dark dot at the cell-end in the lower angle, a silvery stripe extends from this 
dot to the centre of the distal margin and cuts the lighter undulate linear shading which comes down in 3 
inwardly curved bows; the latter shading despatches downward three branches to the 3 lowest marginal veins. 
Hindwing brownish-grey. Brasil. 
C. argentilinea Schs. is yellowish bay on the forewing, strewn with darker brown, dusted with green 
at the costal margin, in the distal half of the cell and in a spot before the centre below the cell; transverse lines 
marked darker; a streak on the distal half of the median vein and the cross-vein are silvery white, a submarginal 
row of black spots, brown internerval streaks on the margin. Hindwing red-brown, lighter towards the base 
with a black anal spot which is parted by white. Expanse of wings: 32 mm. French Guiana. 
C. serena Schs. is similar,'with the same green spots, but the ground-colour is lilac grey, only the brown 
cross-vein is narrowly bordered with silvery white outside, with yellow inside; the transverse lines are much 
less distinct, only formed of darker strewing; a brown spot is before the lowest black submarginal spots. Hind¬ 
wing as in argentilinea. Expanse of wings: 32 mm. British Guiana. 
C. lilacina sp. n. (144 g). Forewing light lilac grey, strewn with blackish-brown, double undulate- 
dentate transverse lines are marked by denser strewing, the posterior line is followed by black and white vein- 
dots; a narrow, brownish-grey reniform macula bordered with white is at the cell-end, a darker spot before it in 
the cell; dense blackish-brown strewing before the undulate line; a fine light crescentiform line in the marginal 
area which is more densely strewn with blackish-grey. Hindwing greyish-brown, a black spot parted by white 
is at the anal angle. 1 S from Thonrar: Berlin Museum. 
21. Genus: I*roelyiuiotis Schs. 
Separated from the closely allied Elymiotis by a very high tuft of hair-scales on the frons; palpi porrect, 
with a longer middle joint. The neuration scarcely differs from that of the two preceding genera. A number of 
species with a very different exterior have been described. 
Type of the genus: P. aequipars Wkr. 
P. aequipars Wkr. ( = serniniva Wkr., divisa Mschlr.) (144 g) is a very characteristic, common and 
widely distributed animal with yellowish whitish-grey forewings, dark blackish-brown in the basal half and a 
costal spot behind the centre, the distal portion traversed by numerous double fine dark transverse lines; a 
finely margined irregular reniform macula; small slate-black spots before the margin. Hindwing brownish, 
dark brown on the margin and veins. Mexico to Peru and Brazil. 
P. similis sp. n. (144 g) is exceedingly similar to aequipars, easily discernible by the white, thinly scaled 
hindwings with a narrowly smoked margin and veins; basal area mixed with a somewhat lighter reddish-brown 
colour, the border-line distally extending more vertically to the inner margin; distal area purely silvery white, 
scantily strewn with blackish, with a narrow reniform macula which shows three distal notches, at the cell-end; 
a fine notched white subterminal line is before the very distinct fine black submarginal line, fine black pointed 
arrow-shaped spots are on its proximal side, similar pointed spots are before the fringe, the points extending 
into the fringe. 1 from Petropolis, type in the Berlin Museum. 
P. severina Schs. Frons white, spotted black, thorax black except the collar, which is cinnamon-brown 
in front, and the similarly coloured basal tuft of the antenna. Basal half of forewing of a deep slaty brown
