DYSDAEMONIA. By Dr. M. Draudt. 
5. Genus: Dysdaemoniii 
Easily recognizable by the hindwing showing longer tails in the <$, shorter ones in the $. Eorewing 
with a long extended apex below which a long angle follows on vein 6, below it the margin of the wing is 
mostly undulately dentate, rarely smoothly margined. In the <$<$, veins 3 and 4 terminate into the tail which 
is spatulately widened at the end, whilst the $$ mostly show only a shoi’t angle here. The genus is divided 
into 2 well separated groups, for the second of which the name Paradaemonia was proposed by Bouvier. Here 
the hyaline spot being present in the first group is absent and the tail ends more pointedly, not spatulately 
widened. <$ antennae serrately ciliated. 
Sectio I: with hyaline spots and a spatulate tail (. Dysdaemonia Hbn.). 
Type: boreas Gr. 
D. boreas Gr. ( = auster Fldr., aristor Rothsch.) (128 b). A common species distributed from Mexico boreas. 
to Paraguay. Forewing brownish or bluish ash-grey with 3 blackish-brown transverse lines and 2 vitreous 
spots at the cell-end, which are spotted blackish-brown inwards. Hindwing with but one small round vitreous 
spot, behind it 3 transverse lines, the outermost being bluish-black and arcuately extending from the anal 
angle into the tail. Colouring and size most variable. From the Berlin Museum there are 2 $$ before me with 
an ivory white ground-colour, from Novo Friburgo; other specimens exhibit a band-like, mostly reddish-brown 
darkening between the 2nd and 3rd transverse lines, and a distinct or indistinct, twice notched shadow may 
occur between the 1st and 2nd transverse lines. — brasiliensis Rothsch. differs—- though not invariably — in the brasiliensis- 
curved submarginal line being extinct towards the tail. Rio de Janeiro and more to the south. The full-grown 
larva with a strongly inflated 3rd ring has no thorns, it is green, often marked violet. It lives on Bombax ceiba. 
D. fosteri Rothsch. (128 b) is very similarly marked, easily discernible by a large round, dark-edged fosteri. 
hyaline spot on the hindwing. In the nomenclatural type the ground-colour is reddish-yellow, with olive green 
lines and bands. An extremely variable species, particularly the ground-colour may vary from a silvery or 
ashy grey (— jordani Giac.) through all kinds of brownish tints (— cortesi Giac.) to a pure green (— viridis jordani. 
K. John) (128 b); darkenings may occur between the two antemedian lines and between the postmedian and Midis' 
subterminal lines, so that sometimes very dark bands may be present (— forms of fasciata K. John) (128 c). fasciata. 
The vitreous spots on the forewing may be very large, and there may be three of them. Larva green, in its 
youth with red-brown, white-curled thorns, adult with a white lateral stripe above which, on the 6th and 9th 
rings, there are white, reel-spotted spots; the 4th ring is strongly raised, as in the larva of Aglia tau. It lives 
on Sama and Chorisia speciosa. 
D. tamerlan M. & W. (128 a) is a large species, light reddish-brown with indistinct transverse lines and tamerlan. 
bands, similar to boreas ; the two exterior transverse lines close together at the inner margin, behind them 
greenish spots, bordered with whitish, in the lower half; a large greenish brown trapezoid spot before the apex 
at the costal margin, 2 small hyaline spots at the cell-end, inside connected by a dark strigiform spot. The $ 
is mostly more distinctly marked. Guiana to Southern Brazil. A very distinctly marked form, from Western 
Colombia (Bella Vista), e Coll. Niepelt, exhibits exactly the same ashy grey colouring as boreas, with green- 
tinted lines and bands: — Columbiana /. n. columbiana. 
D. lemoulti Schs. shows a more notched margin than tamerlan. Ground-colour greyish-brown with a lemoulti. 
green tint, the markings as in tamerlan except the distal transverse lines which are more undulated and mostly 
show but one small hyaline spot at the cell-end, behind which there is a large irregular velvety brown spot; 
the dark subapical spot at the costal margin is triangular. French Guiana; Western Colombia. 
D. nobilis Schs. (128 a) is likewise very similar, very large, with a very much produced apex, and the nobilis. 
distal margin still more notched, greenish-grey, the transverse lines and shadows darker grey, a large round 
hyaline spot at the cell-encl and a very small one above it, with deep brown spots behind it. Postmedian shadow 
green; submarginal spots deep green bordered by white strewing. Costa Rica. 
D. timur Weym. is easily separated from all the preceding species by the brightly contrasting dark timur. 
submarginal band in both wings; antemedian band of forewing shaped as in tamerlan-, at the cell-end only a 
small hyaline spot in a long dark strigiform spot which projects distally somewhat like a tooth. Colombia 
(Villa vicencio). 
Sectio II: without hyaline spots, with a more pointed tail: Paradaemonia Bouv. 
Type: pluto Westiv.

confusion of the synonymy. According to the kind information by Dr. Jordan who compared the types, 
all the three names belong to one and the same species from South-Eastern Brazil, the statement of the patria
