curved costal margin, a strikingly expanded apex and a very concave distal margin of the forewings, and an 
almost straight costal margin and undulated border of the hindwings. The ?@ are also larger corresponding to 
the SS, but with respect to their shape, markings and colouring not essentially different from the typical acon- 
tius-O9. — The larva is, according to the figure, in the last stage green with 4 rows of brown branched spines 
on each segment; the two long horns on the head, branched out in three grades, are of the same colouring, the 
head is black, in the middle white, the ventral part and the legs are dull yellow. The pupa, according to 
the description of W. MUiier, resembles on the whole that of penthia, and like this reacts also upon the influence 
of the hight. 
C. orites Stich. (98 b) from Panama to Peru (?), though there is also a g-specimen from Southern 
Brazil (Santa Catharina) in our possession. The golden-yellow median band of the forewings is in front bordered 
rectilinearly and the androconium of the hindwings is grey-coloured. In the @ the yellow spots are less sharply 
separated than in the aconfiws-Q92. This species, on an average, is also larger than the acontius flying in the 
same districts and there are even very remarkably large specimens among the 99°. — C. acontius and orites also 
differ somewhat in the shape of the male secondary sexual organ, it is, however, possible that the two forms 
might be temporal forms of one and the same species. 
37. Genus: Nessaea Hobn. 
This genus, which only a few years ago was justly separated again from Catonephele by H. StTiIcHEt, 
has but few species differing very little in their exterior. It is distributed from Mexico to the Amazon River. 
Compared with Catonephele there is but little difference in the veins. BATES says about NV. obrinus: ,,This char- 
ming butterfly frequents swampy places in the woods of Para and, with the exception of some districts, is less 
often found in the whole Amazon valley. Its flight is extremely impetuous, but it is fond of resting on leaves 
where a ray of sunshine breaks through the shade.‘ This description apparently applies to all the species of this 
genus. The larva of obrinws was known already to the ancient authors. If the description be right, this larva 
essentially differs from the well-known larvae of Catonephele by the considerably shorter and stronger spines 
on the head and by only one row of spines (instead of 4 as in Catonephele) being, however, on the back. 
N. obrinus L. (99 b) from Guiana, the Amazon and Bolivia, is the most beautiful species of the genus, 
the g being adorned on the hindwings by a broad orange-yellow band, which in other species is seen only 
less developed or not at all. The 9, as already indicated, has not got this orange-yellow band, but it has an 
elongated green spot in the apex of the forewings. — The larva is green, has a dark red lateral stripe, a red 
head with two moderately long branched spines of the same colour and, on each segment of the body, in the 
middle of the dorsum a short green ramose spine. 
N. batesii Pidr. (99), also from Cayenne and the Amazon, differs in the male sex from obrinus by 
having a short straight band instead of the broad yellow band of the hindwings, and by a short green band 
in the apex of the forewings. 
N. aglaura Dbl. and Hew. (99) from Mexico and Guatemala, differs considerably from the preceding 
forms by the quite different position and shape of the yellow band of the hindwings; the under surface, however, 
is quite similar. : 
N. regina Salv. (99 b) from Venezuela and Colombia is on the forewings like aglaura, but the hind- 
wings are unicolorously black, except a small brown spot at the inner angle. The 99 are of a more subdued 
colour (greyish-black) and, like the? of obrinus and hewitsoni, have 2 red-brown little spots in the middle cell 
of the forewings. 
N. hewitsoni Fldr. (99 b) trom Colombia, Ecuador, Peru and the Upper Amazon is above black with 
one green band on each of the wings. The 2 has no green band on the hindwings. 
38. Genus: Mlyseelia Doi. 
The species of this genus are distributed from Mexico to Southern BraziP They are easily to be recog- 
nized by the shape of the wings, for both forewings and hindwings have corners and spikes. By this shape they 
differ from Catonephele in which thus shaped wings do not occur; moreover the Catonephele-species, with 2 
exceptions, are considerably larger. In the Myscelia-species an iridescent-blue upper surface of the go is 
prevalent. As to their veins etc. they are not different from the Catonephele-species. One species, capenas, 
having hitherto been united with Catonephele, has been removed to Myscelia by H. SticuEn. We also place here 
sophronia because, according to its exterior as well as according to the formation of its veins and palps, it better 
belongs here than to Cybdelis. — According to MiiuER the following is to be said about the early stages. Food- 
plant of MW. orsis is Dalechampia triphylla Lam. The egg is about hemispherical, a little oval and, with a broad 
basis, sticks on to the leaf, it has fine transversal stripes, is covered with 10 or 11 longitudinal veins growing
