narrow but distinctly higher towards the top, not reaching, however, the pole; the eggs are singly stuck to the 
lower surface of the leaves. In the last stage the larva is 16 to 28 mm long, the head is green from each side of 
which, like antlers, there rises a horn of about three times the diameter of the head. These light-brown 
horns are in two places shortly ramulous, and on their top there is a star-like formation (rosette), the segments 
of the body show short branched green spines in varying numbers, the body is green with numerous white papillae; 
after the 1. or 2. skinning the animal, when at rest, takes up a position in which the body in its entire length 
is lying flat on the leaf, the head being lowered in such a way that the points of the horns are touching the leaf 
(defensive position). During the first two stages the little larva gnaws off the leaf as far as the ribs on 
which it deposits its faeces. The pupa is somewhat flattened out, especially at the posterior parts, on the dorsum, 
except the 2. segment, without any edge, appearing therefore, when seen laterally, rather slender, from above 
especially in the region of the segments 5—7 broad, from here towards the front a little, towards the back con- 
siderably reduced in width; it is little tuberous, 2 short conical points at the head, a tapering edge on the 2. 
segment, a very prominent, smooth edge of the wings,-3 movable connections of the segments, rather freely 
movable in all directions, the end of the abdomen is like in Ageronia broad, flattened down. The pupa is fastened 
to the upper surface of the leaves, raises itself under the effect of the light and turns itself towards the light. 
— A. Srrrz reports about the butterflies: The ¢ of I. orsis most positively belongs to the most magnificent 
sights. The sparkling blue colour attracts even the glances of those who are not specially interested in nature. 
The living specimen never exhibits the large shining grey spot at the inner margin of the hindwings, which dis- 
figures the prepared butterfly, for even in its swiftest flight the orsis never raises its forewings so high that this 
spot would become visible. The 3 of orsis is very frequently seen (near Rio). Everywhere in the woods, on 
wet roads, on bushes, at little clearings they are resting in wait at the ends of branches and they occur in 
most any season of the year. In Sao Paulo, I do not remember of having returned from any of my numerous 
excursions without having found some specimens of orsis, although I never saw many of them together. The 
O° of this species remind us a great deal of some Neptis; but while the Indian species of the latter genus 
particularly rested on flowers, I never noticed the like in the Myscelia-29. The latter always settle on leaves, 
the 99 fluttering indefatigably from one leaf to another and resting on each of them but forseconds. If onechases 
them, they retire into the interior of the bushes (while the other Nymphalidae, quite on the contrary, fly out 
of them when being pursued); this strange conduct is, of all the day-butterflies, experienced but in the Brasso- 
lidae and some Satyridae. 
M. orsis Dru. (98f) is the best known species from Brazil; there is a considerable difference in the 
sexes. Like the following species, the g has an androconium consisting of a black spot near the costal margin 
of the hindwings and in a corresponding blank friction-area, on the under surface of the forewings, being accom- 
panied by a ventricose expansion of the inner margin of the forewings. 
M. cyanomelas spec. nov. (98 f) from the Lower Amazon (Santarem) has a much darker (brown) under 
surface with bluish-whitish markings. 
M. cyaniris Dbl. and Hew. (99 a), distributed from Mexico to Venezuela, is a rare species. The 4 is 
of a bright iridescent blue. The light markings are in the non-iridescent 2 either whitish or bluish. 
M. ethusa Bsd. (99 a) from Mexico has only shining blue stripes, but no reflection. 
M. rogenhoferi Fldr. (99 a) from Mexico, which is known to us only from the figure, is presumably a 
temporal or local form of ethusa from which it differs by more violet striate markings and larger white spots 
on the forewings. 
_ M. pattenia Bétlr. and Druce from Costa Rica resembles ethusa, but the markings are more greenish- 
blue and the second and third blue bands of the hindwings are narrower and nearer to each other. The white 
spots on the forewings are more strictly separated. 
M. leucocyana Fidr. (99 a) from Venezuela has markings shining in blue on the wings and also whitish 
spots on the forewings. 
M. cyananthe Fidr. (99 a) from Mexico has likewise blue-shining, but much broader markings; there 
are no white markings. 
M. skinneri Mengel from Mexico (Boyemena, Sinoloa) has not become known to us. It is described: 
Ground-colouring of the whole upper surface black, along the inner margin of the hindwings little lighter. Be- 
ginning at the base of the forewings there stands a purple spot extending more than 3/, inch in the middle cell, 
nearly %4 inch in the wings. Along the margin of the wings there runs a line of white or light-blue spots, 
broken along the whole margin. There is a parallel line of spots of similar colouring, though somewhat darker, 
running close to the angle. Here there are two white apical spots surrounded by a very fine blue shine, 3 sub- 
marginal spots and 2 in the centre of the costal margin of the same colouring. The hindwings are rounded with a 
thin, broken line of white spots running along the angle. A broad spot of the same purple colour as on the fore-
