DYNAMINE. By J. Roser. 507 
D. chryseis Bates (101 Af) from the Upper Amazon and Nicaragua has a broad black apical part of 
the forewing. 
D. sosthenes Hew. (101 Af) from Nicaragua has stronger bands on the under surface of the hind- 
wings. It differs above from ines by a narrower margin of the forewings and a broad black anal angle of the 
hindwings. 
b) Under surface of the hindwings with eye-spots. 
With D. setabis Dd/. and Hew. (101 A g) from Bolivia and the Upper Amazon begins the series of species 
bearing eye-spot markings on the under surface of the hindwings; setabis has only one eye-spot being 
placed at the anterior part of the submarginal band. 
D. artemisia 7. (= artimesia Ky.) (101 Ag) from South Brazil and Bolivia is a small species, in 
the male sex above verdigris or glossy bluish. The 2 resembles the 9 of egaea, it has, however, smaller white 
spots and narrower white bands. : 
D. neoris Hew. from the Amazon has a verdigris upper surface with diaphanous marking of the 
under surface, uniform entire black margin of the hindwings and very much curved black distal margin as 
well as a black triangular spot in the centre of the costal margin of the forewings. The under surface has 
white ground-colouring, on the hindwings there are 4 yellowish-brown stripes the outer one of which has, on 
the outside, 3 blue eye-spots surrounded by black, the distal margin being also yellowish-brown, parted by 
a blue line. The forewings have yellowish-brown marking on the distal margin, at the basal part of the costal 
margin and at the costal margin near the apex of the wing, as well as in the centre black marking forming 
a circle near the distal angle. 
D. thalassina Bsd. (= immarginata G. and S.) (101 Ag) from Central America and Colombia, has 
a green-shining upper surface with black margins being, however, visible on the forewings only in a certain 
exposure. 
D. pebana Sigr. (101 Agh) from Pebas is smaller than egaea, resembling it, however, above. The 
marking of the under surface is rather different, as seen from the figure. The Q is still unknown. 
D. onias Hew. (101 Ag) from the Amazon exhibits a verdigris upper surface with dark brown distal 
margin, occupying on the forewings the whole apical third and forming a four-cornered spot in the distal angle. 
On the forewings, the white median spots of the under surface are diaphanous. The under surface of the hind- 
wings exhibits white ground-colouring with 4 brown bands of which the middle one is parted by a blue stripe, 
the distal one having 2 blue eye-spots. The under surface of the forewings is black to a great extent, the basal 
part brown; in the black part there are 4 white spots, and small blue spots are at the inner margin, in 
the middle of the distal margin, and a blue submarginal line borders the brown distal margin. The 9 is brown- 
ish-black, with a moderately broad white median band and a white subbasal band of the hindwings, which 
are also provided with a submarginal bluish line. The forewings have 7 white spots varying in size. 
D. mylitta Cr. (= postverta Cr.) (101 Ah) *) is nowheres rare in the whole neotropical region. — 
In ab. bipupillata Sigr. i. 1. the under surface of the hindwings lacks the blue-shining spot behind the second 
eye-spot in the anal angle. According to the observations of W. MtLueRr the small larvae crept out on 
the 5 th of November, the butterflies on the 1st of December. The larva is, in the last stage, rather short 
and broad, not like most of the Nymphalidae entirely cylindrical, thus resembling on the whole more the habitus 
of an Erycinidae-larva than that of a Nymphalidae-larva. The spines are in general as in tithia. In the 3 last 
stages the larva is of a pale green with white dorsal stripes, the spines are also green, the ball-ended bristles 
glassy diaphanous. In the 5th stage there is also a darker brownish-black form found beside the light form, 
which has, however, been observed only in captivity. The larva has the same habits and the same food-plants 
as tithia (ci. p. 505). The pupa is either light-green or light-brown, tolerably slender, the wing-partings are 
closely appressed; it has 2 short coniform horns, 2 strong projectures at the second and fifth segments, both 
are two-pointed at the ends, small not paired tips are at the anterior margin of the segments 6 to 10, 
there is also a strong edge of the wings present. It has 3 movable connections of the segments and is only 
movable to the sides, showing the following brownish markings: a stigma-stripe effaced towards above, a 
distinctly circumscribed spot on the 7th segment in the middle line and 2 lines at the bottom of the wings, wings 
and head being of dark colour. 
Dz. paulina Bates from the Upper Amazon is nearly just as large and above nearly of the same 
colouring and markings, as vicaria, the under surface, however, resembles that of mylitta, though darker. 
D. egaea Ff. (= serina F.) (101 Ah) from Paraguay (and from the Upper Amazon?) resembles a 
great deal mylitta, though it has a narrower black margin of the hindwings and broader black marginal mar- 
kings on the upper surface of the forewings. The 2 has broader white bands and spots than the Q of mylitta. 

*) The valve of D. mylitta Cr. is of a peculiar shape, being at the base expanded like a board with a slight 
depression in the centre and antler-like end, the three tips of which remind us in some way of the Lycaenidae-genus 
Lampides (especially of ZL. celeno). (H. FRUHSTORFER.)
