since not only tlie upper surface, hut also (he lowei' one differs greatly from the other forms. Wiiether only 

 this form occurs in Lcopoldina, we do not know; most of the forms deserihed ahove are not i)ound to a certain 

 locality. — The grown-uj) larva of stfi<jo.sa has a blackish-grey head, a dull hrownish-green ground-colouring 

 of the l)ody with a reddish tinge, the doival line of a deep black, the otiier dorsal part blackish-green, at the 

 sides there are l)lurred pale stripes. The ])upa is most similar to that of /^eme.s'/.y.

 considerably from that of Protogoniiis. From the latter as well a,s from Aiuteii to which it is closely allied, the 

 under surface likewise differs by its silvery spots. 'I'his genus, being distributed from Ccntial America to South 

 Brazil, contains but few species very similar to eatdi other. Of the early stages only the jjupa is known. I'esem- 

 bling that of Profogonms drurii. According to A. Seitz. the butterfly has a clumsy, irregular, but still hurried 

 flight. The butterflies are to be met nearly all the year round.

We regard all the hitherto described membei's of this genus, being distril)uted from Mexico to South 

 Brazil, as forms of but one s])ecies. U'he arumals are so well charai-terized by their outward appearance that 

 it is quite imj)ossible to confound them with other genera. Although the butterflies exhibit a sight c[uite different 

 from the Anaea, yet, by the inner structure of the butterfly as A\'ell as by the shape and habits of the larva 

 it is evident that they are closely allied to the Auiieu. By the colouring and marking the butterflies greatly 

 resemble certain species of Heikoniii-s from w hich they differ, however, at first sight by tiie very peculiar sliape 

 of the wings. — The larva was known already to the early authors, for Stoll gives the follow ing report about 

 them: ,,The laiva is dark green and has a brown, nearly black stripe across the back, also at the sides 

 such sjiots and stripes (on each of the anterior and jiosterior rings two, on each of the 4 middle rings 3 longi- 

 tudinal stripes, and on the last segment 2 transverse stripes). The feet are dark green. The head has a black 

 i-olour with gree:i stripes and is decorated with two obtuse horns. On the upper ])art of it there are two, and 

 next to the first ring, on Ijotli sides, three yellowish round maculae. It feeds, though only at night, on the 

 leaves of a kind of pepper (Pipei' nigrum). During the day it liides in a leaf, the rims of which it draws 

 in by means of its spinning and rolls it up. It seems to live there like under a roof and to protect itself against 

 the heat of the sun. Atti'r the last skinning it tui'ns into a short stout chrysalis hanging down freely. 

 The latter is of a jjale gi-ey colour marked with brown spots and stripes. The imago appears generally after 

 eleven days." These statements refer to the form from Surinam, hippomi F. According to Sepp. the larva 

 is said to live also on Mespilus americana, whereas the South Brazilian foi'm dnirii Btlr., according to W. 

 Mf^LLER, has been found on Piper gaudichaudii Miqu. The larva of this form differs by the lateral stri])es 

 being flown together into one single broad interrupted sti-ipe which is coloured black-red. The pujia bears 

 on its head 2 very flat coniform appcncUxges, is green diaphanous and on the rings 7 to Id tinged white. 

 The flight of the butterflies, according to A. Seitz, by the irregularity fif the; movements of the wings, 

 reminds us rather of some Safyridne than of that of the Nymphnlidde darting along by jerks with their wings 

 stretched. According to A. Seitz, the genus Pwtogonm.s is doubly protected; while at rest, the butterfly 

 resembles a long-petioled dry leaf, while flying, it agrees w ith Helkonius nnrcaea (72 a).
