536 PANAOEA. By Dr. A. Seitz. 



its horns on the head are more curved than in tlie allied genera. The pui3a with hare'.s ear.s at the head which 

 are somewhat shorter and broader than in Ageronia. The butterflies are met either resting on trunks or lying 

 on them in spirals. Contrary to the Ageronia they seem not to be able to rattle, at least I have never heard 

 them making a noise. The range extends over the whole warmer distritcs of South America from Nicaragua 

 to Southern Brazil and Paraguay. The forms of this genus are very nearly allied to each other, and as the 

 older descriptions are inaccurate and the habitat is often not mentioned, the relations of the older names 

 to the forms that are known now, are not always traceable. 

 irrfifd.tria. N. rcctifascia Btlr. and Dr. (? = lirinei F Mr., erycinoides i^/c?r.) (103 a). This northernmost species 



distributed across the whole southern part of Clentral America from Nicaragua to Panama, is at once recogni- 

 zable by the relatively narrow, interiorly always smoothly cut off oblique band of the forewing. The ground- 

 colour of the wings is rather light nut-brown without any metal lustre. 

 /,•,.;„. A. liria F. (103 a). This species appears to me to represent the Venezuelan form probably also flying 



in Guiana. The oblique band is as broad again, ending broad over the inner-angle in the margin; the under 

 surface is much lighter, the upper surface shows in the sun unnoticeable, though subdued and dull violet reflec-

 Fruhst.); the upper surface is rather dark and is somewhat lustrous in the sunshine, but without a real blue

 with the sombre ground-colour, and the rather smoothly edged band of the forewing terminates very broadly 

 on the lower median vein; the under surface more drab than yellowish-brown and with insignificant markings. — 

 (i.ilr'iiiii. astricta Fruhst. from Peru exhibits above in both the sexes blue gloss, and the white oblique band of the fore- 

 wings terminates into a kind of a cone owing to deep mdenture; the black bands darker and placed more 

 vertically. — Larva on Dalechampia ; pupa brown with pale spots ; beginning from ring 5 a light dorsal stripe. 

 The butterflies are mostly common at clearings in the woods; when being chased away from a trunk, they 

 generally fly in a straight flight to the nearest trunk, evidently showing a slight similarity in the flight with 

 the $ of Emesis fastidiosa; the latter, however, never rests on the trunks of trees, but on the under surface 

 of the leaves.

into single white spots. The (^ has a brighter blue gloss. From Peru to the Lower Amazon; seems to be rarer. 



h2. Genus: l*aiiacca *S'. and G. 



These butterflies usually exhibit on the upper surface green bands with metallic lustre, representing 

 in the basal part of the hindwings a complicated parallel stream, being then terminated by a coherent metal- 

 l)and. Like in the Ageronia to which the genus is evidently closely allied *), the under surface may be hemo- 

 chrome or also dull-coloured. The genus Avas formerly confounded with the following Batesia, but the only 

 species forming the latter genus differs so considerably that it better remains separated. In Batesia the upper 

 radial of the forewing forms a curve being downwards concave, upwards convex, being thus just the reverse 

 of the lowest radial, so that both are divergent anteriorly and posteriorly and approaching each other 

 in the middle, while the second radial passes through in the midst between the two. In this way about the 

 following .strange figure is formed: ~, being the more conspicuous, as it stands in an enormous hemochrome 

 spot. In the Panacea the course of the raclials is normal, nearly parallel; the forewings are here also mucli 

 more pointed, their distal margin centrally drawn in etc. We do not know anything about the early stages; 

 the butterflies are fond of the mountains, are in some parts common and have similar habits as the Age- 

 ronia. The single species vary extremely, but less geographically than individually, and to such an extent that 

 almost all the species ai-e connected with each other by certain transitions. The under surface of the apex is 

 either hemochrome or black or yellow, the hindwings are sometimes marked with diffuse .spots beneath, with 

 Ihies, or figures, or even not marked at all. 

 proriihi. p. procilla Hew. (103 c) is the .species which beside prola being scarlet beneath comes the most frequently 



to us. It has beneath black forewings with reddish-brown or dark greyish-brown apical part being cut off by 

 a white oblique band; the cellule is striped brown or blue, the hindwings are of a reddish-brown, marked in 

 l)lack. In Colombia, not rare, common in the so-called ,, Bogota-Collections". A. H. Fassl has made some 

 observations about their habits. According to him the egg is very small, like that of Satyrus briseis, like a ball, 

 somewhat tapering towards the upper pole, the smooth base oblate. The sides bear 12 vertical indentations 

 terminating shortly before the top into projecting tips like calyces. The colour of the egg is reddish-brown. 

 — procilla, in many places of Colombia at altitudes between 4 and 1200 m, belongs to the more frequently 

 occurring butterflies. While the (J often drinks in numbers from the excrements of the roads in the primeval 

 forests, the large $ differing considerably especially beneath, is a great rarity. ■procilla-(^,^ (as well as other 

 Panacea- and Peridromia-s}iecies) when being disturbed in their meal, usually fly as far as to the neighbouring 

 trunk of a tree in order to rest sitting there in wait, mostly in considerable height with their wings spread 

 out and their heads downwards, until the intruder has passed by, whereii])on they return to the very same
