Ph. heiicooides H.-Srhajf. (]2Sa. b). Wings hyaline with hhxek veins and margins, the forewings hrllronhl^ 

 with an oblique hand across the cell-end. Middle of the forehead silvery white. Imitates species ol Hypoleria 

 and Ithomia. From Guiana and the Amazon. - In rufula S)n. from Ecuador the hyaline patches of the distal niiuia.

 the orange is noticed also at the posterioi' end of the hyaline patches in the hindwing. \ot rare. 



27. Genus: Isa]j»is Dhl. 



This genus contains only 1 species which, however, is very widely distributed, although it occurs spora- 

 dically. The head is broad with very thick eyes, a flat forehead, short palpi and thick antennae ending with 

 long and stout, fusiform clubs. The forewings are long with a round margin and a little marked anal angle. 



I. agyrtws Cr. (132 c). Black, forewing with an orange-yellov.- oblicpie spot; beneath a yellow transverse (uii/rhis. 

 band runs across the basal part of both wings as far as to the anal angle of the hindwing, where it is in 

 some $2 still to be seen round the inner margin as a small narrow, yellow inner marginal stripe on the upper 

 surface. It varies at every habitat, though not according to countries, as for instance on the Amazon there 

 occur specimens with a broad and a narrow band of the undt»r surface, as well as in Surinam etc. Specimens 

 from Santos have a deep orange-red stripe of the forewing, turning sowewhat distally at the costal margin, 

 and a moderately broad band of the under surface. We have considered this form to be sestus Stirh. and figured se.flKs. 

 by this name, owing to the author's statement ,, Brazil, Bolivia"; but as the author states, his se.sius corresponds 

 with our figure of mithrophorus (132 c), vvhich, however, represents a Surinam specimen. — $2 with a yellow 

 inner marginal border of the hindwing, as they are before me from Bolivia, Stichel denominates praxinus. iiriuhius.

 band of the under surface as thin as a thread, from Colombia, the 9? of which exJiibit besides a ,,Iess band-like •'"'''''■• 

 band of the forewing". The butterflies are very local, but not rare at their flying-places. They sit on the tips 

 of twigs with their wings clapped together, and are particularly fond to do so on small bare branches, on the 

 upper surface, the antennae stretched forward parallel in the diiection of the clearing in the woods; on being 

 chased up they fly only a few metres off. The range extends from Central America to Bolivia and South Brazil. 



28. Gemi.s: IPaiisurji, Dhl. 



This genus ha.^ 2 species being rather near to each other. They are black animals with an orange oblique 

 band of the forewing, as we find it also in Lsapis and many other Erycinidae, whereby resemblance.-; are pro- 

 duced with the said genus, as well as with species of Me.se ne, Aricoris, C'hnmaelimvns, Lymnns etc. The animals 

 are rather strongly built and exceptionally good flyers and also sometimes fly about in day-time, the flight 

 being somewhat like that of Heterorera, so that they are difficult to distinguish from cpiite a number of homo- 

 iogically coloured species of Geometrids and Arctiids found at the same places. In the hindwing the cell is 

 possibly still shorter than in most of the other Erycinidae; on the forewing the first subcostal vein branches 

 off just before the cell-end, the second directly behind it. Although the Initterflies are not so local as the other 

 Erycinidae. their life-history is not known. 



P. phereclus L. ( 1 32 c). Only the forewings exhibit an orange band being situated sometimes more steeply, pimrHu.^. 

 sometimes more flatly, and varying at every habitat. It generally (in specimens from the .Amazon) reaches almost 

 the costa and anal angle. — barsacus Wir. (I32c), with a somewhat shorter orange band, is connected with hf,rsf«».s-. 

 pherechts by all transitions and ought not to have been separated. Amazon, Guiana. Some specimens, especially 

 $2, have in the hindwing white or chequered fringes, being, however, quite accidental. — conies Stich. originates roiDrx. 

 from Peru, Ecuador, and Bolivia, but docs not differ constantly from the tvpical form, neither by the fringes 

 nor by the size, as the species varies everywhere in this respect. — ab. lemniscata TJwi. are specimens (before irnniixraU,. 

 me are only $9 from Colombia) with a white oblique band of the forewing. — episatnius Pritiir. (? sicora Heii\) rpisafuinx.

P. thisbe F. (= iarbas V/ir. nee F.. perdita Hbv.) (132d). This ,speci.-s hps longer hindwings and on '/"■'-■'"■• 

 them also an orange band forming with that of the forewing nearly a right angle. In typical specimens (generally 

 found in Guiana and North Brazil) both the orange bands are rather narrow . In soaita Hew. ( 132 d) froin South .■^orinri.

 curved. — In thymele Stich. from South Brazil the band of the forewing lies more flatly, that of the hindwing l/i//""/''- 

 is placed somewhat distally; this is of course only the character oi the flying-place, as specimens from different 

 habitats always exhibit differences of the bands. — ovifera form. nov. (132 d) from Petropolis in Soutli Brazil 'iri/rra.
