 white band of the hind^ving is somewhat variable. Although the species is cpiite common even in gardens 

 in the neighbourhood of Rio, especially in damp, shady places, we are still ignorant of its early stages. 

 The insect frequents flowei-s. and is easy to catch. — Minas Geraes southwards to Rio Grande do Sul.

P. proneus Hl/>. (•= phrineus Luc.) ilbi. Both wings \vith narrow white band, the red suh- proneus. 

 marginal spots of the hindwing straight or slightly curved: anal spot not Y-shaped. — ilinas Geraes to 

 Parana; near Rio only in the Organ Mountains. 



P. chamissonia. Both wings with white band, that on the hindwing abbreviated: cell-spot of the 

 hindwing not extending fuiiher towards the base than to the 2. median; red anal spot V-shaped. — The 

 larva is brownish black, with an obhtpie white band, extending lateralh" from the 6. segment to the tubercle 

 on the 7. The pupal stage lasts three w-eeks. The buttertly is very common and is one of the earliest 

 spiing species (August). From August to April there are at least thi-ee generations. — diodorus Hoj^tf. diodorus.

 and .S. Catharina. Near Rio itself the species is absent. In this fomi the fringes are partly black, at least 

 at the extremities of the veins. The specimens with a broad white band on the hindwing may be 

 designated as ab. bunichus Hbn. : these are especially common in Sao Paulo and in the Organ Mountains, bunkhus. 



P. perrhebus. Wings entirely without bands. The larva lives on Aristolochia cihata, and beai-s 

 on aU its segments tubercles which are partly white and partly yellow: an oblique band on the 6. and 

 7. segment is yellow. We know two geographical forms of this species. — In Brazil, from Slo Paulo to 

 Rio Grande do Sul, iu Pai-aguay, and in the neighbouring parts of Argentina, occurs a dark form, in 

 which the head, the palpi, and the submarginal spots on the upper surface of the hindw-ing ai-e distinctly 

 red; this is perrhebus Boisd. (la). — The fonn from Buenos Aires, the province of Entre Rios. And perrhebus. 

 Unigua\-, is damocrates G^uen. It is much paler: the head and palpi are black, and the submarginal spots damocrates. 

 on the upper surface of the hindwing are not bright red. The species is especially common near rivers. 



P. phalaecus Eeic. ilb). The only Aristolochia-Papiho with a spatulate tail which has hitherto been phalaecus. 

 found in tropical America between Costa Rica and Paraguay. The body is veiy hairy. The white band, 

 which traverses both wings, is intersected by black veins. — Eastern Ecuador.

The foUowing forms, which have white marginal spots, we unite as the nenms-gYon^. The species are 

 partly hard to differentiate, especially as the two sexes are often very imlike. Very little is known about the 

 earUer stages. Many of the species inhabit marshy woods, where the larvae Uve on Aristolochia. In conseqnence 

 of the inaccessibility of these forests, quite a number of forms are still verj" rare in collections, and there are cer- 

 tainly still some species which have hitherto escaped the net. Scent-organ of the d" mostly with wliite wool, more 

 rarely with black scales.

 yellow-grey bands or patches; hindwing with area of the same colour, occupying the greater part of the 

 wing. — Massauary, near Maues, Amazon River. Collecting in the neighbourhood of the Anrazon. from 

 Para to the foot of the Andes, seems to be more difficult nowadays than formerly. It is true the steamboat 

 takes the collector from place to place, but in the neighbourhood of the larger settlements there is no 

 longer much for him to seek, and living has become extraordinarily expensive. And it is difficult to find 

 a place near the forest fit to live in and seciu'e against flagrant robbery, and the collector is very
