We unite under this heading all the tailed specimens from I^razil belonging to 

 the present group of iVj(;i7/o, namel}' the forms described as h/sitlioiis, Iiarrisianus, 

 athous, sebast/d/iiis, rinik, pompoinm, and eupatorion, which have hitherto been 

 considered distinct species. Intergradations between the various forms are rather 

 rare. There are no structural differences between them. Fortunately, the absence 

 of structural differences and the occasional occurrence of intermediate examples are 

 not the only reasons which induce us to treat all these different-looking forms as 

 specifically identical. Three of the forms have been bred from one female (by a 

 corresjjondent of Mr. H. Wernicke, of Blasewitz). These forms are pomponius, 

 rarik, and h/slthous — ie.,the forms with comparatively small red subraarginal spots 

 on the hindwing. The various varieties are imitations of species of Papilio feeding 

 on Aristolockia (P. ascanius, agavus, etc.). 



c? ? . Body black ; a grey spot on palpus ; a grey or huffish line ventro-laterally 

 on abdomen in many specimens. Wings densely scaled above ; forewing varying 

 from being all black to being crossed by a broad white band, the band crossing cell, 

 or standing outside cell, or being reduced to a large patch ; a red spot at base, 



often absent. Hindwing with or without white central area ; a series of red 



submarginal spots, variable in size, the last four larger than the upper three, these 

 three often absent ; tail variable in length and width, usually spatulate. 



Underside : forewing paler than above, scales smaller in distal area; two red 



spots at base, one standing in cell and the other before it. Hindwing as black as 



above, no distinct cell-lines, three red basal spots, the posterior one produced into a 

 long line on abdominal fold. 



Genitalia: S. Apical edge of harpe very little produced, broadly rounded; 

 dorso-ventral ridge ending abruptly ventrally, the ventral corner not more elevate 

 than the rest of the ridge ; central process widened at apex, dentate apically and 

 dorso-apically, ventral apical angle marked by a rather prominent tooth, proximally 

 of which there are no other teeth. 



Early stages described by Mr. E. D. Jones, I.e., and Burmeister, I.e.

We arrange the varieties in two groups : 



A. Red submarginal spots of hindwing large, longer than broad above.

c??. White band of forewing broad, continued across cell. On hindwing the 

 band usually reaching to M-, the last partition of the band merged together with the 

 red submarginal patch, the band mostly rather narrower in male than in female, 

 being in the male reduced proximally, the white cell-patch occasionally absent in
