broad, much broailer tban in P. helios, aJmargiual and snbmarginal spots yellowisb, 

 but paler than in P. helios, all small, j'ellow aiial marginal spot separated from 

 snbmarginal spot M' — M-, the vein M'- being black ; red anal spot ver)' large, 

 yellowish spot M' — M- behind it reduced to a minute bar, black spot M'— M' 

 contiguous with the red patch ; blue spots R' — M- rather large, but not sharply 

 defined i)ro.\imally ; marginal teeth C — ]{-' sharp, distal edge of wing black from 

 C to tail, there being only a minute yellowish spot close to the margin in front 

 of tail. 



Underside more green at base than in P. helios ; anal and subanal pinkish 

 spots of hindwing large ; black line along abdominal edge extending to anal 

 angle, postdiscal band broad, yellowish ad- and snbmarginal spots narrow. 



? not known. 



Scent-organ as in P. protesilaus. 



Genitalia as in P. helios, but apical lobe of harpe much shorter and broader, 

 rounded at apex ; ventral process also shorter. 



Ilab. Paraguay ; Brazil. 



A c? in coll. Weymer, from Paraguay. The type-specimen, also from 

 Paraguay, is no longer in coll. Fruhstorfer; we have been unable to find out in 

 which collection it is now contained ; the bands, especially the marginal one of 

 the forewing, are narrower than in our iigiirc, according to a sketch which 

 Herr G. Weymer has kindly sent us. 



The 6 here figured is from Goyaz, Brazil, in coll. Obertliilr.

cJ ? . Antenna Idack. Frons wliite at sides. Transparent area of forewing 

 much more extended than in P. protesilaus and P. telesilaus, the opaque (densely 

 white-scaled) area reaching from hinder margin to M-, not entering cell ; the scales 

 of this opaque space narrow, sinuate, becoming more and more narrow towards 

 cell and in basal half of cell, assuming a hairlike shape in the apical half of 

 the wing ; the white scales at the costal edge between the black bands about the 

 same size as those in the posterior area of the wing ; the hairlike scales of 

 the transparent spaces usually fallen off to a great extent; the scales of the 

 black bands about twice or three times as long as broad, denticulate, some 

 narrow; scaling of rmderside as above, but transparent spaces practically denuded 

 of scales, the sockets of the scales, however, being present ; scales larger than 

 above and entire from M^ to inner margin, except distally ; seven comparatively 

 thin black bands, the first not quite reaching inner margin, stoi)ping at vSM', 

 the second extending usually beyond SM-, but never reaching inner margin, a little 

 more oblique and therefore posteriorly more distal than in telesilaus ; interspace 

 between these two bands about half as wide again as that between second and 

 third band, the latter stopping at M, fourth band reduced to a costal spot, usually 

 triangular, rarely reaching halfway across the cell, fifth and sixth bauds usually 

 touching each other at lower angle of cell, seldom here li mm. distant, sixth 

 always reaching to hinder angle, here joining the marginal band; transparent 

 snbmarginal band reaching costally beyond SO' and posteriorly beyon<l M", there 



being in black costal border a thin transparent streak before SO''. Hindwing 



more elongate than in P. protesilaus and P. telesilaus, often slightly yellow ; the 

 marginal teeth R-, M' and M" longer, snbmarginal spots R- — M' pale yellow, paler
