the 2. submeilian vein, the B. band 2 to 3 nun distant tVom the lower angle of the cell, not nanoweil before 

 the '2. radial, the transparent submarginal band at least twice as broad at the 5. subcostal as the black 

 marginal band. Panama: Colombia, with the exception of the province of Tlauca, ])erhaps also in North 

 Venezuela. - melaenus //. d- J. The black bands broader than in the preceding form, the transparent melaemix. 

 submarginal interspace of the forewing usually onlj' little or not at all broader at the 5. subcostal than the 

 marginal band, in some specimens, however, much broader, in which case the interspace between bands 5 

 and 6 is narrowed correspondingly. West Colombia and upper Cauca Valley. — ieucas A', d- .1. Wings only U-ucas. 

 distinctly green towards the base; ]iostdiscal band of the forewing narrowed near the lower angle of the 

 cell and usually before the 2. radial. Hindwing more obtusely dentate than in jyi-otesilaics, the sulimarginal 

 spots tinged with brown, 2. band of the forewing from the cell backwards narrower above than beneath, the 

 side of the frons white. The harpe of leucan more obtuse than in rilniirolina^, the dorsal tooth narrower and the 

 central process longer. Orinoco, Guiana, the Amazons, Ea.st Ecuador. East Peru and Matto Grosso; common. 



P. molops. The 1. and 2. black band of the foi'ewing broad and both or at least one of them 

 extending to the hindmargin, the 4. band usually leaching ([uite across the cell. The denticulate, deflexed 

 dorsal margin of the harpe rounded-dilated. ? unknown. Trojiical South America, widely distributed, but 

 only singl\- among the white buttertlies of this grouj). — molops IL d- J. Antenna bi'ownish yellow: the molops. 

 black lateral stripe of the abdomen as broad as the yellow-white stripe placed at its dorsal side; 1. and 2. 

 band of the forewing broad, the 1. not extending to the hindmargin, the other bands likewise broad, the 

 G. especially is broader than in all the other forms of the 7)ro/r.s-//(//^s--group, being at least as broad as the 

 interspace between bands 5 and 6; this fi. band close to the lower angle of the cell. Dorsal margin of the 

 harpe abruptly dilated. North-West Ecuador and West Golondiia. — hetaerius R. (t ./. (15 b). Easy to hetaeiius. 

 differentiate from the preceding form by the thinner black bands; it is so similar to the ■protcxihtus forms 

 occuiTing together with lirfacriKs as to be easily mistaken for them, but is much smaller than the Colombian 

 /iroti'si/aiis and has a much less sharply dentate hindwing. Sides of the frons always white; 1. and 2. band 

 of the forewing extending to the hindmargin. or the 2. band very little abbreviated; the wiiite submarginal 

 lunule between the 1. and 2. radial of the hindwing narrower than the corresponding marginal lunule; the 

 interspace between the subbasal and median band on the under surface of the hindwing longer than in 

 priiti'nilaiiii. Harpe somewliat ditferent from the harpe of inolups, dorsal and ventral edges more denticulate, 

 the ventral process longer and curved towards the Aentral edge of the clasper. Guiana, Amazons, Colombia, 

 Ecuador (except the western side), Peru and Bolivia. — megalurus //. tf J. Antenna black as in the meaalnnis. 

 Brazilian proft'si/'uis; frons lateral!}- white: the white subdorsal line of the abdomen thin: 1. and 2. band of 

 the forewing extend to the hindmargin, B. band separated from the angle of the cell; the black markings 

 of the hindwing somewhat more developed than in hcturriiig, the red anal spot longer: tail long and Jiroad. 

 Dorsal edge of the harpe less dilated than in the other forms of ino/op.'i. Brazil: Leopoldina, but probably 

 more widely distributed. 



P. protesilaus. Submarginal spots of the hindwing white, rarely slightly yellowish, hindwing more 

 strongly dentate than in </laiiC(i/aiis, the 1. and 2. band of the forewing on the whole shorter than in iiwlops. 

 Frons sometimes entirely brown-black. The scent-scales very long and thin. The dorsal edge of the harpe 

 detlexed, lying flat on the harpe, strongly dentate. Larva not known. Mexico to South Brazil. — penthe- pi'iithc^ilaus 

 silaus Fldr. Large; dorsal streak of the abdomen very narrow; 1. band of the forewing extending to the 

 2. submedian vein, 2. band a little beyond it: 4. band short, triangular, rarely reaching to the 2. cell-fold: 

 tj. band separate from the angle of the cell, somewhat narrowed before the 2. radial, jiosteriorly almost 

 always separated from the marginal band; red anal spot of the hindwing large, marginal teeth partly 

 strongly projecting, fringes white except a the extremities of the veins. Apex of the harpe pointed, dorsal 

 edge rounded. Mexico, the only form of this group which occurs so far north; it is found in Vera Cruz, 

 Yucatan, Atoyac. Oaxaca etc., in wooded districts, and in the South intergrades completely with the next 

 form. — macrosilaus (h-mj from Guatemala, British Honduras, Honduras and Nicaragua. 1. and 2. bands wncrosiiiuis. 

 of the forewing narrow, the 4. is absent or is only represented by a costal spot, the 6. somewhat angled 

 at the 2. radial and narrowed costad, posteriorly connected with the marginal band; the latter less sharply 

 defined and somewhat paler than in pinflif^ihiiis, transparent, submarginal liand with hairy scales; red anal 

 spot of the hindwing narrower than in pcnilirsilfmx. Apex of the harpe truncate, central process shorter 

 than in the Mexican form, spatulate. strongly dentate at the apex, ventral process not extending to the 

 clasper, curved backwards. — leucones B. d ■/. Black dorsal line of the abdomen absent or thin; 1. band li'iiconrs. 

 of the forewing thin, 2. extending to the hindmargin or nearly to it, the interspaces between 1. and 3. of 

 equal breadth at the median vein; the white marginal and sulimarginal spots of the hindwing large, the margin 

 only black at the extreme tips of the veins, but the fringes from the costa to the 2. radial partly black; 

 red anal spot large. Harpe similar to that of iimcrosildiin, some of the teeth of the ventral edge enlarged, 

 ventral process non-dentate, not extending to the lower edge of the clasper, the teeth of the spatulate 

 central process more or less curved dorsal. Manaure, at the foot of the Santa Marta in North Colombia; 

 probably this form inhabits the north coast of Colombia. — dariensis //. d J. Dorsal line of the alnlomen dariensis.
