c? ? . Antenna black, scaling of upper.siJe lilack, usually fallen off. Black 

 Lairs of frons long. Tibiae ami tarsi pale green, scales preserved in fresh specimens 

 only ; inner tibial spnr longer than outer. 



Wings yellowish white. Forewing semitransparcnt ; four black bands, one 



across cell, stopping short in front of M-, a second on cross-veins, joined at lower 

 angle of cell to the third, which e.xtends from costal margin to hinder angle or close 

 to the angle, a fourth being marginal ; scales of yellowish white areas very narrow, 

 separate, sinuate, in posterior and basal areas alternately hair-shaped and triangnlar; 



on underside as above, but scales large and entire in posterior area of wing. 



Hindwing much denser scaled than forewing, scales entire in costal area, abdominal 

 and central areas from base to median band rather densely hairy ; black median 

 band thin, vestigial in front, slightly curved, touching apex of cell ; the band 

 complete on underside, centred with a more or less incomplete red line ; scales of 

 yellowish areas much narrower than on upperside, interspersed with fine hairs from 

 base to median band. 



The female larger than male ; wings broader, distal margin of forewing more 

 convex, red line of median band of hindwing vestigial on upperside ; the median 

 band more or less dilated in centre of wing on distal side, reminding one of P. salcini. 



Neuration : SC of forewing absent ; C ending farther distad tiian in other 

 species; PC of hindwing elbowed or nearly evenly curved; D^ of hindwing about 

 twice the length of D-, D' as long as or a little shorter than D'', angle of cell a little 

 less than 90°. 



Scent-organ : fold woolly, scales before and behind SM^' entire, large, some 

 scales of this kind also beneath the wool, whicli consists of thin long hairs, widest 

 in middle, and of longer and thicker stiff hairs vfcich end in an abrupt point. 



Genitalia : S . Tenth tergite long, compressed, trilobate at apex; dorso-ventral 

 ridge of harpe nearly continuous with dorsal edge of apical lobe, extending close to 

 the rounded apex of this lobe, ventral margin of harpe dentate, the harjie produced 

 proximally into a rounded lobe which reaches close to the ventral process, central 

 process strongly compressed, abruptly i^ointed. • ? not dissected. 



Early stages not known.

XV. Protesilaus Group. 



The species of this group resemble one another so closely in pattern that many 

 authors luxve treated them as mere individual varieties of one single species, with 

 the exception of J', ((ijesilaus, the distinctness of which the more recent authors at 

 least have not doubted. We have studied this group carefully, the result being 

 that we recognise no less than nine distinct species (as opposed to geographical and 

 individual forms). These species are distinguished in the genitalia, in jiattern and, 

 at least partly, also in the scent-organ of the hindwing. Five of these species occur 

 bide by side over the greater part of tropical South America, while the others have
