rarely vestigial ; tlie number of white discal patches ou npperside variable from 

 one to seven, the first always large, often occupying half the cellnle C — S(;-, but 

 never extending to base as in P. crassus, the others smaller and usually more 

 greenish, very variable in size, the scales composing them lying on top of the 

 metallic scales (as in P. lycidas), less acuminate than in /-". lycidas ; SC'^ ou the 

 whole branching off from cell a little more proximally than in P. lycidas. 



?. Dichromatic; the ordinary form similar to the male except in the abdomen 

 being metallic green above and the forewing bearing often some submarginal spots 

 on uj)perside ; the rarer form bearing a large huffish yellow patch on forewing 

 occupying apex of cell and the adjacent portions of the disc. 



Scent-organ : scales geographically variable, very close together, erect, either 

 about four times as long as broad, slightly curved, obtuse at apex and faintly or not 

 at all denticulate, somewhat cucumber-shaped, but compressed, though not ijuite 

 flat as ordinary scales ; or even shorter than in P. lycidas ; or of intermediate size. 



Genitalia : 3 • Harpe small, short, triangular, with the apex strongly rounded ; 

 ventral margin dilated into an acuminate lobe which stands vertically on the plane 



of the harpe ; tliis lobe cnrved basail, denticulate at distal edge. ?. Hairy lobes 



of vaginal cavity larger than in P. lycidas and the postvagiiial tubercle higher. 



Early stages not known. 



IJab. Mexico to Bolivia, eastwards to Parii ; not in Brazil ])roper, but may be 

 expected to occur in the province of Goyaz. 



Five subspecies. 



If the figure of P. niimitor Cram., I.e., does not represent a specimen of 

 P. lycidas, it represents a specimen of P. belus belus with spots on the disc of the 

 hindwing. There is no white streak on the hindwing of the figure, as there is 

 in P. lycidas, but the artist may have forgotten to put that streak in. 



a. P. belus chalccus subspec. nov. 



c?. Wings, npperside: hindwing deeper green at distal margin than on disc; 

 within this marginal area a row of angle-shaped submarginal spots of the same 

 green colour as the disc ; discal row of creamy white spots similar in position to 

 that of the Bolivian form, P. belus cochabamba, the row being straight or only 

 faintly curved from SC- to abdominal margin, spots from U' backwards small, spot 

 R' — R- farther away from cell than spot R- — R'. 



Underside, forewing: white fringe-spots as distinct as above. Hindwing: 



red submarginal bar C — SO- sharply marked (absent from the other forms or 

 vestigial) ; white admarginal dots very distinct. 



? not known. 



Scent-organ : scales very short, being partly broader than long, cuj)-shaped, 

 j)roximally strongly rounded, striatiun heavy, the apical edge appearing multidentate.
