philolaus ; spot SC — SC* as in pkilolaus, white discal area about half as wide again 

 at RP as the bhxck distal area ; third black cell-baud extending a very little beyond 

 M, there being only a small black dot at the base of cellule M' — M' ; upper sub- 

 marginal spots larger than in philolaus, the posterior ones vestigial. Hiudwing 



narrower than in pkilolaus ; black median band stopping at cell, not reaching across 

 apex of cell as is the case in pkilolaus ; black distal area a little paler than in 

 pkilolaus, narrower, veins R^, R', and M' thinly black ; upper submarginal spot 

 vestigial, the others more or less washed with black. 



Underside : black bands somewhat paler than in pkilolaus. Forewing : last 



submarginal spot more or less vestigial ; black dot at base of cellule M' — M^ very 



small or absent. Hindwing : black snbbasal band narrower than in pkilolaus ; 



red line not undulate, crossing cell between M' and R^ or at M', the posterior 

 portion of the line more or less vestigial, 2 or 3 mm. distant from apex of cell ; the 

 line bordered with black distally and very feebly or not at all proximally ; two red 

 anal spots as in pkilolaus ; submarginal spots less distinct than in pkilolaus, 

 especially the upper ones. 



Neuration : cell of hindwing much less acute at apex than in pkilolaus, M' less 

 close to R^, and D" less oblique ; praecostal spur more proximal. 



Scent-organ : scales longer than in philolaus, the lateral filaments shorter. 



Genitalia similar to those of P. philolaus.

(J ? . Antenna black, beneath slightly tawny proximally ; scaling of upperside 

 black. Tibiae and tarsi pale green, not scaled, or only a very few scales present ; 

 mid- and hindtibial spurs as long as the tibia is broad, outer spnr a little shorter 

 than inner. 



Wings, upperside: scales nearly all entire, apart from tail and anal area. 

 Forewing : six greenish white bands and a row of submarginal spots, sixth band 

 short, reaching only to R' or R', being separate from the greenish white disciil ;ir(;i. 

 Hindwing : black median line marked only costally, sometimes vestigial. 



Red median line of underside of iiindwing reachirjg to blackish brown distal 

 band, contiguous with cross-veins D' and D-, there being no white spot in apex of 

 cell outside the red line or only a trace of such a spot ; the line bordered with black 

 on both sides costally, especially on the proximal side.
