I believe that Mr. Walker was quite right in separating this species from P. satellitia 

 of Linnaeus (see Drury, pi. 29. fig. 1); the male of that species does not differ in size 

 or colouring, but slightly in form and pattern, from the female. P. pandoras is, in fact, 

 allied to P. licaon, Cramer (nee Hubner) more nearly than to P. satellitia ; it shows 

 also traces of affinity to P. achemon in the more angulated form of the line defining the 

 clouded discal area of primaries.

This appears to me to be a variety of P. pandorus.

Probably the male of P. satellitia, but so imperfectly described that it is impossible 

 to identify it with certainty. 



12. Philampelus lycaon.

This species is of a redder tint than P. satellitia ; the primaries exhibit more markedly 

 than in any of the other species the apparent division into a basi-internal light and an 

 apical dark area ; the hind wings have no rosy flush (as in Hiibner's species) at anal 

 angle of secondaries ; but they have on the underside an indistinct rusty reddish apical 

 spot on secondaries. The insect is, as Cramer says, " en dessous de coaleur minium et 

 vers les pointes des ailes inferieures de couleur roasse." Mr. Grote appears to have mis- 

 understood this description.
