the nervuies. The size iind form of the white markings in the outer region of tlie 

 hindwings is very variable. 



J. The posterior part of the hastate mark divided by the lower discoidal nervule 

 of the forevrings above is often green instead of white. The underside exhibits some 

 variation, especially in the size of the white markings; those of the hindwings are 

 joined to one another, or widely se)iarated. The 5 from the Xatuna Islands stands 

 just intermediate between the typical form and T. hrool'innus (ilhescens mihi, having 

 the white markings of the underside larger than they are in bruokidiius, and smaller 

 than in albescens.

 marked as I he male; the white subapical markings of the u-ual form of the feiwde 

 are absent. Locality unknown.

i. Not distinguishable from typical ^rtici/LjV'uits, though on au average the white 

 spots on the undereide of the forewings seem to lie larger. 



5. Upperside: the subapical white markings of the forewings larger than in T. 

 brookianus, much less suffused with blackish brown, being pm-e white in the middle; 

 the submarginal spots to the hindwings are longer, extending from near the outer 

 margin more than half-way to the cell. 



Underside : the submarginal white markings of the forewings are broad and touch 

 one another, not being widely separated at the internervular folds. On the hind- 

 wings the white submarginal area is much more extended than in brookianus, forming 

 •A broad white band, which is traversed by rather thinly black nervules and includes 

 a black rounded spot within each cellule; these spots are sometinie.s connected with 

 the black disc of the wing by means of an interuervidar black streak; in brookianus 

 $ the disca^portion of the white band is obliterated, except at the veins.

The differences between T. trojanus and 1'. brookianus are so considerable, and 

 apparently so constant, that I must treat trojanus as a distinct speoie.s. It is, how- 

 ever, not impossible that further investigations in Palawan, which may enable us to 

 compare a larger series of specimens, will prove that at least the females of both 

 species run into one another. 



(S. The blue-green markings of the upperside of the forewings are short and 

 widely separated. The hindwings have a rather narrow, greenish blue, discal band above. 



?. Upperside: in the amount of white on both .-iides of the b.iewings it comes 

 nearest to '/'. brookianus albescens : above there are three gn'i-ti h^istiitc p:itclifs,
