These all appear to be rare insects in collections received from the Malay Peninsula, but 

 this is probably more apparent than real ; for from their somewhat general similarity an 

 uneutouiological collector would oftoo consider them on the wing as but one species, and 

 neglect them accordingly. 



10. Euthalia stoliczkana,* u. sp. (Tab. XIV., % LI ? .) 



Male. Closely resembling the male E. mtwnniri, but larger, and with the bluish marginal fasciae 

 on both wings above a little broader ; beneath with the narrow fuaooBB outer discal fasciae to both wings 

 much more waved and emulated. 



Female. Winga above closely resembling the female E. macnairi, but differing above by the absence 

 of the bluish marginal fascife, which are only slightly indicated near posterior angle of the anterior wings, 

 and appear on posterior wingB as a narrow diacal fascia, which becomes obsolete towards abdominal 

 margin ; on these wings the narrow fuscous discnl fasciae of the anterior wings are also continued, the 

 innermost distinct, the outer one not distinctly passing first median nervule. Wings beneath warmer in 

 hue than in E. numm.fi, and distinctly differentiated from that species by the waved and sinuated outer 

 discal fasciae to both wings.

11. Euthalia maclayi, f n. sp. (Tab. XIV., fig. 12 ? .) 



Male. Wings above almost identical with those of male E. macnairi ; beneath with the outer dkcal 

 fascia waved and sinuated as in E* itotksk&nat but on posterior wings the outer fascia is farther removed 

 from the margin than in that species. 



Female. Wings above closely resembling those of female E. macnairi, but the bluish marginal 

 fascia to posterior wings inwardly strongly waved and hollowed at the subcostal and discoidal nervuleB.I 

 Beneath the wings have the outer discal fascia strongly waved and sinuated as in E. stolkskuna, but on 

 anterior wiugs these fascia are wider apart than in that species, and on tin* posterior wings the outer 

 fascia is farther removed from the margin.

/•;. mamtdri) PL stoliczkana, and E. maclayi have so strong a superficial resemblance as to 

 give the impression that they are but varieties of one species, and this was my first conclusion. 

 The reasons which have impelled me to take the opposite view are that both sexes can he 

 differentiated, and that the forma are not intermediate. Thus, though E. madmji resembles
