124 RUOPALOCEIIA MALAY AN A. 



These all iii)pear to bo rjire insects iu collections received from the Malay Peninsula, but 

 this is i)rol)al)ly more apparent than real ; for from their somewhat general similarity an 

 unentomological collector would often consider them on the wing as but one species, and 

 neglect them accordingly. 



10. Euthalia stoliczkana,* n. sp. (Tab. XIV., lig. 11 2.) 



Male. Closely resembling the male E. iii<(ciiitiri, but larger, and with the bluish marginal fascise 

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

 much more waved and sinuated. 



Female. Wings above closely resembling the female E. Dtucmiiri, but differing above by the absence 

 of the bluish marginal fasciie, which are only sligiitly indicated near posterior angle of the anterior wings, 

 and appear on posterior wings as a narrow discal fascia, which becomes obsolete towards abdominal 

 margin ; on these wings the narrow fuscous discal fascia) 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. niacnairi, and distinctly differentiated from that species by the waved and sinuated outer 

 discal fasciae to both wings. 



Exp. wings, (? 62 millim. ; ? 70 millim. 



Hab. — Malay Peninsula ; Province Wellesley (coll. Dist.) 



11. Euthalia maclayi,t n. sp. (Tab. XIV., fig. 12 5 .) 



Male. Wings above almost identical with those of male E. inacnairi ,- beneath with the outer discal 

 fascia waved and sinuated as in E. stoliczkana, but on i)Osterior wings the outer fascia is farther removed 

 from the margin than in that species. 



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

 fascia to posterior wings inwardly strongly waved and hollowed at the subcostal and discoidal uervules.J 

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

 anterior wings these fascia; are wider apart than iu that species, and on the posterior wings the outer 

 fascia is farther removed from the margin. 



Exp. wings, <? (one spec.) Gl millim. ; ? 73 millim. 



Hab. — Malay Peninsula ; Province Wellesley (coll. Dist.) 



E. macnairi, E. sloliczkaiia, 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 be 

 differentiated, and that the forms are not intermediate. Thus, though E. madaiji resembles 



* This species is dedicated to the late Dr. Ferdinand Stoliczka, the accomplished and versatile naturalist, who died 

 a few years since whilst accompanying the Second Yarkand Mission. He visited the Straits Settlements, and his enthusiasm 

 there in the cause of Zoology and scientific industry is shown by the following papers, viz. : —

 f In agreement with the principle I have pursued in this work, of using for specific purposes the names of those who 

 have worked or are working at tlie biology, ethnology, or natural features of the Malay Peninsula, I have here used the 

 name of the celebrated Kussian ethnologist and traveller Dr. Mikluho-Maclay, who a few years since made an ethnological 

 excursion in Johore.

 m a rubbed and poor condition.
