EHOPALOCEllA MALA VAX A. 123 



and two near extremity, which are continued and joined above the discoidal nerviile ; an anRulated hne 

 between the bases of the second and third median nervules ; an ovate spot between the bases of the lower 

 and upper subcostal nervules, preceded by a larger one situate beneath the costal nervure ; 1)otli wings 

 crossed by two submarginal waved fuscous lines, the outer one very dark on anterior wings, the apical 

 angle of which is suffused with greenish. Body and legs more or less coneolorous with wings. 



Exp. wings, 48 millim. 



Had. — Malay Peninsula ; Perak (Dr. Townsend— coll. Godm. & Salv.) ; Malacca (coll. Ilewits. and 

 coll. Pvoberts). 



The female of this species is either unknowu or unrecognised at present. The male here 

 figured is the specimen collected in Perak by Dr. Townsend, and now in the collection of 

 Messrs. Godman and Salvin, to whom I am much indebted for the facilities aiforded me 

 for examination and study.

9. Euthalia macnairi,* n. sp. (Tab. XIV., fig. C <? , 10 ? .) 



Male. Wings above very dark ehocolate-brown, the outer margins of lioth wings pale bluish ; on 

 anterior wings this bluish margin is narrow, commencing a little beneath apical angle, and slightly 

 widening and terminating at posterior angle : on posterior wings it is very broad, especially near anal 

 angle ; outer margins narrowly black, the fringe pearly white ; cell of anterior wings crossed by four 

 blackish lines, the innermost two nearly straight, the outer two prominently bent and sinuated, and 

 a similarly bent black line at end of cell ; the three innermost of these lines are continued beneath the 

 median nervure. Wings lieneath pale olivaceous-l)rown ; anterior wings with the basal area palest, 

 cellular markings as above, but more distinct, and two discal, narrow, undulating fuscous fascise, the inner 

 one waved, the outer entire, but somewhat discontinuous. Posterior wings with the cell crossed by some 

 indistinct fuscous lines, a similar convex one near its apex, and an elongate ovate spot on each side of the 

 base of the upper subcostal nervule ; two discal and parallel narrow fuscous fasciae, terminating at aboi;t 

 the third median nervule, the inner one broadest, and the outer narrow and somewhat broken. Body and 

 legs more or less coneolorous with wings. 



Female. Larger and paler in hue than the male : markings similar, l)ut anterior wings above 

 exhibiting the discal fascife only seen on the under surface of the male ; these fasciae are also slightly 

 broader and the colour between them somewhat paler ; cell of posterior wings exhibiting the transverse 

 dark linos as beneath. Wings beneath brighter and warmer in hue than in the other sex ; the markings 

 similar. 



Exp. wings, <? 55 millim. ; 2 70 millim. 



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



This and the following species represent a section of the genus in which the males are 

 strikingly similar to each other and equally dissimilar from the females. Felder appears to 

 have been first in recognising the sexual connection between these diverse forms, when he 

 described t the male of E. puseda. 



The great interest attaching to this species is that it represents the closest alliance and 

 resemblance between the sexes of this section, the following species here described and figured 

 showing a gradually increasing tendency to sexually differentiate ; whilst it is to the Indo- 

 Malayan region that this portion of the genus is almost confined.
