RHOPA LO CERA MALAY AN A. 



I feel no doubt as to the Taclujris alopc, Wall., being the male sex of A. lets. I have 

 received ail male examples of the first and female representatives only of the second, whilst 

 examination of the specimens in tho British Museum and in the line collection of Mr. F. Moore, 

 show the same facts. Mr. Wallace* refers to a Snmatrau female of A. atope in the British 

 Museum, but this is evidently an error, as Mi*. Butler has searched for me and can lind no 

 such specimen, t the probability being that the female of some other species was substituted.

Male. Wings above pearly -wb ite ; ant trior wins* with lli- i :im Muish-grey, the base of costal area 

 dusted with dark greyish, the apical urea, broadly black, containing two .small white subapieal spota, and 

 inwardly much an^ulated, touching upper extremity of cell, inwardly angulated between llrat and second 

 median nervules, and narrowest and terminating a little above outer angle ; posterior wings with a slight 

 black marginal spot at apex. Anterior wings beneath with the black apical area as above, but with the 

 apex broadly brownish- grey ; posterior wings with an ochraccous tiu^e, the costal margin narrowly darker 

 ochraceous. Body above with thu pronotum clothed with long pale greenish hairs, the abdomen infuseated ; 

 body beneath and legs more or leas concolorous with wings, legs streaked with fuscous. 



Female. Wings above resembling the male, but with the black apical area of the anterior wings 

 larger and with a black margin to the posterior wings, which is lees distinct and more or less broken up 

 from the discoidat nermle to anal angle. Wings beneath as in male, the posterior wings having sometimes 

 a roseate tinge, and sometimes indications of an obscure, waved and broken fuscous submarginal fascia. 



Exp, wings, 3 , 50 millim. \ 2 , 58 milbiu.

 (Pinwiil — Brit. Mus.). — Sumatra (coJl. Dist,). — Java (coll, Horsf,). — Borneo (Lowe — coll. Dist.). 



Mr. Butler separated his species on the following characters of a male specimen, the 

 colour ones of whieb, though slight, appear to be quite constant, but are considered here as 

 only of a local varietal nature : — " Constantly differing from the Javan A . leptis of Felder in the 

 absence of the black border of secondaries, a trace only of which exists at the apex of these 

 wings ; also larger, the primaries more produced ; \ the apex of primaries below and the 

 secondaries of a clearer ere ain- colour." §

f Mr. ButW writes, " Wo. htive two male A. alopc Iroin Sumatra, and one of these i& a little more heavily marked than 

 the other, and may bo tho female of Wallace's description." 



I This difference of aisie is not observable in the specimens before me.
