314 RHOPALOCERA MALAY AN A. 



I feel no doubt as to the Tachjris alope, Wall., being the male sex of A. leis. I have 

 received all male examples of the tirst and female representatives only of the second, whilst 

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

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

 Museum, but this is evidently an error, as Mr. Butler has searched for me and can find no 

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

Ilyposcritia phinn, Moore, MS. 



Male. Wings above isearly-wbite ; anterior wings with tlie base bluish-grey, the base of costal area 

 dusted with dark greyish, the apical area broadly black, containing two small white subapical spots, and 

 inwardly much angulated, touching upper extremity of ceU, inwardly angulated between first and second 

 median uervules, 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 ochraceous tinge, the costal margin narrowly darker 

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

 body beneath and legs more or less 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 less distinct and more or less broken up 

 from the discoidal nervule 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, S , 50 millim. ; J , 58 millim. 



Hab.— Malay Peninsula; Province Wellesley (coll. Dist.) ; Perak (Kiinstler— Calc. Mus.) ; Malacca 

 (Pinwill— Brit. Mus.).— Sumatra (coll. Dist.).— Java (coll. Horsf.).— Borneo (Lowe— coll. Dist.). 



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

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

 only of a local varietal nature : — " Constantly differing from the Javan .1. 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 ; I the apex of primaries below and the 

 secondaries of a clearer cream-colour." §

I Mr. Butler writes, " We have two male A. alope fi-om Smuatra, and one of these is a httle more heavily marked than 

 tlie other, and may be the female of Wallace's description." 



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