Male. Wings above creamy-white ; anterior wings with the costal area bluish-grey, the apex and 

 outer margin broadly blackish, and containing three white spots — two separated by the fifth median 

 uervule and one between the first and second median nervules ; posterior wings with the outer margin 

 somewhat broadly blackish, the dark coloration extending inwardly and ray-like a short distance along the 

 neuration. Anterior wings beneath as above, but the dark area much paler and more broken up with 

 whitish ; posterior wings with the neuration blackish, a broad blackish marginal fascia, most distinct 

 at anal angle, and from thence to apex broken and indistinct, basal and abdominal area ochraceous, this 

 hue not extending beyond the cell. Body above more or less concolorous with wings ; abdomen beneath 

 creamy-white ; thorax and legs greyish-white, the last streaked with fuscous. 



Exp. wings, (? , 70 millim. 



Hab. — Malay Peninsula : Perak (Kiinstler — Calc. Mus.) ; Malacca (coll. Wall.).- Sumatra (coll. Wall.) ; 

 Padang (Vollenhoven). — Borneo (coll. Hewits.) ; Sarawak (Brit. Mus.). 



In his paper on the 'Eastern Pieridae,' Mr. Wallace observes, in relation to this species, 

 " my specimens are intermediate between Hewitson's and Vollenhoven 's figures, and I have no 

 doul)t but that they represent one rather variable species."* This remark exactly applies to 

 the Perak specimen here figured, for an examination of which I am indebted to Dr. Anderson. 



Genus SALETARA. 



Saletara, Distant, antea, p. 287. 



This genus is closely allied to Ajijiins, and is separated on the structural characters of the subcostal 

 nervules of the anterior wings, which, as in S. nathalvi, Feld., number five in the male and four in 

 the female, or, as in N. pnmht, Godt., I number only four in each sex. This variation exists in the third and 

 fourth subcostal nervules, which when present in the male bifurcate close to the apex of the anterior 

 wing. 



This is a genus in which we can almost see the characters in course of consolidation. 

 Not only is there the difference already pointed out between the subcostal nervules in 

 S. t}atludia and .S'. panda, but in a specimen of the first-named species in my own collection, 

 one wing possesses the third and fourth subcostal nervules and the other wing only one of 

 them, as in the female, and as in both sexes of N. panda. 



Sah'tara is a genus of small extent, and is apparently confined to the Malay Peninsula 

 and some of the islands of the Malayan Archipelago.
