DESCRIPTIONS OP NEW SPECIES OF DIURNAL LEPIDOPTEBA. 

 BY ARTHUR GARDINER BUTLER, E.L.S. 



Genus AMATHUSIA. 



1. — Amathusia Ottomana, sp. nov. 



Alee supra fuscce, anticce fascia disco-costali violaced ; posticce caudd 

 ocellatd : subtus roseo-f usees, striis septem anticis,sexque posticis diver gen- 

 tibus, brunneis, ocelli's duobus posticis permagnis,fusco-ockraceis. 



Allied to Amythaon, but differs entirely in regard to the shape and 

 position of the violet band of the front-wings, which begins on the 

 costa, close to the base, continues beyond the end of the cell, then 

 slopes obliquely towards but not reaching the outer margin, from 

 which it turns off, tapering to just below the first median nervule ; 

 each wing being thus ornamented with a large violet crescent. The 

 hind-wings are shot with violet. The under-surface of the wings is 

 nearly the same as in A. Amythaon, but of a more pinky hue and with 

 larger ocelli. 



Inhabits Borneo (Sarawak, Lowe). 



In the collection of Herbert Druce, Esq. 



This does not agree with the descriptions of Felder's A. Pylaon 

 or Porihaon from Java, his Indian species being probably the true £ 

 Amythaon of Doubleday (but not of Westwood.) The figure in the 

 " Oriental Entomology," represents a species with a much narrower 

 and duller violet band on the front-wings, leaving a large brown space at 

 the apex ; the brushes on either side of the body seem also to be un- 

 usually developed. There can be little doubt that this is a distinct 

 species, for which I propose the name of A. Westwoodii. 



The type of the figure is said to be in the collection of H. G-. 

 Harrington, Esq. 



I hope soon to be able to figure A. Ottomana, and the other species 

 here described. 



Genus PAPILIO. 



1. — Papilio Kerosa, sp. nov. 



<$ P. Paradoxes affinis, Euplceam Amymonem simulat. Alee supra 

 fuscce, anticce obscuriores, purpurascentes, punctis arece apicalis pallidiori- 

 bus : subtus fuscce, punctis septem anticis, sex posticis, sub-marginalibus, 

 albis : corpus nigro-fuscum, albo-punctatum. 



Wings above : brown, darker towards the base, the front- wings
