 Aktiiuu G. BuTLEi!, F.L.S., F.Z.8. 



Ixias insi(jnis, n. sp. PI. VIII, f. 1. 



Pale sulpliiir-yellow, Ixise of the wings Ijrocadly greeuish-grey ; 

 a very large, almost triaugular, orange ])atcli, from the centre of 

 the cell to the centre of the disc, crossed by black veins, limited 

 by the first median branch, its oiiter margin oblique aljove the 

 lower or true radial, and zigzag below it ; apical area, outer 

 border, and the inner half of the interno-median area, dark 

 chocolate-brown ; a pale centred black spot on the loAver disco- 

 cellular ; secondaries Avith a rather broad and slightly siuuatcd 

 external border ; wings below sulphur-yelloAV, irrorated with 

 brown ; secondaries with a squamosa subcostal spot and three or

Tai-wan-foo, Formosa (Rev. W. Campbell). 



Nearest to /. balicc, much larger, rather paler, and Avith a 

 considerably larger orange patcli on the primaries ; base of 

 Aviugs darker. 



Nepheronia lutescens, u. sp. 



$ Allied to N. Valeria but larger; above rather greener in 

 tint, with slightly narrower black external borders: on the under 

 sm-face the external border and apical area of primaries and the 

 whole ground-colour of secondaries suffused with Inittcr-yellow; 

 veins dark brown as in X. Valeria. Expanse of wings 3 inches 

 5 lines. 



Borneo (Low). 



I labelled this species with the above name some years since, 

 but by some oversight omitted to describe it, INIr. Moore having 

 found tlie species in a Collection which he was determining from 

 Tenasscrim, was vniable to discover that any description had hccn 

 published and called my attention to the fact. I can only 

 account for this by the supposition that I wrote out an isolated 

 •lescrijition of the species, and it consecjuently got mislaid.
