Descriptions of new Butteufliks of the Indian Region : by 

 Arthur G. Butler, F.L.S., F.Z.S. 



Ixias insignis, u. sp. PL VIII, f. 1. 



Pale sulpliur-yellow, base of the wings broadly greenish-grey; 

 a very large, almost triangular, orange patch, from the centre of 

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

 by the first median branch, its outer margin oblique aliove the 

 loAver 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 lower disco- 

 cellular ; secondaries Avith a rather broad and slightly sinuated 

 external border ; wings below sulphur-yelloAV, irrorated with 

 brown ; secondaries with a squamose subcostal spot and three or 

 four across the disc. Expanse of wings 2 inches 7 lines. 



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



Nearest to /. balice, much larger, rather paler, and with a 

 considerably larger orange patch on the primaries ; base of 

 wings darker. 



Nephcronia lutescens, n, sp. 



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

 tiut^ with slightly narrower black external borders: on the under 

 surface the external border and apical area of primaries and the 

 Avhole ground-colour of secondaries suffused with butter-yellow; 

 veins dark brown as in A'. Valeria. Expanse of Avings 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, Mr. Moore having 

 found the species in a Collection which he was determining from 

 Tenasserim., was unable to discover that any description had been 

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

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

 description of the species, and it consequently got mislaid.
