414 COL. C. SWINHOE ON NEW [NoV. 5, 



close together ; and a broad blackish discal band, sinuous inwardly, 

 suffused outwardly towards the outer margin, and including a 

 sinuous whitish line, a black spot in the centre of the autemedial 

 line; orbicular represented by a black dot, reniform by a suffused 

 large blackish spot, outer margin with black points, fringe steel- 

 grey. 



Hind wings white, a broad black outer border, attenuated hind- 

 wards, and without the usual anal whitish streak in the band: 

 abdominal border suffused with grey, marginal line brown, marginal 

 points black, fringe pure white. 



Underside greyish white ; tarsi brown, with whitish bands ; wings 

 nearly white, with a broad blackish marginal band on each wing, 

 diffused outwardly to greyish on fore wings, and to pure white on 

 hind wings ; fringe and marginal points as above. 



Expanse of wings 2j2_ inches. 



Sab. Rangoon, June 1888. One pair of this fine species 

 received from Mr. Noble. 



This is a larger insect than P. quenavadi, the wings being com- 

 paratively longer; the fore wing has similarly disposed markings, 

 but these are more widely separated. The hind wing is less qua- 

 drate in form, the outer margin more rounded, and the marginal 

 black band is broader at its upper end. 



OpHIUSIDiE. 



Ophiusa triangulata, n. sp. (Plate XLIII. fig. 5.) 



Blackish brown, bands and lines white ; fore wings with a central 

 erect band slightly contracted in its centre, and irrorated with black 

 atoms ; from the lower extremity of this band on the hinder mar- 

 gin a thick line runs straight to the centre of the outer margin 

 (but does not touch it), and is angled from thence straight to the 

 costal margin, near to but a little apart from the central band, thus 

 forming a complete and very prominent triangle ; there is also a 

 fine sinuous submarginal line from the hinder margin to the apex 

 touching the elbow of the triangle ; the submarginal space is paler 

 coloured, and many of the veins are streaked with white, especially 

 so near the outer margin ; marginal festoon and points black ; cilia 

 grey, interlined. 



Hind wings with a white fascia slightly before the middle, a thin 

 white streak at the anal angle, and a thin white border ; marginal 

 line black ; cilia grey. 



Underside pale dirty greyish brown, with indistinct antemedial, 

 medial, and postmedial grey bands, a submarginal sinuous pale line ; 

 outer margin thinly pale greyish ; marginal festoon and points black ; 

 cilia grey. 



Expanse of wings ly^^ inch. 



Had. Karachi, July 1886. One perfect example taken. 



Nearly allied to Ophiusa mirabilis, Romanoff, Me'm. Lcp. ii. pi. 4.
