fasciae, anterior vertical, blackish-edged posteriorly, posterior slightly oblique, 

 blackish -edged anteriorly ; a very short white dash midway between band 

 und apex ; a small white spot in apical cilia, marked also on undersurface : 

 cilia blackish, with a white costal spot on posterior fascia. Hindwings and 

 cilia dark fuscous. 



Khasis, in November ; two specimens. Characterised by the absence of the 

 usual white apical band of antennae, black admixture of the orange band, entire 

 posterior metallic fascia, and very short basal streaks. 



Cosniopteryx holophracta, n. sp, 



$ $. 10-11 mm. Head dark bronze, with a white line above each eye, 

 face silvery. Palpi white lined with blackish. Antennas black, dotted and lined 

 with white, three apical joints white, then five black, one white, one black, 

 one white. Thorax dark bronze, with three fine white lines. Abdomen dark 

 fuscous. Posterior tibiae black with white median and apical rings, and a 

 silvery ring between these. Forewings very narrowly lanceolate, apex slenderly 

 long-produced, caudate ; blackish ; dorsal edge sHvery- white towards base ; 

 a short fine silvery subcostal dash about i ; a very fine silvery-white median 

 line from base to about ^ ; a short fine silvery-white dash beneath posterior 

 portion of this ; a broad orange postmedian transverse band, edged anteriorly 

 by a vertical violet- golden-metallic fascia black-edged posteriorly, and poste- 

 riorly by a rather oblique violet-golden-metallic fascia black-edged anteriorly : 

 a pale violet-golden-metallic streak extending from before middle of apical 

 area to apex ; a small white spot in apical cilia, marked also on undersurface : 

 cilia blackish-grey, with a costal white spot on posterior fascia. Hindwings 

 and cilia dark fuscous. 



Khasis, in May and August ; two specimens. Distinguished from all the 

 orange-banded species of the region by the combination of white arex of

 Posterior tibiae black with white median and apical rings, and a silvery ring 

 between these. Forewings very narrowly lanceolate, apex slenderly long- 

 produced, caudate ; blackish ; dorsal edge silvery-white towards base ; three 

 fine white lines on basal area, subcostal from base to i, rather oblique, median 

 from base to ^, subdorsal rather shorter than half median, ending equally 

 with it ; a broad orange postmedian transverse band, margined anteriorly by u 

 vertical violet-golden-metallic fascia followed above middle by ablack dot, and 

 posteriorly by an oblique violet-golden-metallic fascia preceded by a few black 

 scales and interrupted above middle by a short linear orange projection ; a very 

 short white dash midway between band and apex ; a white dash in apical cilia.
