Binsitta barvrowi, form. nov. 
g. Upper-side white with a shining silky gloss. Fore-wing with 
the following black markings :—a large square spot near the base of 
the costa, a larger rectangular patch just beyond, that extends trans- 
versely from the costa to the median vein, a border along the apical 
half of the costal margin, continued broadly from the apex of the 
wing along the anterior three-fourths of the termen and only slightly 
narrowed posteriorly ; at about two-thirds of the length of the wing 
from the base this black border is produced downwards in the form 
of an upper rounded discal patch. Looked at perpendicularly from 
above, the markings just described appear entirely black, but in a 
side light the scales, which are remarkably broad, densely packed and 
partially erect, take on beautiful metallic tints of blue and green of 
different shades and delicate lilac ; scattered over the medial area 
of the wing and along the edge of the apical half of the costa are 
curious erect little tufts of bright ferruginous scales. Hind-wing: 
apical third shaded with shining bronzy-brown that darkens out- 
wards and changes to metallic purple on the costal margin and apex 
of wing. Under-side white. Fore-wing: the black markings near 
base of wing somewhat as on the upper-side but more diffuse, no erect 
or semi-erect scaling; apical half of wing shaded with bronzy dark 
brown with a purple sheen in certain lights ; the dark shading con- 
tinued diffusely along the median vein towards the base. Hind- 
wing: apical third heavily shaded with metallic purplish-black scales. 
Cilia of the anterior two-thirds of the fore and of the anterior half 
of the hind-wing black with a metallic sheen, the rest white. An- 
tenn and the outer sides of the palpi near the base black, the front 
and inner side of the basal half of the palpi white, the apical half 
with tufts of bright ferruginous scales ; head, thorax and abdomen 
silky shining white, the apical segment of the latter black with a 
tuft of long white hairs ; beneath: the thorax and abdomen silky 
shining white, the latter with two rows of black spots on each side ; 
legs black with a few transverse white bars.
