Pilodeudorix, gen. nov. 



Allied to Bapala, Moore, from which it differs in the much 

 more triangular fore wings (the apex being more pointed 

 and the interior margin shorter), by the anal fold being much 

 more enlarged, and by having a long pencil of hairs attached 

 to the hind wing between the lower median nervule and the 

 submedian nervure near the base. The terminal joint of the 

 palpi is longer and stouter, and the antennas also are longer 

 and more gradually clavate. 



Type Pilodeudorix barbatus, mihi. 



The patch of hairs on the inner margin of fore wing and 

 the scaly patch on hind wing are both small. 



Pilodeudorix barbatus, sp. n. 



<$ . Upperside : fore wing jet-black, partially covered with 

 large ultramarine-blue scales, viz. from the base between the 

 costal and median nervure nearly to the apex, and from the 

 base beneath the lower median nervule to the interior angle, 

 leaving the outer half of the inner margin black ; a few blue 

 scales close to the outer margin between the median nervules. 



Hind wing jet-black, paler on the costal margin ; blue scales 

 in the cell ; a distinct, rather lighter blue streak from the 

 base to the outer margin, sharply bordered by the lower 

 median nervule and the submedian nervures. The anal fold 

 pure white from the base, merging into greyish above the 

 lobe which is very small and contains a dull red spot. A 

 very narrow black marginal line from the apex to the lobe. 

 The pencil of hairs which is attached to the wing near the 

 base being jet-black, about the length of the body, and falling 

 over the white anal fold. Cilia of fore wing black, of hind 

 wing silvery grey, more especially towards the anal angle ; a 

 short black linear tail, tipped with white, on the lower median 

 nervule. 



Underside rather dark greyish brown, with slightly darker 

 bands inwardly and outwardly edged with greyish white. 

 Fore wing : a short broad band at the end of the cell, and 

 beyond the middle, commencing below the costal margin, 

 a rather broader band, gradually tapering off towards the 

 inner margin, the lower half being placed closer to the base ; 

 a rather large black oblong band near the base just below the 

 median nervure, and below that a shining whitish space and 

 a small tuft of black hairs attached to the inner margin. 

 Hind wing with a short band about the middle of the cell, 

 and beyond that, commencing about the centre of the costal
