(?. Head, thorax, and abdomen on the upperside grey, the abdomen black on 

 the sides with white segmental streaks. There are a few rufous hairs on the first 

 segment near the insertion of the hindwing. The underside of the abdomen is 

 white with a series of triangular black spots marking the anterior segments. The 

 forewings are dark grey, banded by basal, subbasal, and median curved blackish lines, 

 and marked with a similarly coloured spot on the outer margin and at the apex, 

 There is a distinct circular white spot at the end of the cell. The hindwing is pale 

 grey, somewhat clouded on the inner margin by obscure black lines. There is a 

 whitish grey triangular mark at the anal angle. The fringes of both wings are 

 black, checkered with white. On the underside the wings are grey, slightly paler 

 toward the base. The hindwing is crossed by an obscure dark median line parallel 

 to the outer border. The antennae are white, with the setae dark brown.

(J. The palpi on the upperside, the collar, and the anterior portion of the thorax 

 are dull olive green, shading on the posterior portion of the thorax into deep black. 

 The upperside of the abdomen is deep black, the segments being lightly marked on 

 the anterior edge with white. The palpi on the underside and the pectus as well as 

 the anterior pair of legs are pure white. The abdomen on the underside is black 

 with lateral tufts of black hair tipped with snow white. There are a few minute 

 white spots on the median line of the abdomen on the underside. There are two 

 tufts of coal black hairs at the end of the abdomen. The anterior wings on the upper- 

 side are violet brown crossed by a basal, median, and postmedian band of dark brown, 

 the latter band invaded and interrupted in the region of the median nervules and at 

 the apex by patches of the prevalent ground colour. The hindwing is jet black, on 

 the anterior margin pale purplish brown. On the underside both wings are smoky 

 except at the base, where they are pure white. 



Expanse : 53 mm. 



This distinctly marked species is represented by a single .specimen which does 

 not agree with the description of any species known to me, and is not represented, 

 so far as I am aware, in any other collection. Sir George Hamjison informs me that 

 it is not contained in the British Museum, and is entirely unknown to him.
