9. Sephisa rex, sp. nov. 



Two specimens of this species, male and female, v/ere taken by Mr. 

 Kikuchi at Lake Suisha in November, 1907, and were purchased from 

 him by Dr. Moltrecht and are now in Dr. Moltrecht's collection. The 

 male somewhat resembles, in colour and in the pattern of the hindvvings, 

 the male of Sephisa princeps, Fixsen, (Rom. sur Lép. iii, p. 28g, pl. xiii, 

 figs. 7 a, b, 1887,) but is very dissimilar as regards pattern of fore wings. 

 Apatura cauta, Leech, (Proc. Zool. Soc. Lond,p. 417, pi. xxxv, fig. 2, J 1 ,) 

 is considered by Leech to be a synonym of 5. princeps, Fixsen, (Butt. 

 China, Japan, Corea, p 151, 1892-93,). The female of vS". rex is also very 

 different in pattern and colour to the female of S. princeps figured by 

 Leech (I.e. pi. xiv, fig. 5 £, 6 -£ var). These two specimens of S. rex. 

 may possibly be referable to either Sephisa dichroa, Kollar, or to 6". 

 chandra, Moore, both Himalayan species, which Leech mentions as being 

 allied to S. princeps, but I am unable to refer to the works in which these 

 two species are described and therefore cannot make any comparison. 



Male. Palpi white beneath, black above and at tips ; a straight white 

 streak beneath palpi ; base of thorax, ventral and lateral area of abdomen 

 spotted with white ; femora of forelegs edged with white externally ; 

 antennae black. Ground colour of all wings black sprinkled with a few 

 minute purple scales ; basal black area of forewing bounded by an oblique 

 band of four, large, fulvous spots incurved at the third spot towards inner 

 margin ; first spot near centre of cell, straight inner edge, indented outer 

 edge ; a discal, oblique series of five, large, white spots ; first three rather 

 close together with apices pointing outwards, first at end of and above
