this white area ending in the middle of the first median interspace. 

 Hindwing with the costa as far as the subcostal nervure and the second 

 subcostal nervule pale yellow, with two somewhat indistinct similar 

 streaks in the subcostal and discoidal interspaces ; the apex narrowly 

 pale yellow ; the abdominal margin broadly pale yellow ; the anal 

 lobe pale yellow, outwardly with a crescent of black scales ; a white 

 anteciliary line from the anal angle to just beyond the root of the 

 tail; tail black with a white tip. Cilia of the forewing from the 

 apex as far as the first median nervule white, with a prominent anteci- 

 liary black thread, posteriorly black ; of the hindwing pale yellow 

 at the apex, thence to the anal angle black. Underside, both wings 

 pale yellow. Forewing with the inner margin whitish centred with 

 fuscous ; a large prominent black spot crossing the middle of the 

 discoidal cell ; a similar wedge-shaped one at the middle of the costa ; 

 and a smaller round one in the second median interspace ; a prominent 

 anteciliary black thread ; the sexual tuft of hairs from the inner margin 

 near the base of the wing turned under and forwards rather small 

 and deep black. Hindwing with an elongated oval marking anterior 

 to the anal angle commencing from the internal nervure, consisting of 

 a pale yellow centre, bounded by a black line, and then an equally 

 broad bluish-white line, this ring-spot gives off outwardly a short black 

 line, which is posteriorly defined by a bluish-white line ; a marginal 

 black fascia, commencing very narrowly at the lower subcostal nervule, 

 increasing in width till it reaches the third median nervule ; in the 

 submedian interspace a little removed from the margin is a clump of 

 irrorated black scales ; the anal lobe is black, crowned with a clump of 

 pale silvery-greenish scales. Gilia of the forewing anteriorly whitish, 

 posteriorly black ; of the hindwing anteriorly as far as the lower sub- 

 costal nervule pale yellow, thence to the second median nervule black, 

 thence to the anal angle white tipped with black. Antennae black, but 

 the base of the club white. Frons and palpi pale yellow ; a pale yellow 

 line surrounding the eyes. Body above dark brown, beneath and legs 

 pale yellow. 



Mr. H. H. Druce has (1. c.) given a short description of this 

 species, but did not name it. It can at a glance be distinguished from 

 " Deudorix " domitia, Hewitson, from Malacca (Butler and Staudinger), 

 Singapore (Hewitson), Sumatra (Grose Smith), Kepras, N.-E. Sumatra 

 (de Niceville and Martin), and Billitou Island (Snellen), by the pale 

 yellow markings of both wings on the upperside, and by the apical 

 white patch on the forewing ; on the underside the ground-colour is 

 of a much paler shade of yellow. 



Described from a single example kindly given to me by Mr. E. F. 

 Skertchly, who captured it at Sandakan on the 10th May, 1888.
