33. NEOCHERITRA NISIBIS, n. sp., PI. P, Fig. 45, $ . 



Habitat : Kwala Lampur, Selangore, Malay Peninsula ; N.-E, 

 Sumatra. 



Expanse : 9 , 1*5 inches. 



Description : Female. Upperside, both wings dull hair-brown, 

 outwardly rather darker. Forewing unmarked. Cilia cinereous. 

 Hindwing with the anal third pure white, this white area reaching 

 from the abdominal margin (where it is widest) to just beyond the 

 third median nervule (where it is narrowest, dying away to nothing), 

 its inner edge irregular, arranged step -like, coincident with an outer 

 discal series of black spots on the underside ; this white area bears a 

 rounded deep black spot on the incision in the abdominal margin 

 anterior to the anal lobe ; a larger round similar spot in the submedian 

 interspace well removed from the outer margin ; an exactly similar 

 spot in the first median interspace close to the margin ; a narrow 

 black streak close to the margin in the second median interspace ; a 

 similar streak on the abdominal margin above the incision; an anteciliary 

 fine black thread from the anal black spot to the third median nervule. 

 Cilia pure white. Tails two, pure white, faintly at the base centred 

 with black ; the external one at the end of the first median nervule 

 short (3 mm. in length) ; the internal one at the end of the submedian 

 nervure rather long (9 mm. or '4 of an inch in length). Underside, 

 both wings rather dull orange". Forewing with the ground-colour 

 of the apical third becoming gradually darker towards the outer 

 margin ; the inner margin pale. Cilia dark grey, inwardly almost 

 fuscous. Hindwing with the costal third of the wing only dull orange, 

 gradually merging into the white colour of the rest of the surface ; 

 the three large spots towards the anal angle as on the upperside, also 

 the blackish streak on the abdominal margin ; the spot in the second 

 median interspace smaller, better defined, and of a deeper black ; 

 with two smaller rather indistinct spots in the two interspaces 

 beyond ; an outer discal series of four black spots, arranged nearly in 

 a straight line, the one nearest the abdominal margin shaped like a 

 very broad V, reaching from the internal nervure to the first median 

 nervule, the three others decreasing in size, somewhat reniform, the 

 anteciliary black thread of the upperside reaching almost to the apex
