Habitat : Chumbi Valley, Eastern Thibet. 



Expanse : c?, 2*2 inches. 



Description : Male. Upperside, both wings pure dend chalky- 

 wliite ; the base thickly sprinkled with black scales. Forewing with a 

 small black spot on the lower disco-cellular nervule ; the costa very 

 narrowly black ; the apex widely black, this black colour rapidly de- 

 creasing on the outer margin till at the termination of the first median 

 nervule it entirely dizn-p pears, the black colour extending narrowly 

 along the veins on to the disc of the wing ; a large round black spot 

 on the middle of the second median interspace bounded by the veins ; 

 posterior to this spot is a small clump of black scales. Hindwing with 

 the veins sometimes very narrowly black ; a large round apical black 

 spot placed between the subcostal nervules ; with sometimes three discal 

 small round black spots in the middle of each interspace posterior to 

 the subapical spot. Underside, forewing with the ground-colour pure 

 dead chalky-white ; all the veins narrowly black, the disco-cellular spot 

 larger than on the upperside, covering both the disco-cellular nervules \ 

 the apex and outer margin narrowly and decreasingly ochreous ; all the 

 veins black, that colour widening out on the veins as they reach the 

 outer margin ; the round black spot in the second median interspace 

 as on the upperside ; in continuation of which to the submedian ner- 

 vure is a narrow streak of powdery black scales. Hindwing with the 

 base of the costa rich chrome-yellow ; the rest of the wing ochreous j 

 all the veins broadly defined with black ; with a powdery rather indis- 

 tinct curved discal black band, the bifurcated streak in the submedian 

 interspace as far as the discal band only rich chrome-yellow. Cilia 

 throughout white. Female unknown. 



Differs from the same sex of Pieris dubernardi, Oberthiir,t (to judge 

 from his figure only, I have not seen a specimen) on the upperside of the 

 forewing in the costa being less black, there is a line of the white ground- 



* The genus Parapieris I propose for Papilio callidice, Esper (the type), and its 

 allies. A full description of it will appear in vol. iv of " The Butterflies of India, 

 Burmah and Ceylon " by myself. P. chumbiensis doubtf ally belongs to the genua 

 Parapieris, but I do not know any described genus in which it could be more appro- 

 priately placed.
