1892.] L. de Niceville — Subgenus Stictoplcea of the genus Euploca. 161 



Habitat : Sikkim, Bhutan, Assam, Burma, Malay Peninsula, 

 Cochin- China. 



Expanse : cf, 2-8 to 42 ; ? , 3'4 to 4'2 inches. 



Description: Male. Upperside, forewing glossed with magni- 

 ficent blue throughout ; two prominent black impressed elongated 

 sexual brands in the submedian interspace placed one above the other, 

 the anterior rather the shorter ; marginal blue dots varying from none 

 to nine, when present invariably commencing at the anal an°-le and 

 never reaching the apex of the wing ; a submarginal series of larger 

 spots varying from five to eight, and shewing great variation in 

 size ; an angulated series of discal spots placed beyond the discoidal 

 cell, varying from none to five, also veiy variable in size ; a spot at 

 the outer posterior end of the cell and another on the costa between the 

 origin of the first and second subcostal nervules, both sometimes present, 

 sometimes absent. Hindwing rich dark piceous, becoming lio-hter to- 

 wards the costa, the latter broadly cinereous ; marginal white dots 

 none in some specimens, to a complete series of twelve in others • 

 a submarginal larger series varying from nine to ten, very inconstant in 

 size, when present always commencing from the apex of the wing ; 

 sometimes with, sometimes without two discal bluish-white spots 

 divided by the third median nervule beyond the discoidal cell. Under- 

 side, both loings rich dark piceous ; some white dots at the extreme 

 base of the wings; the markings as above, but invariably much 

 smaller, white, or bluish-white, as variahle as on the upperside; some- 

 times with, sometimes without a spot at the end of each discoidal cell. 

 Foreiving with the inner margin broadly cinereous. Female differs from 

 the male in the inner margin of the forewing being straight instead of 

 strongly outwardly bowed, and in the absence of the sexual brands on 

 the upperside, which are represented in some specimens by a small 

 blue streak ; all the markings on both sides in both wings as variable 

 as in the male. Underside, foreiving with two elongated bluish-white 

 streaks in the submedian interspace. This latter marking is very use- 

 ful, and by it a female Stictoploea can be at once identified, as it occurs 

 in no other group of Euplcea. 



The shape of the forewing in this species shews considerable varia- 

 tion, some specimens being much broader than others, while the apex of 

 the wing is also somewhat produced is some examples, much rounded in 

 others.
