from Nikkoj Central Japan. 135 



apical silver spots on the primaries, five of them forming a 

 decreasing submarginal series, the ground-colour duller and 

 more uniform in tint : secondaries with all the silver spots con- 

 siderably larger, the third series well defined and continued to 

 the submedian vein, so that there are five complete series ; the 

 submarginal series formed of broad black-bordered arched 

 spots; the ground-colour rather deeper, the ocelloid ferruginous 

 spots frequently larger than in the male, but always darker. 

 Expanse of wings 2 inches 10 lines to 3 inches 3 lines. 



A long series of specimens. 



The natural position of this species will be between A. 

 vorax and A.pallescens ; it appears to represent A. chloradippe 

 in Japan. 



Colias Elwesii, sp. n. 



c? . Above lemon-yellow, the basal three sevenths and costal 

 border of primaries densely irrorated with greenish grey ; 

 basal fourth of costal margin feiTuginous ; apical area (from 

 apical two fifths of costa to external third of third median 

 branch) and a broad external border, sinuated in second 

 median interspace and at external angle, black ; a subapical 

 series of irregular yellow spots, a large broad lunate spot on the 

 border in the first median interspace and a small spot below it 

 yellow ; a large black discocellular spot : secondaries irrorated 

 with grey ; a submarginal series of large subconfluent sulphur- 

 yellow spots, bounded internally towards the costa by a few 

 blackish scales ; apical border and three large spots at the 

 extremities of the radial and second and third median brandies 

 black ; fringe varied with rose-colour ; a large bright orange 

 spot at the end of the cell : body normal. Under surface 

 lemon-yellow, the characters of the upper surface indistinctly 

 traceable through the texture of the wing, costal margins and 

 fringes rose-coloured : primaries with a diamond-shaped silver- 

 centred black discocellular spot; three squamose blackish 

 spots parallel to the outer margin on the median and interno- 

 median interspaces : secondaries with an ochreous-bordered 

 purple-edged silver spot at the end of the cell ; a discal 

 arched series of purplish-red dots commencing with an angular 

 spot of the same colour upon the costa : body Avhitish, legs 

 rosy. Expanse of wings 2 inches 8 lines. 



$ . Above like the male, excepting that all the submarginal 

 lemon-yellow spots of the secondaries are bounded internally 

 by blackish scales, which, however, get less distinct towards 

 the abdominal area ; below with rather brighter primaries, 

 the three discal spots larger, brown, and the series continued 

 by two smaller brown spots or dots on the radial interspaces
