hair. Underside similar to the allied form. Fore wing with costal 

 two-thirds metallic greenish-blue. Hind wing with basal two-thirds 

 metallic greenish-blue limited by the postdiscal band, which is 

 represented by a fine white line, thickened at its lower end. Distal 

 area purplish. Black anal lobe as in allied forms. 



Length of fore wing : 23 mm. 



Interior, May, 1920, one S . 



22. Tagiades boivringi sp. nov. (pi. XXIV, figs. 24, 25). 



We can find no near ally of this species, but in pattern it is 

 reminiscent of Orthopetus lidderdali Elw. 



S . Upperside of fore wing black-brown with a bluish sheen, and 

 with hyaline spots. A spot in the cell, four discal spots in lb, lc, 2 

 and 3, the lower one the smaller, the second more distal, the third 

 larger than the others and more proximal, the fourth more distal ; 

 a forked marking in 3 between discal spots and cell, two hyaline streaks 

 in 2 between discal spot and cell, a hyaline streak in cell along lower 

 edge ; a series of five subapical spots, the two upper ones a little 

 smaller than the others, the third spot more distal, the two lower more 

 distal and one below the other. Hind wing with black-brown ground- 

 colour, basal half covered with short hair of ochreous-yellow colour. 

 A distal series of ovate spots of ground-colour outlined with yellow, the 

 four anterior spots faintly outlined, the posterior four with yellow outer 

 patch extending to a point on the margin. A round spot of ground- 

 colour in the cell at its end. Fringe ochreous-yellow from base to 

 vein 5. 



Underside of fore wing as above, but with a submarginal series of 

 small greyish somewhat lunulate spots, the two lower ones only 

 distinct. Inner margin pale yellow as far as the lower discal spot. 

 Hind wing with markings as above. A yellow stripe between cell-spot 

 and base, and a yellow patch between cell-spot and the postdiscal spot 

 in 4 and 5. The yellow ground of the four lower spots is prolonged to 

 a point basad in each case. Cellule lb ochreous-yellow. The three 

 anterior spots are edged with grey-white distally. 



Antennae black-brown. Head black-brown, frons edged with 

 yellowish-white, a yellowish-white spot at base of antennae. Thorax 

 covered with yellowish-green and black-brown hair. Abdomen black- 

 brown narrowly ringed with grey-white, basal segments fringed with
