basal half of the wings suffused with dark olivaceous green ; 

 black markings as in the $ but larger; on the fore wing the 

 spots of the subterminal series very large, coalescent or nearly 

 coalescent with one another and with the dentate spots on the 

 veins in the inner terminal line ; the upper two spots also of the 

 postdiscal series very large and coalescent, the upper of the two 

 joining on above and below to the inner postdiscal lunate spot in 

 interspace 6, thus enclosiug a prominent lunule of the ground- 

 colour. Underside as in the <$ , but paler.

Race issaea, Doubleday. — 3 . Upperside bright pale fulvous ; 

 base of both wings and upper dorsal area of hind wing suffused 

 with olivaceous brown. Eore and hind wings with black markings 

 as follow : — Fore wing : three transverse, short, slightly sinuous 

 bands across cell ; a transverse spot below, near base of inter- 

 space 1 ; a broad short band along the discocellulars, a zigzag 

 discal series of large black spots, the upper three connate, forming 

 a short oblique band from costa ; a postdiscal transverse short 

 patch below costa in interspace 6, followed by two transverse rows 

 of spots, the spots in the inner row rounded, in the outer row 

 somewhat lunular, the upper spots connate ; beyond these are 

 two parallel, slender, terminal transverse lines connected at the 

 veins by dentate dots. Hind wing : a short transverse mark in 

 cell, a broad line along the lower discocellular ; a discal and a 

 postdiscal series of spots, the spots in the former smaller than 

 those in the latter ; both series curved outwards at interspace 4, 

 then inwards and again outwards in interspace 1 ; a subterminal 

 series of lunular spots and two slender terminal lines as on the 

 fore wing. Underside a paler yellow. Eore wing : an inwardly 

 oblique short fascia from apex and the veins near the apex 

 ferruginous red ; the black markings on the basal two-thirds of 

 the wing as on the upperside ; the spot in interspace 6, the apical 

 three spots of the postdiscal series, and the apical four of the 

 subterminal series silvery. Hind wing with the following silvery 

 markings: — a precostal spot, two small spots at base of cell, an 

 elongate spot at base of interspace 1, two streaks on the 

 abdominal fold ; a discal series of three comparatively very large 

 spots, the middle spot subacute at apex, extending from middle of
