98. ixias pyrene. — (PI. J, figs. 65 c?, 6oa$) — Diy season brood. — Male 

 upperside : deep sulphur-yellow. Fore wing : base and basal half of costa 

 thickly irrorated with black scales ; apical half of the wing black, with an 

 enclosed, large, irregularly triangular, orange-coloured patch, the apex 

 of which is more or less broadly rounded and blunt ; the orange colour 

 extends into the apex of the cell but is interrupted there by a black, 

 discocellular spot that spreads diffusely inwards and joins the black, 

 oblique bar which forms the base of the orange patch ; veins that traverse 

 this latter, black. Hind wing : uniform with a little black scaling at 

 extreme base ; termen with a dusky-black, somewhat narrow border 

 (sometimes entirely absent) which decreases in width posteriorly. Under- 

 side : a darker yellow, sparsely irrorated with fusco-ferruginous short 

 strigge and minute spots. Fore wing : base and posterior area broadly 

 similarly irrorated, with a whitish pale virescent tint ; the strigse and 

 minute spots most numerous towards the apex and along the termen ; 

 interspaces 4, 5, 6 and 8 with a curved, subapical series of small, rounded 

 dull-ferruginous spots and a similar spot on the discocellulars. Hind 

 wing also with a ferruginous spot on the discocellulars, followed by a 

 postdiscal series of similar spots in interspaces 3 to 8, all or most of them, 

 centred with white ; the spots in interspaces 5, 6 and 8 the largest, those 

 in 5 and 6 often coalescent. Antennae and thorax anteriorly dull-ferrugi- 

 nous ; thorax posteriorly and abdomen above, fuscous black ; head, thorax 

 and abdomen beneath : yellow. Female ujjperside : white, faintly tinged 

 with yellow. Fore wing : apical half black, with an enclosed, irregular, broad, 

 oblique patch of the ground colour that extends into the upper apex of 

 the cell ; on the innerside of this the black is reduced to a short, oblique 

 bar broadened at the lower apex of the cell, from whence it is continued 

 as a somewhat slender, diffuse, oblique streak to the tornus, where it 

 broadens again abruptly and meets the black on tl^ie termen ; the outer 

 margin of the oblique, white patch is irregularly crenulate, sometimes 

 triannulate ; the black colour on the apex often forms a right angle on 

 vein 4 ; on the white patch posteriorly there is a black spot in interspace 

 2 and another in interspace 3. Hind wing : uniform, a few subobsolete, 

 slender, fuscous, transverse strigse posteriorly ; the terminal margin some- 

 times with (more often without) a narrow, dusky-black edging, broadened 

 anteriorly <it the apices of the veins. Underside : similar to that in the 

 male, with similar markings, the ground-colour a dark, dull ochraceous, 

 the fusco-ferruginous strigse more numerous. Antennae, head, thorax and 

 abdomen as in the male. 



Wet-season brood. — Male and female zipj^erside : differs in the broader, 

 more pronounced, black, terminal edging to the hindwing which is often
