urea from costa to vein 4 very oblique and irregular, between veins 

 2 and 4 excavate on the inner side, this excavation outwardly 



rounded between the veins 

 and inwardly toothed on 

 vein 3; below vein 2 the 

 black area is suddenly di- 

 lated into a square spot 

 which occupies the whole 

 of the tornal angle; the

b. Underside fore wing, dry-season brood. concave. Hind wing : 



terminal margin with a 



narrow black band which is attenuated anteriorly and posteriorly ; 

 dorsal margin broadly paler than the ground-colour. Underside : 

 yellow, generally a slightly paler shade than that of the upperside, 

 with the following reddish-brown markings : Fore wing: two small 

 spots or specks in basal half of cell and a reniforin spot or ring on 

 the discocellulars. Hind wing : a slightly curved subbasal series 

 of three small spots, an irregular slender ring or spot on the 

 discocellulars, followed by a highly irregular, curved, transverse, 

 discal series of spots or specks, some or all of which are often 

 obsolescent. On both fore and hind wings the veins that attain the 

 costal and terminal margins end in minute reddish-brown specks. 

 Antennae greyish yellow, the club black ; head, thorax and abdo- 

 men yellow, shaded with fuscous scales ; beneath : the palpi, thorax 

 and abdomen yellowish white. The sex-mark seen from above 

 appears as a thickening of the basal half of the median vein oil 

 the fore wing. $ . Very similar, the sex-mark of course absent ; 

 the black areas on both fore and hind wings slightly broader, with 

 the inner edge of the black terminal band on the hind wing often 

 diffuse. Underside : ground-colour and markings as in the 6" . 

 Antennae, head, thorax and abdomen similarly coloured. 



Dry-season brood. <3 $. Upperside: ground-colour and markings 

 much as in wet-season specimens, the emargination on the inner 

 side of the black area and the tornal dilatation on the fore wing 

 similar. On the hind wing, in the great majority of individuals, 

 the black terminal band is also similar, in a few it is narrower and 

 diffuse inwardly in both sexes. Underside : ground-colour similar 

 to that in wet-season specimens, but in very many with a greater 

 or less irroration of black scales over the yellow parts of the wing ; 

 the reddish-brown markings on both fore and hind wings are also 

 similar, but the spots are larger, more clearly defined, darker, and 

 therefore far more conspicuous. In addition, on the fore wing 

 there is a preapical, very prominent, transverse, elongate spot or 

 short bar of reddish brown extended downwards from the costa. 

 This spot is irregular in shape and of variable width, but does not 

 seem ever to spread outwards to the actual edge of the termen. 

 In a few specimens there is also a small reddish-brown spot in
