spots of which on the fore wing are en echelon, while the band on the hiod 

 wing is bisinuate and is capped anteriorly near the costa by a seventh 

 round, black spot eccircled with white ; the above are followed by macu- 

 lated inner and outer subterminal bands, which on the hind wing are curved 

 and more or less interrupted on the tornal area by a comparatively 

 large round black spot in interspace 2 and a smaller similar spot in inter- 

 space 1, both spots inwardly crowned with ochraceous ; the Avhite edgings 

 on the inner side to both subterminal bands on the hind wing are more or 

 less lunular ; an anteciiiary, blackish line bordered intermittently with 

 white ; cilia light brown. In addition on the same wing there is a sub-basal 

 curved row of four white-encircled spots, of which the anterior two and 

 the spot on the dorsum are black, the other dark brown. Antennas black, 

 shafts ringed with white ; club tipped orange ; head f rons white and black, 

 thorax and abdomen brown, the head and thorax clothed with bluish hairs ; 

 beneath: palpi, thorax and abdomen whitish. Female. XJ 'pferdde : brown. 

 Fore wing : shot with blue from base outwards for a little over half its length 

 down its middle, this blue irroration not nearly extended to the costal 

 margin ; a slender anteciiiary black line. Hind wing : blue like the fore wing 

 but dark with a touch of blue iridescence near base ; terminal markings much 

 as in the male but the subterminal spots larger and often those in in- 

 terspaces 1 and 2 more prominently crowned with orange and not extended 

 beyond interspace 6 ; in addition postdiscally there is a lightening of the 

 shade of the ground-colour, between which paler area and the subterminal 

 spots the ground-colour assumes the form of a postdiscal, short, transverse 

 lunular band. Underside as in the male, the marking slightly larger and more 

 clearly defined. Antennae, head, thorax and abdomen as in the male but 

 slightly paler. 



Dry-season brood. — Male and female. Very similar to the same sexes of 

 the wet-season brood, but can be recognized by the following differences : 

 ^ — Upperside : Male. Ground-colour slightly duller; subterminal spots on 

 the hind wing less clearly defined. Female. The blue shot area extended 

 outwards on the fore wing for three-fourths of its length from base, but, as 

 in wet-season specimens not reaching the costal margin ; on the hind 

 wing the blue suffusion covers the entire medial portion of the wing from 

 the base to the subterminal row of spots, of which latter the spot in inter- 

 ispace 2 is entirely without the inner ochraceous edging. Male and female. 

 Underside: ground-colour darker than in specimens of the wet-season 

 brood, the discocellular and discal transverse bands on both fore and hind 

 wings broader, the terminal markings very ill-defined, the inner white 

 edging to the inner of the two subterminal transverse bands broadened 

 and very diffuse. On the hind wing the discocellular and discal bands 

 coalesce and form an ill-defined, diffuse, medial cloud on the wing. Ex- 

 panse : male and female, 24-32 mm. 



Larva. — Normal ; segment 2 on the whole more or less semi-circular 

 in outline but with a small indentation on front margin in the dorsal line, 

 giving the impression of a truncation ; the usual dorsal depression : 

 segment 2 somewhat broader and higher than the preceding ; the breadth 

 of body after that the same up to segment 12 after which it decreases 

 again to the rounded anal extremity ; segments 13, 14 with the dorsal 

 line sloping down at an angle of 30° to the longitudinal axis of body. 

 The head small, round, shining, with a small, triangular clypeus ; black 

 in colour with the antennas white, hidden under segment 2 : the colour 

 may be yellow. Surface of the larva is dull and rough looking ; thert- 

 is a central, dorsal depression to each segment which is mote or less in 

 the nature of a wide pit ; the segment-mareins are well marked ; the 

 whole dorsa of segments. 13, 14 are distantly pitted with pin-point pittings ;
