NYMPHALIDiE. 



very short, about a quarter the length of the wings ; veins 3 and 4 

 shortly stalked beyond lower apex of cell ; veins 5, 6 and 7 

 approximate at base, 8 bent strongly upwards near base of wing. 

 Body slender ; antenna? longer than half length of fore wing, 

 club long, slender : palpi, eyes and legs as in Gyrestis.

<S $ . Upperside : from a rich dark reddish ochraceous to a much 

 paler shade of the same colour. Fore and hind wings crossed 

 transversely by the following slender black lines more or less 

 parallel to the body : a basal and subbasal pair, a discal single line, 

 a postdiscal pair of lines, and a subterminal line. The interspace 

 between the basal and subbasal pair of lines irrorated with dusky 

 scales ; the postdiscal pair convergent posteriorly, the interspace 

 between them traversed medially b} r an irregular black fascia 

 broken and interrupted on the fore wing ; on the hind wing there 

 is, in addition, an obliquely-placed, diffuse dusky-bluish fascia from 

 apex to tornus, the tornal lobe and angle with a diffuse bluish 

 spot and two minute black specks above it. Underside slightly 

 paler, the black markings as on the upperside. Antennae ochra- 

 ceous brown annulated with white ; head, thorax and abdomen 

 ochraceous ; the latter two with dark lateral stripes ; beneath 

 much paler ochraceous. 



The ground-colour in many specimens is a much paler ochra- 

 ceous yellow, with the markings darker ochraceous, not black. A 

 series of dated specimens would probably show them to be the 

 dry-season form.
