Description, q*. ?• Palp dull scarlet. Head yellow above labrum, reddish brown below 

 antennae, buff between and posterior to antennae. Antennal shaft pale buff dorsaHy. 



Anterior margin of thorax very pale yellow dorsally, becoming darker yellow then dull pink 

 posteriorly. Ventral surface of thorax pale yellow, with scarlet band ventral and lateral to eye. 

 Fore legs with scarlet front surface, rest yellow ; remaining legs similarly but less intensely 

 coloured or uniformly yellow. 



Wing shape as in Plate 10, fig. 312. Ground-colour of upper surface of both wings yellow 

 striate with brown and reddish brown, sometimes speckled with reddish brown or entirely 

 reddish brown proximal to postmedial fascia on fore wings and proximal to antemedial fascia on 

 hind wing (see remarks below on variation) ; costal area of fore wing, apical part of fore wing 

 (except for black apical spot and narrow surrounding area) and narrow terminal band on hind 

 wings much more lustrous than rest of wing. Upper surface of fore wing with white discocellular 

 spot ; reddish brown postmedial fascia ; black comma-shaped apical marking ; reddish brown 

 subterminal marking immediately anterior to Cu lb and another above \A ; marginal area 

 speckled with reddish brown scales or entirely reddish brown. Reddish brown antemedial fascia 

 clearly marked on upper surface of hind wing ; area proximal to this fascia occasionally speckled 

 with reddish brown or entirely reddish brown. Under surface of both wings pale yellowish buff, 

 striate or speckled with reddish brown in some specimens. Fore wing more reddish at base, 

 especially in costal area and in narrow terminal band ; postmedial fascia reddish brown often 

 faintly marked. 



Abdomen similar in colour to the adjacent parts of the corresponding surfaces of the hind 

 wings. Antemedial fascia of hind wing continued across abdomen as transverse band. 



$ genitalia (Text-fig. 228) : uncus and (?) gnathus bifid ; diaphragma with paired, setose, 

 dorsoventrally flattened invaginations ; valves digitate, setose ; aedeagus arcuate ; eighth 

 sternum greatly modified, deeply emarginate medially at posterior margin. 



$. Similar to male externally. 



$ genitalia (Text-fig. 229) : heavily sclerotized ; ostial segment forming thick collar round 

 ovipositor lobes ; ostium covered ventrally by deeply emarginate plate ; bursa copulatrix with 

 single, ovate, concave, spinose signum. 



Measurements. A.P.R. : $, $. 19. Wing : $. 15-0, 13-5-170 mm. (12) ; $. 16-5, 

 I5-5-I7-5 mm - (3)- 



Discussion. The presence of individual variation has been mentioned in the 

 description. There is a tendency towards a darkening of the coloration of the area 

 proximal to the postmedial fascia on the upper surface of the fore wing and proximal 

 to the antemedial fascia on the hind wing. In most specimens there is only a light 

 speckling of reddish brown scales on these areas, but in a few examples the wings may 

 be almost uniformly coloured and in others the basal areas are almost completely 

 reddish brown. In the latter darker specimens the terminal part of the fore wing is 

 also a darker reddish brown colour and that part of the dorsal surface of the abdomen 

 adjacent to the dark basal part of the hind wing is reddish brown.
