d. Hyparete group. Lower wings beneath with the basal region 



yellow, and a submarginal band of red, 



white or yellow spots. 

 6. Nysa group. Lower wings beneath black, yellow-marked 



at the base, and with yellow submarginal 



spots. 

 Note. — The extensive hyparete group is further subdivided in

Form of T. pasithoe, but the upper wings with the outer mar- 

 gin concave. 



Male. — Above, black : upper wings with a bluish-white band 

 formed by a large spot in the cell and two below it as in T. pasi- 

 thoe, but larger and more defined, the outer band of spots and 

 that at the end of the cell absent or very faintly indicated ; lower 

 wings with a patch of rich yellow between the cell and the ab- 

 dominal margin and reaching the second median nervule ; a faint 

 bluish-white patch across the cell to the inner margin, no sub- 

 marginal spots. Beneath : the uppers have a distinct white band 

 across the wings, a spot at the end of the cell and four small 

 linear spots across the apex ; the lower wings have the spots rich 

 yellow, disposed as in T. pasithoe, but leaving a broader black 

 border, and the outer spots all very small ; the red semicircular 

 band is narrower, and does not extend beyond the costal nervure 

 to the margin of wing as in T. pasithoe. 



Female. — Above, as in the male, but the band across the 

 uppers is whiter and more defined, and the yellow patch of the 

 lower wings is paler and extends into the discoidal cell. Beneath 

 it differs in the same manner from the under surface of the male, 

 every spot and band being the same but rather more developed, 

 and there are five spots instead of four in the apical band. 



Expanse of wings: male 3 inches ; female 5t inches. 



2ffl6.— Manilla (Coll. W. W. Saunders). 



A beautiful species, closely allied to the Indian T. pasithoe.
