having four branches [inchuling the terminal portion], all the branches free ; the upper dis- 

 coidal nervule more remote from the subcostal than from the lower discoidal nervule ; the 

 lower disco-cellular nervule highly convex in the middle. Hindwing with the upper trunk 

 of the nervules more deflexed ; the third incdian nervule not at all bent ; the internal nervure 

 lower, shorter, and more bent." (^Fdder, I. c.) 



This genus contains the largest and handsomest butterflies of tlic suljfamily ; indeed 

 S. camadcvit and S. loiiisa are amongst tlie most sjilendid of tiie butterflies occurring in India. 

 Only five species are known, of which three are included in the Indian list, but the authority 

 for one of them, S. nourmahal, is doubtful ; the other two are found one in China, 5. hoivqiia, 

 and the other in Cambodia, S. cainbodia. They all have in a more or less defined degree a 

 curiously arranged series of spots on the outer margin of the forewing, consisting of a 

 triangular or diamond shaped submarginal series, the outer corner of each produced and 

 coalescing with a marginal series of concave lunules. The secondary sexual characters of the 

 male insect consist only of a small erectile tuft of hairs on the hindwing near the base of the 

 subcostal nervure ; in colour and pattern the sexes are similar so far as is known.

Description : "Upperside : Forewing white, tinged with a delicate purplish leaden 

 colour, the base of a rich brown ; with a row of lozenge-shaped spots, and another of brown 

 continuous lunules near the outer margin, Hindwing brown, the base of a richer colour ; con- 

 siderably beyond the middle is a row of large leaden- white lunules, and a smaller row close to 

 the margin of the wing. Underside : The basal portion of both wings is of a delicate buff 

 with a slight greenish tinge, and the apical portion fulvous ; a broad irregular fulvous fascia 

 runs across both wings before the middle, edged on each side by a black line, and beyond the 

 middle, each wing has a row of five red ocelli, with black irides, beyond which are two pale 

 brown continuous fascioe. The three or four round brown spots on the upperside preceding the 

 rows of lozenge-shaped marks near the extremity of the forewing occupy the place of the 

 ocelli of the underside ; and the broad row of white lunules on the hindwing is the continua- 

 tion of the pale space between the lozenge-shaped spots and row of lunules of the forewing ; 

 since, in a strong light, the dark ground-colour of the hindwing also exhibits a row of still 

 darker-coloured lozenge-sliaped spots, preceding the pale lunules. On the underside of the 

 forewing the broad fascia is dilated on the anterior half of the wing, so as to include half of 

 the discoidal cell and the like distance beyond it, inclosing a black lunule which marks the 

 nervule which closes the cell ; the ocelli are preceded by a longitudinal darker cloud ; the 

 larger ocelli bear a slender white central lunule, and the red pupil is separated from the black 

 iris by a fulvous ring ; the anal angle is marked with a black spot, outwardly edged with 

 white. The upperside of the body is brown, but the underside, with the palpi, legs, and 

 anal area of the hindwing, are fulvous." {IVestwood, 1. c. in Cab. Or. Ent.) 



*' The general appearance of the two sexes is nearly identical ; the male has a tuft of hairs 

 at the base of the hindwing, on the upperside." {IVeslwood, 1. c. in Trans. Ent. Soc. Lond.)
