band is a more or less slender, irregular, similarly-coloured line; and 

 between the discocellular and upper discal bands another much shorter 

 line that extends from the costa downwards but does not reach vtin 4, 

 this is slightly clavate anteriorly and posteriorly. Hind wing : mottled 

 with brownish-black that leaves only basal, snbbasal, medial and discal 

 transverse lines or bands of the ground-colour; the medial and discal 

 bands, which are highly irregular, enclose here and there small brownish 

 markings, the bands themselves coalescing above a very irregularly shaped, 

 brown mark that is placed on the posterior half of the middle of the wing ; 

 terminal markings as on the fore wing but the subterminal spots larger, 

 the apical one especially so, the tornal two spots jet-black and each 

 j^ncircled by a glittering, slender ring of metallic, green scales. Cilia of 

 b)th fore and hind wing, the antennsB, head (frons black) thorax 

 and abdomen much as in T. theoph vastus, except that the abdominal white 

 bands do not reach the dorsum. Eyes haired. Female. — (PI. G., fig. 45a). 

 Upperside ; very closely resembles that of female T. theophrasivs, but the 

 extent of white on the fore wing is greater so that there is a greater area of 

 white to be seen between the brown markings superposed on it, these 

 markings have the appearance of an irregularly termed V on a white 

 background. Hind wing much as in T. thenphrastus. Uvderside : similar 

 to that of its own male, but the brown bands less broken, more regular. 

 Cilia, antennae, head, thorax and abdomen as in the male. Expanse : 

 IVJale and female, 22-31 mm. 

 ^ Fgff. — Turban-shaped, slightly depressed on top in the middle, has 

 aTjout 24 low, rounded ridges running from the centre on top in slightly 

 curved lines diagonally to the base in both directions — that is to the right 

 and to the left — so as to divide the surface up into many little diamonds ; 

 at the intersections of these lines are small, raised knobs, one to each 

 intersection, which are many times higher than the ridges ; the bottoms 

 of the little diamond-cell — the surface of the egg — is extremely finely 

 reticulated ; the cells on the top of the egg are very small, confused and 

 undefined. The colour of the egg is nearly white throughout and only 

 slightly shining. B : O. 5 mm. ;H ; O. 3 mm. 



Larva. — The larva is of the usual limaciform shape of the genera Nacaduba, 

 Cyanins,&c. ; it is broadest about segment 5, each segment is constricted at 

 margin, most so on dorsum where each segment is somewhat humped in 

 consequence, the highest part of hump being near the anterior margin ; the 

 greatest height is also about segment 6 ; the anal segment is somewhat 

 broad (in larval transverse sense), the humping very slight from segment 

 11 hind margin to anal margin, the anal portion somewhat suddenly narrow- 

 er than segment 12 and broadly rounded at end, the dorsal portion being 

 flattish, but the margins thick (no depression on dorsum however) ; seg- 

 ment 2 is semi-circular in shape, with the dorsum raised including nearly 

 the whole length of hinder margin but coming to a bluntly rounded portion 

 at front margin ; the centre of this raised triangular part being slightly 

 depressed ; the sides of larva are of course sloping from dorsum to larval 

 margin; each segment has a depression from near dorsal line down centre 

 to near each spiracle: rather slighc. The liead is small, the neck when 

 "pi-dtlruded very long ; the colour of head is black, very shiny, labrum whitish, 

 antennae brownish : clypeus large and triangular; shape round. The sur- 

 jfaceoi the larva is dull, with the segmental margins constricted as stated 

 above, a depression down centre of segments 3 to 11 ; the usual round 

 (>periing8 with white cylindrical tubes protrusible on segment 12 ; the 

 -fhonth-like, traupverse gland-slit on segment 11 ; the whole surface besides 

 ooivered with minute, sessile etar-.topped hairs, white on the white portions, 

 .black pn the brown. The f5;?iV«c/es are small, white, roundish, flush, The
