postmedial, lunulate, oiitwartllj' convex ; interspace 1, two of which one 

 is more or less siibbasal, the other postmedial : 2 and 3, one at base of each 

 interspace ; interspaces 4, 5 including cell : one subbasal, one medial (the 

 discocellular band), one postmedial, bilunulate, outwardly convex, paral- 

 lel ; 6, one medial to the interspace ; 7, one subbasal, one medial ; none in f>. 

 The subbasal pairs of lines form a subbasal band from vein 1 to vein f<, 

 the middle portion of which, composed of the cell band, is displaced inwards 

 so that the outer line is half way between Jthe lines of the upper and lower 

 parts or pairs. Antennte black above, the club also altogether black 

 with a white anteapical band and a greyish tip ; palpi black : head, thorax 

 and abdomen purplish-brown ; beneath : antennae black, thinly banded 

 white reaching onto the sides ; palpi white fringed with black ; eyes 

 rimmed with white, frons black : thorax bluish-white, longly haired ; 

 abdomen whitish. Female, (PI. G, fig. 43a). Upperside : fore wing : eosta, 

 including half the cell and above vein 5 including the whole apex, and a 

 terminal edging that occupies about one third of the wing, slightly narrow- 

 est in interspace 3, jet-black ; tho remainder of the wing white shaded at 

 the base and along inner margin broadly with greyish-blue which, in 

 certain lights, has a beautiful, opalescent, blue iridescence : the veins 

 black outwardly ; the base clothed with sparse, appressed, rather long, 

 white hairs. Hind wing : the costa above the cell and vein 6 dusky-black ; 

 posterior portion of wing whitish-grey, the base shot with the same blue- 

 as on fore Aving, with the veins blackish : a comparatively well-defined, 

 transverse postmedial series of dusky blackish, inwardly-convex lunules 

 edged inwardly and outwardly by thin, white lines ; followed by a slightly 

 narrower series of dusky-black spots edged outwardly again with white,, 

 the spot in interspace 2 generally more prominent; an anticiliary, fine, 

 black line ; the cilia light grey : tail at end of vein 2 thread-like, black, 

 tipped with white. Underside : markings as in the male but the colour of 

 ground grey tinted with brown, the transverse, white lines broader and 

 more diffuse with the middle of the portions enclosed by these lines often 

 lighter forming an obsolescent sort of medial line, the lines on the fore 

 wing a little bit more irregular ; an extra white, short line along the base 

 of vein 7 (not really extra but. in the male, this is hardlj' noticeable); the 

 inner series of oblong, inframarginal marks on the fore wing are nearly 

 black in interspaces 1 and 2 — or, at any rate, very dusky. Otherwise as- 

 in the male. Expanse : 30-32 mm. 



iv/y. — The egg is tnvhun-sfiaped : the top only very slightly concave ; the 

 change from the top to the sides is gradual and rounded ; indeed the top 

 can only be said to be sunken near the middle where the micropyle is 

 situated, the surface is shining and covered all over with high, but not par- 

 ticularly thick-walled, seemingly 4-sided cells with a little, round-topped, 

 somewhat flattened knob or prominence at each intersection which becomes- 

 more or less obsolescent immediately around the central depression which 

 is moderately large and surrounded by a few small cells in a couple of rows,, 

 the bottom of the depression minutely pitted ; around these two rows of 

 small cells the others rapidly get larger down to the sides and the rows 

 are very diagonally arranged so that it is nearly impossible to say how 

 many rows there are from top to base : there are about 8 or 9 cells from 

 the central depression along a diagonal row and, perhaps 6 along a meri- 

 dional line ; there are about 24 cells in a complete circumference at the 

 broadest part which is some way above the base ; each intersection-knob is 

 surrounded by six others and the shining top of each knob is connected by 

 very thin, white ribs or lines which run down its sides and across the open, 

 so to speak, up to another knob ; there are about ten such thin lines dnwn 

 each knob, i.e., more than one to each surrounding knob. The colour of the
