197. Virachola isocrates, Fabrisius. Male (PL H., fig. 54) — Upper side -. 

 violet brown. Fore wing : with the colour darkening on the margins in cer- 

 tain lights, showing a bright violet gloss on the inner area ; an indistinct 

 orange-ochreoLis patch, varying in size in difierent examples, beyond the 

 cell, only visible in certain lights. Hind wing : with the costal area and 

 abdominal fold blackish-brown ; anal lobe whitish with a black spot in it, 

 varying in size in different examples, with some pale bluish-white scaling 

 on its upper side, in some examples the black spot nearly fills the whole of 

 the anal lobe ; tail black, tipped with white. Cilia of both wings with the 

 basal part black, the outer half white, becoming bluish-grey below the tail 

 and round the anal lobe. Underside vinous-grey, or slaty-grey, markings 

 darker than the ground colour, edged on both sides with white. Fore 

 wing with a bar at the end of the cell, a discal band of conjoined spots, 

 decreasing in size hindwards, nearly straight down, from near the costa to 

 below vein 2, where the spot is very small. Hind wing with similar discoi- 

 dal bar and discal band, the latter somewhat irregular ; the third, fourth 

 and sixth spots a little outside the others, then the band, with a sudden 

 curve, reaches the abdominal margin a little below its middle ; anal lobe 

 black with a white spot on its upper inner side, a smaller black spot tinged 

 with orange in the first interspace, with some blue, grey and white scaling 

 between them ; both wings with indications of a narrow, submarginal band 

 and very fine, marginal, grey line. Antennre black, ringed with white, 

 club with an orange tip, with a white streak below at its base ; frons 

 greyish-white ; eyes ringed with white ; head and body above and below 

 concolorous with the wings, abdomen below white. — Female. (P1.,H., fig. 

 54a) — Upperside brown. Fore wing : with the colour darkening towards the 

 margins, the orange-ochreous patch larger and more distinct and varying 

 much in extent, in some examples extending broadly to the base below the 

 median vein. Upperside as in the male, but the bands are broader and 

 more outwardly curved ; the black, anal spots larger. Expanse : male, 

 40 — 45 mm. ; female, 45 — 50 mm. 



Larva. — The shapz is exactly the same, practically, as that of Deudorix 

 epijarbas, with the same kind of anal end, i.e., a " shovel," circular and flat, 

 on the dorsal areas of segments 12-14 ; the general style of marking is 

 also similar. Head rather small, hidden under segment 2, shining, round in 

 shape and dark-brown in colour ; segment 2 semicircular in shape, thick- 

 ened round the margins, slightly emarginate in dorsal line on front 

 margin, evenly convex transversely, with a dorsal depression which has on 

 it a double, fine, dorsal line flanked on either side by a small, black spot ; 

 segment 3 broader and higher than segment 2, flat on dorsum or top, rising 

 suddenly from the front margin, that is forming a perpendicular declivity 

 from the surface of segment 2 ; segments 4-6 shorter than 3, the body 

 highest at segment 4, each of the segments 4-6 with a transverse dent 

 on dorsum ; segments 7-l0 about the same breadth — the larva is broadest 

 at segment 3 — with, each, a small, dorsal, elliptical indentation ; segments 

 3-10 have also a lateral, central longish depression or dent parallel to 

 the front and hinder margins : segment 11 is dorsally flat (as in Deudorix) 

 and not very distinguishable from the succeeding " shovel " segments : 

 the surface of the shovel-disc is pitted and the margins raised ; all seg- 

 ments very distinct except the anal ones, especially on the dorsoventral 

 margin which is somewhat flanged or thickened all round ; segment 18 

 a,bout the same breadth as segment 2 and the hinder margin of 14 is 

 semicircular. The surface of the larva is shining-oily looking, covered with 

 many small, tubercvilar, black hairs ; front margin of segment 2 and the 

 whole dorsoventral margin of body with a row of fine, short, white hairs 

 much longer than the tubercular, black ones ; on top of each segment 3-10
