turing but rarely into the open. It is never seen basking on the 

 tops of hills, for, like its larva, it is not partial to the sunlight, except 

 when diluted through the dense shade of trees. It is a fast flying- 

 active insect, generally, seemingly, on the wing and very busy 

 either, in the case of males, looking for females or, in the case of 

 the latter, choosing a fit leaf whereon to deposit an egg or two ; 

 these are laid generally on the underside, but often, also, on a 

 shoot, stem or even, if conveniently situated, on a dead creeper-stem 

 or dry twig. The style of flight is that of Gwplia, though stronger 

 and faster ; the insects bask on leaves in shady places with their 

 wings half open ; they rest with them closed over the back. They 

 do not visit flowers much. They may be found in great numbers 

 round their food-tree in the monsoon months. This tree is 

 Uydjnocarjpus wightiana, Blume, of the botanical family Bixinece, 

 common in the evergreen forests of Kanara and the Konkan 

 generally, the large wood}?- brown fruit of which yields a yellow 

 oil iTsed in native medicine for skin diseases ; it is also xised for 

 lighting purposes. 



The genus Cirrhochroa contains seven species, according to 

 Bingham, occurring in British India ; others are found in the 

 Malayan region. 



70. Byblia ilithyia, Drury. — Wet-season form. — Male upperside: deep orange. 

 Forewing : the costa broadly jet-black to within a short distance of apex ; 

 cell crossed by three narrow, short, black bands, the inner and the outer 

 not reaching the median vein ; a very irregular, black, discal blotch from 

 dorsum to vein 4, continued very narrowly along that vein to meet an 

 oblique, irregular band, from just beyond the middle of the costa ; a post- 

 discal, broad, transverse, black band from dorsum to vein 5, with the 

 portions of the veins beyond it defined in black. The apex of the wing 

 beyond the broad black edging to the costal border has its upper margin 

 and the terminal portions of the veins defined in black ; finally a narrow 

 terminal band. Hindwing : an elongate black, subcostal patch near base, 

 continued posteriorly across the cell by an inner and outer series of small^ 

 transverse spots ; a complete, broad, black, postdiscal band with the 

 portions of the veins beyond it lined with black, and a narrow black 

 terminal band as on forewing. Cilia of fore and hindwings white, alter- 

 nated with brown. Underside : paler orange. Forewing : black markings 

 as on the upperside, but the cell and upper discal markings obscurely 

 margined on both sides by white ; an oblique, black line from costa to apex 

 of postdiscal transverse band, followed by an oblique, preapical series of
