30 LEPIDOPTERA INDICA. 



Chrysalis. — Head-piece obtusely pointed in front, thorax rounded, anterio- 

 dorsum arcbed. 



Habits of Imago. — Under reference to R. Eorchnia, Mr. J. Beetham (Journ. 

 Bombay N. H. Soc. 1890, 280) says, " The flight of the butterflies of this genus is 

 pecuHar. Thej^ seem to float and sail along, so that when on a level with the eye 

 they disappear and re-appear; when settled on leaves as is their habit, they rest with 

 wide expanded wings." 



Habits and Food-pi,ants of Larva. — According to the observations made by 

 Mr. J. Davidson and E. H. Aitken in the N. Kanara District, Bombay, " The larva 

 may be found on several species of Acacia, and has the curious habit of feeding by 

 pi'eference, not on green leaves, but on those which it has caused to wither. The trees 

 on which it feeds have all bi-pinnate leaves with minute leaflets. It bites through 

 one or two pinnas, which immediately droop and dry up, but are kept from falling by 

 a few threads of silk with which the larva has taken the precaution to attach them 

 to the central leaf-stalk. Thenceforth it lives among them and feeds entirely on 

 them. The fore and underparts of the larva is of a dark greenish-brown, the rest is 

 just that shade of greenish-grey which the leaves assume when withered, and is 

 crossed by diagonal dark bands exactly representing the spaces between the leaflets 

 — a most perfect disguise."

Imago. — Male. Upperside rich dark olivescent reddish-brown ; cilia slightly 

 alternated with white. Foreioing with a reddish-ochreous discoidal streak occupying 

 the lower half of the cell and extending broadly beyond it to middle of the disc 

 above and below the upper median veinlet, being also distinctly indented above 

 opposite the discocellulars and less so at a short distance inward; a transverse 

 discal excurved broken band composed of a sinuously formed subapical portion and 

 a more regular lower portion; followed by an inner submarginal obscure grey 

 undulated line, a more or less-defined darker orange-red slender middle submarginal 

 line, and then by an outer marginal obscure grey line. Hind wing with a reddish- 

 ochreous broad inner-discal band, its outer edge curving upward towards the costa.
