I'fntia putina, Hewitson, Trans. EnL Soo. 1874, p. 847; Dls. Diuni. Lcp. Lye. p. 215, n. 4, t. 68, 

 figs. 6 & 7 ? (1878). 



" Upperside. FemaU, — Rufoua -orange. Anterior wing with the apes, the outer and inner margins, 

 and a linear spot at the cad of the cell dark brown. Posterior wing angular a little below the apes, clouded 

 with rufous -brown, and marked by three large brown spots ntar the outer margin," 



" Underside rufous, tinted with lilac. Both wings with a linear spot at the end of the eell ; both 

 crossed before the middle by a rufous-brown band (broken into spots on the posterior wing), and beyond 

 the middJe by two bands tnear together) of the same colour/' 



Exp. wings, " Itli inch."

Genus CUKETIS.

Anterior wings subtriangular ; costal margin strongly arched at base, and then almost obliquely 

 straight to apes, which is either subacute or prominently and falcately acute; outer margin cone avely 

 sinuate where the apex is produced ; inner margin concavely sinuate in the male, obscurely so in the 

 female ; lirat subcostal nervule emitted at about one-third before end of cell, second at one-fourth before 

 end of cell, third and fourth bifurcating about midway between end of cell and apex of wing. Posterior 

 wings rounded, the anal angle more acute in the male than in the female ; subcostal nervules bifurcating 

 near end of cell. Eyes hairy; palpi porrect, clothed with fine adpressed scales; apical joint slender, 

 longer in the female than in the male ; antenna? short, gradually thickened into a long apical club ; legs 

 short, thick and densely clothed with scales; anterior tarsus uf the male consisting of a single joint, with 

 an obtuse apical claw and with some line spines beneath ; anterior tarsus of the female five-jointed, with 

 two small apical claws. 



The geographical range of Curctis includes Continental India, Ceylon, the Andaman and 

 Nicohar Islands, Burma, the Malay Peninsula, and probably tbe whole length and breadth of 

 the Malayan Archipelago, 



This genus exhibits features of structural variability which await the explanation of the 

 local biological observer. In structure, the apical angles of the anterior, and the anal angles of 

 the posterior wings are either acutely produced or obtusely subacute. There are also three 

 forms of sexual dissimilarity ; firstly, in which the female has the pale markings whitish, as 

 in ( '. H'sopus; secondly, in which the female pale markings are of an ocbraceous character, 

 as in C. feldm, both of these forma having the male entirely dissimilar ; and thirdly, in which 

 the male approaches the peculiar markings of the female, as in C\ sperthis*
