7. Poritia potina. (Tab. XXII., fig. 7 ? .) 



Poiitiu poiina, Hewitson, Traus. Ent. Soc. 1874, p. 3-17; Ills. Dinrn. Lcp. Lye. p. "215, n. 4, t. 88, 

 figs. 6 & 7 2 (1878). 



" Upperside. Female. — Piufous-orange. Anterior wing with the apex, the outer and iuucr margins, 

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

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



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

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

 the middle by two bands (near together) of the same colour." 



Exp. wings, " l-iTi inch." 



Hab. — Malay Peninsula; Singapore (Wallace — coll. Hewits.). 



Genus CUEETIS.

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

 straight to apex, which is either subacute or prominently and falcately acute ; outer margin concavely 

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

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

 end of cell, thuil 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, clothud with tine adpressed scales; apical joint slender, 

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

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

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

 two small apical claws. 



The geographical range of Curetis inchides Continental India, Ceylon, the Andaman iind 

 Nicobar Islands, Burma, the Malay Peninsula, and probably the 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 tln-ee 

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

 in C. ccsopus ; secondly, in which the female pale markings are of an ochraceous character, 

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

 the male approaches the pecuUar markings of the female, as in C. spcrthis.
