TERIAS. 245- 



rouuded, in a few forms acutely pointed but not produced ; termen 

 straight ; tornus rounded ; dorsum bisinuate, very long, about 

 seven-tenths the length of the costa ; cell not quite half length of 

 wing ; vein 6 from end of basal fourth of 7, upper discocellular 

 therefore absent ; middle discocellular concave, short, half length 

 of lower ; lo\ver discocellular long, concave ; vein 8 absent, vein 9 

 from end of basal half of 7 ; veins 10 and 11 free, from apical half 

 of subcostal, the former given off just before upper apex of cell. 

 Hind wing : broad, broadly oval or slightly pear-shaped ; costa 

 arched, apex and termen continuous and strongly curved ; tornus 

 obtusely angular, the angle distinct ; dorsum broadly arched ; cell 

 short and broad at apex ; the discocellulars more or less transverse, 

 not oblique, the lower the longest, concave ; vein 7 given off from 

 subcostal close to upper apex of cell, vein 8 long, strongly curved 

 at base ; precostal vein rudimentary. $ with or without sex- 

 marks ; in one group on the upperside of the fore wing, in another 

 on the underside of the fore and upperside of the hind wing, in, 

 two groups entirely absent. 



Key to the forms of Terias. 



A . Fore wing underside : no markings in basal 



half of discoidal cell. 



a. r? without secondary sexual characters, c? 

 and fore wing : underside without any 

 markings, speekless. Hind wing : upper- 

 side without auy black terminal edging . . T. harina, p. 249. 

 l>. <$ without secondary sexual characters. < 

 and $ fore wing : underside with two 



minute black dots on discocellulars T. Ubythea, p. 247.. 



c. c? with secondary sexual characters on both 



fore and hind wings, tf and 2 f re wing : 



underside with a short, black, very slender 



undivided line on discocellulars. 



a'. Fore wing : acuminate at apex, terminal 



black band on upperside not extended 



to tornus T-. la-ta, p. 248. 



b' '. Fore wing : not acuminate at apex, ter- 

 minal black band on upperside extended 

 to tornus T. venata, p. 246. 



B. Fore wing underside : small black markings 



in basal half of discoidal cell, or if these 

 are absent then terminal black area on upper- 

 side of fore wing dilated into a square spot 

 on tornus. tf with secondary sexual charac- 

 ters on fore wing only. 



a. Fore wing underside: two small reddish- 



brown markings or spots in basal half of 



discoidal cell T. hccabc, p. 250. 



b. Fore wing underside ; one small black or 



reddish-brown marking in basal half of 

 discoidal cell. 



a'. Fore wing upperside : inner edge of black 

 terminal area anjnilated on veins 4 and 7 ;
