It differs from that species in that the apex of the forewing is more falcate; the postmedial line is double below CuA 1 ; a pale gray terminal line is present; the patches between M 3 and CuA 2 , especially their dark center spots, are much smaller. In the male genitalia, two lobes of the uncus are nearly triangular, apart from each other, with the posterior margins oblique. But in T. finita , the lobes of the uncus are nearly quadrate and close to each other, with the posterior margins truncate. Material examined.

Remarks. Chu & Wang (1988 , 1991 ) recorded T. adelpha Swinhoe from Tibet (Zham, Nyalam) and Yunnan (Lijiang). We have reexamined the materials labelled as “ adelpha ”, and have concluded that the specimens from Tibet (Zham, Nyalam) are T. sadana (Moore) , and the specimen from Yunnan (Lijiang) is T. finita Watson. So T. adelpha Swinhoe is not at present known to occur in China .
