Diagnosis. The species is hard to distinguish from C. dentata on external characters. However, the two species are quite different in their genital structures. In the male genitalia of postvittata, the saccus is much longer, about twice as long as the uncus, but it is almost equal to the length of the uncus in C. dentata; the length of the sclerotized process of the aedeagus is much longer; the vesica has two cornuti, one is rod-like, the other long triangular, while in C. dentata, the vesica has one stout spine-like cornutus which is deeply dentate on one side of the terminal half. In the female genitalia, the ductus bursae is narrower than in C. dentata .

Material examined. SUMATRA (BMNH): 1 ♂, Lebong Tandai, 23–30.IX.1921, C J Brooks coll. No 1754, BM1936-681, slide no.14387. INDIA (BMNH):1♀, Khasis Hill, Assam, Rothschild bequest BM1939-1, slide no. 14383.

Distribution.? China (Taiwan, Hong Kong), India, Bangladesh, Sri Lanka, Sundaland, Malaysia (Sarawak), Indonesia (Sumatra).

Remarks. We have not ourselves been able to examine material from Hong Kong or Taiwan, but we think it likely that records of C. postvittata from Taiwan and Hong Kong, which have been widely published, are misidentifications of C. dentata . If this is the case, then it seems probable that C. postvittata does not occur in China at all.
