Soc. vol. vi. no. 3 (1891), p. 377, t. G. fig. 25 $ . Two males of this remarkable insect from Margharita. The female, which has been described and figured by de Niceville, is very unlike the male. CHOASPES BENJAMINI, var. Thymele benjamini, Guer. Del. Voy. Inde, ii. p. 79, t. 22. 2, 2a (1843). There are two forms of this which may be distinct, but I have a series of them only from Sikkim.
