Alg., Zool. iii. p. 350, n. 14 pi. 1. fig. 2 (1849). cf 2 , Huswah, 30th March and 18th May ; cf, Haithalkim, 5th and 20th April, 1884. The specimens agree tolerably closely with the figures by M . Lucas. 31. TERACOLUS SAXEUS. Teracolus saxeus, Swinhoe, P. Z. S. 1884, p. 441, pi. 40. figs. 1, 2. 8, Huswah, 14th March, 1884; 2, 9th September, 1883; $, Lahej, 9th September, 1883. Differs from the preceding in the subapical oblique orange band on the primaries below being of double the width, and in the much more pink colour of the under surface of the secondaries ; the female also is destitute of the oblique brown line near the inner edge of the broader orange apical patch. It is, of course, possible that the two may be dimorphic forms of one species, but this can only be satisfactorily decided by breeding. 32. TERACOLUS YERBURII. Teracolus yerburii, Swinhoe, P. Z. S. 1884, p. 441, pi. 39. fig. 12. Haithalkim, 4th and 5th April; Shaik Othman, 11th May, 1884. Occurs also at Lahej according to Major Yerbury. The species had evidently been some time on the wing when obtained, as only one of the six examples received was uninjured. 33. TERACOLUS SWINHOEI, sp. n. 8. Allied to the preceding species, from which it differs as follows :-Wings longer, the primaries with rounded apex and external angle, upper surface sulphur-yellow instead of milky white ; the black-brown apical patch of primaries more oblique, with the band of five orange spots decidedly narrower, more oblique, less angular, and with narrower blackish inner edge; secondaries with the grey basi-costal scaling continuous with the outer edge of the costal blackish spot, the apical patch unbroken ; the squamose grey band, from the apical patch to the submedian vein, further from the outer margin and paler than in T. yerburii; the black marginal spots much larger ; under surface tinted with sulphur-yellow throughout, bright sulphur-yellow over the basal half of the primaries and the external border, the subapical orange band much brighter and (as ou the upper surface) narrower and more oblique.
