discocellular dot on the primaries, the position of the nebulous grey 

 discal band on the secondaries, which is much further from the 

 outer margin, and the paler and more delicate colouring on both 

 surfaces. Its general aspect is that of T.frigu (P. Z. S. 1876, pi. vi. 

 fig. 5, 5 ) ; but, in addition to the absence of the discocellular dot, 

 the wings are whiter, the oblique subapical band is narrower, more 

 oblique than in the figure, bounded throughout with orange, the 

 outer border is more acutely dentated and terminates in a small 

 blnck spot ; the internal streak extends from the base, is grey 

 throughout ; the spot on the disk of secondaries is continued as a 

 streak tapering to the submedian vein, and the marginal border is 

 replaced by six blackish spots : on the under surface it is quite 

 different, being similar to, but much paler than, the female of 

 T. eione. Expanse of wings 28-33 millim. 



Two females. — Thrupp. 



There is not the least doubt that many Lepidopterists who did 

 not possess abundant material would have put down T. janiesi as 

 the female of T. thruppii, overlooking the differences between the 

 sexes of that species, and regarding them all as males ; yet there can 

 be no question that it belongs to a different subgroup, the males of 

 which invariably have a transverse blackish discal spot or dash upon 

 the orange apical area, as in T. friga, S (see figure in P. Z. S. 

 187fi); whereas the females of the T.-daira group nearly resemble 

 the males, both having the orange apical patch bounded internally 

 by a black line, stripe, or baud. 



41. Teracolus phillipsi, sp. n. (Plate XLVII. fig. 11.) 



Nearly allied to T. evarne. The male differing in its pure white 

 colour, smaller and less brilliant orange apical patch, with much 

 narrower sulphur-yellow edging, the very narrow black margin to 

 the primaries, absence of marginal spots in the secondaries ; pri- 

 maries below white instead of sulphur-yellow, the apical patch 

 sulphur-yellow, with pale pink inner edging instead of creamy 

 ochraceous, and with three well-defined subapical brown dots in an 

 oblique series : secondaries creamy white, shorter than in T. evajme, 

 with only the costa slightly yellowish. The female differs above in 

 its whiter colouring, much better-defined black markings, the sub- 

 apical spots forming a continuous irregular stripe, the much smaller 

 orange apical area, and the entirely different coloration of the under 

 surface, which closely resembles that of T. eucharis $ . Expanse 

 of wings, S 42 millim., $ 40 millim. 



One male and three females. — Thrupp. 



Var. a. Smaller ; the orange apical area of male narrower, with 

 concave rather thau convex inner edge, the black border reduced to 

 a few apical marginal dots ; under surface of primaries with the 

 subapical dots reduced to two, and orange instead of brown ; the 

 female altogether paler, with smaller black markings, the subapical 

 spots separate as in T. evarne $ , the apical area only irrorated 

 with orange, zo that it appears to be flesh-coloured ; the under 

 surface altogether whiter (but occasionally with pinkish secondaries),
