Show 1885.] LEPIDOPTERA FROM SOMALI-LAND. 771 This is an intergrade which I had not expected to see, combining the colouring on both surfaces of T. loandicus with the pattern of T. omphaloides. 39. TERACOLUS THRUPPI, sp. n. (Plate XLVII. fig. 10.) S • Allied to T. daira and T. yerburii, but the primaries in their markings more like T. sujfusus of Angola. Milk-white, costal border slightly greyish, the margin narrowly black; apical third to first median branch occupied by a black-brown triangular patch enclosing a lunate orange patch composed of six more or less elongated spots divided only by the black veins; outer margin towards external angle narrowly dusky ; a broad blackish internal band from base to external third, and widest in the middle; secondaries with the basi-costal third (excepting upon the abdominal area) blackish ; external border from submedian vein to apex broadly blackish, interrupted on the median and submedian interspaces by squamose white marginal spots; body black, tegulae with whitish and greyish fringe. Primaries below white, discoidal area sulphur-yellow, irrorated in front with grey ; a large and almost semicircular subapical orange patch, its inner border slightly sordid, bounded outwardly by a broad greenish external border which terminates on the first median interspace ; internal band broader than above, grey, becoming blackish at the outer extremity: secondaries white, the basicostal third pearl-grey suffused with pale sulphur-yellow, which gives it a greenish tint; basal half of costal margin deep orange ; a dusky oblique costal dash terminating the basicostal area ; a small fusiform orange spot dotted with black at the end of the cell ; external border pale yellowish, bounded internally by an unequal diffused olive-brownish band : body below white. Expanse of wings 36 millim. 2 • Primaries narrower, more rounded, the subapical patch replaced by a very oblique orange band composed of four elliptical sections separated only by the veins, and bounded internally by a narrow line of black, so that the apical area is decidedly smaller and its inner edge has a more defined angle than in the male ; fringe white instead of black ; internal blackish band of nearly equal width throughout: secondaries much shorter, with six unequal black marginal spots, the second and third large and followed by a grey submarginal band, so as to enclose four reniform pale yellowish spots between the black marginal spots: under surface yellower, the olive greenish apical area of primaries replaced by pale sulphur-yellow sparsely irrorated with grey, the orange band narrower, clearer in colour and more oblique, the secondaries sulphur-tinted throughout, with the basal area irrorated with grey, the discocellular spot better defined, and the submarginal band grey instead of olive-brownish. Expanse of wings 31 millim. One male, two females, January 2nd.- Thrupp. 40. TERACOLUS JAMESI, sp. n. 2 . Allied to T.phlegetonia, T. minans, T.interruptus, and T.friga; but at once distinguished by its smaller size, the absence of a black |
