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. suffusus of Angola. jNIilk-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, tegulse with whitish and greyish fringe. Pri- 

 maries 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 inter- 

 space ; 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 fusi- 

 form 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. 



$ . Primaries narrower, more rounded, the subapical patch re- 

 placed by a very oblique orange band composed of four elliptical 

 sections separated only by the veins, and bounded internally by a 

 narrow Hne 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 baud 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 obhque, 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-browuish. 

 Expanse of wings 31 millim. 



One male, two females, January 2\xdi.—Thrupp. 



40. Teracolus jamesi, sp. n. 



$ . Allied to T.phlegetonia, T. minans, T. mtemiptus, and T.friga; 

 but at once distinguished by its smaller size, the absence of a black
