I have fully expected to receive a species linking T. miriam to the 

 T. halimede group for some years past ; when we receive the male of 

 T. coliagenes, I have no doubt it will prove to belong to the latter 

 group, perhaps tending to link it to T. abyssinicus, T. eris, and 

 T. maimuna. 



T. miriam of Aden has been refigured, as from Madagascar, by 

 M. Mabille under the new synonym of Anthocharis eucheria, 

 Anthocharis is an obsolete name for the European genus Euehloe, 

 which diifers from Teracolus in neuration iu having five subcostal 

 branches instead of four to the primaries, and in the position of the 

 upper radial, which is emitted from the inferior edge of the subcostal 

 vein beyond the cell ; these are points which prove Euehloe to be- 

 long to a different section of the subfamily from that to which 

 Teracolus belongs. 



The two forms of T. pleione, which scarcely differ and certainly 

 interbreed, have now been described four and figured three times.

Allied to T. amina, the male on the upper surface only differing 

 in the greater width of the blackish border and the absence of mar- 

 ginal spots, the female differing also in its yellower colour (the base 

 of the primaries and whole of secondaries up to the border being 

 yellow) ; the blackish apical half of primaries irrorated with carmine, 

 crossed by seven spots of this colour and with six marginal carmine 

 dots : under surface entirely distinct from T. amina, the primaries 

 with the basal three fifths of the discoidal cell cadmium-yellow, 

 shading into lemon-yellow towards the costa and vermilion towards 

 its outer extremity ; female also with a broad submedian streak of 

 vermilion, a round black spot at the end of the cell ; a central white 

 belt enclosing the black spot, beyond which the whole disk, with the 

 exception of a triangular apical patch, is bright rose-red and crossed 

 by an angular series of black spots ; apical patch yellow and quad- 

 rifid internally, dark ochraceous flesh-coloured externally : secon- 

 daries lemon-yellow, with the basi-abdominal area in the male 

 yellowish flesh-coloured, and in the female bright gamboge-yellow ; 

 the external area ochraceous flesh-coloured, bounded internally by 

 an angular lilacine brownish macular band enclosing a series of bright 

 yellow crescents : body below whitish. Expanse of wings, c? 43 

 milHm., $ 48 millim. 



One pair, the male taken by Mr. Thrupp and the female by Mr. 

 Lort-Phillips, who captured it with his.fingers whilst it was hovering 

 about the flowers of a Mimosa or similar shrub. 



This is one of the most distinct, beautiful, and at the same 

 time interesting species yet discovered. I have long been looking 

 for evidence that T. amina and T. celimene are intermediate (as 

 they appear to be) between the two groups to which the names
