1896.] FROM NYASA-LAND. 837 



somewhat worn example of the South-African T. speciosus, to 

 which it approaches much more closely than to any other violet- 

 tipped Teracolus : it is the only known species which can be 

 accurately described as having the apical black border " divided 

 transversely and obliquely by a violet band, very brilliant, rounded 

 externally " : it is moreover, in my opinion, w r orthy of consideration 

 that Dr. Boisduval, who (in the Pierince especially) was apt to cut 

 species very fine indeed, regarded the southern insect as typical 

 T. ione, as there can be little doubt that the Doctor had examined 

 the original type. 



One fact, however, must not be lost sight of: Mr. Trimeri 

 includes T. jalone in the synonymy of his T. ione and says that he 

 does not consider it to be even a marked variety. Now T. jalone 

 has a conspicuous discoi'ellular spot on the primaries, and its wet- 

 season form has no more ray on the under surface than exists in 

 T. speciosus ; only the apical border is conspicuously dusted with 

 white scales, and the violet band is too close to the inner edge of 

 the coloured apical area to be correctly spoken of as an oblique 

 band crossing the border at apex. Mr. Triinen gives " White 

 Nile " as the locality of my type of T. jalone, and that certainly 

 was the locality on the specimen. Should not this have suggested 

 to him the possibility of T. jalone being the dry-season male of 

 T. phlegyas, rather than a hardly separable variation of T. imperator ? 

 We certainly have one or two specimens which tend to link 

 T. phleyyas and T. jalone ; and the two male examples taken on 

 March 9th represent the spotted and unspotted types, although 

 neither of them has the pink under surface with transverse ray of 

 the typical dry-season form T. jalone.

A dry-season form of this species, which cannot easily be 

 confounded with any form of T. annce, but must stand between 

 the latter and T. eupowpe. 



The dry-season form differs from the (typical) wet-season form 

 in its superior size, the scarlet instead of orange colouring and 

 greater width of the apical patch on the primaries, the greyer basal 

 area and the pinky yellowish apical area of primaries and ground- 

 colour of secondaries on the under surface ; the black terminations 

 to the nervures are also almost obliterated : it comes nearest to 

 T. annce, var. wallengreni, but the marginal spots are too small, the 

 colouring below too yellow, and the scarlet above too pronounced.
