1896.] FROM NYASA-LAND. 837 
somewhat worn example of the South-African 7’. speciosus, to 
which it approaches much more closely than to any other violet- 
tipped Zeracolus: 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, worthy of consideration 
that Dr. Boisduval, who (in the Prerine especially) was apt to cut 
species very fine indeed, regarded the southern insect as typical 
7’. 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. Trimen 
includes 7’. jalone in the synonymy of his 7. tone and says that he 
does not consider it to be even a marked variety. Now 1. jalone 
has a conspicuous discocellular spot on the primaries, and its wet- 
season form has no more ray on the under surface than exists in 
7’. 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. Trimen gives “ White 
Nile” as the locality of my type of 7. jalone, and that certainly 
was the locality on the specimen. Should not this have suggested 
to him the possibility of 7’. jalone being the dry-season male of 
T’. phlegyas, rather than a hardly separable variation of 7’. imperator ? 
We certainly have one or two specimens which tend to link 
T. phlegyas 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 7’ jalone.

A dry-season form of this species, which cannot easily be 
confounded with any form of 7’. anne, but must stand between 
the latter and 7’. ewpompe. 
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.anne, var. wallengreni, but the marginal spots are too small, the 
colouring below too yellow, and the scarlet above too pronounced.
