TEEACOLUS. 57 



"Drv-season " FORM 01' THE Male. — Smaller than that of T. iiuperator, with the 

 purple apical band and black markings narrower, the base of the primaries faintly 

 sprinkled with grey, the black nervules on the secondaries not so strongly indicated. 



Underside. — The primaries and secondaries are similar below to those of 2\ impe- 

 rator ; the transverse discal line on the latter nearly obsolete and the vermiculations 

 confined to the costal margin. Expanse 2 inches. {Spec. (•■r. Sahaki Valley ; 

 Dr. J. IF. Gregory ; Mas. Brit.). 



"Dry-season" form of the Female. — Similar to the "dry-season" form of 

 T. imperator, but differs in having no dark shading on the inner margin of the pri- 

 maries ; the black spot near the posterior angle much smaller. Secondaries similar 

 to those of T. imperator. 



Underside. — The general colour on both wings darker than in T. imperator ; the 

 secondaries thickly covered with light brown vermiculations ; the transverse discal 

 band broadly shaded with light brown on the inner aspect near the costal margin ; 

 the hind-marginal border deep russet yellow. Expanse 3-3 inches. {Spec. ex. 

 Mozambique, July I Dr. J. W. Ansorge ; Mus. Rothschild.)

Dr. Butler (/.c.) gives the following reasons for the separation of this form : 

 "This species at all seasons differs from the preceding in the extremely narrow 

 and much more glistening lilac apical patch or band on the primaries of the male, 

 its black inner edging almost or wholly wanting, and in the deep indentation or 

 complete separation of the internal black stripe on the primaries of the female ; the 

 latter sex is either white or yellow, the apical area being either crossed by an orange 

 patch or a row of white spots, as in T. imperator. The dry form of the male differs 

 chiefly from the wet form in the rosy colouring of the apex of the primaries and the 

 whole surface of the secondaries on the under surface, whilst extreme wet types of the 

 male are not only pearly white below, but show an oblique discal series of black spots 

 between the costal vein and second median branch on the underside of the secondaries ; 

 the female of the dry phase resembles the wet form of T. phhyyas on the upperside 

 and the dry form of that species on the underside ; it is, however, larger and shows 

 heavier black markings. Expanse of wings, S 58-71 millim., ? G2-(Ji) millim.
