258 DR. A. G. BUTLER ON LEPIDOPTERA [Mar. 19, 



diffused internally but defined externally by a whitish irregularly 

 undulated stripe ; fringes with whitish basal and dark brown central 

 lines ; palpi below whitish. Expanse of wings 73-75 millim. 



Dry -season form $ . Smaller ; the angle of primaries less 

 produced below apex ; the secondaries with slightly larger and 

 brighter ocelli ; a small ocellus indicated on the first median inter- 

 space of the primaries : wings below olive-brown, the bands across 

 the primaries lilac, but the apical patch whiter ; three sharply defined 

 ocelli coloured as on the upper surface one small, on upper radial 

 interspace, a second large on lower median interspace, and the 

 third very small, below the second : secondaries with all the 

 whitish markings ill-defined, but both ocelli clearly defined. 

 Expanse of wings 66 millirn. 



Ewambo. 



Four typical specimens and two females of the supposed dry- 

 season form were obtained. It is, without question, by far the 

 most beautiful Junonia hitherto discovered. 



Whilst deprecating the positive way in which Lepidopterists 

 have, of late years, decided (without breeding in most instances) 

 respecting the seasonal forms of Butterflies, I do not for a moment 

 pretend to say that their conclusions are unlikely, in most instances, 

 to prove correct. In the present case the two forms of female, 

 though very different in aspect, are so evidently only modifications 

 of the same species that it is but reasonable to conjecture that the 

 smaller form with prominent ocelli is that of the dry-season.

One example of this rare species. Is it the dry-season form of 

 J. artaxia ?

The whole of the specimens are very dark, larger than usual, 



and with the red ocellated belt narrower and slightly darker than 



in the majority of specimens ; the under-surface colouring varies 



individually to an enormous extent, two examples exactly represent
