Ranges from Northern Australia northwards to Timor 

 Laut, Am, and New Guinea, and thence eastwards to New 

 Ireland, appearing just to touch the Solomons ; more to the 

 south it ranges eastwards to the Loyalty, New Hebrides, and 

 Fiji Islands. 



This species exhibits a more restricted variability than 

 T. suavcij which it doubtless replaces in Australasia ; the 

 mode of variation is, however, similar. Regarded as a whole 

 it is a smaller type, never so heavily bordered or suffused 

 with blackish as typical T. suava nor so narrowly bordered 

 as T. apicalis. 



The varieties with their seasonal forms are as follows : 



Yar. I. 



The wet-season form is T. photophila, with the outer border 

 slightly narrower in T. liebridina, the upper angle of the 

 sinus rounded off and the border of secondaries very narrow 

 or reduced to dots in T. inanata and aprica (the hitter is 

 larger than T. inanata and has the margin of secondaries 

 dotted). The intermediate form of this variety is unnamed. 

 The dry-season form is T. maroensisphcebuSj of which 

 T. sulphurata and variata are narrower bordered examples, 

 the latter small and with dotted margin to the secondaries. 



Var. 2. 



The outer border of primaries broad at apex, but narrow at 

 external angle ; the seasonal forms are unnamed.
