Mr. Butler was evidently mistaken in describing his species as 

 differing from T. cleotas, Guer., by the male having the purple 

 colour spread over the primaries and the centre of the secondaries. 

 As a matter of fact T. cleotas S has the purple of a lighter and 

 more brilliant hue, and much more extensively spread over both 

 wings, leaving the margins only narrowly black. Mr. Butler has 

 doubtless taken Guerin's figure for a male, whereas it is a female with 

 somewhat more blue than usual. M\ females I have seen from 

 New Ireland have this blue to a greater or lesser extent, but I note 

 that females of T. cleotas from the Solomon Islands are without it, 

 also all females of T. excellens. 



I think T. excellens can be distinguished by having the veins black, 

 and by the outer margin of primaries having a considerably broader 

 black border.

A common insect in these islands, and showing a good deal of 

 variation in the size of the ocelli below and also in the expanse of 

 wings, varying from 1^1^ inch. 



When I described this insect in 1887, examples stood in the 

 British Museum collection unnamed, as, although Mr. Butler 

 described it in 1883, the types were not incorporated and he had 

 forgotten that he had named it.

This species probably equals N. vitiensis, as it is described as 

 having on the hind wing large verdigris-coloured bordered round 

 spots of equal size, which at once distinguish it from Jamides can- 

 drena and its allies.
