AMBLTPODIA GROUP OF THE LYCJENHXE. 31 



shading ; above the anal angle the lobe-spot is black, edged above with a green 

 iridescence, which is extended up to the second median nervule, and underneath 

 which black spots show through the green scaling. The margin has a very fine grey 

 border at the anal area. Tail brown, tipped with white. 



? . Upperside : blue rather brighter than in male, extended almost all over both 

 wings; primaries have the costa blackish beyond the costal nervure; the apical area is 

 broadly black, narrowing to quite a moderate border both towards the costal vein and 

 the anal angle ; in the secondaries the blackish costal margin is broad, the posterior 

 margin is rather narrow, increasing a little at the anal angle ; the whole of the 

 abdominal fold up to the submedian nervure is brown. 



This is another species that appears to have been unobserved and unrecorded since 

 its description by the Bros. Felder. When examining the Felder Collection in the 

 Tring Museum I found the unique type, and recognised it as close to some specimens 

 in Staudinger's and my own collections, and I find they are identical. I have before 

 me one female (coll. Staudinger) from Halmaheira, which I make the type female, as 

 it corresponds with Felder' s type; I have also five males and one female from 

 Batchian. 



From meander Boisd. it may be recognized by the uniform brown colour of the 

 under surface, and by the transverse band of the primaries being narrower at the costa 

 than at its termination. 



I cannot really separate periander Grose-Smith from this species. 



The genitalia have a most ample tegumen ; as usual in this genus, the clasps are 

 distinct, somewhat fan-shaped, but more extended on one side. The penis has a 

 somewhat boat-shaped orifice, as will be seen in figure 7 a.

This species is a close ally of 'philander Feld., scarcely differing from it, the one 

 distinction being that in Felder's species the transverse band near the posterior margin 

 of the primaries is straight, whereas in the present species it is broken at the upper 

 median nervule.
