AMBLTPODIA GROUP OP THE LYGENID^. 57 



central areas, extending right into the inner margin in the primaries ; this patch 

 in the secondaries is larger in extent, extending further towards the posterior margin. 

 Underside precisely as in male. 



This very lovely species forms a natural connecting-link, by its underside pattern, 

 between bazaloides Hew. and the most beautiful (though not the largest in size) 

 subgroup of the genus. From bazaloides Hew. it is immediately separable by its 

 gorgeous colouring above, whilst below the pattern, though similar in character, 

 is equally distinct in the very marked contrast of almost pure white and very dark 

 brown. I have specimens from Mindanao as well as from Mindoro, so we may expect 

 it to occur in other islands of the Philippine group. The genitalia are very distinct ; 

 the tegumen is not a hood, but is open at the top, and the laterals are small, the side 

 supports being ample ; the hooks are double-jointed, with the terminal arm sharply 

 bent at the elbow ; the clasps are curved and rather small, whilst the penis is long, 

 slender, horn-shaped, with a trumpet-shaped orifice.

I have, through my friend Dr. Staudinger's kindness, his two types of this most 

 unusual and lovely insect. The best description of the colour of the male is to call it 

 mother-of-pearl, for it quite shows the greenish and mauve translucent tints of that 

 material. It is at once separable from all other species by this colour. Mr. Grose- 

 Smith has since described it from South Celebes, so that it occurs both in the north 

 and south of that island.

Hab. Sangir. 



Expanse, 6 , 44 mm. 



This unique and beautiful little insect has only been recorded from the one island. 

 It should be recognised at a glance whenever found.
