but in tlie secondaries extends from about vein 2 to vein 7 ; 

 there is a trace of a marginal series of black points in both 

 wings which is definite in the secondaries ; a large black 

 subapical spot is present also in the secondaries. The fringes 

 of the primaries are brownish, in the secondaries they are 

 white, with a black dot at the end of each vein.

Hah. Urai, North Formosa. 



Type in my collection. 



This species, whicli was brought home by Mr. Elwes, and 

 of which specimens are now in the National Collection, is 

 very close indeed to marice, but it has a greater extent of 

 blue above ; so close did il: appear to be (though there was 

 something that made me think it was distinct) that to be quite 

 sure about it I mounted the male sexual armature of both, 

 from which it became evident that they were distinct species; 

 the clasps and the jedeagus are very different in shape, and 

 the tegumen likewise shows definite distinctions. 



Walgeum mioswara, sp. n. 



Primaries dark brown, with a broad white band running 

 along the lower margin of the cell and halfway along vein 4, 

 the outer border being indefinite ; on the cell are a few 

 scattered brilliant metallic-blue scales. Secondaries dark 

 brown, with a broad white band across the base of the wing 

 from the inner margin to near the apex of the costa. Under- 

 side: primaries with the white band more extensive and 

 whiter ; an irregular, broadish, brilliant, metallic-blue costal 

 stripe, curved more narrowly round the black cellular and 

 upper radial area, and recurved basewards along vein 4 ; 

 a subterminal brilliant blue line, interrupted at the veins. 

 Secondaries with a black basal costal patch surrounded with 

 brilliant blue scales ; an oblique broad white band right 

 across the wing, edged by a brilliant blue line which borders 

 the deep black area extending up to the termen, and in which 

 is an oblique, broad, brilliant metallic-blue band, extending 

 from the inner margin to vein 6, at which point it is broadest 

 and has an evenly rounded termination ; a broadish terminal 

 line of brilliant blue.
