628. MiUochrista nigrivena, sp. n. 



Primaries crimson-pink, rather paler on discal area ; there are 

 three blackish dots on the basal area, one near the base, one above 

 the cell and one in the interno-interspace ; a larger black i?pot is 

 placed at the outer extremity of the cell, and the venation beyond is 

 streaked with black. Secondaries rather paler. Under surface pale 

 crimson-pink, the discal area of primaries strongly suffused with 

 blackish. 



Expanse 32 millim. 



One male specimen from Omei-shan, taken in June or 

 July.

629. Miltochi'ista Jlexioosa, sp. n. 



Primaries crimson-pink, paler on discal area ; the curved anti- 

 medial and very strongly denticulated post-medial lines blackish, 

 the latter followed by black spots opposite the extremity of each 

 tooth ; medial line waved and brownish ; just beyond this is a black 

 longitudinal line almost parallel with the costa, biit sharply angled 

 below the point of origin which is on the costa itself ; there are 

 some black marks on basal half of the wing and also in the outer 

 portion of the discal cell. All the markings are more or less sur- 

 rounded or bordered with pale yellowish. Secondaries same colour 

 as the discal area of primaries, outer margin crimson. Fringes 

 whitish. Under surface paler than above ; the primaries are clouded 

 with black on basal half of the costal area, and also on ihe venation 

 beyond the cell. 



Allied to M. nigrivena, but apart from differences on the upper 

 surfaces, the under surface of primaries is much less suffused with 

 black.
