thcrnm. R. mesotherma Hamps. (6 a) is to be placed behind albula Schiff. (Vol. 2, p. 45, pi. 10 c). Bodv white 
legs brownish. Forewings white, peppered with brown in basal costal area and in middle of margin, ochreous 
in discai area with exception of patch at inner margin which is peppered with darker brown; in middle of costal 
margin an ochre-brown spot with white edge; transverse lines ochreous brown, as is the inner ed°e of the white 
subterminal line. The white hindwings faintly clouded. Central China (Chungking).

winch differs from Roeselia_ through vein 10 arising free from cell of forewings. In order not to introduce a 
uithei Genus, the species is retained here; it should be placed behind strigula Schiff. (Vol. 2, p. 46). Body 
grey-white admixed with brown. Forewings pale grey, peppered with darker scales; transverse lines blackish

appressions of scales; a blackish streak in centre of costa, from lower end of cell an undulate line continuing 
to inner margin; a dark subterminal line is indicated. The white hindwings dusted with brown Central China
