We selected 11 representative species of Mylabris Fabricius from China, analyzed and compared their hindwings, and described their morphological characteristics by taking M. calida Pallas, 1782 as the mode. As a result, the venations of Mylabris Fabricius were tentatively classified into three types as follows: Southern type, represented by Oriental species, wing dark brown with a lot of folds, veins stout and highly sclerotic; Plateau type, represented by Qingzang Plateau endemic species, wing ivorywhite and semitransparent, only the large cell enclosed by costal margin and MP₁₊₂ obvious; and Northern type, as the transition between the former two types, represented by Palearctic species, wing brown, veins clear and moderately sclerotic. At last, the vein morphological evolution of the genus was discussed.
