Abstract: Taxa of V. variegata and its allied species are taxonomically perplexing.By means of conventional taxonomic methods, it is difficult to discriminate them from one another. A quantitative analysis of the correlations between certain key characters was thus made by applying the methods of pictorra-lized scatter diagram and histogram. Results from both methods have indicated that this complex can be divided into 3 parts:V. Te and Tr respec-tively. According to the pictorialized scatter diagram and histogram, V(V.varieeata Fisch.) can easily seperated from Te and Tr. It is thereforeadvisable to reserve the specific rank of this taxa. Te and Tr are somewhatover lapped and are by no means strictly separable. Thus we favor thetreatment made by W. Beck. in 1916 to treat Te as a distinct species, namely V. tenuicornis W. Beck. and Tr as a subspecies of V. tenuicornis, asV. tenuicornis ssp. trichosepala W. Beck.
