a taxonomic separation. —2. In the elaboration of the very difficult group, VIIDALEPP (1976) made some mistakes of interpretation. With the exception of one specimen, all of his insects identified as bohatschi —at least those he sent to me —represent a hitherto undescribed species (= viidaleppi sp. n.); as for the exception, see the treatment of the next species. In his work, the figures purporting to represent bohatschi are referable to the new species (the males); nor is the figure of the male genitalia exact (and not even resembling those of bohatschi). And the figure displaying the female bursa copulatrix must have been made on the basis of an exemplar which, though standing near to bohatschi, is not this species nor the new one —or the figure represents an aberrative specimen of bohatschi or is fundamentally erroneous. 1 dedicate the new species to J. VIIDALEPP (Tartu, Estonia), excellent worker in the Geometridae, and in acknowledgement of the priceless material made available for study. 3. Eupithecia sachalini sp. n. (Fig. 17, 19) Diagnosis. A large-sized species within the bohatschi group. Alar expanse of the one known pair of specimens 19 mm. Wings wide, apex of fore wing rounded. Basic colour of fore wing brown with a violet sheen. Ante- and postmedian doubled, whitish stripes. Median section of basal field and anterior part of median field white. Discal spot black, marked. Terminal field dark, with a sharp zigzaggy submarginal line. Hind wing greyish white, transverse stripes densely arranged, grey, discal spot black. Underside of wings grey, pattern elements extraordinarily marked. Cilia medium long, shiny, striated yellowish grey and grey. Genitalia, çf : Uncus flat, valvae elongated saccus rounded. Aedoeagus thin, cylindrical, with a chitinous spine and another chitinous formation of irregular shape. Sternite VIII incised to its
