Material of the noxious specieswas demanded and after some months 7 specimen of a species of Locustidwere received, 636 and 1 512.After examinatioll of the locustids I cameto the conclusion that the specieswas again a Sexavabut another one as those mentioned by DR.

KARNY asked me to describe this new speciesand to publish this description, which I do herewith.I name this new species after DR. H.
