I suppose that in due course I shall acquire much los and honour and not a little fame for harping in season and out of season to the tune of “Waterbugs.” But I shall feel that my labours have not been in vain if by so doing I can induce others to lauch themselves on the study of theese forms, which are in many respects the most interesting and easily observed and collected of the Heteroptera. In these families much remains to be done.
