  • Factorial experiments are studied in this paper. The Designs, thus, have factorial balance with respect to estimable main effects and interactions. John and Lewis (1983) considered generalized cyclic row-column designs for factorial experiments. A simple method of constructing confounded designs using the classical method of confounding for block designs is described in this paper.

  • A new species, Tritoma gangwonensis sp. nov., is described. Also three species - Rhodotritoma fitlva (Reitter, 1879), Triplax discicollis Lewis, 1887 and Triplax signaticollis Reitter, 1879 - are reported for the first time in Korea. A description and redescriptions for each species, photographs of adults and illustrations of diagnostic characters are provided.
