The study was conducted to investigate the community structure of superfamily Coreoidea (Geocorisae: Hemiptera) in Mt. Kyeryongsan from August, 1989 to August, 1990. The collected coreoid insects were composed of 17 species, 13 genera, and 2 families. Percentages of coreoid insects found in each observed zone were 47.4% (13 species) in the paddy bank, 37.4 % (13 species) in the weedy field and 15.2% (11 species) in the shrubs. Dominant species and Simpson's dominance indices were Riptortus clavatusa and Stictopleurus crassicornis ($\lambda$=0.128) in the paddy field, Cletus schmidti and Homoeocerus dilatatus ($\lambda$=0.141) in the weedy field, Riptortus clavatus and Homoeocerus dilatatus ($\lambda$=0.199) in the shrubs. Seasonal dominant species were Cletus trigon us and Rhopalus maculatus ($\lambda$=0.149) in Spring, Cletus schmidti and Homoeocerus dilatatus ($\lambda$=0.132) in Summer, and Riptortus clavatus and Cletus schmidti ($\lambda$=0. 386) in Autumn. Species diversity indices(H') in the paddy bank, weedy field, and shrubs were 0.931, 0.916, and 0.810, respectively. Eveness indices(J') were 0.836, 0.800, and 0.778, respectively. Community structures were almost similar between the paddy bank and the weedy field.
