Based on the determined specimens deposited in the Hebei University Museum, and the related data from the literatures, 1338 species of 626 genera, 51 families, 2 suborders of Coleoptera are known from Hebei - Beijing - Tianjin of China. Hereinto, the suborder Adephaga included 5 families (9. 80% ), 66 genera ( 10. 54% ), 188 species ( 14. 05% ), and the suborder Polyphaga included 46 families (90.20%), 560 genera (89.46%), 1150 species (85.95%). Data analyses show that the diversities of Polyphaga in the family, generic and specific levels are highest, the top 10 of family category are 275 species (20.55%) of 109 genera ( 17.41% ) of Chrysomelidae 〉 186 species (13.90%) of 99 genera (15.81%) of Cerambycidae 〉 167 species (12.48%) of 63 genera (0. 06% ) of Scarabaeidae 〉 138 species ( 10. 31% ) of 40 genera (6. 39% ) of Carabidae 〉 84 species (6. 28% ) of 48 genera (7.67%) of Curculionidae 〉 65 species (4.86%) of 30 genera (4.79%) of Coccinellidae 〉 45 species (3.36%) of 25 genera (3.99%) of Tenebrionidae 〉 41 species (3.06%) of 23 genera (3.67%) of Staphylinidae 〉 39 species (2.91%) of 20 genera (3.19%) of Dytiscidae 〉 32 species (2.39%) of 12 genera (1.92%) of Silphidae. The data indicate that there are 5 (9.80%) monotypic families, 22 (43.14%) oligotypic families and 24 (47.06%) polytypic families in the familial levels; 364 (58.15%) monotypic genera, 226 (36. 10% ) oligotypic genera and 36 (5.75%) polytypic genera in the generic levels. Besides, the result also show that the relation of Beetles' quantity and geographical area in China: 457 (73.00%) common genera in the Palaearctic and Oriental Realms, 626 ( 100.00% ) genera in the Northeast subrealm 〉 472 (75.40%) genera in the Central Asian subrealm 〉 457 (73.00%) genera in the Indo- China subrealm; North China Region (626 genera, 100.00% ) 〉 Mongolo - Xinjiang Region (472 genera, 75.40% ) 〉 Mid - China Region (457 genera, 73.00% ) 〉 North - east Region (357 genera, 57.03% ) 〉 Qinghai - Xizang Region (327 genera, 52. 24% ) 〉 South - west Region (302 genera, 48.24% ) 〉 South China Region (254 genera, 40.58% ), these include 163 (26.04%) endemic genera of North China; The quantity of Beetles in geographical distribution is Plain Area (73.80%) 〉 Taihang Mountain Area (65.81%) 〉Yan Mountains Area (50. 80%) 〉Basins Area (42. 33% ) 〉Plateau Area (38.98%).
