Eigth new species of the genus Blaps Fabricius, 1775 (Coleoptera: Tenebrionidae: Blaptini) from China are described in this paper, namely: Blaps garzica , sp. nov., Blaps furcala , sp. nov., B. taiyuanica , sp. nov., B. acutangula , sp. nov., B. choui , sp. nov., B. pilosa , sp. nov., B. brevis , sp. nov. and B. ratalaria , sp. nov.. The type specimens are preserved in the Museum of Hebei University. 1. Blaps garzica, sp. nov. (Fig.1) Length: ♂ 25 mm, width: 10 mm. The new species is closely related to Blaps japonensis Marseul, 1879, but differs from the latter as follows: 1) both sides of pronotum almost parallel to each other rather than arched; 2) elytral basis without strong constriction: 3) transverse wrinkles on the middle part of first sternite coarse rather than fine and vague; 4) the ratio of the length to width of paramera being 1.25∶1 instead of 2.25∶1. Holotyp: ♂, Sichuan (Garze County), 09 Ⅳ 1973, Li Jijun. 2. Blaps furcala, sp. nov. (Fig.2) Length: ♀ 32.5 mm, width: 14.5 mm. The new species is closely related to B. gobiensis (Frivaldsky, 1889), but can be separated from the latter as below: 1) anterior margin of labrum concave deeply, rather than a shallowly concave; 2) mentum inverted trapezoid in shape instead of elliptical shaped; 3) end of prosternal process sharp rather than straight; 4) elytral mucro horizontal and its end forked, but in the latter curved downward and not forked. Holotype: ♀, Inner Mongolia (Alxa Right Banner), 20 Ⅶ 1988, Ren Guodong. 3. Blaps taiyuanica, sp. nov. (Fig.3) Length: ♂ 23 mm～25 mm, ♀ 23 mm; width: ♂ 8 mm～9 mm, ♀ 10.5 mm. The new species is similar to Blapsrugosa Gebler, 1825, but can be distinguished from the latter by following characters: 1) body larger, longer than 22 mm; 2) elytral mucro slightly forked, 2 mm long in male and 1.5 mm long in female; but in the latter only 1 mm long in male, and indistinct or even absent in female; 3) the ratio of length to width of p
