This paper reports three new species of Agnini Thomson from China.All the type specimens are deposited in the Insect Collection,Southwest Agricultural University.1 Paraleprodera bimaculata sp.nov. (Figs.1 3) Length23?mm;breadth 7.5?mm. This species is related to P. insidiosa Pascoe,but can be distinguished from the latter by the lateral marking of elytron elliptical and rimmed with white pubescence instead of triangular shape;darkened on bases of elytra and decorated with white rhombus marking in front of lateral marking;and the paraproct provided with two baculi,converging each other at apex. Holotype ♀,Guan County (30°45′ N,103°25′E),Sichuan Province,Ⅷ.1957.The new species is named for its elytral character.2 Nanohammus yunnana sp.nov. (Figs.4 7) Length12?mm;breadth3 5?mm. This species is similar to N.itzingeri Breuning,but can be easily distinguished from the latter by lower lobe of eye longer than broad and deeper than gena below;scape expanded toward apex and third segment not so;pronotum without three longitudinal vittae;scutellum and elytra covered with grayish white pubescence instead of yellow pubescence and not formed a transverse band in middle;and antennal segments Ⅳ Ⅷ provided with a spine at apex. Holotype ♂,Monghai (alt. 1?500?m ,21°57′N,100°29′E),Yunnan Province, 8.Ⅴ.1980,coll.by LI Yun Min.Named for its type locality,Yunnan Province of China.3 Xenohammus albomaculata sp.nov. (Figs.8 12) Length 17 5?mm;breadth 5 0?mm. This new species is quite different from other known species of the genus by the color pattern in elytra:a grayish white marking in middle of elytron (usually provided with black marking in other known species of the genus). Holotype ♂,Hongya mujianggang(29°54′N,103°24′E),11.Ⅶ.1981,coll.by WANG Pu Jun.The specific name is derived from its main elytral character.
