All type specimens are deposited in the Department of Biology, Nankai University, Tianjin. Male genitalia and other features are illustrated (Figs.1-11). All measurements are in millimeters. These new species are briefly characterized below. Urochela albosignata sp. nov. (Figs.1-5) Body brown, eye red, external area of corium grass-green, antennae dark-brown, connexivum of abdomen yellowish. Length of male body 9.4, width 4.0. Length of antennal segmentsⅠ∶Ⅱ∶Ⅲ∶Ⅳ∶Ⅴ=1.9∶2.0∶1.2∶2.0∶1.8. Length of pronotum 1.9, width between lateral angles 3.8. Median process of pygophore rounded; paramere and aedeagus as shown in Figs. 1-3. The new species is closely related to Urochela flavoannulata (Stl) in appearance and size, but differs in having a brown body, two pale yellowish points on the median area of pronotum, each basal angle of scutellum with one white point and different genital structure. Holotype ♂, Yunnan Province, Simao (22.48°N, 100.58°E), 1?600?m, 16 May 2000, BU Wen-Jun leg.;paratypes 2♀♀, 1♂ same above; 2♀♀, Yunnan Province, Simao, 1?500?m, 27 May 2000, light trap, BU Wen-Jun leg. Etymology. Named for its pale yellowish points. Urolabida wufengana sp. nov. (Figs. 6-11) Body green, with black punctures. Body length of male 13.1, width of abdomen 4.7. head length 1.0, width 1.8. Length of antennal segments Ⅰ∶Ⅱ∶Ⅲ∶ Ⅳ∶Ⅴ=3.5∶3.6∶1.5∶3.1∶2.0. Length of pronotum 2.2, width between lateral angles 4.4. Length of hemelytron 10.0. Structure of male genitalia as shown in Figs.6-9, 11. This new species is allied to Urolabida scutellata Ren in body color and external outline of the male genitalia, but it can be easily distinguished
