The types are deposited in the Health and Anti-epidemic Station of Benxi, Liaoning Province.1. Helina rastrella sp. nov. (Figs. 1-3)Male: This species resembles Helina setiventris Eingd., 1924, especially in male terminalia, but the fore tibia with posterior bristle; dorsocentral bristles 2+3; length of 4th sternite longer than its width.It somewhat resembles Helina allotalla (Meigen, 1830), but differs from the latter in the width of frons in male being rather narrow.2. Helina fica sp. nov. (Figs. 4-6)Male: Prealar bristle as long as the posterior notopleural bristle; cross-vein brown, not suffused; fore tibia with a posterior bristle, distal part of hind femur without pos-terioventral bristles, posterior setae of hind tibia on the distal half, scutellum only with fine hairs on the lateral edges of ventral surface. By these characters, it may be readily distinguished from the allied species, Helina laetifica (E.-D., 1830).
