摘　　要：双翅目(Diptera)短角亚目(Brachycera)的蜂虻科(Bombyliidae)昆虫常见于草原和田间,访花吸蜜,有助于植物授粉。蜂虻的幼虫多为捕食性或寄生性,蜂虻亚科(Bombyliinae)的雏蜂虻属(Anastoechus Osten—Saeken)昆虫主要在蝗虫的卵袋内寄食,庸蜂虹亚科(Exoprasopinae)的绒蜂虹属(Villa Lioy)昆虫主要寄生于夜蛾科幼虫,少数为鞘翅目的天敌。这两个属的蜂虻主要分布在古北区,体均粗壮而密生长毛,但从亚科的特征,特别是头部形态容易区分,绒蜂虻属的头近球形,后头极发达。In the present paper,. two new species of the genus Anastoechus Osten-Sacken and a new species of the genus Villa Lioy from Nei Mongol are described. The species Anastoechus nigricirratus-asiatius Becker is described as new to China. The type specimens are deposited in the Insect Collections of Beijng Agricultural University.1. Anastoechus aurecrnitus Du et Yang, sp. nov. (Fig. 1)The new species resembles A. nigricirratus Becker, but there are no red triangular spots on each side of the middle line of the scutellum as the latter species.Holotype (?) , allotype (?) , Nei Mongol: Taibus B., 16-Ⅷ-1978, coll. Yan Daping; paratypes 1 (?), same date as the holotype , coll Chen Heming; 1 (?), Beijing, 10-Ⅷ-1947, coll Yang Chi-kun.2. Anastoechus neimongolanus Du et Yang, sp. nov. (Figs. 2-3)This species is very similar to A. nigricirratus Becker from Transcaspia, but can be seperat-ed by the entirely black scutellum; and resembles the previously noted new sepcies (A. aurecrinetus) too, but differs from it by having totally white hairs (not golden).Holotype (?) , allotype (?) , Nei Mongol: Taibus B., 16-Ⅷ-1978, coll. Yan Daping; paratypes: 1 (?), 1 (?) , as holotype, coll. Chen Heming; 1 (?) , 1 (?) , Zhengxiangbai B., 14-Ⅷ-1978. coll. Yang Chi-kun; 1 (?) , Qahar Right Wing Middle B., Datan. 5-Ⅷ-1978, coll. Yang Chi-kun.3. Villa aurepilosa Du et Yang, sp. nov. (Figs. 5-6)This species resembles V. circudata Meigen, but the latter has a transverse stripe of white scales on anterior margins of Ⅱ-Ⅳ tergite; the male genitalia of the new species is similar to V. hottentotta L., but the latter has transverse stripe of light scales on Ⅱ-Ⅳ tergite.Holotype (?) , Liaoniag: Shenyang, 5-Ⅷ-986, coll. Lu Mingxian; paratype 1 (?) , Nei Mongol: Hailar C., 23-Ⅷ-1986, coll. Li Fasheng.
