摘　　要：本文记述尤氏赤眼蜂属ＵｓｃａｎａＧｉｒａｕｌｔ及圆翅赤眼蜂属ＰｏｒｏｐｏｅａＦｏｅｒｓｔｅｒ中３新种：（１）粗腿尤氏赤眼蜂ＵｓｃａｎａｆｅｍｏｒａｌｉｓＬｏｕ新种；本种与豆象尤氏赤眼蜂Ｕ．ｃａｌｌｏｓｏｂｒｕｃｈｉＬｉｎ相似，但本种前翅缘毛明显较长，雌雄前翅最长缘毛分别为其翅宽的０．４及０．４４倍；翅面纤毛不如后种规则；雌虫产卵器较长，为后足胚节长的１．５倍；容易区别。（２）中国圆翅赤眼蜂ＰｏｒｏｐｏｅａｃｈｉｎｅｎｓｉｓＬｏｕ新种；本种前翅的缘前脉显著膨大呈结节状，雄虫触角末端３节紧密相连，接触面宽广、形成棒状节，雌虫棒节第１与第２节斜接并重迭等特征，可与本属所有已知种相区别。（３）榛卷象圆翅赤眼蜂ＰｏｒｏｐｏｅａｃｏｒｙｌｉＬｏｕ新种；本种雌虫触角棒节显著膨大，与Ｐ．ｍｉｎｋｉｅｗｉｃｚｉＮｏｗｉｃｋｉ相似，但后种前翅翅面上的纤毛明显稠密，而且有些纤毛排列不十分规则，两者易于区别。本种与Ｐ．ｄｅｆｅｌｉｐｐｉｉＳｉｌｖｅｓｔｒｉ亦较近似，区别在于后种的前翅翅面具２０列纤毛，雌虫触角棒节不特别膨大，稍定于第２索节。寄主：榛卷叶象甲Ａｐｏｄｅｒｕｓｃｏｒｙｌｉ（Ｌ．）和梨卷叶象甲Ｂｙｃｔｉｓｃｕｓｂｅｔｕｌ?One new species of Uscana Girault and two of Poropoea Foerster are described. (1)Uscana femoralis Lou, sp. nov.; similar to U. callosobruchi Lin, but for the new species,marginal cilia of forewing notably longer, and the longest ones 0.4 to 0.44 as long as the wing's width for the female and the male respectively. Discal cilia not so regular as the latter's. The ovipositor much long, 1.5 times of the lenghth or the hind tibia. (2) Poropoea chinensis Lou, sp. nov.; The forewing's premarginal vein widen obviously, nodiform; the apical three segments of the male's antennae, clavate, joint closely with a rather wide contact area.The female's antennal club, long -void, club Ⅰ and club Ⅱ connect slantingly with overlap. These are different from all the known species of the genus. (3) P. coryli Lou, sp. nov.; similar to P.minkiewiczi Nowicki in the widened antennal club of the female, but the latter's discal cilia of tthe forewing denser, and some not quite regular. This species is also allied to P. defelippit Sivestri, differs that the latterwith 20 rows of cilia on the forewing, and the female's antennal club not widen, slightly wider than funicle Ⅱ. The host is Apoderus coryli L. and Byctiscus betulae L.
