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?
This article describes three new species of UscanaGirault and PoropoeaFoerster, Trichogramma: (1) a new species of UscanafemoralisLou, Tricholoma giganteus; CallosobruchiLin is similar, but this kind of forewing cilia is obviously longer, the longest cilia of the male and female forelimbs are respectively 0.4 and 0.44 times of their wings; the fin cilia is inferior to the latter kind of rules; the female ovipositor is longer, 1.5 times for hind leg embryo length; easy to distinguish. (2) A new species of PoropoeachinensisLou from China. The fore veins of this kind of forewing are obviously enlarged and nodular. The male antennal tip is closely connected with 3 nodes and the contact surface is wide, With the second section of the miter and overlap and other features, can be distinguished from all known species of this genus. (3) The new hazel coiled hawk-like PoropoeacoryliLou; the female femoris tentacles section was significantly enlarged, and P.. minkiewicziNowicki similar, but after the species of the front wing fin cilia obvious dense, and some cilia arranged not very rules, the two are easy to distinguish. This species and P. defelippii Silvestri is also more similar, the difference is that the latter species of winged winged mask 20 cilia, females tentacles section is not particularly swollen, slightly set in the second section.
