A new species of Holmgren with a key to species known from China and the Eastern Palaearctic Region (Hymenoptera, Ichneumonidae, Poemeniinae).

A new species of Poemeniinae, Sun & Sheng, , is described and illustrated. Specimens were reared from twigs of Blume in Haicheng, Liaoning province, P.R.

[Dynamic changes of soil moisture in loess hilly and gully region under effects of different yearly precipitation patterns].

Based on field determinations, the dynamic changes of soil moisture in dry farmland, Robinia pseudoacacia forestland, Hippophae shrubland and Bothriochloa ischaemum grassland in loess hilly and gully region under effects of different yearly precipitation patterns were analyzed. The results showed that yearly precipitation pattern had definite effects on the seasonal variation and profile distribution of soil moisture. In normal year, soil moisture in dry farmland had a gentle seasonal variation; in dry year, it decreased slowly before rainy season but increased markedly after rainy season; while in rainy year, it had an overall increase and the increment was remarkable after rainy season.
