A key to Chinese known species,redescriptions,and illustrations,especially S7,S8 and gonostyli of males are provided.

A New Species of Menida Motschulsky from China with a Redescription of Menida salvazana Distant (Hemiptera:Pentatomidae);

The redescriptions and main life habits of Eurytoma samsonowi Wassiliew 1915 and Eurytoma maslovskii Nikolskaya 1945,boring into the fruits of Prunus spp in China,are reported.

In the paper,the author studies the performance of specific implementations of layered coding and multiple description coding for video streaming over IP networks,and compares their performances using different transmission schemes under the condition of network and without network path diversity by recording their signal-to-noise ratio.

In this paper, a source coding technique exploiting packet path diversity is presented, which combines the individual benefits of MDC (multiple description coding) and LC (layer coding) for video transmission over wireless networks.

The method of Layered multiple description coding(MDC) for real-time video transmission is introduced by combining multiple description coding with Layered transmission technology in this paper.
