Distribution. China (Beijing, Heilongjiang, Jilin, Liaoning, Neimenggu, Hebei, Shandong (new record), Henan, Shaanxi, Gansu, Qinghai, Xinjiang, Anhui, Zhejiang, Hubei, Guangdong, Sichuan, Guizhou), Mongolia, Russia, N. Korea, S. Korea, Japan, Kazakhstan; Northern Europe.

Remarks. According to our research on a big series of specimens from Beijing, we believe that there is only one species distributed in Beijing and the north part of China, which was identified as M. (M.) myops ( Dalman, 1817) .

There are some specimens identical to M. (M.) stictica Blanchard, 1871 because of the anterior black spots on pronotum stouter and rounder, such as the Fig. 14 with a label of Mesosa stictica stictica Blanchard , and Fig. 15 with the pronotal spots much rounder than Fig. 12 . And such identification may be correct since they are quite similar to the holotype of M. (M.) stictica Blanchard, 1871 , which can be seen from the website http://bezbycids.com/byciddb/wdetails.asp?id=31677&w=o.

However, we decided to identify all of the Beijing specimens as the same species because those individuals with

“rounder spots” occur together with typical M. myops , sometimes collected from the same tree at the same time, and there are transitional forms between the typical slender spots and round spots, such as in Fig. 11 . It is very possible that Mesosa stictica Blanchard, 1871 is a variation of M. (M.) myops ( Dalman, 1817) . For further study, a review of their systematics,

based on examination of additional material including type material, should be done.
