XI. Descriptions of new genera and species of Geode- 
phagous Coleoptera, from China. By H. W. 
Bates, F.L.S. 
[Read 17tli March, 1873.] 
The following descriptions, founded in great part on the 
collections made by Mr. George Lewis in China, are 
intended as a contribution to our knoAvledge of the Geode- 
phagous Fauna of that country, and as facilitating the 
comparison between the faunas of China and Japan in 
this department. It will have been observed that all 
species common to the two countries have been indicated 
in the foregoing memoir on the Geodcphaga of Japan. 
Cicindela Kaleea, Bates, Proc. Zool. See. 1866, p. 340. 
This species, described originally from the Island of 
Formosa, is found also in China. I have specimens from 
Shanghai, and Mr. Lewis has found it at Foochow. It 
varies considerably in size, in the relative length of the 
elytra, in colour and markings. Sometimes it is tinged 
above wdth a silky, tender green colour. The central 
oblique white band is dissolved in some examples into 
two spots, one discal and the other marginal, but there is 
almost always a trace of a slender line uniting the two. 
The species by its cylindiieal thorax and slender figure 
belongs to the same group as C. germanica, gracilis, &c.
