 Long. 13-15 mm. ; lat. max. 8-9 mm. 



Hah. E. China, Tientsin. 



A considerable number of specimens were collected from 

 April to June 1906 by Mr. F. M, Thomson. 



It is nearly related to M. specularis, Ohaus, and M. vittaii- 

 coUis, Burm., and the colour is that of the latter except that 

 it is almost uniform above, only the clypeus, the lateral 

 margins of the prothorax, and the elytra being a shade lighter. 

 It is smaller than either of those species, and the curious 

 corrugation of the posterior part of the sides of the pro- 

 thorax distinguishes it at a glance from all. This corrugation 

 is variable in its extent, but is almost invariably a very 

 marked feature. The upper surface of the insect is strongly 

 and closely punctured, except the prothorax and scutellum, 

 of which the puncturation is fine. The pygidiura is coarsely 

 punctured and the sides of the body are thinly pubescent 

 beneath. The mesosternum is pointed, but not produced 

 beyond the coxse, and the front tibiae are bidentate in both 

 sexes. 



I printed in 1899 a few synonymical notes relating to 

 Mimela. To these I may add the following : — 



M. lucidula, Hope, and lathamt, Hope, belong to M. splen- 

 dens, Gyll. 



M. glabra, Hope, type, is a female of M. downesi, Hope. 



M. limhata, Burm., and M. ijomacea, Bates, are M. passe- 

 rinii, Hope, 



M. coxalis, Ohaus, is M. (" Anomala ") inscripta, Nonf. 



M. pyroscelis, Hope, is a species of Anomala.
