allusion was there mado to the affinity of the two insects, 

 and the rich dark purple colour of the elytra of G. Mait- 

 landi was adduced as the distinguishing character between 

 it and the other allied species ; this character has, how- 

 ever, now proved to be abnormal. Count Mniszech having 

 lately received specimens of the same development which 

 have the elytra covered with the silken pubescence of 

 the var. minor {G.faunicolor, Hope). The name Mait- 

 landi is therefore to be sunk as a synonym.

Prismognathus subceneus and Metopodontus dauricus 

 were originally described as distinct species, and sub- 

 sequently indicated by the author as identical, and to be 

 united under the name of P. dauricus. In 1864', I received 

 from Mr. Bowring the S and $ of an insect from Chow- 

 san, which I considered new, and described under the 

 name of Cyclorasis Jekelii ; having since examined other 

 specimens in Count Mniszech^s collection, and also in 

 that of the Jardin des Plantes, received from Pekin and 

 Mantchouria, my attention has been drawn to the descrip- 

 tions and figures given by Col. Motschulsky, and I have 

 every reason to believe that the two are really identical. 

 One of the chief characters of the genus in which I had 

 placed it, ''^oculi rotundati,integri " is unnoticed by Mots- 

 chulsky, who characterizes it as being remarkable for the 

 prismatic colouring of the mandibles, which are also 

 strongly grooved on their upper surface, and furnished 

 with a sub-erect tooth near the apex. Although Mr. Thom- 

 son's name of Cyclorasis is undoubtedly more appropriate, 

 it must nevertheless, in right of priority, yield to Pris- 

 mognathus of Motschulsky ; the specific name of subceneus, 

 representing the male, ought however to be retained.
