This curious insect is among the number of those lately brought from China. A 

 figure of the upper surface is represented on a leaf of the Camellia Sesanqua, one of the 

 vignette plates of Sir G. Staunton's History of the late Embassy to that country ; a 

 coloured figure and a short account of it may therefore prove acceptable to the readers of 

 his volumes. 



Stoll has also given a figure of it, and has also represented another sort, which he 

 considers as the female (letter A) ; it has no black points in the yellow spots of the 

 thorax and scutellum : he mentions the Isle of Formosa as the native country of his 

 specimens. 



Fabricius observes, that it varies according to the sex by having an acute spine on 

 each side of the thorax, as represented in the accompanying figures ; this statement is, 

 however, denied in the Encyclopedic Methodique, vol. x. p. 410, by Messrs. Saint Fargeau
