frequently with a white clot on the hinder angle; elytra rugosely punctured, 

 each with five ochreous spots, placed very obliquely in pairs, and forming on 

 both elytra a cross ; breast pilose ; abdomen nearly glabrous ; in the male 

 with a small yellowish spot on the side of each segment, and a larger one on 

 the last; this sex has also the intermediate tibia; curved at the base ; and 

 the female has the apex of the abdomen bituberculated. 



Usually found in decayed oak trees; rare near London; two 

 specimens having been taken on Peng-e Common, in 1806, and 

 two others in a lane near Brixton, about ten years subsequently. 

 It is, however, found annually in some plenty near Windsor, by 

 Messrs. Griesbach, to whom 1 am indebted for part of my series.

Shining-green, or coppery-gold colour ; clypeus broad, punctate : thorax thickly 

 rugose-punctate, with an obsolete dorsal furrow, and a white spot at the hinder 

 angle on each side ; elytra transversely rugose, with scattered white spots ; 

 abdomen cupreous, with white spots on the margin and on the upper ex- 

 posed surface ; breast clothed with reddish hairs. Male with curved inter- 

 mediate tibiae. 



In some examples the white spots on the elytra are evanescent. 



Somewhat local, but found in several places within the metro- 

 politan district; usually upon umbelliferous flowers: I have taken 

 it at Darenth, Birch, and Coombe-woods. " Greenhithe-wood."

This and the foregoing, with some continental species, form the 

 genus Gnorimus, St. Fargeau.

 the base, slightly pilose, the capitulum ovate. Palpi, with the terminal 



* Acanthurus of Kirby, employed in page 229, I find was long since applied 

 to a genus of fishes by La Cepede; it therefore becomes necessary to adopt 

 another term, and as the insect which forms the type of the genus has been 

 designated by the name above given in the last volume of the Encyclop.'die 

 Methodique, I have here continued it, in order to avoid the inevitable confusion 

 arising from the use of the same name in different classes of nature.
