of New PJiytophaga. 623 



antennis extrorsum verticeque nigris ; elytris distincte punc- 

 tatis, cupreis ; metasterno abdominisque basi piceis. 



Long. 3 lin. 



Hab. Sydney. Collected by Mr, Lowne. 



Head very short, epistome transverse, triangular, separated 

 froni the face by a grooved line, from the apex of which a deep 

 impression extends upwards on the face, surface of forehead irre- 

 gular ; antennae rather longer than the thorax, subfiliforra. Thorax 

 short, transverse, more than three times as broad as long, sides 

 rounded and narrowed from base to apex ; surface slightly im- 

 pressed with three or four irregular ill-defined foveas, general 

 surface finely punctured. Elytra impressed with deep and dis- 

 tinct but not large punctures, placed irregularly over the whole 

 surface ; humeral callus slightly thickened, bounded within by a 

 shallow groove, lateral border moderately dilated, separated from 

 the disc by a shallow depression. 



This species, collected by Mr. Lowne in the neighbourhood of 

 Sydney, is, I believe, the first Plagiodera received from Australia ; 

 the insects belonging to this genus have a very extensive range, 

 being found more or less abundantly in all quarters of the globe. 



Genus Adorium, Fabr. 

 1. Adorium Bowringil. 

 Ovatum, convexum, pallide flavum, nitidum ; tarsis, tibiarura 

 apice, antennarumque articulis ultimis quatuor, nigris ; ely- 

 tris caeruleis, albo-flavo limbatis (limbo basali fere obsoleto). 

 Long. 6 lin. 

 Hab. Hong Kong. 



Ovate, very convex, pale flavous, nitidous ; antennae robust, 

 filiform, four-fifths the length of the body, four apical joints black. 

 Thorax transverse, sides broadly rounded at the base, obliquely 

 narrowed towards their apex. Scutellum trigonate, its apex 

 rounded. Elytra distinctly but finely punctured, bright metallic 

 blue, each elytron bordered by a band of pale yellowish-white, 

 which is however interrupted and nearly obsolete on the basal 

 margin. Extreme apex of the tibiae, together with the tarsi, 

 black. 



This lovely species, perhaps the most beautiful in the genus, is 

 distinguished readily from its congeners by its peculiar colouring.
