with rather strongly and evenly rounded sides, base much 

 wider than apex ; with scattered punctures of moderate size. 

 ]£lytra with irregular rows of rather small and distant punc- 

 tures, becoming smaller and more distant posteriorly, and 

 larger and denser (but not very dense) just behind the 

 shoulders ; apical slope with subsutural stria only distinct, but 

 with feeble remnants of others. Flanks of 'prosternum without 

 punctures, and without striation on most or all of the surface. 

 Fifth segment of abdomen with a small distinct fovea. Femora 

 edentate ; tibiae conspicuously ridged, regularly increasing in 

 width to apex ; basal joint of four front tarsi distinctly inflated, 

 licngth, 3J-6 mm. 



9 . Differs in having the abdomen more convex, without 

 iovea, tibiae somewhat thinner, and in the tarsi.

The comparatively sparse prothoracic punctures render 

 it certain that this species is not inermis, ccanthopus, australisy 

 rufimanus, or haroldi, the flanks of the prosternum with neither 

 conspicuous striae nor punctures also readily distinguish it 

 from those species,, and the hind tibiae of the male are con- 

 spicuously different from those of the species that appear to 

 be inermis. It is an abundant species, very variable in colour 

 and size, but readily distinguished by the prosternum and 

 tibiae. The commonest form of the species has the elytra more 

 •or less purplish, with the head, prothorax (the margins usually 

 excepted), and under-surface brassy-green or bluish, and the 

 labrum, front of clypeus, and the appendages more or less 

 reddish, but with part of the antennae infuscated. But the 

 elytra are frequently brassy at the sides, or entirely brassy, 

 or brassy-green, or steel-blue, or bronzy ; the head and pro- 

 thorax nearly always have a greenish or brassy-green gloss, 

 except that the margins are usually violet or deep-blue ; but 

 even when conspicuously green they frequently have a purplish 

 gloss in places. Sometimes only the apical joint of antennae 

 is infuscated, and sometimes only the five basal joints are 

 entirely pale ; usually the tip of the abdomen is obscurely 

 diluted with red ; the legs are occasionally deeply infuscated, 

 the tarsi less noticeably so than the other parts. On many 

 specimens the flanks of the prosternum are entirely non- 

 striated ; but on others striae are visible on the sides from 

 about the middle to the base ; they are usually rather distinct, 

 but vary through various degrees of intensity till they alto- 

 gether vanish ; punctures, however, appear to be always absent, 

 "but on the episterna they are numerous, but the episterna 

 themselves, being separated by deep sutures from the flanks,
