margin oblique on either side, slightly sinuate on each 

 side the medial lobe, the latter obtusely rounded ; upper 

 surface shining, obscure rufous, narrowly edged with 

 piceous, middle of disk remotely punctured. Scutellum 

 semiovate. Elytra strongly but not closely punctured, 

 the punctures arranged in longitudinal rows on the sides 

 and towards the apex, less regularly placed on the inner 

 disk, interspaces plane. The colouring of the under 

 surface varies in intensity in different individuals, in some 

 specimens the legs and apex of abdomen being rufo- 

 piceous.

Rotundatus, valde convexus, nitidus, subtus niger, ab- 

 dominis apice pedibusque rufis ; supra metallico-coeruleus, 

 capite rufo, vertice cyaneo tincto, antennis pallide fuhas ; 

 thorace sat fortiter, minus remote puuctato ; elytris fortiter

Hab. — Amazons ; collected by Mr. Bates. 



Head rather coarsely punctured; clypeus ill-defined, its 

 anterior margin obsoletely bidentate ; antenna scarcely 

 more than half the length of the body, slender, filiform, 

 pale fulvous, the apical joints stained with piceous. Thorax 

 nearly three times as broad as long at the base ; sides 

 rounded and converging from base to apex, the anterior 

 angles acute, slightly recurved, the hinder ones subacute ; 

 the basal border distinctly margined, oblique and very 

 obsoletely bisinuate on either side, the medial lobe obtusely 

 rounded ; disk rather strongly but not closely punctured. 

 Scutellum trigonate, its apex acute. . Elytra convex, 

 metallic purple, the extreme apical margin rufous ; much 

 more strongly punctured than the thorax, the punctui'es 

 arranged in longitudinal rows at the sides and towards 

 the apex, rather less regularly placed on the inner disk ; 

 interspaces plane, obsoletely convex near the apex, thick- 

 ened and subcostate near the lateral margin.
