new species of Eumolpidce. 47 



face finely and irregularly but not very closely punctured ; 

 interspaces smooth and shining, sometimes finely granu- 

 lose and subopaque. Scutellum semioblong-ovate. Elyti'a 

 much broader than the thorax, oblong ; above very convex, 

 the humeral callus strongly thickened ; surface rather 

 closely punctured, interspaces sometimes smooth and 

 shining, and only impressed with a few minute punctures ; 

 in other sjoecimcns distinctly rugose, every stage being 

 found between the tAvo extremes. Legs robust. 



This variable sjjecies is apparently very abundant in 

 Brazil, and from its large size and Ibrilliant colours has 

 attracted the notice of most collectors. I have received it, 

 although less commonly, from Cayenne and other parts of 

 South America. Its elytra are, as a ride, more coarsely 

 punctured than in any other species of the genus ; the 

 V-form of the abdominal fovea, which is not produced to 

 the outer margin of the segment, together with the short 

 telum,Avill distinguish the ^ from the same sex oiE.fulgidus 

 and allied species ; the ? may be separated by the peculiar 

 form of its presternum.
