Length 3 lines. 



Head black, the extreme base with a few punctures, the space 

 surrounding the eyes and the sides of the clypeus flavous ; antennae 

 not extending to the middle of the elytra, black, the lower three 

 joints and the apical one obscure piceous ; thorax rather strongly 

 convex, three times broader than long, the sides strongly rounded 

 in front, the anterior angles not produced outwards, the sides with 

 a broadly flattened margin, posterior margin sinuate at each side, 

 the surface impunctate, flavous ; scutellum black ; elytra very finely 

 but not very closely punctured, with a double row of deeper 

 punctures within the shoulders, black, the extreme and thickened 

 lateral margin, as well as the epipleurae and a rounded spot at 

 the extreme apex, flavous ; some rows of deeper punctures also 

 accompany the lateral margin ; underside and legs black ; sparingly 

 pubescent. 



Hab. Brazil. 



Allied in coloration to (E. ecctrema, Har., from Mexico, but in 

 that species the thorax has mucronate angles, the epipleurae within 

 as well as the underside and legs are piceous, and the elytra are 

 blue. 



(Ediokychis apicata (Clk. Catal.). (Plate XXXVIII. fig. 9.) 



Black, the sides of the thorax flavous, the surface impunctate ; 

 elytra dark violaceous or purplish, impunctate, the apex with a 

 round flavous spot. 



Length 3 lines. 



Head impunctate, black, shining, the frontal elevations entirely 

 wanting, carina acute, palpi flavous ; the antennae not extending to 

 the middle of the elytra, black, the first joint stained with fulvous, 

 the apical one entirely of that colour, the second and third joints 

 very short, subequal ; thorax with the anterior margin deeply 

 concave, the anterior angles very prominent but not produced 

 outwards, the sides evenly rounded, the surface impunctate, black, 

 shining, the sides broadly pale flavous ; scutellum black ; elytra 

 obscure metallic purplish or violaceous, impunctate, the apex of 

 each elytron with a round flavous spot ; underside and legs black. 



Hab. Brazil. 



This species may not only be recognized by its coloration, but 

 by the absence of any frontal elevations ou the head and by the 

 short second and third joints of the antennae. 



CEdionychis mobosa, n. sp. 



Black, opaque, impunctate, thorax and elytra narrowly margined 

 with flavous. 



Length 3 lines. 



Of a uniform black, opaque colour ; the head impunctate, the 

 frontal tubercles narrowly transverse ; the antennae black, short, 

 the third and fourth joints equal ; thorax twice as broad as long, 

 the sides rounded in front, straight at the base, anterior angles 

 produced forwards, without acute tooth, rather blunt, the surface
