blackish ; elytra o£ silky, opaque appearance, with four flavous 

 spots placed in a row near the suture and three others at the 

 lateral margin, these spots show some fine punctuation ; underside 

 and legs black, the last three abdominal segments flavous. 



Hah. Eio Grrande, Brazil. 



This is a curiously marked species and not difficult to recognize ; 

 the thorax has scarcely any flattened sides, but a narrow reflexed 

 margin, and is entirely impunctate ; the short antennae, silky elytra, 

 and the spots will further assist in the recognition of the species. 



(Edioistchis sexsignatxjs (Clk. Catal.). (Plate XXXVIII. 

 fig. 2.) 



Fulvous or piceous, the head, antennae, and the legs black ; thorax 

 flavous, impunctate ; elytra greenish or violaceous black, each with 

 a round spot at the base, a transverse band at the middle, another 

 spot below the latter, and a short lateral stripe near the apex, as 

 well as the lateral margin, flavous. 



Length .3 lines. 



Head impunctate, black, the clypeus flavous ; antennae black, the 

 lower two joints obscure piceous below, the third joint slightly 

 shorter than the fourth ; thorax rather convex, the sides rounded, 

 with a broad flattened margin, the anterior angles thickened and 

 produced forward, anterior and posterior margins nearly straight, 

 the surface impunctate, flavous ; scutellum black ; elytra not percep- 

 tibly punctured, black or bluish black, a round spot near the scutel- 

 lum, a similar one near the apex and close to the suture, a narrow 

 obUque short stripe joining the similarly coloured lateral margin 

 below the posterior spot, and a narrow transverse band at the 

 middle flavous ; legs black or piceous. 



Hah. Colombia. 



Closely allied toCE.lO-guttata, Eab., but the shape and the position 

 of the elytral spots different, as well as the nearly smooth elytra. 



CEdiontchis afeioana, n. sp. (Plate XXXVIII. fig. 12.) 



Head, the apical joints of the antennae, and the breast black ; 

 thorax testaceous, finely punctured ; elytra testaceous, the suture, 

 a spot at the apex, a spot at the base, and an elongate mark at the 

 middle, black ; legs fulvous, spotted with black. 



Length 2 lines. 



Of nearly parallel and narrow shape ; head broad, black, punc- 

 tured near the eyes ; the antennae comparatively widely distant, 

 separated by a smooth space ; palpi piceous, the apical joint acutely 

 pointed, the penultimate one moderately incrassate ; antennae short, 

 the lower four joints testaceous, the others black, third joint dis- 

 tinctly longer than the fourth, terminal joints transversely widened ; 

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

 the anterior margin straight, the posterior one sinuate at the sides 

 and at the middle, anterior angles oblique, posterior ones acute, 

 the surface with a distinct sinuate transverse sulcus near the base,
