624 ME. MABTIN JACOBY ON NEW [Nov. 6, 



entirely inipunctate, black, opaque, all the margins narrowly 

 flavous, the sides but narrowly flattened ; scutellum black ; elytra 

 without any punctuation, of exactly similar coloration as the thorax ; 

 underside and legs black. 



Hab. Rio Grande do Sul, Brazil. 



This species will be easily known by the sombre coloration, the 

 proportionally long thorax, and the entire absence of any sculp- 

 turing. 



(Edionychis fasciaticollis (Clk. Catal.). (Plate XXXVIII. 

 fig. 5.) 



Black or piceous ; thorax fulvous, with a transverse black band, 

 impunctate : elytra flavous, a transverse band at the base, angulate 

 at the shoulders, another broader band below the middle, widened 

 at the suture, and a spot at the apex black or fulvous. 



Length 3 lines. 



Head with a few fine punctures between the eyes, black, rather 

 flattened, the frontal elevations obsolete, carina short and thick ; 

 antennae extending to the base of the elytra, black, the basal three 

 joints dark fulvous, third joint slightly longer than the second but 

 a little shorter than the fourth joint ; thorax with the anterior and 

 posterior margins rounded, parallel, the sides strongly rounded, the 

 anterior angles slightly produced outwards, the surface impunc- 

 tate, fulvous with a black transverse band, not extending to the 

 sides, the edges of this band irregularly notched ; scutellum black : 

 elytra wider at the base than the thorax, widened at the middle, 

 finely and closely punctured, flaA*ous, with a narrow transverse 

 black band at the base which turns downwards at the shoulders to 

 about one third the length of the elytra, but does not extend to 

 the lateral margin ; another broader band is placed below the 

 middle, this band extends quite to the sides, widens at the suture, 

 and has the anterior and posterior margins deeply sinuate or 

 dentate, it is connected by the suture with a small spot at the 

 extreme apex : underside and legs black. 



Hab. St. Paulo, Brazil, also Bolivia. 



The band at the thorax is in some specimens divided into two 

 spots, and the elytral bands may be of bluish-black or fulvous 

 colour; their shape and position will help to distinguish the present 

 species from others having transverse bands. 



(Edionychis bbunneofasciata, n. sp. (Plate XXXVIII. fig. 8.) 



Below fulvous, above testaceous, head fulvous ; thorax scarcely 

 perceptibly punctured, testaceous ; elytra very finely and closely 

 punctured, testaceous, two elongate spots at the base and a trans- 

 verse band at the middle, not extending to the sutural or lateral 

 margin, pale brown. 



Length 4 lines. 



Head fulvous, shining, with a few punctures near the eyes and 

 a deep transverse groove between the latter, frontal tubercles 

 transverse, strongly raised, carina and clypeus also strongly swollen ;
