anteriorly ; elytra closely and distinctly punctured, pale flavous, 

 the lateral and sutural margin, a transverse band at the base, and 

 another below the middle ferruginous. 



Length 2| lines. 



Head impunctate, ferruginous, shining, the frontal elevation 

 scarcely raised, the carina acute ; antennae short, black, the lower 

 two joints more or less flavous, the fourth joint very elongate, 

 quite double the length of the third, the following joints short, 

 equal ; thorax but slightly narrowed anteriorly, the sides nearly 

 straight, the anterior angles not produced outward, the surface 

 impunctate, yellowish white, the anterior margin with a ferrugi- 

 nous spot at the middle ; scutellum fulvous ; elytra closely and 

 rather strongly punctured, of the same colour as the thorax, the 

 base with a narrow transverse brown band, which is connected by 

 the lateral and sutural margins with a similar band below the 

 middle, these bands have a slight tinge of purple ; if the dark 

 colour is taken for tha.t of the ground, the elytra may be described 

 as browTi with a large discoidal ovate spot and the apex whitish ; 

 underside and legs ferruginous, tibiae and tarsi rather darker. 



Hah. Sta. Catharina, Rio Janeiro, Brazil ; also Bolivia. 



CEoioiirTCHis CRFCiTERA, n. sp. (Dej. in Utt.). 



Black ; thorax flavous, impunctate ; el}i;ra finely punctured, 

 metallic blue, a rounded spot at the base and a more transverse 

 one below the middle, not extending to either margin, flavous. 



Length 3| lines. 



Head entirely black, scarcely punctured ; antennae nearly ex- 

 tending to the middle of the elytra, black, the intermediate joints 

 slightly widened, the third joint only half the length of the fourth ; 

 thorax three times broader than long, flavous, the sides broadly 

 flattened, bounded within by a deep longitudinal groove, the 

 lateral margins rounded in front, the anterior angles dentiform, 

 the surface impunctate ; scutellum black ; elytra widened at the 

 middle, broadly margined, the shoulders prominent, bounded 

 within by a deep depression, very finely punctured, the apex 

 impunctate ; underside and legs black, the last abdominal segment 

 of the male with a broad, rounded, and produced medial lobe. 



Hah. Brazil. 



If the flavous colour of the elytra is taken as the ground-colour, 

 the blue portion extends across the middle in shape of a narrow 

 and somewhat oblique band, and a triangular patch is placed at 

 the apex, all the margins are also narrowly blue; the epipleurae are 

 flavous within, bluish at the outer margin. The species named by 

 Clark (E. murrayi, in his Catalogue, does not differ from the present 

 one except in the black, not blue, elytral markings. 



CEdiontchis cetjx-nigba (Chevr. in Utt.). 



Black ; thorax flavous, impunctate ; elytra rather closely and 

 strongly punctured, flavous, the base, suture, a lateral stripe
