(Ediontchis pulchella (Chevr. in litt.). 



Black, the clypeus and thorax flavous, the latter impunctate ; 

 elytra finely and very closely punctured, fulvous, a niu-row trans- 

 verse band at the base, the suture, and a broad band below the 

 middle, nearly extending to the apex, metallic blue. 



Length 2| lines. 



Head rather closely punctured at the vertex, bluish black, the 

 frontal tubercles oblique, the carina indistinct ; clypeus flavous ; 

 antennae extending to the middle of the elytra, black, the lower 

 three joints flavous below, the third joint distinctly shorter than 

 the fourth ; thorax with rounded sides, leather strongly narrowed in 

 front, the anterior angles produced into a small tooth, posterior 

 margins straight, the surface impunctate, flavous ; scutellum black ; 

 elytra finely but distinctly and very closely punctured, the suture, 

 connected with and widened at the base into a narrow transverse 

 band which does not quite extend to the sides, and a broad and 

 nearly straight band immediately below the middle, extending to 

 the sides but not to the apex, metallic blue ; epipleurse flavous ; 

 underside and legs black, abdomen partly testaceous at the middle. 



Hah. Venezuela. 



If the blue colour of the elytra is taken for that of the ground, 

 they may be described as metallic blue, with a broad transverse 

 fulvous band, not extencUng to the suture, commencing directly 

 below the base and extending to the middle, and a small fidvous 

 spot at the apex ; the anterior edge of the fulvous band is very 

 convex and obliquely rounded towards the suture ; the blue colour 

 forms a triangular patch at the suture at the base and narrows to 

 a band near the shoulders ; the anterior margin of the posterior 

 blue band is nearly straight, the posterior margin rounded.

Black, the clypeus flavous, basal joints of the antennae fulvous ;

 verse band at the base and a similar band below the middle dark 

 blue. 



Length 3 lines. 



Head black, shining, with a few punctures near the eyes, the 

 latter widely separated, the frontal tubercles rather flat, subquad- 

 rate; the clypeus flavous, labrum and palpi piceous ; antennae fuscous, 

 the basal five or six joints fulvous, third joint distinctly shorter 

 than the fourth ; thorax bright flavous, the sides nearly straight, 

 flattened as usual, the anterior angles acutely produced into a tooth, 

 pointing outwards, the posterior margins somewhat rounded, the 

 surface convex, flavous, with a few minute punctures when seen 

 under a strong lens ; scutellum black ; elytra extremely finely punc- 

 tured, the posterior portion impunctate, the blue transverse bands
