616 ME. MARTIN JACOBY ON NEW [Nov. 6, 



a broad transverse band at the base, not extending to the sides 

 and anteriorly as far as the shoulders, an equally broad band 

 below the middle touching the lateral margins and the apex, 

 metallic blue ; the epipleurae, underside, and legs flavous, the 

 femora rather darker, the tarsi piceous. 



Hah. Colombia. 



A small species, differing from somewhat similar coloured ones 

 by the blue apex of the elytra ; the flavous bands dividing the 

 metallic colour are narrow, but the central band is wider than 

 that which separates the posterior band from the apical spot. 



(Edionychis trimactlata (Ok. Catal.). 



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

 elvtra convex, testaceous, closely punctured and finely rugose, a 

 transverse band at the base and a subtriangular spot below the 

 middle bright metallic blue. 



Length 4 lines. 



Head bluish black, sparingly but distinctly punctured, the 

 clypeus flavous ; antennas black, the third and fourth joints equal, 

 terminal joints shorter ; thorax with very strongly rounded sides, 

 flavous, the anterior angles produced but not dentiform, the 

 surface impunctate, the sides flattened ; scutellum black ; elytra 

 convex, rugose and closely punctured, testaceous, the base with a 

 transverse light blue band, not extending to the lateral margins, 

 and a large subtriangular spot of the same colour and transverse 

 shape near the apex ; underside and legs black. 



Hah. Colombia. 



Principally distinguished by the rugosely punctured elytra. 



(Edionychis osculans (Clk. Catal.). 



Black, the sides of the head testaceous ; thorax very minutely 

 punctured, testaceous, the disc with three black spots ; elytra very 

 finely and closely punctured, testaceous, a sutural, two discoidal, 

 and a sublateral stripe violaceous. 



Length 4 lines. 



Head greenish black, the space surrounding the eyes flavous, 

 strongly punctured, labrum partly flavous ; antennae black, the 

 extreme base of the first joint flavous, third joint much shorter 

 than the fourth ; thorax nearly three times broader than long, the 

 sides nearly straight at the base, rounded in front, the posterior 

 margin evenly rounded, the anterior angles tuberculiform, the 

 surface very minutely punctured, testaceous, a large spot at each 

 side and a small spot at the middle of the base greenish black j 

 scutellum greenish : elytra extremely finely punctured, with four 

 narrow longitudinal stripes, a sutural one, two at the disc, joined 

 at the apex but not extending to the latter, and a sublateral 

 broader stripe which joins the sutural one at the apex ; elytral 

 epipleurae flavous ; underside and legs black.
