 and mouth testaceous, the former closely punctate in front of the 

 eyes, nearly smooth in the middle, with a greenish V-shaped mark ; 

 antennae reaching to the base of the thorax, with the first four 

 joints testaceous, the rest more or less stained with greenish black ; 

 thorax with the front margin slightly convex in middle, and the 

 sides evenly rounded, surface closely and distinctly punctured at 

 the base only, the rest sparingly and very minutely ; a subquadrate 

 greenish black patch narrowed towards its base occupies the middle

 less stained with fuscous, smooth ; elytra very little wider at the base 

 than the thorax, semiflattened, of a greenish or brownish tint, 

 irregularly and rather closely punctate-striate, with fine transverse 

 and longitudinal scratches, the lateral margin from the shoulder to 

 the apex testaceous, only punctured near the inner edge, the outer 

 half perfectly smooth with the exception of a single row of rather 

 deep punctures near the extreme margin. Body below, with the 

 exception of the mesosternal process, the tibiae externally, and the

 eye), the strise arranged in single rows, of which the first is short 

 and the seventh disturbed by a few extra punctures near its middle ; 

 the interstices also extremely finely punctate, of a light olive-green 

 colour, with the suture narrowly, the lateral margins more distinctly, 

 part of the extreme base, and, connected with it, a common sutural
