 Long. 7| lin. 



General form of E. sulcata, but with the thorax less ample; 

 the shoulders of the elytra are more prominent, and are more 

 excised immediately below. Bright bluish green, shining; 

 clypeus rather thickly and finely punctured. Thorax convex, 

 rather obscurely and not very thickly punctured. Scutellum 

 smooth. Elytra with the suture much raised; each elytron 

 with four slightly sinuous impressed lines, which are very 

 obscurely punctured ; the second and fourth interstices narrow 

 and costiform ; the first and third interstices have a few large 

 punctures in a line. Pygidium with punctures scattered over 

 the surface. In the female the three teeth of the anterior 

 tibise are a little closer together than in the male.

Very close to E. picipes; but, besides the coloration, it 

 differs from that and all the other species in having the base 

 of the thorax gently arcuate, and not at all sinuate before the 

 scutellum. Thorax convex, finely coriaceous, the sides sub- 

 parallel and gently sinuate behind the middle. Elytra each 

 with five black stride, the deflexed margins not bounded above 

 by a marked ridge. Pygidium obscurely and not very thickly 

 punctured. Anterior tibia? with three strong sharp teeth. 

 The coloration closely resembles that of E. puncticollis, W., 

 but that has the thorax thickly punctured, and has a slight 

 sinuation before the scutellum. 



Euchilia tar salt's.

Clypeus deeply incised, finely punctured ; the forehead more 

 distinctly punctured, and having black hairs arising from the 

 punctures. Thorax convex, thickly and strongly punctured, 

 the base very gently arcuate, not perceptibly emarginate before 

 the scutellum. Elytra each with six well-marked impressed 

 sinuous lines, which are strongly punctured ; the suture and
