 quadrato, transversim fortiter ruguloso, medio leviter canaliculate ; elytris confertim rugosis, brevissime

This species somewhat resembles A. perlucidus, but is at once distinguished by the 

 angulated lateral carina of the basal segment of the abdomen &c. The thorax is rather 

 straight at the sides, evenly convex, narrowly impressed laterally, with no posterior 

 ridge or swelling ; the transverse or oblique rugse are strong and close ; the median 

 channel is narrow, distinct but not deep ; the surface is slightly pubescent. The elytra 

 have the subcosta very indistinct, except about the middle ; the pubescence is a little 

 congested near the suture behind the middle, but scarcely forms a spot ; the apex of 

 each is narrow and rounded, finely serrulate. The prosternal chin-piece is nearly 

 straight in front. The prosternum is rugose, slightly pubescent ; the intercoxal process 

 with its margins slightly raised, the apex a trifle widened and truncate. The episterna 

 are closely punctured, with a little pubescence on the outer half. The abdomen is 

 finely punctured ; the lateral carina of the basal segment strongly angulated about the 

 middle, pubescent above ; the second segment with a distinct whitish pubescent spot at 

 the side. 



65. Agrilus major. 



Crassus, subparallelus, supra subdepressus, cupreus, subtus aeneus ; thorace medio sulcato, crebre ruguloso, 



lateribus viridi-auratis ; elytris rugosis. maculis rotundatis quatuor ockraceis uotatis, apice serrulate.

The head is slightly flattened in front, rugulose ; with a longitudinal median impres- 

 sion, which is rather widened on the vertex. The thorax is coarsely rugulose, the rugae 

 curved; the median impression is moderately deep, subparallel; the posterior ridge is 

 represented by a narrow swelling ; the sides are greatly arcuate, slightly sinuate before 

 the hind angles ; the lateral impression is slight. The elytra are rugose ; the subcosta is 

 scarcely indicated ; each has a round yellow spot just before the middle, and another at 

 one third from the apex ; the apex is oblique on the outside and finely serrulate. The 

 prosternal chin-piece is very slightly arcuate. The prosternum (and metasternum) is 

 closely and coarsely rugose-punctate ; the intercoxal process is broad and parallel, nearly 

 truncate at the apex, a little advanced in the middle ; sparsely pubescent. The episterna 

 are coarsely and closely punctured, shining, with a little pubescence on the outer margin. 

 The abdomen is rather strongly punctured ; the lateral carina of the basal segment is 

 distinctly angular about the middle, with a pubescent spot above. The whole of the
