132. Agrilus aureoviridis. (Tab. VII. figg. 6, 6 a.) 



Aureo-viridis, nitidus ; capite inclinato, rugoso, medio impresso ; thorace fortiter punetato, basi medio foveata, 



angulis posticis inflatis ; elytris crebre asperato-punctatis, punctis cuneiformibus. 

 Long. 4| lin. 



Eab. Mexico, Etla (Salle), Chilpancingo in Guerrero 4600 feet (H. H. Smith). 



The head is rugose, with a slight impression above the clypeus and a larger trian- 

 gular not well-defined one on the forehead. The thorax is strongly punctured, the 

 punctures being placed close together so as to form shorter or longer curved lines, 

 leaving narrow spaces between the lines; the median impression is rather deep, 

 moderately broad at the base, narrowed anteriorly, extending a little beyond the middle 

 of the disc. The elytra have the subcosta slightly marked ; the punctures are cunei- 

 form, not crowded, but often touching each other in a transverse direction ; at one 

 quarter from the base a slight pubescent spot may be traced just within the subcosta 

 and another (rather longer) at about one third from the apex, both being indistinct ; the 

 apex of each elytron is rounded and finely serrulate. The prosternal chin-piece is 

 rather deeply emarginate. The prosternum is strongly and not very closely punctured ; 

 the intercoxal process is scarcely convex, obliquely narrowed at the apex. The episterna 

 are closely punctured, with a very narrow line of pubescence on the outer edge. The 

 abdomen is finely punctured ; the lateral carina of the basal segment is distinctly sinuous 

 about the middle, slightly so at its apex, with a yellowish-grey spot above each curve 

 (fig. 6 a). 



133. Agrilus perlucidus.

According to a specimen compared with Gory's type by Mr. Edward Saunders, this 

 species is quite distinct from A. aureus, with which it is associated in the Munich 

 Catalogue. The lateral carina of the basal segment of the abdomen is nearly rectilinear 

 posteriorly, whilst it is distinctly interrupted by a notch behind the middle in 

 A. aureus &c. 



The specimens from Cuernavaca differ from Mr. Saunders's example in being a little 

 less dull, and they have the subcosta of the elytra slightly smooth ; they bear the 

 name "A. rugicollis, Sturm."
