134. Agrilus restrictus. (Tab. VII. figg. 7, 7 a.) 



Cyanescenti-viridis, sat depressus, pariim nitidus ; thorace fortiter punctato, medio sulcato ; elytris confertim 



asperato-rugosis. 

 Long. 4| lin. 



Hab. Mexico, Pinos Altos in Chihuahua (Buchan-Hepburn). 



The head is somewhat arched downwards, closely and coarsely punctured, slightly 

 longitudinally impressed. The thorax is very strongly punctured, the punctures 

 slightly separated from each other on the disc ; the sides are gently arcuate ; the 

 surface is lightly impressed on each side at the front margin ; the lateral impression 

 extends somewhat on to the disc ; there is a swelling at the posterior angles with a 

 round fovea behind it close to the base ; the discoidal impression is broadly ovate 

 behind, narrowed in front. The scutellum is deeply impressed in the middle. The 

 elytra have the subcosta fairly well marked ; the rough sculpture is even and very 

 coarse. The prosternal chin-piece is slightly angularly emarginate. The presternum 

 is rather strongly and closely punctured, not pubescent ; the intercoxal process with 

 its margins slightly raised ; the apex is very obliquely narrowed, having the central 

 process at a slightly lower level. The episterna are rugosely punctured, slightly 

 pubescent on the outer half. The abdomen is moderately strongly punctured, slightly 

 wrinkled at the sides; the lateral carina of the basal segment with a slight but distinct 

 curve about the middle and at the apex, with a yellowish-grey pubescent spot above 

 each curve (fig. 7 a). 



135. Agrilus delectabilis. (Tab. VII. fig. 8.) 



Sat latus, depressus, cyaneo-viridis vel viridi- aureus, nitidus ; capite crebre fortiter punctato, medio sulcato ; 



thorace sat crebre fortiter punctato, medio sat late sulcato; elytris sat crebre subasperato-punctatis, 



guttis sex parvis albis notatis, apice serrulato. 

 Long. 4|-5 lin. 



Hab. Nicaeagxta, Chontales (Belt, Janson). 



The head has the surface rather uneven ; the median channel is rather deep and 

 wide, but well denned. The thorax is rather strongly punctured and the punctures 

 are distinctly separated from each other ; the median channel in some lights appears 

 divided in the middle, the posterior part being a little larger than the anterior, and 

 the punctures in the impression are close together and arranged in curved lines or 

 circles ; the posterior ridge is represented by a swelling, on the inner side of which 

 (close to the base) there is a small deep fovea (fig. 8). The elytra have the subcosta 

 distinct and shining; the punctures are triangular, generally separated from each 

 other, especially near the suture and below the scutellum, where the surface is smoother ; 

 each elytron has three small white spots — one just before the middle, another at some 

 distance from the apex, and the third halfway between these but outside the subcosta. 

 The prosternal chin-piece is very gently emarginate. The prosternum is rather strongly
